He read AL Gores book 25 years ago, he should go read it again, he would find that he should not be able to read it today because AL said half of the US would be under water and he should be DEAD! AL the same guy who barked about the rising seas bought his million dollar ocean front property! The technology is coming, the problem is the government is led by greedy fools who only want power. I have solar on my house, and for about 9 months a year it does a good job, I can make a lot of kWs a day, because that thing in the sky shines from about 6am to 9pm, unless of course its RAINING or just plain cloudy! But from experience, this month here in Indiana where that bright object in the sky has disappeared, I will be lucky to make 25 kW total this month, the problem is I need 35 to 45 kW a day to meet our home electric needs. Sure you can build these billion dollar solar farms, but that does not do anything for you if the SUN doesn't shine! Solar can be a good supplement to fossil fuel and Nuclear(but wind and solar are just expensive, PERIOD), and please quit putting those solar farms on good farm ground, we need to feed the masses. Oh by the way, that Volcano going off in Hawaii will spew more green house gasses every Day than all the cars in the US will for a year!
