How much of our electricity is generated from renewable energy sources?

Slide show must be updated to August 2010.

Wind-generated electricity increased by 61% in 2007 and 2008 to 28% more than other new sources of generation, as well as in 2008 and 2009. these increases would above all newly built wind power plants.

Hydroelectric generation is increasing in and reduce the amounts to be paid in the other, as a matter of priority, and a large rainfall hydroelectric dams are located in the ' variation of snowfall aluerajat.

Renewable energy consumption increased by around 8% in 2008-2009, the Nation energy demand is about 8% and 10% of the total US electricity generation 1, 2009.

53% of the Electricity consumed producers2 Us renewable energy electricity. 3 2009 produce about 26% use of renewable energy sources was biomass consumed by industry (mainly paper-making) industrial applications involved in the use of tools, producing heat and steam.Biomass is also used in transport fuels (ethanol and biodiesel) to residential and space heating. in 2009 the highest proportion of renewable electricity generated by hydroelectric production counterfeits (66%), followed by the wind (17%), wood (9%), biomass waste (4%), geothermal (4%) and Sun (0.2%). 4 Wind-generated electricity rose by 28% in 2008 over 2009, more than any other energy source.

The consumption of renewable energy in China leads generation due to the recent massive additions to the world's hydroelectric production, will follow closely in the United States, Brazil and Canada, however, the United States consumes most. non-water for the production of electricity from renewable energy sources.The United States consumes twice as much water renewable energy sources for electricity production, Germany and more than three times as much as 5 Spain.

The u.s. Energy Information Administration (EIA) projects, which take into account the use of renewable electricity generated by 17% of total US electricity production up 9% to 2035, 2008, this growth is mainly active in the extension of federal tax credits and the new loan in order to ensure the program at the part-session in February 2009 American recovery and Reinvestment Act (ARRA).

From the point of view of the global assessment of the environmental effects of projects that renewable energy is the fastest growing source of electricity generation, a large increase in the forecast period are expected to be hydroelectric power and wind power through 2035.7.

Most renewable energy power plants have less environmental impact than the fossil and nuclear power plants, but there are two main reasons why we use do not include renewable energy sources.

  Renewable energy Technologies are Capital-Intensive:Renewable energy power plants are usually more expensive than the work than coal, and natural gas plants.However, in recent years, some of the wind speed for producing multiple images of the plants have been shown to be economically feasible in areas with good wind resources, compared to other traditional technologies, when combined with the use of renewable sources of electricity production tax credit (described below).Renewable resources are often geographically Remote:Most renewable resources are only available in remote areas, often, so the power transmission power supply large metropolitan areas to be expensive.

There are three types of policies with a view to increasing the use of renewable energy sources are:

VAT credits:Renewable energy sources for electricity production tax credit, the Federal incentive has encouraged the wind-energy capacity of eight fold increase since 2001. EIA forecasts assume that tax credits expire in accordance with the laws in force in the EIA analyses show that the extension of the tax credits would other generation resources.Objectives:Many are renewable Portfolio Standards (RPS) that require to produce or acquire a percentage of electricity generation from renewable energy sources. 8, however, providers, many of the RPS programs is the "escape clauses" If the cost of renewable generation. starting from a threshold equal to or is delayed in some countries, in compliance with and enforcement procedures and other missing. therefore, in some States may meet the objectives of the RPS. EIA projected that, ultimately, most of the Member States should respond to the requirements of the RPS. 9 markets: States is built into Renewable Energy certificates (RECs)/Credits of their renewable energy Portfolio Standards 10 this provides electricity providers sell renewable energy certificates/credits and use their return on new projects. some States require REC is the market shall be the subject of electricity providers produce or acquire new generation, reduction of dependence on fossil fuels for electricity.
