You can generate at least 50% of the electricity with hardly any storage at all, more if you integrate heat and transportation in the network. The world is very far from the levels of renewables were storage is strictly necessary, which is why there is not very much storage being built right now.
There is no real need to reduce energy consumption. We have plenty of space to build solar panels and wind turbines. But primary energy consumption will naturally go down a bit when you replace ICEs (30% efficient or so?) with EVs (80% efficient or so?) and oil and gas heaters with heat pumps (2
4 times as efficient). Of course electricity consumption will be way larger.
- xupybd 5y agoAre you sure about that we could get as high as 50% without storage? I was under the impression that storage is the crucial missing piece?
- adrianN 5y agoMy source is the German Wikipedia [1], that claims up to ca 60% with sufficient integration, and the fact that Germany managed 50% renewables in 2020 [2] without grid scale battery storage. To be fair, we could rely on the European grid to act as a sort of battery, which is why we managed such a high percentage with very little of the systems integration that the Wikipedia suggests one should do in this phase of the energy transformation.
