2. 20 years ago when I got this job, I thought maybe solar would one day be 1% of global electricity supply. In 2024 it was about 7% worldwide, and rising fast. You can see this eating into fossil fuel power generation in, for example, Europe.

1. To opinions! Solar is the cheapest source of bulk electricity in many countries, and the quickest to deploy, and now you couldn't stop it being built if you wanted to. The limits to PV build in most places are grid access, permitting, and sometimes installation labour.

Thanks for your interest! We have lots of free videos on our youtube channel that could help you with the basics. Please check them out:) www.youtube.com/user/solaral...
