You may want to check actual data. The cost of solar is dropping rapidly, it roughly follows Moore's law, so in many places around the world it will be cheaper than hydrocarbons for many applications in less than ten years. In the same period you can expect the fracking industry to collapse. No need to argue about this though, you make your investments and I will make mine. Over a thirty year time frame, which is what I manage my portfolio to, I am confident my investments in alternative energy and the smart grid will crush investments in oil & gas.
