How many more times does it need to be said?
The problem with intermittent wind turbines
Tübingen’s mayor Boris Palmer demands: “We need to double the number of currently 25,000 wind turbines in order to supply Germany.” What a mistake!
Even 50,000 wind turbines only lead to massive surpluses if the wind blows. Wind turbines have on average around 2,500 full load hours per year, but the year has 8,760 hours. In times of no wind, no electricity is generated, even if one multiplies the number of facilities. Zero times x is zero. The intermittency of renewable energy such as wind and solar require either backup fossil power plants or energy storage capacities.
Storage technologies can only do this tasks with excessive costs. Without fossil power plants to balance the intermittency of renewable energy there will be no guaranteed power supply in Germany, with fatal consequences for the competitiveness of German industry and the manufacturing industry.
It should also be known to the Greens that the expansion of renewable energy due to Germany’s Renewable Energy Law is completely ineffective in terms of CO2 emissions in Europe. The CO2 emissions in Europe are determined solely by the capping of the emissions trading scheme. New wind and solar power, in fact, set more emission allowances free.
These certificates float through the stock exchanges to coal power plants in other EU countries where they allow further increase in CO2 emissions which amount to the same level as the reductions in Germany. Besides additional costs for citizens and the devastation of nature, any expansion of renewable energy will not achieve a single ton of CO2 reduction.
