I disagree with you. Though government research does contribute to various things, in general, it is the free market that solves 99% of our technological issues. People buy windmills, panels and stuff because they want to live cleaner, but only those who can afford it. So there are two ways to make people greener: Come up with a cheap green alternative or make everyone wealthier because it appears that the wealthier a country becomes, the more they care about the environment, at last as best as we can tell.
