Study evaluates clean energy technologies and declares winners
And the winner is wind! According to a study done by Mark Z. Jacobsen, a professor of civil and environmental engineering at Stanford, wind the cleanest of the "clean energy" technologies. Other winners, in order, are concentrated solar (the use of mirrors to heat a fluid), geothermal, tidal, solar photovoltaics (rooftop solar panels), wave, and hydroelectric. The losers include biofuels, nuclear, and "clean coal," which Jacobsen says are not nearly as clean as currently touted.
Not a huge surprise, but he used an apparently new method:
Jacobson has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability.
