> over a quarter of oil is used for things other than transport But doesn't transport have the biggest need for power density? Once renewable power density is

  it is used as a precursor in chemical synthesis, plastics and a variety of other products. you're not going to replace that with solar.

    Sure you will, but maybe later. Super cheap energy makes bio-plastics competitive. Massive solar farms passively making carbon chains when the sun is up. The reason no one is talking about it is that the transportation transition is lower hanging fruit.

      There is an interesting line of research into catalysts that use electricity to create stuff like methanol, acetic acid, etc from CO2 and water. Often when you see people comment on this they automatically assume synthetic methanol --> green washed automotive fuel --> yay and I can keep my F150 pickup. But more seriously, pure low weight hydrocarbons --> chemical feed stocks.

  Plastic production requires oil and improving power density of batteries doesn't help that. Heating houses to a US standard requires astronomical amounts of energy that will be provided by fossil fuels because they are cheap per BTU. Sure we could design better houses and use more efficient heating technologies like heat pumps, but those are being adopted a couple orders of magnitude slower than electric cars are.
