Renewable energy, that's what we now have to think about!! In this era where the conventional sources are getting exhausted, prices soaring up, alternate must be brought in our daily life.
Renewable energy Sources, Efficiency, Uses and latest Research Zohaib HUSSAIN
1. Introduction
In today's world of climbing fuel prices, approaching the peak oil supply limit, and discussions of global warming, renewable energy is gaining more public attention and receiving more financial and legislative support. We need to learn more about the different types of renewable energy so that you can help educate your family, friends, and policymakers about ways to help our country move towards energy independence and environmental sustainability. According to a USAID report, Pakistan has the potential of producing 150,000 megawatts of wind energy, of which only the Sindh corridor can produce 40,000 megawatts.
2. Definition
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.
3. Types of Renewable Energy
Most Countries currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources such as wind and solar energy are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun's heat also drives the winds, whose energy, is captured with wind turbines. Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydroelectric power. Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called bioenergy.
Hydrogen also can be found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides come from the gravitational pull of the moon and the sun upon the Earth.
In fact, ocean energy comes from a number of sources. In add
What is Renewable energy , Why Do We Need Renewable Energy, various sources of renewable energy like Hydroelectric power or hydro-power, Wind energy, Solar Energy, Geothermal Energy, Wave power, Tidal power, Biomass fuel & Hydrogen Energy and details about them

Green energy - The sustainable energy source of the future 01262016Tony Green
Today we primarily use fossil fuels to heat and power our homes and fuel our cars. It’s convenient to use coal, oil, and natural gas for meeting our energy needs, but we have a limited supply of these fuels on the Earth. We’re using them much more rapidly than they are being created. Eventually, they will run out.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
20. Problems with hydroelectric
• Location = unused rivers are in
extreme north or low population
areas.
• Competition with recreational
uses and environmental concerns
• Hard to build dams in populated
river valleys
• Siltation of dams – limited life.
23. Oceans Power Plant Generators
• It converts kinetic power to
Electricity.
• Equipped with Kinetic energy
harvesters called floats.
• The floats moves up and down
with the motion of a wave.
• The motion of the float is
transferred to via hydraulics to
rotate power generators.
• Continuous production and a
smooth output
27. Geothermal
• The heat used for geothermal energy can be derived from deep with in earth.
• Heat conducts from core of surrounding rocks.
• High temp and pressure cause rocks to melt which is called “Magma”
34. Geothermal
• The world’s geothermal energy resources are 80 times more than all the
known oil reserves in the world.
• The research of Javed Ahmad was acknowledged by the US experts during the
US-Pakistan clean energy business opportunities conference held on
December 1-2, 2015 held in Washington DC.
• Javed said. The research has identified mud volcanoes, hot geothermal fluids
in Balochistan province and dormant volcanoes, hot magmatic waters at 150
degrees centigrade in Chagai volcanic Arc in Balochistan province. The
research has also pinpointed hydrocarbon basin related co-produced
geothermal waters with temperature of 80-170 degrees centigrade in Sindh. In
addition, there are 300 dry, depleted and abandoned oil and gas wells which
can be used for geothermal energy development.
38. • Turbine blades spin from the wind to
make energy
• Wind rotates the turbine blades
which spins the shaft connected to
generator.
• Each wind turbine can produce
between 0.25 to 2 MW
• It requires 15Km/hr speed of wind.
39. Wind Turbine Power
𝑃 =
1
2
∗ 𝑟ℎ𝑜 ∗ 𝐴 ∗ 𝐶𝑝 ∗ 𝑉3 ∗ 𝑁𝑔 ∗ 𝑁𝑏
P= Power in watts (746 watts = 1 hp)
Rho= air density (about 1.225 kg/m^3 at sea level)
A= Rotor area, exposed to the wind (m^2)
Cp= Coefficient of performance
V= wind speed in meters/sec
Ng= generator efficiency
Nb = bearing efficiency
40. Potential of Wind in Pakistan
• In Sindh and Balochistan there is a
potential of more than 50,000 MW.
• Total area of Sindh suitable for wind
farms = 9749 km^2.
average capacity factor of this area in
Sindh = 25%
• Punjab has the potential of 1000MW.
41. Question?
How many wind farms are there in Pakistan?
Name of that area and province?
• Three Gorges First Wind Farm
• Sapphire Wind Power Plant (ownership of Sapphire Textile and Bank Alfalah.)
• Metro Power Company Limited
All these plants are located in Jhimpir, district Thatta, Sindh
43. • It converts chemical energy to electrical energy.
• A fuel cell is an electro-chemical cell
• Hydrogen is the simplest and most abundant element in the universe
• It does not occurs naturally stable it self by doing reaction with others
Two methods of hydrogen electricity
1. Steam reforming
2. Electrolysis
Demerits
• Cost
• Lack of support infrastructure
• Storage (To stop hydrogen from doing reaction)

47. What has gone wrong with us
All governmental planning ,
mitigating actions, and
privatization, have backfired.
Technological solutions have not
worked; because it is not the dearth
of technology, it is the ‘mistrust’,
‘dishonesty’ and the distance
between ‘them’ and ‘us’.
48. Failure to build dams resulted
not a single Mw produced in 9 years.
IPPs have been struck with cash flow
problems.
Oil prices have soared high.
Today debt runs in billions.
49.
50. Mega projects are .. distant realities
Big businesses ….. are no more
feasible
What is available at the shelf…are
‘micro businesses’
Go micro…
Go indigenous…
and build people up
51. How to reverse the power crisis
Enable people produce their own
power from whatever sources
that are available to them. Block
the money sucked out, and to
divert it to improve the
generating capacities.
52.
53.
54. Quickest Approach
The quickest approach is building
up systems for self generation
through disbursement of
technology and development of
entrepreneurship.
