I'm a big fan of renewable energy (solar, wind), electric cars and likely electric planes (not yet available, so hard to say). But my biggest concern is that all this will eventually lead to people decisions being affected by rather this hipe, than common sense (like with nuclear power, which is the greenest currently available peak/off-peak source of energy). Something similar can also happen, as with Saturn 5/Apollo, after some time we will lose the technology, because people retire, workshops are disassembled. We can loose technology of efficient piston and jet engines, nuclear reactors, ultrasonic flight, et al. This by itself is fine, batteries work fine obviously, though one can imagine conditions where it is not the case: Antarctica, Mars, Moon, space, etc. Just look at Juno space probe, which instead of small RTG uses huge solar arrays, which produce just few hundreds of watts on Jupiter orbit, while being capable or producing kilowatts on Earth one.
