Most countries are pretty far away from the amount of renewables where you start requiring lots of storage. You can easily do 50% renewables for electricity with hardly any storage at all.
- Maximus9000 6y agoI agree, but not with the "50%" number. “Without technological breakthroughs in efficient, large scale energy storage, it will be difficult to rely on intermittent renewables for much more than 20-30 percent of our electricity.” Steven Chu, Secretary of Energy - 2010. https://grist.org/article/2010-02-22-energy-secretary-steven-chu-posts-nuclear-rationale-on-facebook/ https://grist.org/article/2010-02-22-energy-secretary-steven...

- Maximus9000 6y agoTechnically, from your own numbers... Denmarks intermittent renewables (wind + solar) is 43%. Germany is 34%. Biofuel & Hydro are not intermittent. I don't know, that's pretty impressive. Maybe they have international connectors with other countries? I think Germany buys Nuclear power from France? or maybe they have a super stable kind of wind.
- legulere 6y agoGermany is a net-exporter of electricity to France. Especially in summer when nuclear reactors have to be shut down, because the water temperature in the streams they use already is too high or when the tide is too low, or in winter when the rivers freeze.
- suster 6y agoThey export cheap wind-generated power to Norway when the wind is blowing, and import it back for a higher price when it isn't. Norway has a lot of hydro which they used the revenues from North Sea oil to install. (Their geography and population density also helps.)
