2008- Renewable Energy Grows!- Year in Review

Growing concerns over climate change and energy security have kicked research on alternative energy sources into high gear. The list of options continues to expand, yet few papers have comprehensively reviewed them. And fewer still have weighed the pros and cons in as much depth as a new study published earlier this month in the journal, Energy & Environmental Science. The results are a mixed bag of logical conclusions and startling wake-up calls. The review pits twelve combinations of electric power generation and vehicular motivation against each other. It is a battle royal of nine electric power sources, three vehicle technologies, and two liquid fuel sources. It rates each combination based on eleven categories. And it was all compiled by one man, Mark Jacobson, professor of civil and environmental engineering at Stanford University.

The US Department of Energy has released the latest edition of their Annual Energy Review (from the Executive Summary): The projections in AEO2009 look beyond current economic and financial woes and focus on factors that drive U.S. energy markets in the longer term. Key issues highlighted in the AEO2009 include higher but uncertain world oil prices, growing concern about greenhouse gas (GHG) emissions and its impacts on energy investment decisions, the increasing use of renewable fuels, the increasing production of unconventional natural gas, the shift in the transportation fleet to more efficient vehicles, and improved efficiency in end-use appliances. Using a reference case and a broad range of sensitivity cases, AEO2009 illustrates these key energy market trends and explores important areas of uncertainty in the U.S. energy economy. The AEO2009 cases, which were developed before enactment of the American Recovery and Reinvestment Act of 2009 (ARRA2009) in February 2009, reflect laws and policies in effect as of November 2008.

The government announced approval Friday of the first loan guarantee for an energy project under a program that Congress approved four years ago, only to see it hamstrung by years of delay. Energy Secretary Steven Chu vowed as one of his top priorities to revamp and speed up the loan guarantee program, promising to cut the time it takes to review applications, many of which have been on file at the department for a year or more. On Friday, Chu announced approval of a $535 million loan guarantee to Solyndra Inc., a company in Freemont, Calif., that makes solar panels for commercial buildings. The company said the government guarantee will cover debt financing for 73 percent of the cost of a second manufacturing plant in Freemont.

Technology Review has an article on a new system from Ener-G-Rotors which harvests energy from low temperature waste heat - Electricity from Waste Heat. Factories, data centers, power plants--even your clothes dryer--throw off waste heat that could be a useful source of energy. But most existing heat-harvesting technologies are efficient only at temperatures above 150 °C, and much waste heat just isn't that hot. Now Ener-G-Rotors, based in Schenectady, NY, is developing technology that can use heat between 65 and 150 °C.
