Nuclear (Stewart Brand) vs. renewable energy (Mark Z. Jacobson) at TED

Stewart Brand of Whole Earth Catalog fame is a long-time environmentalist who in recent years decided nuclear was necessary. (He also decided no-till was necessary, which was enough to convince me he’s gone barmy.) Here at TED he debates Mark Z. Jacobson, whose new study says we can power the world with wind, water, and sun. I think Jacobson should reconsider including building more hydroelectric dams, but his study does demonstrate that we don’t need nuclear or biomass. But watch it and see what you think:

Here is my critique of Brand’s arguments: Continue reading

How to power the world with Wind, Water, and Sun

…a new study just published in the journal Energy Policy states that the world can provide for all of its energy needs, including electric power, transportation, heating/cooling, etc using only wind, water, and solar (WWS) energy by the year 2030.
By water the study authors, Mark Z. Jacobson (pictured) Mark A. Delucch, mostly mean hydroelectric power, which would involve building more dams, with all their environmental problems. Still, it’s an interesting study demonstrating that true renewable energy could power the world: no coal, no oil, no nuclear.
