The answers my friend, are underfunded

Geothermal and wind energy are here and now -- ready to compete with fossil fuels in prime time. Moreover, modest funding could result in significant improvements in performance. Unfortunately federal research and development funding for these renewable energy technologies is woefully inadequate.

I'm hopeful that President Obama and Energy Secretary Steven Chu will federal R&D funding will reflect this Administration's commitment to a clean energy economy. (GW)

Wind, Geothermal Are Most Efficient Renewable Energy Sources - Study

Sustainable Business News
July 17, 2009

As the U.S. Congress debates an energy and climate bill, government organizations and corporations are assessing renewable energy alternatives. Which are the most efficient and improving the fastest? According to a new study from NYU's Stern school of Business, geothermal and wind energy are more efficient, and are yielding greater returns on the R&D invested in them, than most other renewable energy alternatives.

NYU Stern Professor Melissa Schilling, an expert in strategic management and technology and innovation management, finds that the cost of generating electricity with geothermal or wind energy is a fraction of the cost of solar energy. More important, the performance of both is improving much more per dollar of R&D invested in them than solar technologies. This is the first study to explore the trajectory of performance improvement of renewable energy alternatives.

Schilling examined data on government R&D investment and technological improvement and found that geothermal energy is the most efficient renewable energy alternative and is improving the fastest. Wind energy is second.

In addition, fossil fuel technologies are no longer improving (in terms of efficiency) much--if at all. These technologies have likely reached their performance limits, though the government still spends far more on them.

According to stern, geothermal energy could become cheaper than fossil fuels with R&D spending of as little as $3.3 billion.

Both geothermal and wind energy technologies have been underfunded by national governments relative to funding for solar technologies, and government funding of fossil fuel technologies might be excessive given their diminishing performance, the report concludes.

The full paper was recently published in Energy Policy and is available as a PDF at the link below.
