  1. Natural gas has proven it can supplant coal, and burns cleaner. Then there's active development in storing energy, one of the most promising being pumped-storage hydro, which is basically a dam beside a hilltop reservoir created specifically to be released when renewables falter and recharged by pumping it back up during the daytime excess.

  2. Just ask the oil companies.

  3. Bicycles are cheap and quite effective (especially when specifically designed to haul cargo), but most places would rather skip straight to cars because of its other advantages to its users (superior shielding, electricity generation, less muscle use). The issue with green energy is convincing people that clean air and stable sea levels are totally worth the extra cost.

  4. Renewables already produce local excess, and there's active development in storing it for nighttime/calm winds. Besides battery advances, there's also pumped-storage hydro, which is basically using the excess energy to pump water back up a hill for a dam to use later.

  5. Clean air is pretty important to society.
