  • paywalled. Chinese subsidies for EVs and solar are far less than US ones. China does make sure an abundance of minerals exists, refineries to process them locally. Key industries have access to cheap loans, but often new companies/projects have the same access as leaders. US system favours free money instead which is subject to using it as a slush fund instead of building a successful project that will pay back normal loans.

    China’s early success on EVs was based on city policies of restricting non EV license plates to certain days of driving. This is free. Having a good charging infrastructure/network also makes EVs an easier decision.

    Still, the US is improving enough to get good EV growth, and EV dominance soon enough. Equinox EV is better than model Y. Ford transit van is cheaper electric than ICE, with additional operating cost savings, and as a city vehicle enough range for a full day, and contractor benefits.

    US policy is based on pure lies to protect oil oligarchy dominance, but there is still a certainty/path for EV success.




















  • Pump storage is indeed very cool. However if one would count it twice when it is produced by solar and then again when getting it back from the storage, then that would majorly distort the statistic. You’d effectively count the produced amount of energy double (minus whatever efficiency loss you have from storing it).

    If batteries are charged by renewables, then counting the battery output as renewables is fine, as long as you don’t count the charging. Same for pumped storage.

    The point though was that existing hydro can be enhanced because it runs at spare capacity. Compared to dedicated pumped storage projects.


  • Hydro is very variable power output. If drought last year then can be a huge jump this year. Hydro in general, globally, averages 45% capacity. A good way to boost that is to use solar to power pumps bringing water up to the high side during the day.

    Onshore only growing by 6% is disappointing and I imagine a lot of it still has to do with resistance from nimby people and the likes?

    Europe is mostly densely populated. Onshore wind is struggling in west due to noise, but best locations are already taken is an issue as well. Europe does do much better than US given less oil/gas protectionism politics.
