Solar, although getting better, is still less efficient than wind.

Solar is oversold. 2 huge problems. Does not work well if you have a
cloudy week and at nights. Then you have to store the power to use it.

And that is before one gets to needing many acres of land to get a
meaningful quality. And by the way, using lots of plastics made from oil
to make the cells...funny.


Plastic? Don't think so. State of the art cells are doped silicon (plenty
of that around) which are then further processed with protective and
conductive coatings. Recent advances in the optical assemblies that focus
more of the available sunlight onto the cells is one of the significant
reasons for improved efficiency. About 25 years ago solar cell efficiency
was, at best, 15 percent.
Today it's up to a mind boggling 18-20 percent. Long ways to go.

Solar and wind are still a long, long ways from being a viable energy
alternative to replace fossil fuel. The 100,000 megawatt capacity of the
nuclear plants currently operating in the US only supplies about 20 percent
of consummed power.
Solar and/or wind can't even be considered to make up the difference, let
alone replace oil and nuc altogether.

I'm not sure about that. In this country, wind energy alone, accounts
for 13,000 megawatts, most installed in the last 5 years, and there are
estimates that wind alone, could provide twice our present energy needs.

Portugal expects 45% of their energy needs to be met by renewable energy
by 2015. Germany isn't far behind.

I don't think anyone expects *one* silver bullet. It's going to take
conservation, new technologies, and, perhaps, most importantly, a
comprehensive national energy policy, which this present administration
doesn't seem to have the stomach for. I'm not saying it will be easy,
but it can be done, and solar/wind should be part of the mix.
