that's a necessary step in your learning process, but certainly not sufficient. I'd recommend reading the book, since it shows in greut detail the inner workings of Git along with the basic concepts :
yes it does, but indirectly : making solar panels comes with the cost of dumping them after they've been used, because they're not fully recyclable. (which comes after 15/20 years if not earlier). plus they use vast amounts of land when much power is needed.
so yeah, energy density is relevant when comparing technologies. otherwise, why aren't we all cycling to power our toasters / ovens / refrigerators ? because the energy yield is bad.
so no, you shouldn't dismiss nuclear, because it's insanity powerful for its cost.
solar and wind are great, but insufficient on their own.
huh
who would have thought that the front page of the internet could also be one of its many giant prolapsed flapping assholes ?
not just regrading to this specific issue though
