I think it's more likely we'll ban human drivers. Just this morning I counted over 16 silver/grey/blue-grey vehicles driving in pouring rain and light fog without headlights on. On average a computer driver today is probably better than a human, and they'll just get better as time moves on whereas human improvements are a bit slower to happen.

California does have geothermal potential, the rest of the US does not.

Really? Because I could have sworn the largest geothermal upwelling on the planet is located in Wyoming, Montana, and Idaho.

If you do the research and the arithmetic, you find that renewables can make a significant impact - 11% to 13% of our total energy needs.

Bullshit, wind and solar alone can potentially generate many, many times our current energy demands. To get an idea of just how little land would be needed to generate our current needss with even junk solar cells check out this page which has a handy graph showing 6 solar farms in desert areas that would work. Now granted, that's approximately twice the area that we currently occupy with road and parking structures, but it would be completely possible if we were to set it as a goal like we did with reaching the moon, put 5-10% of global GDP for the next few decades to work on converting to 100% renewables and we could get there easily. The problem is not the technology, or the availability, it is the will to do what we know must be done, because it is harder than the current path which we know leads to problems.

Nuclear has by far the lowest, but for the same reason that many environmentalists are still opposing the Keystone pipeline despite the reality of more incidents of environmental damage from the alternative (inefficient rail shipping with nearly 100x the rate of environmental exposure), it's all about emotion for many in the movement, not about what's truly, measurably better for the planet.

I had the exact same thought when I went to the site. I went to Bach's childhood home and they have a number of his harpsichords including at least two in playable condition and I was lucky enough to be there on a day when they were actually playing one of them! It's a very different sound from a modern piano, though through stylized play the artist on this recording has made a modern piano sound as close as I've heard to the actual instrument that the piece was written for.
