Comment on The momentum of the solar energy transition

  Right now Sweden and Norway have 118GWh of hydro storage and there is more in other EU countries. That alone is enough to power the EU for two weeks or so. But even that is not entirly needed as Europe is large and diverse enough geographically to have different weather in different countries. So power can still be moved. Even on the worst day of last year wind and solar were still able to produce 8.5% of the EUs electricity production so 37% of average levels.

    At 2800 TWh of annual electricity demand/production in Europe, 118 GWh lasts for about 22 minutes. 2 weeks would take 1000x the storage capacity, about 100 TWh.

      Sorry, I mean TWh and not GWh. For Norway it is 87TWh as here: energifaktanorge.no/en/…/kraftproduksjon/

      and for Sweden as well: researchgate.net/…/228782162_A_Nordic_energy_mark…

      So yes it is a thousand times more, my bad for mixing up units.

        Thank you. However, that is the yearly amount of energy. Not the maximum storage capacity at one point. Like (dis)charging a battery once <-> discharging it many times over the year. So over the whole year this massive storage was able to produce the energy needed in 2 weeks.
