Solarpunk

Lots of options. Lets start with a simple one: Bicycle repair shop.

Solar Installer or Wind turbine installer. Manager or project manager at companies that do solar or wind power installations.

Artist who builds sculptures out of scrap metal and/or trash or recycled objects.

An updated version of 'junk yard owner', possibly refurbishing or otherwise breathing new life into objects that would normally be trashed, and selling them to new owners.

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.

Librarian!

Almost any job that currently exists with a focus on sustainability and recycling. Lots of tech, bio jobs. Also artists and farmers Architects etc.

It needs to be a cultural shift for existing jobs away from profit insentivised goals and instead towards the sustainability of society, culture and nature.

The better question would be what jobs are not needed in a solarpunk future.
