It's a challenge, but remember that there is a lot of money in trying to convince people about the status quo. I'd keep in mind the kind of tactics that fossil fuel companies will be using to convince people otherwise:

- Using old data - the price of renewables and storage technology have fallen through the floor but bad actors are quite happy to use outdated numbers to convince you that they're not cheap

- Ignoring existing downsides - renewables have issues and we shouldn't forget that, but it's easy to forget what we're replacing. e.g. Lithium mines are environmentally unfriendly, but you dig it out of the ground and turn it into a battery once (and bonus - it's recyclable). Oil and gas must be continually dug out of the ground and burned

- But China... - I don't think most people realise quite how quickly the rest of the world is pushing on with renewables
