Germany Aims To Get 100% of Energy From Renewable Sources By 2035 (reuters.com) 153

Posted by BeauHD from the energy-of-freedom dept.
Germany aims to fulfill all its electricity needs with supplies from renewable sources by 2035, compared to its previous target to abandon fossil fuels "well before 2040," according to a government draft paper obtained by Reuters on Monday. From the report: Economy Minister Robert Habeck has described the accelerated capacity expansion for renewable energy as a key element in making the country less dependent on Russian fossil fuel supplies. According to the paper, the corresponding amendment to the country's Renewable Energy Sources Act (EEG) is ready and the share of wind or solar power should reach 80% by 2030. By then, Germany's onshore wind energy capacity should double to up to 110 gigawatts (GW), offshore wind energy should reach 30 GW - arithmetically the capacity of 10 nuclear plants -- and solar energy would more than triple to 200 GW, the paper showed.

    We, the Dutch, the western neighbors of Germany, are ideal for US data centers.
    We are politically stable, have very few religious fanatics or warring tribes, very little seismicity and no volcanoes. Also we have the major connection point of transatlantic internet cables: the Amsterdam Internet Exchange; the biggest IX in the world.

    For example, our government in its infinite wisdom has awarded 13 billion euro (14.3 billion US$) in subsidies to Facebook to build a data center in our country that will use a considerable amount of our renewable energy to serve the Middle East and Africa. This one and several other data centers will make it nearly impossible to reach our climate goals. If the Germans could fall into a similar trap, they are in for a treat and will never make this proposed climate goal.

    Meanwhile, given winter (little pv) and wind dorughts across the whole of Europe, at least 30 days of power needs to be stored. All the good hydro sites are gone, that leaves you with batteries. There is not enough lithium mined to build batteries on that scale. So Germany will continue to rely on polish coal and France's nuclear to see it through winter. Hypocrites.
