It's not just the public sector tossing $$ at Alt-energy.  More importantly,  R&D is and has been increasing yoy from private sector, (thars gold in them thar hills).  More and more businesses are incorporating solar and geothermal energy into their infrastructures and L/T models, and private funding for large alt-energy projects is also on the rise (and profitable as a business).  150 years of global fossil fuel dependency and infrastructure growth will not end with a 180 or fast enough for the most environmentally concerned.  But it will and is happening.
