I agree that solar is significantly less attractive in high-latitude, cloudy locations, though. All of those panels that Germany installed would have been much more useful in Arizona.
Hydrogen, of course, is a boondoggle: it's primarily a fossil fuel, needs a whole new distribution system, is less efficient than pure electric, and requires very expensive vehicles.
- Qwertious 10y agoHydrogen isn't even a power source - it's equivalent to batteries, not electricity.
- usrusr 10y agoWorse than that: if you buy hydrogen today (e.g. for some fuel cell car prototype), it is almost certainly created from fossil hydrocarbons. So hydrogen is not even a battery now but just a very elaborate way to burn fossils. "Equivalent to batteries" is the best case future scenario (e.g. in presence of abundant electricity from controlled fusion power plants).
