Developments And Possiblilities Of Solar Power

Developments and Possiblilities of Solar Power
Solar power has been around for many years. The very first silicon based photovoltaic was invented
by Bell Labs back in 1954. At this time the cost per watt was high at $285 and in 2009 it dropped to
a mere $3.00 per watt (Solar Tech USA, 2014). Solar energy dates back as far as the 2nd century
with the Greeks and Romans starting fires through broken glass. Indirect benefits from solar have
been used way back to even photosynthesis (Bengtson, 2012). Passive solar energy was used to heat
building by using the design to capture the sun for heating and lighting. Moving into the 20th
century major changes have accrued and there is now concentrating solar power technologies for
centralized solar thermal plants (Bengtson, 2012). The public believes that solar is not yet ready to
take charge and become a major source of power, yet some experts disagree. Solar power in the 21st
century has magnified many possibilities for solar use. Photovoltaic has created a large economic
benefit by reducing the cost of other resources as well as its own for example solar heated water
heaters have cut the cost of gas and electricity (Bengtson, 2012). Germany is a great example of
how solar is in huge demand and working well to serve the consumers. Germany has 5 times the
solar power the United States is currently using although Germany does not get a great deal of sun
(Brad Plumer, 2013). Germany is the world leader in solar power and with the use of other

Solar thermal power generation technologies
Solar Thermal Power systems, also known as Concentrating Solar Power systems, use concentrated
solar radiation as a high temperature energy source to produce electricity using thermal route. Since
the average operating temperature of stationary non–concentrating collectors is low (max up to
1200C) as compared to the desirable input temperatures of heat engines (above 3000C), the
concentrating collectors are used for such applications. These technologies are appropriate for
applications where direct solar radiation is high. The mechanism of conversion of solar to electricity
is fundamentally similar to the traditional thermal power plants except use of solar energy as source
of heat.
In the basic process of conversion of solar into heat energy, an incident solar irradiance is collected
and concentrated by concentrating solar collectors or mirrors, and generated heat is used to heat the
thermic fluids such as heat transfer oils, air or water/steam, depending on the plant design, acts as
heat carrier and/or as storage media. The hot thermic fluid is used to generated steam or hot gases,

which are then used to operate a heat engine. In these systems, the efficiency of the collector reduces
marginally as its operating

We Needs Energy For A Successful Existence Essay
Introduction
The humanity needs energy for a successful existence. However, the amount of fossil fuel is
decreasing every day. Proved global reserves of oil and gas, at current rates of consumption, would
be adequate to meet demand for another 40 and 60 years, respectively. Moreover, using of
traditional sources of energy causes the greenhouse gases emission. These gases keep heat energy of
electromagnetic waves at lower atmosphere. The process that produces this difference between the
actual surface temperature and the effective temperature is due to the atmosphere and is known as
the greenhouse effect.
One of the main consumers of fossil fuel and source of the greenhouse gases is buildings. The
solution of this problem is "upgrade" our houses; make them smarter, environmentally friendly and
effective. Moreover, the smart homes will have many devices, which will replace the big part of
routine tasks, and life of people will be much easier. (Stephene S. Intille, 2006). Governments
support the building of eco–buildings, because they emit less carbon dioxide. For example, in the
UK it planned to reduce emissions by 2050 (DECC 2011, 30). Moreover, building of eco–houses
will improve IT and alternative energy technologies. This paper will argue that building of eco–
houses is the best way of future architecture and building technologies.
At this research project, I used basic criteria. First of them is economic benefits for average income
people. Second criteria is the degree of

Improving Solar energy in the United States
Audience: Home owners
Executive Summary:
Solar energy has been in existence for a longer than any of us will imagine. Of course the sun is the
oldest and most basic source of energy. Solar technology has been in existence since the 7th century
B.C. Solar energy is a clean and renewable energy that does not have most of the problems fossil
fuels have. There are three types of solar technology that can be utilized in both our homes and
businesses. The three types of solar energy are solar thermal and solar electric which can also be
called photovoltaic (PV) and passive solar energy. Solar energy is developing and could be used as
an alternative for fossil fuel which emits dangerous gasses into the atmosphere. I will be discussing
about the benefits, problems and how solar energy can be improved in the United States.
Introduction:
The sun has been around since the beginning of time and it is one of the most efficient ways of
generating electric power. Passive solar energy is simply the heating of home and buildings through
architectural designs. Solar thermal energy is where the sun rays are used to heat our homes and
water. It uses solar thermal collectors to collect heat energy and disperse it through our heating and
plumbing system. This type of solar energy is very cheap and can be afforded by home owners.
Solar photovoltaic uses the sun rays to electricity

Statement of Purpose
For this report, I will conduct extensive research pertaining to the idea of solar renewable energy.
Within the research, I will look to inform the reader on advantages and disadvantages of solar
energy. Also, how solar energy will affect human in later years in the universe. Once research is
conducted the report will then be organized into an informational report. The informational report
will be shared with U.S solar marketers, John Barbour, and others whom are interested in knowing
more information about solar energy. The main objective of this report is to inform the reader on
specific advantages and disadvantages of solar energy.
Background
Solar energy is energy that is produced by the sun in the form of heat and light ("Solar Energy").
Solar energy is said to be one of the most widely available sources of energy. Solar energy is also
said to be one of the best renewable energy sources to choose from. Solar energy is said to be the
greatest of all renewable energy sources because it is plentiful and, solar energy is free
economically. Solar energy scientifically can be used to convert the sun's energy into either heat
energy or the energy can be converted into electricity. If solar energy is converted to electricity, it
goes through either two processes. The first process is solar thermal energy. Solar thermal energy is
a form of energy in which the sun is used to produce heat, that then the energy can be used in a
variety of ways

Advantages And Disadvantages Of Solar Power
ABSTRACT
Solar power has a vast potential. The industry is to see large growth in the upcoming future.
However, there are technical and cost limitations which hinder solar power's ability to become a
more influential global electricity source. Despite these limitations, solar power is utilized by many.
From homes in the Unites States to developing countries, solar power is making lives and the world
a better place. Governments must see the potential of solar power and push their country's energy
needs away from fossil fuels and towards renewable sources, such as solar power.

FINDINGS
The largest obstacle solar power has to overcome is cost. Solar power has high startup costs. Stated
in The Future of Solar Energy, "Currently, the estimated installed cost per peak watt for a residential
PV system is approximately 80% greater than that for a utility–scale plant, with costs for a typical
commercial–scale installation falling somewhere in between." These cost estimates often "include
costs for inverters, racking and installation hardware, design and installation labor, and marketing,
as well as various regulatory and ﬁnancing costs" (The Future of Solar Energy). Many do not want
to pay for the upfront costs of instillation of solar energy devices when an alternative energy
supplier is already in place. In order to successfully reduce our carbon emissions, governments must
become involved. Federal money must be allotted to the research and development of solar power
for it to become a viable energy source. In doing so solar power will become less privatized and
potentially more affordable. There has been recent growth in the solar energy due to "a 50%–70%
drop in reported PV prices (without federal subsidies) per installed peak watt", and a "current
federal tax subsidy for solar generation: a 30% investment tax credit (ITC)" (The Future of Solar
Energy). The reduction of PV prices and a tax credit is a positive aspect for solar power, but the
prices are still too high for the masses. The value of a renewable energy source is frequently lost
when

The Rapid Depletion Of Conventional Energy Sources And...
Abstract
The rapid depletion of conventional energy sources and scarcity of fossil fuels are the major energy
concerns. The renewable energy such as solar powered energy can be harnessed by using solar flat
plate collector. A solar flat plate collector collects heat by absorbing heat from solar radiation. The
performance of solar flat plate collector mainly depends upon the characteristics of working fluid.
Conventional solar flat plate collector uses water as heat transfer fluid but it gives lower thermal
efficiency. Nanofluids have superior thermal and optical properties that can be used to increase heat
transfer rate. So our aim is to design and develop solar flat plate collector using Nanofluid as heat
transfer fluid. 1. Introduction
1.1. (a) Introduction – Flat Plate Collector
A solar thermal collector collects heat by absorbing heat from sunlight. A collector is a device for
capturing solar radiation.
Flat plate collector consists of:
1) a dark flat–plate absorber,
2) a transparent cover that reduces heat losses,
3) a heat–transport fluid (air, antifreeze or water) to remove heat from the absorber, and
4) a heat insulating backing.
In water heat panels, fluid is usually circulated through tubing to transfer heat from the absorber to
an insulated water tank. This may be achieved directly or through a heat exchanger.
1.1 (b) Introduction of Nanofluid
A Nanofluid is a fluid containing nanometer–sized particles, called Nanoparticles. These fluids are

Solar Energy And Solar Power
Introduction
Solar energy is defined as the transformation of the sun's rays into useful forms of energy, for
instance, electricity and heat. The capacity of solar radiation a place receives depends on a variety of
factors such as geographic location, time of day, season, and local weather. According to Knier
(n.d.) photo voltaic and concentrating solar power cells are the two forms of sources to produce
electricity. Photo voltaic cells generate electricity directly using solar cells and concentrated solar
power cells generate electricity using steam. According to The World Bank – for the past three
years, India has taken a enormous step in forwarding and in implementing the green growth agenda
by producing 2,000 MW of solar power at the world's cheap tariff. Solar power is likely to reduce
India's usage of imports of diesel and coal. A number of measurements are probably taking to
generate 20,000 MW of solar power in future by 2022. The Solar industry is likely to create 200–
400 jobs in the industries like research, development and installation, for every 10 MW of solar
power generated. Hence, the government of India had taken enormous steps to increase the
productivity of the solar energy. This research report will discuss the effectiveness and the
limitations of solar power in India

The potential of solar energy is tremendous. We should take advantage of this opportunity and make
solar energy usage more common!
Since solar radiation produces so much energy, why aren't we using a lot more of it? Solar energy
does have some disadvantages. One of the major problems with solar energy is the intermittent
speed at which it arrives at the Earth's surface. This causes problems with consistency when heating
or lighting. Another drawback to solar energy is that it requires great space to be gathered in
effective quantities. This makes it difficult to place the solar panels in areas where space is costly,
valuable, or unavailable. A final reason why we are not using solar energy is because it is quite
costly. According to JC Solar Homes, it would cost a homeowner roughly one hundred to two
hundred thousand dollars to convert his or her home to solar energy. Obviously, this is not realistic
or reasonable for most people; therefore, solar energy is often overlooked as a serious possibility for
solving our approaching energy pandemic.
There are different types of commonly used solar energy conversions. Photovoltaic energy is
commonly called solar cell energy. PV is a non–mechanical device that converts sunlight into
electricity. Solar thermal heat is being used in swimming pools, space heating and to heat water for
domesticated uses. Solar thermal power plants use sunlight to heat a liquid which turns into steam.

The Future Of Australia 's Renewable Energy Industry...
The path to renewables in Australia in recent times has been met with a somewhat contentious
debate. In a time where "No challenge poses a greater threat to our future than a changing climate."
(Barack Obama, August 3, 2015) the plight of Renewables is of more importance than ever in our
history as a pillar on to which our highly carbon emitting society must rest, if we ever seek to reduce
the impact on our climate both government and individuals must seek out and adhere to serious
carbon abatement strategies. The idea of previous successful government involvement in the
renewable energy industry through regulation and initiatives may elude the everyday modern
Australian, marred with controversial schemes, which in hind sight were rolled out to fast without
sufficient regulations has seen relatively recent schemes reduced or even thrown out. However, it is
best to remind ourselves that some of Australia's rite of passage as a nation were through Renewable
energy projects. Examples of this such as the Snowy Hydro Scheme which at the time was named as
one of the civil engineering wonders of the modern world and the White Cliff Solar Power Station
which can be seen as a world first solar energy provider.

Also, some savings are achieved by using more efficient cooling technology to reduce grid
purchases. The retrofit therefore reduces the total energy purchased from the grid, but it also
modifies the hourly electrical demand profile. Both pieces of information are required to compute
the savings, because it is assumed that the grid pricing is demand–sensitive, such that the price per
kWh each month is a function of the load factor for that month. Load factor is defined on a monthly
basis as the ratio of the average power consumption for the month divided by the peak hourly power
consumption. The load factor measures the consistency of the demand over time, with high load
factors indicating a more consistent demand that is less costly for the utility to provide. The monthly
per kWh grid price is therefore inversely related to load factor.
To determine how the building retrofit would modify the grid electrical demand, the original
aggregate hourly demand is split, as was previously described, into heating, hot water, cooling, and
baseline plug load profiles. The cooling profile is scaled by 80% to estimate the electrical load for

They concluded that this lack of knowledge points to a gap in information about solar energy. Their
study also found that there is a nuanced relationship between environmental concern and the use of
solar energy, which means that people have very complicated and conflicting attitudes towards
gathering and processing data that is related to alternative energy. This affects their willingness to
learn about alternative energy sources. A study done by D. Fuchs and M. Arentsen (2002) supports
the findings of the Rai–Beck study as they found that a lack of knowledge of electricity supply
options and the negative consequences that come with electricity use is a barrier to the consumption
of renewable energy sources, such as solar energy. Faiers and Neame (2006) found that people who
have implemented solar systems at an earlier stage tend to be more knowledgeable on the subject of
solar energy. Faiers and Neame also found that knowledge on the subject of solar energy increases
the likelihood of buying solar systems.

Renewable Energy Vs. Solar Thermal Power Plants
2.1. Introduction The limited resources of non–renewable energy and the fluctuation of fuel price
have forced the world to find clean and economical natural energy resources by means of renewable
energy. Solar energy is a sustainable alternative option that can be utilized in various ways and can
be used in many applications. The world has experienced enormous enlargement in energy and fuel
consumption with lacking of energy resources. Moreover, the finite fossil fuel resource could not
cope up with the increasing energy demand. According to the World Health Organization, air
pollution is now the world's largest single environmental health risk. Lately, the statistics have
shown that air pollution is responsible for approximately two million deaths a year [1].
Conventional power plants are the major source of air pollutions due to toxic emissions such as
carbon monoxide and sulfur dioxide. Alternative power plants that work on renewable resources
have been dedicated for this purpose. Different types of renewable energy and solar thermal power
plants will be presented in this chapter.
2.2. Renewable Energy Recently, the constraints of reducing fuel consumption and pollution have
improved the efforts toward renewable energies. Renewable energy resources such as sunlight, wind
and water are eventually unlimited and are much more eco–friendly than fossil fuel. It can be used
directly as solar ovens and geothermal heating, or indirectly by creating another form of energy

A Research Study On Water Heating
Water heating accounts for (20–30%) share out of total residential electricity consumption in urban
areas. Economical and financial factors are the most important barriers followed by market
availability for penetration of solar water heater [5]. A study has been conducted to find out
determining factors behind adoption of various solar energy technologies: solar photovoltaic and
solar thermal options, collecting data from 296 respondents from Chennai. It has been found that
scarcity for electricity and carbon free operation are two most dominating motivating factors. A
single point estimation of economic viability showed that it is feasible for Chennai [6]. The life
cycle cost and payback period assessment has been done taking three cities in united states ( Los
Angeles, Atlanta and Chicago),two auxiliary systems (natural gas and electricity) and two types of
solar collector (flat–plate and evacuated–tube).It varies from 4 to 13 years for different
configurations [7]. Economic study has been conducted to calculate electrical energy savings,
payback period and cost of unit electricity saved. The domain of this study was: three locations
(Pune, Mumbai and Chennai) and two solar water heaters with capacity (250lpd and 375lpd).For
pune 250lpd was found to be most attractive option [8]. Financial and commercial viability of
domestic solar water heater has been assessed for Indian climate with lower capacity utilization and
low purchasing power of people. A comparison has been

A Report On Solar Thermal Energy
Solar Thermal Energy
Introduction
Solar thermal technology uses the sun's energy, instead of fossil fuels, to get cheap, environmentally
friendly thermal energy. This energy is employed to heat water or different fluids, and can also
power solar cooling systems. Solar thermal systems vary from solar PV systems that generate
electricity instead of heat.
World Solar Market
The world has giant solar energy resources that haven 't been greatly used so far. Alternative energy
presently accounts for a tiny share of world primary energy consumption, however its use is
projected to extend powerfully over the outlook amount to 2030.
The highest solar resource potential per unit surface area is within the Red Sea area. Australia
conjointly has higher incident alternative energy per unit area than the other continent within the
world. However, the distribution of solar energy use amongst countries reflects government policy
settings that encourage its use, rather than resource availability.
Australia receives a mean of 58 million PJ of radiation per annum, close to 10,000 times larger than
its total energy consumption of 5772 PJ in 2007–08. In theory, then, if only 0.1 per cent of the
incoming radiation may be regenerate into usable energy at an efficiency of 10%, all of Australia's
energy desires may be provided by solar power. Similarly, the energy falling on a solar Darwin,
Brisbane, Perth, Adelaide, Melbourne and Hobart farm covering 50km by 50km would be spare to

Finally, we can point out another main challenge for GREENoneTEC that is the rise of raw material
costs which have extremely increased since 1995 (the price of copper had increased by more than
150 percent in 16 years for example). Thus our company has to deal with this increase by looking
for opportunities to reduce the costs of production. It can play on economic scale, searching new
suppliers less expensive or even changing the conception of its products with different raw
materials. We can notice that GREENoneTEC is facing challenges related to the Asian competition,
to the search of new customers and to the lowering of its costs of production. The company needs to
confront these challenges to stand out from the other companies on the solar market and to ensure its
permanence. Solar industry The solar industry is divided in three main markets: the European solar
thermal market, the Chinese market and the market in other world regions. The industry is
segmented in two main types of solar thermal collectors, which are evacuated tube collectors (80 per

The Solar Of Solar Energy
Interest in solar energy has been growing in recent years. Solar energy is abundant, clean and
renewable. There are two main methods to tap solar energy, i.e. with PV cells and with solar
collectors. The former converts sun light directly to electricity while the latter collects the solar
thermal energy (heat) to be used for various applications. Solar collectors have been in existent for
many decades. Their usages are experiencing resurgence in the recent years due to the interest in
renewable energy sources. Strongly increased number of solar heating plants have been built and are
under construction throughout the world. The solar collectors used in the solar heating plants are flat
plate solar collectors and often the volume flow rate through the collector field is varying. The
integration of solar thermal systems into buildings to meet energy requirements of buildings (for
domestic hot water, space heating, air–conditioning and lighting) is supported by many researchers
in different parts of world. Many types of solar collectors are commercially available; they differ in
design and performance and, of course, in price. They have to meet different demands in operation,
configuration and meteorological conditions.
Thermal applications are becoming focal point with increasing attention in the solar energy research
area as it has high performance in energy storage density and conversion efficiencies. Solar energy
collectors are particular kind of heat exchangers that

The ongoing demand and patterns of industrial energy production and consumption are highly
unsustainable which may lead to face multiple challenges like global warming, greenhouse gas
emissions, geopolitical conflicts, consecutive fuel price rises and at last fossil fuel reserves

where entrepreneurs will make investments and thus opportunities will be created for new jobs. To
achieve sustainable development and alleviating poverty, most of the developing countries followed
the energy strategy to be focused on combating energy poverty by improving integration systems to
the reliable and renewable energy services, enhancing energy efficiencies and promoting renewable
energy to meet rising energy demand in industrial areas. Moreover, in reference to UNIDO (2007b),
potential of renewable and clean energy resources to protecting the environment is yet to be
realized. The G8 Summit Declaration of 7 June 2007 states: "Improving energy efficiency
worldwide is the fastest, the most sustainable and the cheapest way to reduce greenhouse gas
emissions and enhance energy security." [3,5–8, 52] However, in places without sufficient solar
energy supply, it's not possible to create solar energy system integration in industries or other
promising sectors. Now–a–days these industrial processes are using electricity or liquid or gaseous
petroleum fuels to meet the demand of industrial process

Al–Sulaiman et.al [Exergy modeling of a new solar driven trigeneration system] have used exergy
modeling in order to evaluate the exergetic performance of a novel–trigeneration system utilizing
parabolic trough solar collector (PTSC).
Solar PDCs concentrate solar radiation to a single focal point by means of one or more parabolic
dishes. PDCs have concentration ratios in the range of 600–2000. As a result, they are rather
efficient at thermal energy absorption and power conversion processes. Thus, PDC is selected to be
the prime mover for the integrated system in this study.
Absorption chillers can make use of renewable energy resources, such as solar, geothermal and
biomass, in order to generate cooling. The other benefits of absorption refrigeration systems are that
they do not cause ozone layer retrenchment, they make use of natural refrigerants possibly having
less CO2 emissions and they are independent of electric grids. The most common commercially
suitable absorption refrigeration systems are single and double effect systems. In double effect
absorption refrigeration systems, a secondary fluid (absorbent) is used to circulate and to absorb the
primary fluid (refrigerant). The success of the absorption relies on the selection of an appropriate
combination of absorbent and refrigerant. The most widespread absorbent and refrigerant
combinations in absorption refrigeration systems have

Although solar energy is provided for an environmental friendly option however there are studies
that reveal that it has health effect on humans as they produce toxins furthermore it has implications
on our ecosystems and the provision of goods, for example crops, and services, such as soil carbon
storage. As with any type of power plant, large solar power plants can affect the environment where
they are located. Clearing land for construction and the placement of the power plant may have
long–term impacts on plant and animal life by reducing habitat areas for native plants and animals.
Power plants may require water for cleaning solar collectors or concentrators and may require water
for cooling turbine–generators. Using ground water or surface water in some waterless locations
with major solar potential may affect the ecosystem. In addition, birds and insects can be killed if
they fly into a concentrated beam of sunlight created by a solar power tower. Another disadvantage
is solar panels' dependence on the weather. The more direct sunlight a solar panel receives the more
power it can generate. When the weather becomes cloudy, the output of the panels is dramatically

Water is pumped into solar panels where it is directly heated by the sun and then pumped into
storage tanks where it is stored. Direct systems are very effective but have a shorter life span when
compared to indirect systems. The reason being is that, the water chemicals erode the pipes and the
panels over time and hence have to be maintained regularly. Water inside the panels can freeze in
colder weather conditions which may result in damaging the system (Choosing a solar geyser,
2010). Figure 1–Direct System
Advantages of a Direct System
 Service water used directly from collector loop
 No heat exchanger – more efficient heat transfer to storage
 Circulation pump needs only to overcome frictional losses.
Disadvantages of a Direct System
 It is only convenient to use them in areas where it rarely freezes and the quality of water must be

really good.
Indirect systems use the same procedure but the geysers in this system have copper pipes that are
used as the heating coil. Water is separated from the water inside the tank by copper pipes in this
system. An antifreeze fluid circulates through the solar panels (Choosing a solar geyser, 2010). The
fluid flows through the collector and then through the copper pipes inside the storage tank. The
water is then indirectly heated. The indirect systems have a longer life span when compared to direct
systems as there is

Pros And Cons Of Residential Solar Power
This project is to identify the feasibility of residential solar power applications for the end–user, and
any pros/cons and cost analysis of any such undertaking. We will compile existing data to identify
how much grid electricity the average US household uses, how much they pay per kilowatthour

Solar power is not consistent or reliable enough to be the only option for power. This technology
relies totally on the sun so certain days we will be able to produce more power than others and at
night we might not be able to produce any. Which is why we will not be able to completely sever the
tie to conventional power generation. There has to be a method available to generate enough power
to meet demand without available sunlight. Although as technology progresses we may soon be able
to generate power from solar sources 24 hours a day. Modern solar power towers are being designed
to store excess heat transfer medium underground during the day as its heated and recycling it at
night to continue to generate steam for power production (Mills, 2004). But even with this ability we
will not be able to go solely to solar power but it can still supplement existing power and drastically
reduce the country's carbon

Saudi Arabi A Large Amount Of Energy
Abstract
There has been an increasing growth in the development of new energy resources that can compete
with the energy demands of the growing population of the world. In this manner, a number of steps
have been taken in the major parts of the world. Solar power is been in use since a long time. With
the increasing demands of oil and gas there is a rapid decrease in the supply of these natural
resources, and hence, the authorities are looking for alternative ways to supply the power to the
exceeding population of the world. Saudi Arabia is one of the richest countries in terms of natural

Besides having, a number of impacts on the humankind the sun also play a major role in providing
food to grow, for plants. The plants get energy and use it as an essential part of their food this
phenomenon is called as photosynthesis in simple words. Sun is nothing else but an unending supply
of energy. It was just a story of few years back when humans have had the idea of transforming this
unending energy into the one that can be used by them in a number of ways of the Solar Power.
The last two decades have played a major role in developing the technological factors related to
solar energy. With each passing day, the systems are getting more and more efficient, economical,
and reliable. The solar systems are much more help in many other ways to provide the energy needs
of the humans of this age. Solar energy is simply the energy of the sun that is stored and then used in
a number of ways. The sun creates a massive amount of energy that is transferred to our planet each
day. There are different types of technologies that are used by the human to store this energy and use
is different ways. The solar energy has a number of other impacts on the life on earth including the
fossil fuels development and their origin. Most of the energy that is demanded to run the function of

Introduction
The purpose of this research is to identify what Solar Energy is and how it influences the world in its
entirety. The subtopics of this research paper include its history, effect on people, effect on business,
effect on society and global implications. According to the Solar Energy Industries Association,
Solar Energy is the cleanest and most abundant renewable energy source available (Solar Energy
Industries Association). Technology has helped Solar Energy become accessible and to provide a
different resource to the planet. Solar Energy Technology is becoming a fast growing industry and
has been the root of many changes in the movement to promote an efficient global environment.
This research will allow a better understanding of the benefits of solar energy and how it can be
used to create a better future for society. Background & History
Solar energy has been around for centuries, even though the majority of us think it is new. Solar

energy goes back to ancient times, it is the energy produced directly by the sun. The solar power can

Solar Renewable Energy System
In brewing industry, 80% of overall final energy consumption is used in the form of thermal energy
where solar thermal can be used for brewing processes as below: steam generation, malting process,
stopping germination of grains, air cooling, conservation with hot air, power supplying of washing
machines, wither and kiln processes. Malting plants and breweries consume heat for their thermally
driven processes at temperature level ranges between 25°C to 120°C. It seems feasible to supply
heat at this temperature level which is not higher than the actual amount required but in reality the it
is often decided by the consumer which needs the highest temperature. The integration of solar
renewable energy system is necessary to reduce the exergy losses and CO2 emissions [17,21,24,25].
To utilize the organic matter from brewing residues, optimized heat recovery can supply its thermal
energy demand over resources. Theoretically, the full energy potential is not utilized so the pathway
is the conventional means of energy. However, the conversion of heat from energy gained from
renewable energy resources can ensure environment friendly beer production process for future. To
increase the overall energy efficiency, the integration of solar heat energy gained from solar thermal
collector technologies can be considered as a prospective alternative to fulfill the demands of typical
low temperature process heat.

Solar Energy Advantages And Disadvantages
Solar energy can be use today in a variety of ways. Probably because today, more and more people
are understanding the advantages of solar energy as our solar technology increases and the cost of
fossil fuels rises. Solar energy systems today can now used to power homes, cars, appliances in a
ways of like Photovoltaic panels, Heating water, Lighting etc. Solar Photovoltaic panels The most
common form of solar energy used today are photovoltaic solar panels, which absorb the sun's light
to create electricity. These solar panels can be attached to homes as a primary or secondary source of
electric power. They can also be used for small appliances and machines which only need small
amounts of electricity for use. Large scale photovoltaic panel plants have also been constructed to
provide power to many homes. Solar cels convert sunlight directly into electricity. Solar cells are
often used to power calculators and watches. They are made of semiconducting materials similar to
those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks
electrons loose from their atoms, allows the electrons to flow through the material to produce
electricity. This process of converting light (photons) to electricity (voltage) is called the
photovoltaic(PV)effect. Solar cells are typically combined into modules that hold about 40 cells; a
number of these modules are mounted in PV arrays that can measure up to several meters on a side.
These flat plate PV arrays can be mounted at a fixed angle facing south, or they can be mounted on a
tracking device that follows the sun, allowing them to capture the most sunlight over the course of a
day. Several connected PV arrays can provide enough power for a household; for large electric
utility or industrial applications, hundreds of arrays can be interconnected to form a single, large PV
system. Solar lighting One of the easiest way to improve home efficiency is to add outdoor solar
lighting to your property. Unlike traditional exterior lights, solar lighting requires no complicated
setup as the lights are wireless and harness sunlight during the day to circumvent the need for grid–
supplied electricity at night. Though solar lights are not yet as

Solar Energy Advantages
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever–evolving
technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten
salt power plants and artificial photosynthesis. It is an important source of renewable energy and its
technologies are broadly characterized as either passive solar or active solar depending on how they
capture and distribute solar energy or convert it into solar power. Active solar techniques include the
use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy.
Passive solar techniques include orienting a building to the Sun, selecting materials with favorable
thermal mass or light–dispersing properties, and designing spaces that naturally circulate air. The
large magnitude of solar energy available makes it a highly appealing source of electricity. The
United Nations Development Programme in its 2000 World Energy Assessment found that the
annual potential of solar energy was 1,575–49,837 exajoules . This is several times larger than the
total world energy consumption, which was 559.8 EJ in 2012. In 2011, the International Energy
Agency said that "the development of affordable, inexhaustible and clean solar energy technologies
will have huge longer–term benefits. It will increase countries' energy security through reliance on
an indigenous, inexhaustible and mostly import–independent resource, enhance sustainability,
reduce

The Pros And Cons Of Solar Energy
Did you know that the sun is one of the most key sources of renewable energy today? Solar Energy
could be the answer to the world's problems if we use it right. Solar energy is a very clean renewable
source of energy, that could stop global warming. Solar energy is created from the sun's light and
heat. It has many positive aspects of usage. One of the most positive aspect of solar energy is how
clean it is, it's one hundred times better than using fossil fuels. Solar can be used in many different
shapes, ways and forms. There are two main ways of converting the sun into energy. The first
method works through the use of photovoltaics, which creates electricity directly from sunlight
through a photovoltaic cell. The second main source of solar power is called Solar Thermal
Technology. In this process, the heat from the sun's rays are captured, harnessed, and then used to
conduct energy for a selected source. The sun heats and lights a solar panel and it converts it to DC
current, then the inverter converts the DC energy to AC and then you have electricity for your home;
the extra electricity gets credited on the grid. A lot of people have no idea how much amazing things
solar can do. Solar can power cars, run a steam engine, power cities etc. A lot of ignorant people in
this world who only care about money and don't care about the future of our earth are totally
oblivious to what solar can do. I picked this as my project to try and spread awareness on how vital
solar energy really is to us. I also don't think people understand how clean solar energy is, it doesn't
emit any greenhouse gases when producing thermal energy and electricity. The heat that comes from
solar and is turned into electricity and hot water is called Thermal Energy. Our Sun's rays heat up a
fluid then the steam given off from the heated fluid gives power to a generator that makes electricity.
Instead of using propane, solar hot water is one of the cheapest and easiest ways to get you started
with solar and it's amazing benefits.
Solar energy has many positive aspects of usage. The first positive usage of solar energy is that this
type of energy is 100% clean and there's no pollution involved. It is better than using fossil fuels
because

Advantages And Disadvantages Of Renewable Energy
It is easy to see the environmental and economic advantages of using the sustainable sources of
energy but we must also consider all the disadvantages.
One disadvantage of the renewable energy is that it's difficult to generate the same amount of
electricity that are as large as those produced by traditional sources of energy, such as fossil fuel and
coal powder plants generators. This may means that either we need to reduce the amount of energy
we use or we need to set up more such facilities to balance with the world's growing demand.
An other disadvantage of renewable energy is the reliability of supply. Renewable energy generally
relies upon the weather for its sources of power. Hydro–generators need a source of falling water or
rain. Wind turbines rely on wind to turn the blades and solar panels need clear sky and sunshine.
When weather doesn't provide these kinds of climate conditions, it's impossible for renewable
energy sources make energy from them. Government of many countries have adopted
comprehensive policy frameworks at national level to ... Show more content on Helpwriting.net ...
Although the price for installing Solar Powers Systems is high, in the future years solar panels have
potential not only return on their investment, but to save you significant amounts of money by not
paying for electricity bills. Solar Panels or cells use photovoltaic effect to convert the energy of light
directly to electricity. Solar cells are constructed from a semiconductor material, that is usually
silicon. Each solar cell contain many electrons. The electrons are not able to carry an electrical
charge in their natural state. Photons are being delivered within the suns rays, and when these
photons reach the electrons, the electrons are turned into conduction electrons, what means that they
are able to carry electrical charge to the

Renewable Resources For Solar Energy
Solar Energy is something that the entire world relies on every day. Without energy, the earth would
be dark, and nothing will be able to operate. Lately, there has been many concerns with the various
types of resources that are used to generate energy. Many resources that are used are non–renewable
resource. This means that the resources such as oil and coal are not grown or produced, they are
found in regions in specific sections of the world. These resources are also recognized as fossil
fuels. Researchers have been working for numerous years to find new ways to generate energy
without using these resources that cause issues for the environment. By using renewable sources
such as the sun, new ways to create energy have developed. Solar energy is energy that is created by
the sunshine. This sort of energy that derives from the sun can create electricity in households. With
new emerging technology, solar energy can perform different types of energy for diverse uses such
as heating water or generate electricity for a home. This alternative energy that goes beyond fossil
fuels can be extremely beneficial for the environment; However, there might be some downfalls for
a consumer if they needed to use solar energy to provide electricity.
The sun has been playing a very significant role for earth and humans. It has been the producer of
light and without it several things would not exist. Now another part that the sun is playing in
humanity is being a generator of energy. The

Parabolic trough collector tube I. Introduction General information Nowadays the energy
consumption is on such high level that scientists all over the world are looking for other solution.
The greenhouse effect is becoming more and more disturbing effect and some steps need to be taken
to at least prevent some of damages which it may cause. First of all, I will try to explain what
parabolic trough collector is. It is one of the types of solar thermal collectors which is straight in one
dimension and curved as a parabola in the other. As you can see in the picture 1. the whole device
can be divided into following parts: parabolic reflective mirror, linear receiver tube or heat
collection element, steel support structure/frame and a single–axis drive mechanism. Parabolic
trough solar field consists of hundreds or even hundreds of hundreds of solar collector located
parallel through the field. Every single collector assembly is an independently tracking subsystem so
that it makes the whole system more efficient. picture 1 A parabolic solar collector assembly
Parabolic trough collectors need to be designed as simple as possible, not to generate extra costs,
easy to assembly which also means they can be transported in sections to ensure accurate parabola
with high rigidity and to lengthen the field to its maximum (which can differ from several meters to
over 150 meters). The objectives of parabolic collectors are to explain why concentration is
important and what

Solar Energy Can Not Harm The Earth
"Even if we didn 't have greenhouse gases, were going to have to move away from fossil fuels, as
we 're going to run out. They 're finite, where as solar and wind are infinite." – Ted Turner. Solar
panels use the energy that comes from sunlight to give power. Low–temperature collectors are flat
plates generally used to heat pools. Medium–temperature collectors are also usually flat plates but
are used for heating water or air for residential and commercial use. High–temperature collectors
concentrate sunlight using mirrors and lenses. and are generally used for fulfilling heat requirements
up to 300 deg C / 20 bar pressure in industries, and for electric power production. Installation of

It is fuel free. Solar energy is the best source of energy because it uses the suns energy rather than
fossil fuels, is renewable and can be used anywhere. Solar thermal energy is the best source of
energy because it uses the suns energy instead of fossil fuels. As The Union of Concerned Scientists
state in the article "how solar energy works", "solar energy is a vast and inexhaustible resource.
Once the system is in place it converts the rays into useful energy and will never have ups and
downs of energy markets" (p1). Solar energy is inexhaustible because it does not use or give off
fuels. It is fuel free. Instead it uses the light from the suns rays and converts it into heat. Since it
doesn't use fuels but instead the suns energy it is a reliable source. There will always be light.
Further more National geographic in their article "solar energy" say that "using solar active
technologies is used to harness energy by mechanical devices and electrical devices to convert rays
into energy"(1). Mechanical devices and electrical devices harness energy. Since the energy is being
harnessed through electricity it is not using fuels nor giving off fuels while converting rays into
energy such as heat. Scientific american experts in the article "How does solar power work?" say
"the light hits certain materials which the energy turns

Energy : The Advantages And Disadvantages Of Wind Energy
In addition to being a virtually inexhaustible renewable resource, wind energy has the advantage of
being modular; that is a wind farm's size can be adjusted by simply adjusting the number of turbines
on the farm. A major disadvantage of wind is that the amount of energy available from the generator
at any given time is dependent on the intensity of the wind resource at the time which is very
difficult to predict. This intermittency of intensity reduces the wind generator's value both at the
operational level and also at the system capacity planning level where the system planner needs
information about how much energy they can depend on from a generator at a future planning date,
i.e., when the wind intensity cannot be perfectly predicted. Another disadvantage of wind energy is
that good wind sites tend to be located far from main load centers and transmission lines. Concerns
have also been raised about the death of birds and bats flying into wind turbines, the possibility of
turbines causing radar interference, and potential adverse effects of the shadow flicker5 on people
living in close proximity.
According to the estimates, onshore utility scale wind power plants have the lowest capital cost
among the renewables at $2,213/kW. In addition, wind has a lower capital cost than nuclear and
pulverized coal power plants. Offshore wind power plants, on the other hand, have an estimated
capital cost that is higher than all other generating technologies except municipal solid

As a result of these industrial farming conditions, today's mounting environmental stresses are
further exacerbated. These stresses include: declining water tables, chemical leaching, chemical
runoff, soil erosion, land degradation, loss in biodiversity, and other ecological concerns.
A more sustainable means of acquiring food is to purchase locally and seasonally. Buying food from
local farmers reduces carbon offsets, caused by long–distance food transport, and stimulates the
local economy. Local, small–scale farming operations also typically utilize more sustainable
methods of agriculture than conventional industrial farming systems such as decreased tillage,
nutrient cycling, fostered biodiversity and reduced chemical pesticide and fertilizer applications.
Adapting a more regional, seasonally based diet is more sustainable as it entails purchasing less
energy and resource demanding products that naturally grow within a local area and require no
long–distance transport. These vegetables and fruits are also grown and harvested within their
suitable growing season. Thus, seasonal food farming does not require energy intensive greenhouse
production, extensive irrigation, plastic packaging and long–distance transport from importing non–
regional foods, and other environmental stressors. Local, seasonal produce is typically fresher,
unprocessed and argued to be more nutritious. Local produce also contains less to no chemical
