Alt Energy and Trading Green

There is no such thing as green energy. Any kind of energy production creates some effects on environment. Wind is probably the cleanest, if you discount noise, thousands of birds killed every year and the fact that towers occupy a lot of land. Geotermal would be dead, at least open cycle, if you treat dump water the same way as industrial dump water. Solar might be a huge contributor to global warming, because solar panel converts 90% of solar energy into heat and only 10% into electricity. And it's doing it right now, not in the future, like CO2 (possibly).

As for "clean" energy economics, there is none. Alternative energy can't exist without government subsidies. Means taxpayers foot the bill. Means you'll never get good profits. Some luck is possible, like First Solar (for now), but that's it.
