We’ll always have the Sun: solar energy and the future of humankind
Above, Rick (Humphrey Bogart) speaks to Ilsa (Ingrid Bergman) in the movie “Casablanca” (1942). Here, the sentence has been a little changed. In the film, the phrase refers to “Paris”, not “The Sun”. But in the debate on the future of civilization, there is only one certainty: we’ll always have the sun.

As it becomes clear that we must get rid of fossil fuels before they get rid of us, a question is being asked over and over:
“Can renewables replace fossil fuels?”
Some people have been sufficiently impressed by the rapid decline of the price of renewable energy that their answer is not only, “yes,” but that switching to renewables will be fast and painless. It will come simply as the result of the free market mechanisms, at most aided by a little magic called “carbon tax”. Then, economic growth will continue unabashed in the best of worlds.
Others take the opposite position. Noting that renewables require large investments in the energy infrastructure, that they don’t easily produce liquid fuels, that they can’t support energy “on demand,” and more, they conclude that renewables are useless; an illusion, if not an outright scam.
This viewpoint is further split in two views. One seems to welcome the collapse of an energy-starved economic system and the associated return to the Middle Ages, or even to extinction. The other simply sees fossil fuels as a good thing to be kept and subsidised. After all, CO2 is food for plants, isn’t it?
