Every industrial activity pollutes. The question is, what pollutes more or less? Green energy also generates pollution and waste. But does it produce more than fossil fuels? What is more desirable more or less pollution?

Can green energy outdo fossil fuels? It depends on environmental factors. In cold, long, dark winters it can't. In sunny, warm and temperate climates solar energy is viable. In other places wind turbines might be more appropriate, as could harnessing energy from tides, volcanoes, crops that produce ethanol or methanol.

The problem we face is that the fossil fuel industry wants no competition. They want to retain their energy monopoly. People who promote green energy are not blind or dumb. The objective is not to destroy the oil industry. The objective is to reduce the amount of fossil fuel consumed to a sustainable level, rather than continue to increase the atmospheric concentration of pollutants. The public perception has shifted. People now want to see changes in the way we generate energy. "Drill, drill, drill" might have found resonance several years ago. Now people wonder "Drill and pollute what?"

In the future all this pollution will cause problems of agricultural production and human health. Trying to save plant and animal species is important. However, the real problem is going to be drier top soil, drought, desert expansion, and reduced grain production. That is the human impact of global warming. Like I said, 1 degree Celcius means 5 to 8% increase in the rate of water evaporation from the soil. The middle class will simply pay more for food. The poor will starve because they won't be able to afford it. We are not the ones who will pay the price. It is young people 50 years from now who will suffer and have to deal with the mess we leave behind. I certainly don't want my grandchildren to live in a wolrd like that.
