I think we could do it in a single decade if we set our minds to it and made it a national priority
Do you mean entirely converting the country’s energy supply to alternative energy sources, or just offsetting the increased demand with new alternatives? I think the latter is certainly possible, but it would be a massive undertaking. Converting the entire power supply over would be a much bigger task.
Aren’t there something like 1,500 coal-burning power plants in America? Replacing all of those would take decades at least, and that doesn’t even address what it would take to replace the 100 or so existing nuclear plants. There’s also the problem of creating factories to create the hundreds of thousands—perhaps millions—of solar panels and wind-powered turbines needed to make that changeover happen. Just building factories that could handle that demand would take years. (Might be an idea for saving Detroit, though.) I think we’re talking about 20 or 30 years worth of work here, if not more.
That said, I think it’s well-worth looking into. A few decades is a blip, really, and the long-term gain would probably be worth it, particularly of we can get the existing energy use down to complement it.
