Technology alone won't save us, but it is pretty cool

There's no silver tech bullet that's going to let us keep consuming at the same rate without making any sacrifices or major structural changes. But tech still has a role to play, from batteries that keep the flow of wind power reliable, to perovskite crystal solar cells.

Automated drones are being used to inspect offshore wind farms in the UK for any maintenance issues. Since it's not that easy to personally inspect a turbine that rises 80 metres out of the sea, this is a huge cost saving, and cuts turbine offline time from 2 hours to 20 minutes.

And in Bangkok (and other places), residents and business owners are using the blockchain to trade renewable energy peer-to-peer, cutting out the middleman.

As far as carbon sequestration goes though, the most effective technology we have is still a forest.
