E-bike repair and sales.

Electrician, as household remove gas appliances, they will be switching to electricity. Any building trade, actually. There are going to be a lot of houses and buildings that will upgrading to be more green, and as climate effects will be stronger, houses will have to be built stronger to withstand a more angry mother Nature, and more insulated.

Given the number of houses that will be needed to replace what we have, this will be a boom industry for years. Factory built houses that are field assembled is one area that could be high growth. I expect 3D printed houses, and underground houses to be a trend, too.
