“My bet is with the engineers and scientists who will find a way to make a better product once a market for it exists.”
As someone with an engineering degree, I can tell you biofuels and solar are at best going to be small parts of the solution, the numbers just don’t add up. You have to go nuclear to have any chance of making a dent in our energy needs. Conservation actually has as big a potential as biofuels or solar (which are resource hogs).
What kind of solar and what kind of biofuels are you talking about?
