E=mc^2

Here's an excellent and understandable article explaining E=mc^2 and what that means for renewable energy sources. It's a little long, but well worth it.By William Tucker

Understanding E = mc2

Ed. note: A few weeks ago, I had the pleasure of hearing William Tucker speak at a conference in Washington, DC. His explanation of E = mc2 was the best I had ever heard. Even better, Tucker explained how Einstein's equation applied to renewable energy sources like wind, solar, and hydro. His lecture was a revelation. It showed that the limits of renewable energy have nothing to do with politics or research dollars, but rather with simple mathematics. During a later exchange of emails with Tucker, I praised his lecture and suggested he write an article that explained E = mc2 and its corollary, E = mv2.

To my delight, he informed me that he'd already written such an essay and he agreed that we could publish it in Energy Tribune.

I love this essay. And I'm proud that Tucker has allowed us to run it.
