Comment on Tripling renewables globally by 2030 is doable, says new IEA report

Fossil fuels end up doing the work of balancing the grid during times when wind and solar are low. That’s not ideal, but a world where fossil fuels are used to balance renewable provision is much better than a world where they’re the primary energy source.

That’s true, but only as long as your primary source/balancing source are fossil fuels. I can imagine a lot of them being burned during short and cloudy winter days + all nights in this scenario. If we want to avoid CO2 emissions, nuclear pps seems like the best choice today. But then we don’t need nearly as much renewables. Tricky situation, even worse for countries without much wind.

I work in the UK energy sector, and that’s definitely not true! About 1/3 of our energy comes from wind which is somewhat but mostly not stored.

Yep, because you are still relaying on fossil fuels and can adjust their output quite dynamically. But the more renewables power you have, the more fossil fuels you’ll burn when renewables aren’t producing.

Makes sense?
