As for safe energy, in all respects, watch Sorenson's video, and read the link below.
However, the problem we face with Al Gore, whom I've supported, is that he erred in becoming anti-nuclear without thoughtful examination. It remains the safest form of mass generation ever deployed by mankind. Al should think about why folks like James Hansen now advocate rapid nuclear deployments, as the Chinese, for example, are doing.
What also seems missing from Vice Pres. Gore's statements (and others; here) is that global warming & sea rise are peanuts compared to the real threat. Combustion folks have already won. They've converted >500 billion tons of fossil carbon to $ in their accounts. And, they didn't even have to pay for the O2 they needed. NASA has to!
The real threat is years away, not decades -- ocean acidification. The seas' life forms provide most all carbon sequestration, as they die and their shells/skeletons form limestone on sea floors. We are 0.1 pH away from shutting that down. This makes oceans more nearly acidic now than at any time in the last 300 million years.
The natural carbon cycle via sea life & weathering can sequester <0.3 billion tons of carbon per year. Our debt, in air & sea now is >500 billion tons, Do the math.
Read papers by Caldeira at Stanford, DePaolo at UC Berkeley, etc. Even if all combustion stopped at the end of this sentence, more CO2 would continue to dissolve from air to seas, further acidifying them. In just 150 years, we've moved all ocean pH half way to shutting down not only sequestration, but the food chains that sea life, and we, depend on. If one thinks global warming is bad, sea rise is bad... then consider what is already happening in N. Atlantic waters and will continue to worsen, threatening about 20% of all human food protein -- that's what seas have delivered us and soon will not.
Pres. Kennedy was beginning a combustion-power solution in 1962: http://tinyurl.com/6xgpkfa
The continuation of this path would have led us to zero combustion for power by about 2000. The politics of the Cold War curtailed funding, however, so what Sorenson and I talk about in our links died for lack of funding in the '70s -- this despite successful safe nuclear prototypes operating in the '60s. We got to the Moon, but we failed to stop trashing our home's carbon cycle.
Al needs to rethink his unwise anti-nuclear stance, as we all must. The Chinese, Russians and others around the world are busy working to eliminate emissions via nuclear, because they know wind/solar 'farms' can't.
Our future has 3-legged, stable support in: a) local solar, b) EVs & efficient storage, and c) advanced nuclear. It's past time to act on that reality.
a) wasn't a reality in JFK's time,. It is today and still improving. b) also was not practical -- it is becoming so now. c) was practical in JFK's time and remains so -- the French have demonstrated for us all how nuclear power can eliminate emissions, and provide a major country with all the power it needs. The "attach" button seems to have gone away, so the graph showing French triumph over emissions and nuclear ignorance will have to wait.
Al, in any case, should know all this. But now we need leadership on combating acidification via real action on ocean chemistry. This is what we inherit by being foolishly anti-nuclear for decades. Our descendents are looking back at us from the future. We've not been doing well. If we fail to prevent another 0.1 decrease in ocean pH, our descendents will have every right to spit on our graves.
Harsh? Ma Nature doesn't care how dumb we are. As the present Vice President said, among our rights is the "right to be stupid". What that means is that others have to think and act, if any are to survive.
A decade or so ago, our energy debt was the need for 1GWe of non-emitting power put in operation every week. Now, we need that every day, plus another, equal amount to provide materials to protect ocean chemistry. Thus is our penance for ignorance, bias and sloth.
