Answer by bobweb
I believe “necessity is the mother of invention”, meaning that if the price of energy rises high enough for example, then people will start using less energy to save money. Then, new energy technologies that have been in development right along will finally start to compete in cost and people will start using those technologies more and more as their cost comes down. I think experts would say that energy costs will rise a lot faster in the next 20 years than they did in the last 20 years, so consider what investments might benefit from that trend.
