"World Solar Capacity Reaches 101 Gigawatts!"

Posted by on Tue, Feb 12, 2013 at 8:54 AM

This is some good news from Inhabitat...

The solar power arrays around the world, from giant farms to personal solar panels, have the capacity to generate as much power as sixteen coal burning plants or one nuclear reactor, but with clean energy. As more and more solar arrays are installed in nations across the continents, the world’s dependence on oil and other fossil fuels shrinks, helping to pave the way for continued renewable energy in the future.
But we are still far from what appears to be very close...
Solar areas defined by the dark disks could provide more than the world's 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. The colors in the map show the local solar irradiance averaged over three years from 1991 to 1993 (24 hours a day) taking into account the cloud coverage available from weather satellites.

How much is that in jiggawatts?

Modern solar cells tend to have a 20-40 percent conversion rate. Biofilms run in the 8-12 percent range.

So we can ditch the plutonium and put some solar panels on the DeLorean to get Marty back to the future?

@3 no, the energy density is not high enough. Better to use steam like the Doc did.

That is actually a really massive amount of land when you think about it - is Chile really gonna want that sizeable an area of their mountains, stretching from their border to their coastline, covered in solar panels? And isn't that going to have pretty considerable effects on the ecosystem there?

.... why not FLOAT all of those solar panels, way the fuck out in the ocean in some of those red zones!? Eureka!
