Renewable Energy


Climate concerns and dwindling fossil fuel resources are driving an increasing demand for renewable energy solutions. Many countries have passed legislation to increase the use of renewable energy sources and this has, in turn, created a market for new technologies in the area.

Safe and Secure
Energy sources that are perpetual, or self-renewing, guarantee a secure supply, thus minimizing dependency on outside energy suppliers. At the same time, use of renewable energy cuts emissions of carbon dioxide, thereby addressing environmental concerns.

In Denmark renewable energy currently accounts for 15.5% of the country’s gross energy consumption – and more than 27% of all generated electricity. The Danish government has initiated a program to ensure that by 2025 30% of total energy consumption will be from renewable energy sources.

Green Power

Green power is electricity that is generated from resources such as solar, wind, geothermal, biomass, and low-impact hydro facilities. Conventional electricity generation, based on the combustion of fossil fuels, is the nation's single largest industrial source of air pollution. The increasing availability of green power enables electricity customers to accelerate installation of renewable energy technologies. As more green power sources are developed - displacing conventional generation - the overall environmental impacts associated with electricity generation will be significantly reduced. 


Benefits of Green Power
Choosing green power offers a number of benefits to businesses and institutions, including:
     Environmental stewardship - Many innovative organizations are establishing environmental commitments to make their operations and practices sustainable. Choosing green power is a simple step towards creating a more sustainable organization.
     Public image - Green power can help improve an organization's public image by demonstrating environmental stewardship.
     Customer loyalty - Demonstrating environmental stewardship through green power may help increase an organization's customer and investor loyalty.
     Employee pride - Employees prefer to work for companies that give back to their communities and to the environment.
     Power portfolio management - Because some green power sources have no fuel costs, green power can help protect your power portfolio from volatile prices of fossil-fuel-generated electricity.
     Power reliability - On-site renewable generation can be a more reliable source of power than power distributed through the electric grid.

Green Power Options
Green power is available in four basic forms, the availability of which partially depends upon the status of electric utility restructuring in the state where the purchase is being made.
     Blended products
     Block products
     Green tags or renewable energy certificates
     On-site renewable generation

Blended Products
Also known as "percentage products," blended products allow customers, primarily in states with competitive electricity markets, to switch to electricity that contains a percentage of renewable energy. The renewable energy content of blended products can vary from 2 percent to 100 percent according to the renewable resources available to utilities or marketers. 


Block Products
Block products allow customers served by monopoly utilities to choose green power from the electric grid in standard units of energy at a fixed price, which is converted to a premium and added to their regular electric bill. Customers decide how many blocks they want to purchase each month. 


Green Tags or Renewable Energy Certificates
Green tags allow customers to purchase the renewable attributes of a specific quantity of renewable energy. Green tags are sold separately from electricity and can be purchased for a location anywhere in the U.S. In this way, a customer can choose green power even if the local utility or marketer does not offer a green power product. One green tag typically represents the renewable attributes associated with one megawatt hour of green power. 


On-Site Renewable Generation
Customers can install their own renewable energy generating equipment at their facility. On-site renewable generation can increase power reliability, provide stable electricity costs, and help manage waste streams. Furthermore, in many states, excess green power generated on-site can be returned to the electric grid, in effect allowing customers to obtain credit from their utility. (This is also known as "net-metering.")


Certification and Accreditation
Green power certification and accreditation programs help ensure that customers get what they pay for when they choose green power.

     Green-e is a voluntary certification and verification program for green power products developed by the non-profit Center for Resource Solutions.

     The Green Pricing Accreditation Initiative, developed by the Center for Resource Solutions, accredits green pricing programs operated by regulated electric utilities.

Energy and Information Society
Modern society continues to rely largely on fossil fuels to preserve economic growth and today's standard of living. However, for the first time, physical limits of the Earth are met in our encounter with finite resources of oil and natural gas and its impact of greenhouse gas emissions onto the global climate. Never before has accurate accounting of our energy dependency been more pertinent to developing public policies for a sustainable development of our society, both in the industrial world and the emerging economies. At present, much emphasis is put on the introduction of a worldwide cap-and-trade system, to limit global emissions in greenhouse gases by balancing regional differences on a financial basis. In the near future, society may be permeated at all levels with information systems for direct feedback on energy usage, as fossil fuels continue to be used privately and for manufacturing and transportation services. Information in today's society, focused on knowledge, news and entertainment, is expected to extend to energy usage in real-time. A collective medium for energy information may arise, serving to balance our individual and global energy dependence on fossil fuels. Yet, this development is not without restrictions, notably privacy issues. Recently, the Dutch Senate rejected a proposed law for mandatory national introduction of smart metering, in part, on the basis of privacy concerns

We are trying to develop awareness among our customers and people to save both water and energy and  help us contribute our share in the governments efforts  in this regards.

 

On realizing that  fuels consumed to generate energy for doing different works are contributing carbon dioxide increase of the atmophere. Thus using our energy wisely has now become real importance of our world. Every effort should be made to employ any energy  saving tip practical and explore these ideas to the other parts of the globe.

We  have now entered into a globalization phase and every indivisuals action is effecting the remaining world .

For some people working on this two side sword may  not be a practical issue as the second thing definitely will reduce the use of the water purification & energy  generation systems which is against the marketing principal (develop and explore areas for new business development)  

Theu use of these fossile materials is causing huge increase in the carbon dioxide of the atmosphere which  results in increase of our atomospheres temperature. This is causing increase in our world temperature is melting glaciers and polar ice,  raising the sea levels and causing a no of various changes in the world weather and climate conditions.

As the energy demand is increasing day by day,  efforts are put behind making use of new non-fossil fuels. There is huge room for the development of new techniques as

The age of alternative energy is dawning upon us. Wind power, geothermal energy, solar energy,

hydropower, nuclear power, fuel cells and bioenergy -all of them come with their own set of

developmental challenges, implications and opportunities. Understanding these issues will allow us an

insight into a world where alternative energy is no longer the alternative but the only solution to a

sustainable world.


Nonrenewable Energy
We get most of our energy from nonrenewable energy sources, which include the fossil fuels — oil, natural gas, and coal. They're called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth's core and pressure from rock and soil on the remains (or "fossils") of dead plants and creatures like microscopic diatoms. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.
We use renewable and nonrenewable energy sources to generate the electricity we need for our homes, businesses, schools, and factories. Electricity "energizes" our computers, lights, refrigerators, washing machines, and air conditioners, to name only a few uses.
Most of the gasoline used in our cars and motorcycles and the diesel fuel used in our trucks are made from petroleum oil, a nonrenewable resource. Natural gas, used to heat homes, dry clothes, and cook food, is nonrenewable. The propane that fuels our outdoor grills made from oil and natural gas, both nonrenewable.
The chart above shows what energy sources the United States uses. Nonrenewable energy sources account for 93% of all energy used in the Nation. Biomass, the largest renewable source, accounts for over half of of all renewable energy and 3.7% of total energy consumption. (Note: 53% of 7% is 3.7%.)
US energy department website

Energy sources are divided into two groups — renewable (an energy source that can be easily replenished) and nonrenewable (an energy source that we are using up and cannot recreate). Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen.
Renewable Energy


Renewable energy sources include:

•    Solar energy from the sun, which can be turned into electricity and heat
•    Wind
•    Geothermal energy from heat inside the Earth
•    Biomass from plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil
•    Hydropower from hydroturbines at a dam


Currently, traditional fossil fuel power generation is responsible for over 85% of our energy. Renewable energy sources constitute a very small fraction, only 2%, of our total global power generation. The forecast at best is unpredictable markets as fuel supply constraints and carbon regulation continues to create unpredictable markets due to volatility in energy costs and fossil fuel prices. Our focus and future must be on renewable energy.

How much energy do we use?
See the Statistical Review of World Energy 2005 by British Petroleum. Here is the powerpoint presentation (2.6 MB). 


1.    Global energy use in 2003 was 4.1 X 1020 Joules which is equivalent to 13 Terawatts.

a.    1 Terawatt (TW) = 1012 Joules/second= 1012 Watts.

b.    The global energy use is equivalent to 71,000,000,000 barrels of oil equivalent used at the rate of 196,000,000 barrels of oil equivalent per day or the energy in 4.6 metric tons of mass converted into energy.

2.    Global energy use from fossil fuels was approximately 8,260 million metric tons oil equivalent, which is approximately 9,623 X 106 m3 = a cube of oil 2.12 km on a side.
3.    Global oil consumption in 2003 was 76,800,000 barrels of oil per day.

a.    Most of the remainder of our energy comes from natural gas and coal.

b.    All are fossil fuels.

4.    The per capita consumption of energy in the United States is about 57 barrels of oil equivalent per year or 11 kW continuously.

a.    The energy is used to heat and light homes, offices, and stores, to power trucks and automobiles, and to operate machinery.

b.    57 barrels of oil at $50/barrel = $2,850.

c.    If the energy were used entirely as electricity, it would cost about $7,300 per person per year.

5.    Consumption of energy in the United States was approximately:

a.    39.1% oil

b.    25.9% natural gas

c.    24.4% coal

d.    8.1% nuclear energy

e.    2.5% hydroelectric, or

f.    89.4% from fossil fuel consumption.

The United States used approximately 24% of all the world's energy, although we are only 4.6% of the world's population.


Alternative Sources of Energy
To avoid the high cost of oil, and to reduce the emissions of greenhouse gases, governments are seeking alternate sources of energy. In the short term the outlook is bleak. Hoffert et al (2002) summarized the possibility of replacing fossil fuels with alternative sources of energy. Here is part of their abstract.
Here we survey possible future energy sources, evaluated for their capability to supply massive amounts of carbon emission-free energy and for their potential for large-scale commercialization. Possible candidates for primary energy sources include terrestrial solar and wind energy, solar power satellites, biomass, nuclear fission, nuclear fusion, fission-fusion hybrids, and fossil fuels from which carbon has been sequestered. Non-primary power technologies that could contribute to climate stabilization include efficiency improvements, hydrogen production, storage and transport, superconducting global electric grids, and geoengineering. All of these approaches currently have severe deficiencies that limit their ability to stabilize global climate. We conclude that a broad range of intensive research and development is urgently needed to produce technological options that can allow both climate stabilization and economic development.
From Hoffert (2002).
The important points made in the article are:

1.    "Energy sources that can produce 100 to 300% of present world power consumption without greenhouse emissions do not exist operationally or as pilot plants."
2.    Improved efficiency in use of fuels is possible, although many uses are already very efficient.
3.    "10 TW from biomass requires >10% of Earth's land surface, comparable to all of human agriculture." And, we are now using 12 TW, and we will use around 30 TW by mid century. Already, by 2008 the demand for biofuels collided with the demand for more and better food in developing countries leading to soaring food prices and food riots in many countries.
4.    "The electrical equivalent of 10 TW requires a surface array [of photocells] ~470 km on a side (220,000 km2). However, all the PV cells shipped from 1982 to 1998 would only cover ~3 km2"
5.    "The main problem with fission for climate stabilization is fuel...Current estimates of U in proven reserves and (ultimately recoverable) resources are 3.4 and 17 million metric tons, respectively ...At 10 TW, this would only last 6 to 30 years--hardly a basis for energy policy.

A second article by Pacala and Socolow (2004) noted "A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO2 to a trajectory that avoids a doubling of the preindustrial concentration..." Here is the abstract of their paper. 


Humanity already possesses the fundamental scientific, technical, and industrial know-how to solve the carbon and climate problem for the next half-century. A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO2 to a trajectory that avoids a doubling of the preindustrial concentration. Every element in this portfolio has passed beyond the laboratory bench and demonstration project; many are already implemented somewhere at full industrial scale. Although no element is a credible candidate for doing the entire job (or even half the job) by itself, the portfolio as a whole is large enough that not every element has to be used.
From Pacala and Socolow (2004).


Still, even this will not be easy:
To put the stabilization challenge in stark terms, under Pacala and Socolow's most optimistic assumptions for stabilization at 550 p.p.m., the world will need to reduce its projected business-as-usual emissions by about 1,000 gigatonnes of carbon over the next century. Seven stabilization wedges worth would achieve 175 gigatonnes, leaving a considerable gap, even if the total business-as-usual emissions have been overestimated by a factor of two or more.
Many believe that if climate change can be dealt with relatively easily, then there would also be little need to adapt to it. This sort of thinking may explain why the issue of adaptation plays no role in the book. Overlooking adaptation in any discussion of climate policy is a sign that the challenge posed by climate change has been fundamentally mischaracterized — not only because the world is already committed to some degree of climate change, but also because adaptation makes sense under any future climate scenario.
From Pielke (2006).
In the words of Hardin in The Tragedy of the Commons, we must change our behavior to solve this problem,
One alternate source of energy that may be must useful for the next few decades may be nuclear fission, used by nuclear power plants. All power sources contribute to greenhouse gases, either directly through burning of fossil fuels, or indirectly through construction of facilities. But nuclear, wind, and hydro power contribute least.
The cost of producing energy from alternative sources varies greatly, Nuclear energy is slightly more expensive than wind, geothermal, and biomass.



 
Price of energy from alternative sources compared with cost from fossil fuels.
From Forbes Magazine (24 November 2008: page 64).
We can reduce present fuel use by using more efficient systems such as mass transportation. But consider this editorial:
There are just two problems with mass transit [in the US in 2005]. Nobody uses it, and it costs like hell. Only 4% of Americans take public transportation to work. Even in cities they don't do it. Less than 25% of commuters in the New York metropolitan area use public transportation. Elsewhere it's far less -- 9.5% in San Francisco-Oakland-San Jose, 1.8% in Dallas-Fort Worth. As for total travel in urban parts of America -- all the comings and goings for work, school, shopping, etc. -- 1.7 % of those trips are made on mass transit. ... Heritage cites the Minneapolis "Hiawatha" light rail line, soon to be completed with $107 million from the transportation bill. Heritage estimates that the total expense for each ride on the Hiawatha will be $19. Commuting to work will cost $8,550 a year. If the commuter is earning minimum wage, this leaves about $1,000 a year for food, shelter and clothing. Or, if the city picks up the tab, it could have leased a BMW X-5 SUV for the commuter at about the same price. We don't want minimum-wage workers driving BMW X-5s. That's unfair. They're already poor, and now they're enemies of the environment?
From: O'Rourke (2005).
Historical experience since 1800 shows that increased energy efficiency usually leads to more energy consumption. Clearly, we have a long way to go to solve the problem of too many people driving cars.
Survey of Energy Resources 2007
Overview

“Energy is essential for development, yet two billion people currently go without, condemning them to remain in the poverty trap. We need to make clean energy supplies accessible and affordable. We need to increase the use of renewable energy sources and improve energy efficiency. And we must not flinch from addressing the issue of over consumption - the fact that people in the developed countries use far more energy per capita than those in the developing world” (Kofi Annan,  Secretary General, United Nations.)


Introduction
The availability of energy resources is of paramount importance to society. This new World Energy Council Survey of Energy Resources addresses the question of future availability at a critical time in the development of global economies and the people who depend on them. The fundamental dilemma facing us is that energy is a vital ingredient for growth and sustainable development, and for the vast majority of economic activities, but that energy production and use contribute to global warming. The greatest challenge facing the energy sector today is how to meet rising demand for energy, whilst at the same time reducing our emissions of greenhouse gases. Climate change is undoubtedly an imperative which must be addressed with a sense of urgency. We need to find new and innovative ways of addressing mitigation of greenhouse gases as well as adapting to changes in the climate. Given that the energy sector is critical to the functioning of  most economies, is long term in nature and is very vulnerable to the negative impacts of climate change, this issue should be at the top of everyone’s agenda.
Resources are the backbone of every economy. In using resources and transforming them, capital stocks are built up which add to the wealth of present and future generations. However, the dimensions of our current resource use are such that the chances of future generations having access to their fair share of scarce resources are endangered. We therefore need to ensure the sustainable use of our natural resources through the creation of a longterm sustainable base and much greater focus throughout the energy value chain.
Access to energy and security of supply Lack of access to energy hampers economic and social development in many regions and is an obstacle to the achievement of social, environmental and economic progress worldwide. Access to reliable, affordable commercial energy provides the basis for heat, light, mobility, communications and agricultural and industrial capacity in modern society. Energy is important for development as is demonstrated in consumption trends – notably, the increase foreseen in energy demand, for example the International Energy Agency estimates an increase of 60% by 2030, (World Energy Outlook, 2002). This increasing demand will have to be met by a complex mix of energy resources in order to meet a wide variety of energy needs, whilst considering environmental  and other constraints. Meeting society’s needs, aspirations and expectations for a better life will require growing supplies of reliable, affordable and lower-carbon energy.


Multi-Energy Systems
We need to continue to keep all energy options open and to develop, as appropriate, all primary energy supplies. Keeping all energy options available will enable every nation to tailor its approach to addressing energy needs and climate change in the most efficient way, in alignment with their respective resource base and long-term strategic development objectives. One critical tool in the arsenal is energy efficiency, as it is a critical component of any comprehensive sustainable energy strategy and can make a significant and short-term impact on emissions of greenhouse gases. Energy efficiency needs to be promoted among producers and consumers of energy through the establishment of appropriate fiscal and regulatory  frameworks. However more action is needed to turn ideas into action. Globally everyone needs to identify opportunities to reduce their consumption of energy and improve efficiency. Many countries and companies are doing exactly that – and some will be left behind if they do not also rise to the occasion.
At the same time it does not help to address only one element of the energy sector. Energy supply and use pose political and economic issues related to economic growth, security, employment, investment, climate change, environmental impacts and trade. Consequently, energy challenges should be addressed through integrated policies reflecting a broad range of issues including development priorities and needs; social conditions and aspirations; trade rules; environmental policies; and the promotion of innovation, together with technology development and transfer policies and energy efficiency. Climate change is a multifaceted and broad-based issue and thus it is particularly important that climate change issues are integrated into all relevant policies.


The long road ahead


Let us not fail to fully understand the magnitude of the challenge facing us. The challenge that we face is bigger than one country or company and the evolution of energy systems will require considerable time and expense in order to alter energy and raw material inputs, operations and products and to develop and introduce technological innovations, as well as to establish the infrastructure to support them. Companies and governments should take these long-term considerations and realities into account, and strive for consistency and predictability over the corresponding time span.
Maintaining and growing the energy supplies required to provide access to those lacking it and to meet future demand with reduced environmental impacts will require significant investment in the long term in every element of the supply and use chain. This investment is estimated by the IEA to be US$ 20 trillion by 2030.  Mobilising the required energy investments will be a key  challenge. In countries with limited capital, and specifically for the least developed countries, the role of Foreign Direct Investment should be complemented by Inter-Governmental Organisation funds, Official Development Assistance (ODA), and local private funds. Through such innovative financing solutions, project creation and implementation benefit from a variety of sources of funds, which are mutually reinforcing, each fund being  adapted to the type of investment and risks it covers.
The challenge of climate change adds an additional dimension to this issue and historical paradigms of investment in infrastructure must be challenged if we are to meet the challenges of ridding the world of energy starvation through a cleaner and lower carbon-emitting path. In adopting a holistic approach to this value chain there is a significant opportunity for the public and private sector to work together to build lower carbon-emitting energy infrastructure and then use it for economic, social and environmental development. The challenge of climate change adds an additional dimension to this issue and historical paradigms of investment in infrastructure must be challenged if we are to meet the challenges of ridding the world of energy starvation through a cleaner and lower carbon-emitting path. In adopting a holistic approach to this value chain there is a significant opportunity for the public and private sector to work together to build lower carbon-emitting energy infrastructure and then use it for economic, social and environmental development.
Energy for sustainable development will depend on the more widespread use of existing efficient technologies as well as the development, commercialisation and deployment of innovative and lower-carbon technologies. To expand and take advantage of the full potential of energy options, all relevant stakeholders should allocate resources to research and development of new technologies all along the energy chain. The energy sector dedicates substantial resources to
technology advancement and the development of innovation but we also need to be a partner in  defining mechanisms to identify, develop, commercialise and transfer technologies on a global scale. In order to accelerate the development and deployment of technologies, large demonstration or pilot activities should be considered in order to develop capacity and to increase the rate of uptake of key technologies. While fossil fuels will continue to play an important role in energy supply in the decades to come, every effort must be made to diversify the energy mix. Urgent action is required to further diversify energy supply by developing advanced, cleaner, more efficient, affordable and costeffective energy technologies such as renewables (including large-scale hydropower) and nuclear power. In addition, quantum leaps need to be made in the implementation of energy efficiency measures. Further, in areas were water is scarce, the application of technologies such as dry cooling, needs to be employed. The publication of the data in this report can provide the foundation for sustainable energy planning as we move forward.
This transformation, as well as meeting the need for skills to build and operate plant is critical. Education is essential to supporting research and facilitating efficient deployment and operation of energy technologies. Furthermore, education is important for helping users to make informed energy choices.
Conclusion
We know that the energy sector is a major contributor to global greenhouse gas emissions and in order to meet the challenges of meeting  the rising demand for energy whilst reducing greenhouse gas emissions and adapting to the impacts of a changing climate, global efforts will be required. This has been the subject of the recently released WEC report on Energy and Climate Change. The efforts in this area require
concerted action which replicates successes around the world and through public-private partnerships which leverage resources and channel international effort. The energy sector
will not only be a key implementer of global policy, but will also contribute through innovation and the development and deployment of new technologies. It is recognised that there is no
technological “silver bullet” but that all technologies are important to assess, including renewables and clean-coal technologies. In addition, technologies that result in significant
cuts in greenhouse gases, such as nuclear power, have a crucial role to play. Carbon markets also have an important role to play and should be encouraged and normalised as far as
possible.
In conclusion, I am a firm believer in the words of an eighteenth century British MP Edmund Burke, who said “Nobody made a greater mistake than he who did nothing because he could only do a little”. We all play a vital role in contributing towards global imperatives and we need to define novel ways in which to leverage resources in meeting the challenges we collectively face.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups — renewable (an energy source that can be replenished in a short period of time) and nonrenewable (an energy source that we are using up and cannot recreate in a short period of time). Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen.
Renewable energy sources include solar energy, which comes from the sun and can be turned into electricity and heat. Wind, geothermal energy from inside the earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.However, we get most of our energy from nonrenewable energy sources, which include the fossil...
