I have some broader green links on my renewable energy page.
Cars take up plenty of space and resources but do nothing most of the time and most cars run on a fuel which is under some other country's control and about to become much less available so everyone in rich countries will need to change their transport expectations soon, probably to something like The Netherlands or Asia where cheap two wheel transport has always ruled. Cycling is not just a good way to get around, it is the best way to stay healthy. The most surprising calculation that I have read recently is that extracting and refining petrol uses more electricty than an electric car would to cover the same distance and obviously then finally burning the petrol when driving causes yet more pollution. Cars cause so much congestion, so many problems, cost so much, carry so few people and are still stuck on 2-Dimensions, they are unable to travel directly point-to-point or over soft ground or water. However, both electric buses and electric aeroplanes work well over middle distances leaving electric bikes, scooters and taxis to get around within towns. I designed a version of the Opener Blackfly with tandem wings at 45 degrees back in 2016 but never built it. Their plane is brilliant and would be very welcome flying betweeen the 7000 islands of The Phillipines !
