Latest EIA Report Shows Renewable Energy Production Continues Growth in 2010, Equals Nuclear Energy Output


Wind energy saw the largest growth in 2010The latest Monthly Energy Review released by the U.S. Energy Information Administration (EIA) last week shows both nuclear and renewable energy sources provided roughly 11 percent each of primary energy production for the first nine months of 2010 – the latest period for which data is available.

The EIA report states that renewable energy sources, including biomass/biofuels, solar, wind, hydro, and geothermal contributed 10.9 percent of domestic energy production through the end of September, up 5.7 percent over the same period in 2009. Nuclear energy accounted for 11.4 percent of domestic production – down 0.5 percent from the same period last year.

Renewable energy statistics breakdown

Of the various sources of renewable energy, each contributed the following to the overall renewable portfolio:

  • Biomass/biofuel: 51.95 percent
  • Hydropower: 31.50 percent
  • Wind: 10.52 percent
  • Geothermal: 4.65 percent
  • Solar: 1.38 percent

Wind, biofuels shows biggest growth

Comparing those statistics with the same period of 2009 shows solar energy production expanding 2.4 percent and hydro declining by 5.2 percent. The big winners were biomass and biofuels, which grew by 10 percent in the first three quarters of 2010, and wind energy, which grew a full 26.7 percent. Combined non-hydro renewable sources grew 11.5 percent.

Overall, U.S. primary energy production rose 2 percent in the first nine months of 2010 over the same period last year. Fossil fuels accounted for 78 percent of primary energy production.

“Members of the incoming Congress are proposing to slash cost-effective funding for rapidly expanding renewable energy technologies while foolishly plowing ever-more federal dollars into the nuclear power black hole,” said Ken Bossong, Executive Director of the SUN DAY Campaign. “The numbers clearly show this would be betting on the obvious loser while ignoring the clearly emerging winner in the energy race.”

Global Warming, Wind Energy and the Turbine

Summer N Banks asked:

The greatest concern that plagues any nation today is the issue of Global warming. Pollution has led to environmental degradation causing widespread climatic changes and also resulting in various health hazards. It is not only the various governments of the different countries but also the business houses and the companies who are spending time and money to bring about radical changes in development of sustainable, renewable and alternative sources of energy. It is here, that the power generated from wind energy has emerged as one of the fastest growing renewable energy technologies. Wind power energy is one of the most viable options amongst the various renewable energy technologies today.

Wind energy technologies have matured over the years and the usages of wind turbines for power generation have gained momentum. The latest are the vertical axis wind turbines that need to be pointed towards the direction of the wind in the homes that will result in generating the cleanest energy. The kinetic energy of the wind is transformed into mechanical energy by these specially designed wind turbines. Most wind turbines have start up speed of 8 MPH but it requires a minimum average speed of 12 MPH. The height at which the wind turbines work best is approximately 100 feet. Another important thing is it requires half an acre of land to make it efficient without many obstructions. There exist three types of wind turbines especially designed for the residential owners.

Wind power generators are again one of the most reliable sources of green power on the planet. The concept of wind farms is also gaining in popularity. Wind farms install many turbines, scattered over a larger area thereby harnessing the wind energy to its maximum capacity. It is said that the largest wind farm is in Texas known as the Horse Hollow Wind Energy Center has about 421 wind turbines that can generate electricity to power approximately 230,000 homes per year.

In recent times, there are companies that are specializing in providing information on wind “resources” around the world. This is before erecting any wind turbine, the area should be properly chosen, and the companies in this respect can provide data on wind that is blowing 80 m high over an area of 15 km for a year. This detailed information in turn would open up vast areas for the development of this renewable and clean source of energy.

To leap forward over fossil fuels, it is imperative that we spend more time and research on developing this most economical renewable source of energy.
