I'm all here for the green energy. I think it's worth investing in "both sides of the coin", though. Now that I've replaced all the energy-wasting bulbs in the house with LEDs, and the house is well-insulated enough that there's just no need to run a three-bar electric fire to keep warm, then I'm at the point where solar panels would be sufficient for nearly all my energy requirements. That's partly because solar has got better, but mainly because I'm just using loads less
On that note, the secret to not having power and cooling issues running tens of thousands of super-hot GPUs in the desert, is not to build them. Which as they're not being built, might be enough ;-) But investing in more effort processing units and more efficient models would do it too. They wouldn't have their "no one else can afford this" moat if it was all made more affordable, tho.
Get some Hendo's relish on it as well - meal for for a king.
