On this topic and the government and scientists are only trying to make money and distract people from more important issues. It would be better left from the consumption of hydrocarbons. But it is money and nobody wants that.
It is a very delicate topic. If you want to take steps to combat the global warming, then I am afraid that it is going to cost us a lot of money. For example, the electricity may get up to 200% more expensive, if we phase out thermal power-plants in favor of solar plants.
