Which investment generates more energy? How about weighted by usefulness in various ways?
KWH per dollar during whole lifetime, solar wins, even when oil is subsidized (for national security reasons)
There are problems with solar that it is not a steady supply of energy, yet I would argue that it is better that way. People should sleep during the night, not work.
That’s a bizzare and frankly nonsensical argument. First of all, power is not just necessary when working (leisure, ac, etc use power too), secondly there are tons of jobs which have to be done at night. They’re not done at night “just because”. I’m sure many of those would like to “not work” at night, but then the world wouldn’t work… Then there’s also the problem that not everywhere has sufficient sunlight during winter. It’d be impossible to power Sweden throughout winter using only solar power for instance. Solar is great, but the solution to achieve greater adoption isn’t just to ignore the downsides with it, but rather to accomdate them.
