A recent Science Blog entry popped up in my Google Alerts this week and I couldn’t help but take notice. “The world can be powered by alternative energy in 20-40 years, Stanford researcher says,” details the work of two California-based researchers who assert that more commitment on the part of the general public may rid us entirely of the need for fossil fuels over the next several decades.
According to Mark Z. Jacobson, the Stanford researcher who co-authored a new study with Mark Delucchi at UC Davis, “There are no technological or economic barriers to converting the entire world to clean, renewable energy sources,” said Jacobson, a professor of civil and environmental engineering. “It is a question of whether we have the societal and political will.”
The plan they outline relies heavily on wind, hydroelectric, and solar power but why not include biogas plants, like Exeter Agri-Energy, to help augment the complementary systems they discuss?
