Germany demonstrates that the 'Green New Deal' would be an unmitigated disaster

Oddvar Lundseng, Hans Johnsen and Stein Bergsmark:

More people are finally beginning to realize that supplying the world with sufficient, stable energy solely from sun and wind power will be impossible.

Germany took on that challenge, to show the world how to build a society based entirely on “green, renewable” energy. It has now hit a brick wall. Despite huge investments in wind, solar and biofuel energy production capacity, Germany has not reduced CO2 emissions over the last ten years. However, during the same period, its electricity prices have risen dramatically, significantly impacting factories, employment and poor families.

Germany has installed solar and wind power to such an extent that it should theoretically be able to satisfy the power requirement on any day that provides sufficient sunshine and wind. However, since sun and wind are often lacking – in Germany even more so than in other countries like Italy or Greece – the country only manages to produce around 27% of its annual power needs from these sources.

Equally problematical, when solar and wind production are at their maximum, the wind turbines and solar panels often overproduce – that is, they generate more electricity than Germany needs at that time – creating major problems in equalizing production and consumption. If the electric power system’s frequency is to be kept close to 50Hz (50 cycles per second), it is no longer possible to increase the amount of solar and wind production in Germany without additional, costly measures.

Production is often too high to keep the network frequency stable without disconnecting some solar and wind facilities. This leads to major energy losses and forced power exports to neighboring countries (“load shedding”) at negative electricity prices, below the cost of generating the power.

In 2017 about half of Germany’s wind-based electricity production was exported. Neighboring countries typically do not want this often unexpected power, and the German power companies must therefore pay them to get rid of the excess. German customers have to pick up the bill.

If solar and wind power plants are disconnected from actual need in this manner, wind and solar facility owners are paid as if they had produced 90% of rated output. The bill is also sent to customers.

When wind and solar generation declines, and there is insufficient electricity for everyone who needs it, Germany’s utility companies also have to disconnect large power consumers – who then want to be compensated for having to shut down operations. That bill also goes to customers all over the nation.

Power production from the sun and wind is often quite low and sometimes totally absent. This might take place over periods from one day to ten days, especially during the winter months. Conventional power plants (coal, natural gas and nuclear) must then step in and deliver according to customer needs. Hydroelectric and biofuel power can also help, but they are only able to deliver about 10% of the often very high demand, especially if it is really cold.

Alternatively, Germany may import nuclear power from France, oil-fired power from Austria or coal power from Poland.

In practice, this means Germany can never shut down the conventional power plants, as planned. These power plants must be ready and able to meet the total power requirements at any time; without them, a stable network frequency is unobtainable. The same is true for French, Austrian and Polish power plants.

Perhaps more important, the amount of land, concrete, steel, copper, rare earth metals, lithium, cadmium, hydrocarbon-based composites and other raw materials required to do this is astronomical. None of those materials is renewable, and none can be extracted, processed and manufactured into wind, solar or fossil power plants without fossil fuels. This is simply not sustainable or ecological.  (Emphasis added.)

Construction of solar and wind “farms” has already caused massive devastation to Germany’s wildlife habitats, farmlands, ancient forests and historic villages. Even today, the northern part of Germany looks like a single enormous wind farm. Multiplying today’s wind power capacity by a factor 10 or 15 means a 200 meter high (650 foot tall) turbine must be installed every 1.5 km (every mile) across the entire country, within cities, on land, on mountains and in water.

There is more.

Big Greens' dream of electric cars replacing the internal combustion auto will also require fossil fuel to produce the steel and it will take fossil fuel to also produce the plastic, upholstery, and tires for such cars.

The article also demonstrates that the Green New Dealers have not developed a system that allows alternative energy to scale to meet demand up or down.  It is a critical problem that will restrict these sources of energy to supplemental usage until technology id developed to control output.
