Can all of the US (and World!) run on solar power? Elon Musk says yes,and the science seems good.
Apparently, it won’t even take that much surface area to do it. What this would mean for the US in particular would be energy would be locally produced, no drilling, burning, emissions, by products of creating energy.
There would be by products of making this many solar panels, this is not without some downsides, but it seems that this is a much better option that what we are doing now which is a patchwork of old grids, old technologies and many emissions.
Between wind and solar power, this seems more and more an achievable goal! Read more on Inhabitat.
