It’s not like we’re going to run out of sunlight…
Wednesday, April 11th, 2007Here’s an interesting map I saw on an environmental blog the other day that I can’t stop thinking about :

“Solar power systems installed in the areas defined by the dark disks could provide a little more than the world’s current total primary energy demand (assuming a conversion efficiency of 8%). That is, all energy currently consumed, including heat, electricity, fossil fuels, etc., would be produced in the form of electricity by solar cells.”
On the surface, this seems like one of those fun little activist infographics that makes it seem as if we’re one giant leap away from solving all of our troubles. Obviously this approach would have problems since these tiny dots are still hundreds of square miles in size, but considering the advancements in solar technology over the last few years and the fact that the area represented by these dots could be dispersed on roofs and other wasted space, I wonder how well an investment in solar energy would pay off. Would the costs (monetary and energy-wise) required to replace our energy needs with solar panels be worth it? Is the technology efficient enough yet to justify this sort of investment? What do you guys think?
