When the APS Forum on Physics and Society publication "Physics and Society" published an article by one Wallace M. Manheimer suggesting with little evidence that renewable energy was useless, I felt obligated to respond with some more complete information. They published my letter in the latest issue; I've reprinted it below.
Wallace M. Manheimer's article  on energy choices in the April 2012 issue makes a number of important points, but also goes wrong on many fronts, and I hope Physics & Society will allow at least some correction of these misstatements.
To start at the end, Manheimer asserts that "one cannot talk about climate and ignore energy supply. Yet, these organizations [AIP and APS] have done just that." One need only read the same issue of Physics and Society to know that claim is false - the book review by Paul P. Craig  mentions "the first APS energy study [...] in 1973", which has been followed by many others. Manheimer himself cites the recent APS "Energy Efficiency Report" - and then appears to dismiss it as parochial. This is ironic since he earlier claims that cutting US energy use would be "worse because distances are much greater in the United States, it is colder here, and we have responsibilities as a major world power" Manheimer's argument pertains to Italy, but in general technology developments allowing efficiency gains in the US apply equally well or better elsewhere.
In testimony to congress this past week, new energy secretary Steven Chu made the case for the administration's energy plans which include considerable increases in spending in a number of areas, and several new programs. Among the things they appear to be really trying to push is getting ARPA-E off the ground - there's $415 million allocated, but apparently a lot of resistance within the department to actually making it happen. In a companion handout for the hearing, the case for and priority areas for ARPA-E were highlighted. The handout perhaps explains why DOE bureaucrats may be resisting:
