Several people have told me that solar and/or windpower are useless because the amount of energy necessary to manufacture them is less than the energy they can output over the entire life of the device.  That’s uninformed nonsense.

And don’t try the “it’s too expensive” argument either because now solar is actually cheaper than coal.  Which is a very very good thing considering that if we don’t get CO2 levels down to around 350 ppm real fast, we’re in real trouble.

Wind and solar aren’t the be all and end all of clean energy either.  My city uses poop to generate power at the waste treatment plant.
