@wizzwizz4 Its pretty much the only point I see everyone agreeing on regarding energy-efficient computing!

I particularly like solar.lowtechmagazine.com/2009 , & I'll ask @gerrymcgovern for more.

As for whether its necessarily true... My best guess is that it'd take a massive reengineering of our entire hardware & software stacks. Probably including new datastorage technologies. Afterall they're doing a lot to be not quite as energy-intensive!
