This cuts to something I've been trying to point out as a problem ..... You can't build renewable energy with renewable energy.
Windmill power isn't going to provide enough energy to mine the ores, process the ores, mill the raw materials, build the raw components or the systems to build any of the above..transport the end products, whether windmills or solar panels to their end use locations.....and neither will solar.
We need to get over a huge energy hump if we're to implement any significant level of "renewable" energy independence. Getting over that hump will require more oil, more coal, and if we're smart, more nuclear. THEN we can be realistic with dreams of being genuinely green.
