Renewable energy resources are becoming increasingly important due to concerns about energy supply and demand. As populations and industries have grown, the demand for energy has far outstripped the available supply of energy from fossil fuels. In response, interest has grown in developing alternative renewable energy sources like solar, wind, hydroelectric, and geothermal power. While hydroelectric and nuclear have provided some alternatives, most renewable sources still require additional energy input to be viable or have not been scaled up significantly. Improving energy efficiency through mechanisms like negawatt power can also help balance the supply and demand of energy.

New energy sources and energy efficiency to prevent catastrophic global clima...Fernando Alcoforado
Regardless of the various solutions that may be adopted to eliminate or mitigate the causes of global warming, the most important is undoubtedly the adoption of measures to contribute to the elimination or reduction of the consumption of fossil fuels in energy production as well as for their more efficient use in transport, industry, agriculture and urban areas (residential and commercial), given the use and production of energy account for 57% of greenhouse gases emitted by human activity. In this sense, the implementation of a world sustainable energy system is essential.

Renewable sources are expected to provide energy for almost 1 billion more years. Renewable energy includes electricity from solar, wind, hydropower and biofuels. Many countries get a significant portion of their electricity from renewables like Iceland which gets 100% from renewables. Renewable energy is growing and provides opportunities to lift nations to new levels of prosperity with low emissions.
Brazil faces threats to its energy sector from blackouts in power and fuel shortages. These issues stem from a lack of integrated planning between the electricity and oil sectors. Planning is done separately without rational use of energy sources. To address blackouts, Brazil needs to decentralize its electric system, increase redundancy, prioritize energy savings, and adopt cogeneration. Fuel shortages can be avoided by reducing consumption and increasing use of substitutes like ethanol and biodiesel rather than relying on imports. A new strategic energy plan is needed that utilizes renewable energy and engages stakeholders to achieve sustainable energy.
The Brazilian Conundrum_ More Hydropower, Greater Greenhouse Gas EmissionsAntónio Oliveira
This document examines how Brazil's strategy of expanding hydropower in the North will impact greenhouse gas emissions. Due to geographic constraints, most new dams will be run-of-river with limited storage capacity. As a result, Brazil's electric grid will lose its ability to regulate electricity supply over multiple months. This will force greater reliance on fossil fuel plants, even when not facing droughts, doubling Brazil's carbon intensity by 2022. While the emissions increase may seem small globally, it warrants attention as the problem could grow significantly in coming decades without changes to Brazil's energy strategy.
The document discusses the role of clean energy, specifically nuclear power and energy storage, in addressing climate change and transitioning away from fossil fuels. It argues that nuclear power can play a major role in minimizing climate change by producing little to no greenhouse gas emissions over its lifecycle. Energy storage is also seen as important for integrating renewable energy sources like wind and solar into the electric grid and enabling the transition off fossil fuels, as renewables have variable output that storage could help balance. The document examines both the technical and economic impacts of energy storage and variable renewables on the grid and their potential to replace fossil fuels as costs decline and reliability increases over time.
The Future Of Renewable Energy And RE Policy MechanismsSheri Elliott
The document discusses renewable energy policy mechanisms and the future of renewable energy. It notes that renewable energies can compete with fossil fuels if subsidies are leveled between the industries. Currently, fossil fuels receive over 85% of energy subsidies in the US. Investments in wind energy, stimulated by the production tax credit, have significantly lowered costs and increased domestic manufacturing jobs. For renewable energies to effectively replace fossil fuels, policies need to incentivize their growth and competitiveness.
Reduction in Energy Consumption Will Be the Only Option RemainingBruce LaCour
1) The document discusses how various distributed energy technologies like CHP, solar panels, and wind farms will not allow Americans to maintain current high levels of energy consumption and lifestyle.
2) While these technologies can improve efficiency, capture wasted energy, and reduce transmission losses, the large initial capital costs and need for fast returns often prevent widespread adoption.
3) The only real solution according to the document will be a program for massively reducing overall energy consumption, as population growth has outstripped available resources and maintaining the status quo is impossible given physical limits.
The document discusses appropriate technology and provides examples of renewable energy technologies that are considered appropriate. It describes how appropriate technology aims to solve social problems without negative consequences that outweigh the positive impacts. Renewable energy technologies discussed include biomass, hydropower, geothermal, wind, ocean, solar, and thermal solar power.

As you know, our world is heavily dependent on fossil fuels for me.docxdavezstarr61655
As you know, our world is heavily dependent on fossil fuels for meeting our energy needs. In Chapter 6 of Contemporary Environmental Issues, you have read that there is concern about the possibility of reaching a peak in oil production, and even coal and natural gas will eventually run out. (Next week, in Chapter 7 of the textbook, we will read about an even more pressing reason for no longer relying on fossil fuels: global climate change.) Chapter 8 of Contemporary Environmental Issues introduces a variety of possible alternative energy sources, including nuclear power and many renewable options like wind power and solar energy.
Next week, you will be participating in a collaborative project aimed at developing an alternative energy plan for a particular community – the details of which won’t be revealed until then. For now, let’s all pool our research into what possible energy choices might be able to help us move away from fossil fuels.
In your main post this week, please
· Identify two alternatives to fossil fuels that are currently available.
· Discuss the barriers that keep these alternatives from replacing coal, oil, and natural gas as our primary means of energy.
· Discuss the role that government plays in ensuring a transition to these renewable alternatives in a post-carbon world.
Be creative here – the ideas you explore now might become the building blocks for next week’s sustainable energy plan.

The document proposes building a solar power station on the moon to provide clean energy to Earth and address issues of unemployment, economic stagnation, and the national debt. The station would use parabolic concentrators made of lunar materials to heat lunar regolith gas and power Stirling generators, beaming 21 trillion kWh/year of electricity to Earth via microwave. This could generate $2.5 trillion annually for the US Treasury, eliminating deficits and debt while funding infrastructure jobs. The proposal has been made for over 34 years without response.
This document provides an overview of renewable energy development in South Africa. It notes that while South Africa still relies heavily on coal for electricity generation, comprising 93% of its energy mix, it is pursuing renewable energy more actively. South Africa has strong potential for solar and wind power. Notable developments include the Herbert 1 solar facility and plans for solar capacity to reach 8.4 GW by 2030. The country also aims to source 42% of new energy capacity from renewables by 2030. Challenges include transmitting solar energy from remote desert sites to cities.
Executive summary for Last Chance Saloon for CSP (Concentrated Solar Power)Simon Thompson
This is the executive summary for "Last Chance Saloon for Gen 3 CSP" which is a report and forecast from Rethink Energy.
It’s about the global Concentrated Solar Power (CSP) business which, although small compared to photovoltaic or wind power, will be a $10 billion global industry by 2030. How so?
Previous CSP marquee projects such as the “tower power” plants of the Mojave Desert have proved to be expensive and R&D-hungry. Although impressive, they’ve tarnished the sector and in recent years investment has gone elsewhere.
It means that CSP has effectively lain moribund for a decade.
But in recent years a new wave of technology-driven CSP companies have brought a swathe of minor innovations, improvements on efficiency and cheaper equipment to the market.
CSP can now provide temperatures of 1,000 degrees Celsius, enabling the technology to play a role in the decarbonization of the cement, steelmaking, and mining industries. And in China there are plans to use CSP on the power grid as “peak-shaving” energy storage.
Does this mean that this 3rd generation of CSP activity will lead to profitable returns? What are the new technologies and who are the players? And what will be the impact of the global demand for hydrogen on CSP?
The answer to these questions and more can be found in Last Chance Saloon for Gen 3 CSP in this 30-page report, illustrated with graphs and accompanied by an Excel spreadsheet with projections.

The fossil fuels industry, big oil, big coal, natural gas, and its allied sectors, including some large financial institutions, will not quietly or willingly retire into the history of ideas whose time has passed. That fossil fuels represent the single greatest systemic risk to our collective economic wellbeing, however obvious to increasing numbers of fiduciaries, is not a consideration for the industry’s plutocrats. A divestiture campaign to get money out of fossil fuels stocks has emerged, indicating an emerging popular awareness that we must and will transform our energy society into one that can coexist with and even thrive on a finite earth. That a massive global transition away from fossil fuels and towards renewable energies, led by solar, also means that there are and will continue to be competitive investment returns earned from carefully selected investment exposure to the sector.
This document discusses the advantages and challenges of wind energy. It outlines several key advantages, including that wind energy is a clean and renewable resource that does not pollute the air or use water. Wind power also provides economic benefits through jobs and additional income for farmers. However, the document notes there are also challenges to greater adoption of wind energy, including the need for technology improvements and lowering costs.
The document provides guidelines for writing a newspaper editorial on whether the government should play a greater role in the American economy. It instructs the editor to choose a current issue, establish a clear thesis, support the position with facts and examples from research, and use persuasive language to engage readers while balancing emotional and factual appeals. A sample editorial is also provided on the topic of energy efficiency, arguing that improving efficiency in appliances, buildings, vehicles, and industrial processes through standards and incentives is an effective way to reduce emissions while saving consumers money.
Geothermal energy refers to heat from the Earth that can be used to generate electricity or provide direct heating. Tapping geothermal heat has occurred for thousands of years, but its use expanded in the 20th century. Now, geothermal energy provides a significant portion of electricity in several countries and global potential is large. However, high upfront costs, exploration risks, and lack of awareness present barriers. Ground source heat pumps (GSHP) are also considered geothermal energy as they use shallow Earth temperatures for heating and cooling buildings efficiently. GSHPs have widespread applications and increased usage could provide climate and economic benefits.
The need for expanded nuclear energy is urgent. Global energy demand is expected to grow by at least 50% by 2035, with electric demand in the developing world expected to triple.
Presently, more than one billion people completely lack electricity access and billions more consume one tenth or less of the electricity per capita consumed in the OECD. Much of that supply is intermittent.
At the same time, 81% of the world’s energy, and two thirds of the world’s electricity, is derived from fossil fuels, while emissions from fossil fuel combustion are a major factor driving global climate change.

In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.

A toxic combination of 15 years of low growth, and four decades of high inequality, has left Britain poorer and falling behind its peers. Productivity growth is weak and public investment is low, while wages today are no higher than they were before the financial crisis. Britain needs a new economic strategy to lift itself out of stagnation.
Scotland is in many ways a microcosm of this challenge. It has become a hub for creative industries, is home to several world-class universities and a thriving community of businesses – strengths that need to be harness and leveraged. But it also has high levels of deprivation, with homelessness reaching a record high and nearly half a million people living in very deep poverty last year. Scotland won’t be truly thriving unless it finds ways to ensure that all its inhabitants benefit from growth and investment. This is the central challenge facing policy makers both in Holyrood and Westminster.
What should a new national economic strategy for Scotland include? What would the pursuit of stronger economic growth mean for local, national and UK-wide policy makers? How will economic change affect the jobs we do, the places we live and the businesses we work for? And what are the prospects for cities like Glasgow, and nations like Scotland, in rising to these challenges?

BRAZIL’S GIANT POWER SOURCE WAITS FOR ENTREPENEURSHIP
1. BRAZIL’S GIANT POWER SOURCE WAITS FOR ENTREPENEURSHIP
Paulino E. Coelho, Ph.D., wastepec@hotmail.com
In the early 70s, during the first oil crisis, Brazil started looking for alternative sources of
energy. By that time large hydropower projects were at its very beginning. Among
alternatives sought were solar and wind that by then used to have prohibitive costs and
low efficiency. On the other hand biofuels were also targeted by then. In the search for
other forms of energy Brazil had also tapped its geothermal potential.
With the success of the biofuel projects and after large hydropower plants and the
introduction of one nuclear power plant, besides improvements made in a couple of coal
power plants, most alternative energy projects were left behind.
Ten years later, practically all southeastern hydropower sources were developed and
another oil crisis had triggered an economic crisis in Brazil that lasted for an additional ten
to fifteen years. In this meantime all skills in large engineering projects have vanished.
From the mid-90s Brazil’s economy had a strong recovery, making it one of the largest
economies in the world and an emerging country. This called the interest of other
countries and foreign entrepreneurs that have seen in the country a great opportunity for
making money. Economic growth also demanded more energy that the country didn’t
prepared for. With this, new frontiers for large hydropower plants had risen, making room
for large projects in the so called west-center of the country and nowadays the Amazon
region.
However, natural delay between project design and energy supply allied to justified
environmental pressures, turned it possible new ventures in alternative energy supply.
The, up to then, so called little reliable, low efficiency, high cost, wind energy, took a new
breath, mainly due to the interest of foreign investors in making money in Brazil.
Wind power energy suppliers and makers from all over the world, brought their experience
to the country and had succeeded in, once for all, introducing this energy source in Brazil,
with great emphasis in the Northeastern part of the country. Prices became competitive
with other sources of energy and supply trust was considered reasonable for the
consumption of the areas where projects were introduced. This example must be followed
by other entrepreneurs with other energy sources.
One problem that arose from the energy source expansion, not only in terms of
alternatives, but also in terms of geography, was distribution. Nowadays there are power
plants that are ready to supply energy but do not have a way of distributing it. It is
2. common to have communities around a very large wind power plant without energy
supply due to lack in distribution lines.
Because of economic interests Brazil still follows the not sustainable way of providing
energy by means of large plants and not self-generation, which has shyly started in the
country. Next step is to build giant solar farms.
Regardless of trends or wrong doings, history has shown that although changing ideas
come through, only long time after and with foreign risk takers and entrepreneurship these
ideas are developed in Brazil, mainly if the country does not have the experience or the
skills to develop them. Research in Brazil is mainly concentrated in the hands of the
government and, researchers, as well as universities, in Brazil, are far apart society
needs. Pure and frontier research are the main targets in the research area in Brazil, and
not applied or technological research that the country badly needs. Once again, this
behavior gives room to foreign skillful and experienced entrepreneurs to bring their
technology and invest them in Brazil in order to obtain results. One example to be
followed is from people in the wind energy area. Plants in Brazil far exceed the largest
size of most wind energy farms all over the world. Size of the country, population,
economic growth and energy demand makes Brazil the ideal country to invest in known
energy sources available in the country, but whose technology is overseas. This is what
makes the reason for this article.
There are two GIANT power sources in Brazil almost completely forgotten and
unexploited in the country, that could be developed in a very sustainable way, by small
projects, and, at the same time, by means of large power supply schemes. They are
GEOTHERMAL energy and ENERGY FROM THE OCEAN.
For long time GEOTHERMAL energy was restricted to volcanic or tectonic plaques
borders areas. However, with the development of new binary plants, as for example
KALINA plants, the use of fluids with lower vapor pressure, turned it possible to use this
source of energy in areas where ground temperatures are not as high as in so called
tectonically active areas. In addition to that, ground temperatures stabilization makes the
Earth, wherever you are, an ideal heat exchanger, turning it an ideal AIR CONDITIONER
anywhere. This means energy saving all over the world and an additional energy source
for air comfort, including in Brazil.
However, contacts with important Brazilian Engineering Procurement and Contracting
(EPC) companies have shown they are very resistant to the idea of trying the use of
GEOTHERMAL energy for air conditioning or power generation. Although the technology
already exists and is commercial overseas they are not sure how to make it work in Brazil
and if it is possible to make it work here. On the other hand they also do not want to invest
3. to have the answer. In addition government research sponsors do not consider this a
priority area to invest, mainly considering this is known technology. This was exactly the
case of wind energy, until foreign investors decided to come to Brazil and “make it
happen”. The same applies to GEOTHERMAL ENERGY.
GEOTHERMAL energy potential knowledge relies mainly in data obtained in the late 70s
due to the first oil crisis of the early 70s. Nothing or very little has been made since then.
A few university groups make some research in this area, but they lack resources to make
it systematically up to the implementation of a large demonstration project.
So far no high enthalpy GEOTHERMAL resources have been detected in Brazil.
However, there are some potential for medium enthalpy resources that can generate
electric energy by means of binary systems. On the other hand the vast majority of all
detected resources and great part in use are low enthalpy.
Exploitation technology for GEOTHERMAL energy generation includes deep drilling
whose experience derives from Oil exploitation drilling. Therefore, oil companies are
potential partners in this venture, mainly considering obsolescence of oil as fuel in the
long time.
Geothermal drilling for energy generation depends on geothermal gradient. Brazil’s
average geothermal gradient is around 30o.C/Km. However, regional extremes may be
found between Oo.C and 45o.C/Km. Anomalous areas may present gradients as high as
90o.C/Km locally. If one consider conservatively an area of geothermal gradient of
45o.C/Km, it can be expected drillings down to 5Km deep to generate energy.
Presently, the only geothermal resources being exploited in Brazil are those so called
BRT, PIS and PBT. Nevertheless, exploitation areas need a better management of such
resources and promotion of such use where there is potential demand. Total installed
capacity in Brazil is 362MW. PIS represents 343MW, BRT equals 16MW and TDB only
3MW. Among these, there are 12 agricultural drying and industrial process heating
systems.
High enthalpy project areas in Brazil rest to be identified. On the other hand, so called
medium enthalpy resources have some potential already identified that expects for further
feasibility studies.
Total geothermal energy potential in Brazil has to be updated. Nevertheless, old
estimates, up to now still considered by the World Energy Council, mentions 3GW. The
most important is that great part of such potential is near the largest energy consumer
cities, areas and regions of the country.
4. A readily available, low cost, entrepreneurship promoter and low technology demander
way of using geothermal energy in the country is in the AIR CONDITIONING area.
Although in the case of Brazil most geothermal energy systems will be used for air
cooling, in the south region or mountainous areas, these may be used for heating.
Experience and skill is very well developed in this area, in United States. One may even
say there is a GEOTHERMAL AIR CONDITIONING SHOP in “every corner” of the
country. Equipment is simple, as well as its assembly. A heating pump that can be called
cooling pump in warmer regions, may be even bought cheaply through the World Wide
Web, even from China. Although installation costs may be a little higher (20%) when
compared to conventional air conditioning, low or absence of maintenance and, less
energy consumption (no need to consume energy for heating or cooling) may reduce
operational costs of GEOTHERMAL AIR CONDITIONING down to 50% or less of
conventional air conditioning or heating systems.
In economic terms, considering energy supply for electricity and heating, geothermal
energy in the world has shown to be the most economical option after biomass, in terms
of investments and energy supply, when compared to biomass, wind and solar energy.
For electric generation investment costs for turnkey plants are between US$800 and
US$3000 per KW. Meanwhile supply stands between 2 and 10 cents per Kwh, pointing to
1 to 10 cents per Kwh in the future. Another advantage when compared to other energy
sources is that availability of geothermal power plants are above 90%. When used for air
conditioning or heating, cost numbers are even lower, with plants in the range of US$200
and US$2000 per KW and consumption costs between 0,5 and 5 cents per Kwh.
Geothermal energy also surpasses most other forms of energy in use, when
environmental costs are considered. Studies in Australia have shown that emission
control costs per MWh are lower than for conventional fuel plants, wind power, solar
power and power from biomass. The same stands for the overall environmental impact of
geothermal energy.
Finally, only one question remains: What are you waiting for investing in geothermal
energy in Brazil?
