In a recent speech, Al Gore poses a bold challenge to the United States: producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.
Wow! Unfortunately it's not only bold, but very likely critical to achieve. But can it be done? It would require unifying and modernizing the US energy grid, harvesting solar, wind and geothermal energy, producing cars running purely on electricity, and much much more. Brazil made the switch from foreign oil to only homegrown ethanol in only a few years . Still carbon based and pollution emitting, but a bold change. To me, it seems possible, especially given the engineering and financial resources of the USA.
What do you think?
