    "On Sunday, Germany’s ... renewable energy generation ... — nearly 75 percent of the country’s overall electricity demand by midday"

    "In the first quarter of 2014, renewable energy sources met a record 27 percent of the country’s electricity demand"

    “Once again, it was demonstrated that a modern electricity system such as the German one can already accept large penetration rates of variable but predictable renewable energy sources such as wind and solar PV power ...In fact there are no technical and economic obstacles to go first to 20 percent of annual electricity demand penetration rate from a combination of those two technologies, then 50 percent and beyond by combining them with other renewables and energy efficiency measures and some progressive storage solutions at a modest level.”

    And here in the UK nothing happened!

    I think that needs to be kept in perspective, even though it is impressive.
    They are connected to the EU electrical grid with much more interconnects than us. It was one day of low demand, and the article makes no mention of spinning reserves or imported energy.

    Would be a bit like saying that the Lizard Peninsular has 100% renewable electricity on some days (which it does).

    Though I do wish we would stop blocking windfarms and solar farms though out planning system and increase the amount more quickly.

    Colour me sceptical; I find the piece a little starry-eyed:


    “In fact there are no technical and economic obstacles to go first to 20 percent of annual electricity demand penetration rate from a combination of those two technologies, then 50 percent and beyond by combining them with other renewables and energy efficiency measures and some progressive storage solutions at a modest level.”


    No technical challenges in "progressive storage solutions"?

    Hmmm.

    Well, it's a far cry from the discouraging conventional wisdom that every wind farm requires a gas turbine to fill in its shortfalls.

    Not conventional wisdom in the industry, more a case of the anti wind brigade talking rubbish.

    Talk about taking stuff out of context. It says:

    no … obstacles to … some progressive storage solutions at a modest level …
    A challenge is something which might be difficult but is achievable. An obstacle is basically something you can't get past (though might be able to go around). Saying there can be some modest amount of storage with some difficulty seems entirely realistic to me.

    I think the annual electricity use will increase significantly but a combination of electrical storage at various levels in the system (point of generation, grid-wide and point of use) with a lot more demand management (via smart meters, etc) which effectively store positive and negative amounts of energy at the point of use (in car batteries, hot water tanks, freezers, laundry baskets, UFH slabs, …) will be the way we go. Again, a challenge but not an obstacle.
