In this interview, San Francisco scientist Dr. Donald Aitken (www.donaldaitkenassociates.com), talks about the inevitability of a future with renewable energy, and insists that we have to stop thinking about how much oil and natural gas we have left, but just start converting to renewables. He makes a very positive and responsible point that the transition to renewables can be done very gradually and economically, using the gift of the current remaining supply of fossil fuels.

“The resources are here in great abundance. The technologies are fully developed now. We are not waiting for new technologies.”

In about 30 minutes he covers almost all kinds of renewables: solar, wind, biomass, tidal, hydrogen, and particularly efficiency. Dr. Donald Aitken trained as a nuclear physicist, but is now a solar architect and former lead scientist at the Union of Concerned of Concerned Scientists.
