I came up with 15 million acres of panels would provide all the US energy needs. We currently have 39 million acres of corn dedicated to putting ethanol in our gasoline.
- fghorow 4y agoA long time ago -- in a continent far, far away -- I did a back of the envelope calculation for the area of solar PV required to power Australia's total energy consumption (not just electricity, but heat, industry, and transportation too). It turned out to be something on the order of 20% of the land area in Tasmania (the island state just off the SE shore of Oz, for those of you unfamiliar with Aussie geography). Now, I am not for a millisecond suggesting that Aussies cover 20% of Tasmania with solar PV. But that area happened to be within about 20% or so of the estimates of roof area in the country. Food for thought.
