    ...In a country like Germany, new renewables now represent around 50% of the overall installed capacity, and more than 20% of the actual generation ...

    The chart you provided on German energy production showed renewables providing about 30% of actual production for only 3-4 hours a day.  I doubt that recalculates into 20% of actual energy production.

    That said, thanks for the interesting charts showing how PV solar power fits into the daytime base loads.

    Orly, it isn't evidence just because you downloaded it from the internet.

      was just an exemple to show some dynamics - and it dates back from 2011 - there's been quite a bit more renewable energy capacity built in the meantime (something like 5 GW of wind and >10 GW of solar).

      In any case, you can find the detialed statistics for 2012 here:

      New renewable generation continued its remarkable growth in Germany in 2012, reaching nearly 115 TWh. Most growth has taken place since the country introduced a modern system of feed-in tariffs in the year 2000. New renewables now compares with the generation from hard coal and exceeds that from natural gas, nuclear, oil, and existing hydro.

      Solar photovoltaics (solar PV) continued its meteoric growth in 2012. Solar PV generated 29 TWh in 2012 or nearly 5% of total generation. Wind accounted for a little more than 7% of generation and biomass provided nearly 6% of generation.

      Renewable generation provided nearly 22% of total generation in 2012. Within a few years, renewables will account for one-fourth of all German electricity generation. New renewables accounted for nearly 19% of total German generation in 2012.

      So that's 7% wind, 6% biomass, 5% solar PV, plus 3% traditional hydro in 2012.
    •  look at the monthly chart (0+ / 0-)

      in the summer they are passing 50%.
