The big questions over a future with synthetic fuels

The real question then is what alternatives do we have. We can't continue to use fossil fuels, Purely electric cars aren't at GP distance yet (and throw up a lot of questions about the materials used in batteries anyway) and Hydrogen also requires a large amount of energy to harness, then were not left with many options. We absolutely need to increase our renewable energy usage, which is the first problem in a lot of cases.
