The IAEA has revised upwards its nuclear power generation projections to 2030, while at the same time it reported that nuclear´s share of global electricity generation dropped another percentage point in 2007 to 14%. This compares to the nearly steady share of 16% to 17% that nuclear power maintained for almost two decades, from 1986 through 2005.
Everyone contributes to carbon dioxide emissions, but some more than others. Reducing global CO2 emissions requires that we have a good understanding of the current picture. Serious progress can be made if we develop a renewable source of electricity that is cheaper than coal.
Improvements in energy efficiency over the past three decades have played a key role in limiting global increases in energy use and CO2 emissions. For IEA countries, energy efficiency gains since 1990 have led to annual energy savings of more than 16 EJ in 2005 and 1.3 Gt of avoided CO2 emissions. However, the recent rate of efficiency improvement has been much lower than in the past. The good news is that a large potential remains for further energy and CO2 savings across all sectors. In industry alone, the application of proven technologies and best practices on a global scale could save between 1.9 Gt and 3.2 Gt of CO2 emissions per year. In public power generation, if all countries produced electricity at current best practice levels, CO2 savings would be between 1.8 Gt and 2.5 Gt.
MIT Energy Club has put together this fact sheet on US electricity production and consumption that is quite handy. I share it here for the Energy buffs….
Renewable energy in the United States is on the rise. America now generates twice as much electricity from the wind and the sun as we did just four years ago, and 2007 promises to be another year of record growth.
Framing the issue as a struggle between those who favor the environment vs. the forces of "big business" is not only a bogus cliche. It's a dangerous trivialization of a serious problem.
This report presents the results of the eleventh international survey. It provides an overview of PV power systems applications and markets in the reporting countries at the end of 2006 and analyzes trends in the implementation of PV power systems between 1992 and 2006.
Surf this: The potential market for wave energy -- electricity generated by offshore turbines -- is worth a staggering $1 trillion worldwide, according to the World Energy Council, a nonprofit research organization. In the United States alone, wave technology could supply 6.5 percent of the nation's energy. No wonder, then, that startups are rushing to stake claims before someone else drops in on the best waves.
According to a new report from NanoMarkets LC the global market for thin-film photovoltaics (TFPV) is forecast to reach $7.2 billion by 2015, compared to just over $1.0 billion today.
