>>Again, energy will not be an issue in 30 years, unless you assume that for some reason all technological progress stops today. In fact, I’m guessing that we never actually run out of natural oil. The remainder will stay underground while synthetics/alternative energy sources are used exclusively.
I suggest you save this post and show it to your grandchildren in 40 years.
Energy isn’t just a question of technological progress. Solar energy is the source of all usable energy on earth with the exception of nuclear energy.
Coal, Oil, Natural Gas, Biofuel, Wind, Hydro, Food, Wood, you name it EVERYTHING comes from solar energy. There is a limit to how much of the incoming solar energy we can collect and convert, both practically and theoretically (=fundamentally). This is not a problem that we can “invent” our way out of. It is a fundamental limitation.
