The phrase Green Energy or renewable energy is used to illustrate the different causes of energy which do not pollute the environment and are eco friendly. This sort of energy is usually considered in the situation of cogeneration, electricity and heating and is becoming more usable by consumers, corporations and businesses which support the development and decrease the impacts of environment which is linked with the usual generation of electricity and enhance the energy independence of a certain nation. Over 1 million homes in US and around 35 million in the whole of Europe are purchasing certain certificate like green tags and green certificates which are renewable certificates of energy to support the green energy. (Flavin, Christopher, 167)
The benefits of Green Energy
The full spectrum of renewable technologies–solar, wind, hydroelectric, and biomass–holds unique potential for providing clean, reliable, and affordable energy in the long term. Solar and wind resources are replenished on a daily basis. Biomass can be grown through managed agricultural programs to provide continuous sources of fuel. Hydropower, as part of total water management systems, is already an essential component in the global electricity supply, representing about 18 percent, whereas nonhydro renewables currently represent less than 2 percent.
Most renewable energy technologies do not need to be built on a large scale to achieve competitive plant costs. They can be installed in sizes suitable to load growth patterns and local needs, or they can be located closer to loads, reducing infrastructure costs for transmission and distribution. The output of solar technologies is strongly connected with load demand for example, for air conditioning in hot climates. This fact increases the value of locally installed solar photovoltaic relative to remote, fuel- based central power stations. In addition to hydroelectric sources, several renewable technologies central-station solar, wind, and biomass are expected to play an increasing role in grid backbone applications. Renewable energy technologies are critical for a transition to a hydrogen- based energy system. Today, nonhydro renewables are the fastest growing section of the supply market. In some regions, annual growth rates exceed 100 percent. (Ottinger, Richard L. 331)
Energy-Efficient Technology Essay
Energy-Efficient Technology Essay "America's swelling thirst for oil is one of our leading economic and national security problems. We use a quarter of the world's petroleum, but have just three percent of known reserves. As a result, we're importing more than half the oil we use each day from some of the most unstable regions of the world- spending more than $20 billion each year on Persian Gulf ...
Articulating the vision
One serious effort at discriminating the future of renewables is provided in Greenhouse Gas Reduction with Renewables, a December 2000 report by the Electric Power Research Institute (EPRI).
Excluding the electricity generated by usual hydroelectric dams but including electricity from emerging small-scale hydro for example, tidal and wave power, the EPRI analysis offers a set of scenarios in which the worldwide substitution of renewables for traditional sources in 2050 ranges from a low of 13 percent to a high of 29 percent. By 2020, when the start of major deployment of nonhydro renewables may be well under way, the level of infiltration of the electricity market could range from 6 to 14 percent.
In the twenty-first century, traditional biomass methods, alternatives of burning plant matter to produce heat used in generating electricity will become obsolete. They will be challenged and displaced over time by more cost effective and efficient technologies using either biomass or other energy sources. A new biomass energy technology, gasification, converts diverse forms of plant matter into a valuable, versatile synthetic gas (syngas) that may be used either as a fuel for producing electricity in fuel cells or turbines or as a feedstock for producing other fuels (hydrogen or transportation fuels).
The Essay on Technology in the Next 100 Years the Futurologist’s View
Futurologist Ian Pearson discussed technologies of the future to more than 200 IT, security and finance delegates on the Aurora cruise ship. He spoke of IT security threats from smart bacteria, gadgets which are installed in the skin, the soaring of tax rates precipitating the emigration of graduates to low-tax economies, oil at 30 dollars a barrel, and the reversal of globalization. Gadgets of ...
Biomass gasification holds particular promise in rural settings as a way of transforming agricultural and other wastes from pollutants into valuable energy resources. (Elliott, David, 20-22)
Mapping our energy future
Beginning in 1997, EPRI has conducted a series of meetings, workshops, and seminars that have included over 200 stakeholders from business, government, and public interest groups. The purpose of this ongoing process is to produce and continually refine an Electricity Technology Roadmap, intended to forecast likely developments in the economy and society over the next 25 years and how they are likely to interact with electricity and electricity- related science and technology. During these sessions, a vision of the future including global sustainability and economic success was formulated, and harmony began to emerge around some specific destinations that will help achieve this vision. These destinations comprise social and economic benefits that can be realized, as well as the challenges that must be successfully addressed through an integrated and focused program of scientific and technical progress in order to achieve the vision of the future.
While all these advancements need to be followed aggressively, there is also a need for patience. It takes time and money to research, develop, and then commercialize new technologies and concepts. As one example, the Arizona Public Service Company (APS) is planning the world’s largest high- concentration solar photovoltaic (HCPV) project, using commercially available technology that evolved from R and D supported in large part by EPRI during the late 1980s and ’90s. APS plans to install 500 kilowatts of 25-kilowatt sun-tracking HCPV arrays at multiple sites in Arizona this year. APS and Amonix Incorporated of Torrance, California (which developed the high-efficiency, potentially low-cost, utility-grade photovoltaic-generating technology), announced the plans in April 2000. Achieving the promises of renewable energy will require vision, dedication, and persistence on the part of many, but it would be well worth the effort (African Review of Business and Technology, 52)

The Term Paper on Impact Of Wind Energy On A Sustainable World
Is wind power green? Wind power, considered a ‘green energy’, has generally less negative effects on the environment; however, various implementations can have devastating ecological impact and ought to be avoided. Only with a realistic and critical analysis can we compare wind power to other sources. II. Wind power compared to other sources of power (Independent of environmental ...
