Yup. But until that happens, if ever, fossil fuel is what we have and use. Hell I live in Florida and if solar panels were viable everyone in the State would be using them.This is something I find annoying about many progressives. They seem to have no concept of the magnitude of the goal they're trying to achieve and it leads to a lot of stupid assumptions. I'm all about solar and other forms of energy but we really do have a long way to go before we can even flirt with the idea of ending fossil fuel use. I would love to see us invest more in solar R&D so it can get to the point where it doesn't need assistance in competing with fossil fuels. I truly believe that eventually solar will outpace fossil fuels. It's just a matter of developing the technology more.Fossil fuels are the king right now, and will be for a long time.
