Potentially, Europe could be covered with efficient wind turbines. Electricity would then be redundant. We still need fuel for heavy transport, airplanes, and auxiliary power stations in case of (unlikely windless periods over a (too) large part of Europe. Hydrogene is well known in this respect. But it is by no means an efficient fuel: it either must be compressed, or cooled to turn it in its liquid phase. It would be much better to turn electricity, water and air into a hydrocarbon, or even NH3. Could one think of electrolysis, in the presence of a catalyst, to create Methylal or Ethylal from CO2 in the air, combined with water? If fuel could be created this way with a reasonable efficiency, the use of fossil fuels could be halted in 2030.
