Can Germany show how the transformation from a carbon based economy to renewable works?

The actual data for electricity in Germany during 2014 is now available,  the fruits of a $200B investment in wind and solar energy. While one can show isolated times of a few hours on one or two days where significant (say >30%) electricity is generated by renewable sources, the total contribution each of wind and solar sources of electricity average to 8% of average demand, leaving fossil fuels and nuclear energy to provide the other 84% . The problem is that for significant periods during winter when there is no solar or wind energy, the entire peak annual demand must be provided from the older generators. Not a single old generator can be turned off because it is needed to cover intermittency. However the older generators are providing 84% not 100% of the energy as they used to, and they must now charge a higher price to cover the same depreciation and finance costs. In some cases it is worse than this: many for the gas turbines were designed for base load operation, and when used in load balancing mode, the constant acceleration and deceleration of the shaft shortens its life to an unacceptable degree. The owners are mothballing their assets for future base load operation rather than misuse them. The cost of electricity for Germany users is higher than elsewhere. Note that a doubled penetration of wind and solar will double these cost problems without any compensating relief.

Germans pay more for electricity than almost any other people on earth at a cost of $0.33 per kilowatt hour, compared to $0.19 in France and $0.13 in the U.S., for instance. The cost of electricity for an average family of four in Germany has doubled since 2000.

Neither wind nor solar is competitive without subsidies. If the subsidies and quotas were taken away, no wind or solar operation outside very special situations would be built. Further, the existing installations would continue only as long as their contracts are honored and they are cash flow–positive. In order to be competitive, without subsidies, wind or solar would have to supply electricity for less than $20 per megawatt-hour, the marginal cost of generating the electricity with gas or coal. Only the marginal cost counts, because the fossil fuel plants have to be there whether or not there is wind or solar. Without the subsidies, quotas, and 25-year contracts, wind or solar would have to get about $100 per megawatt-hour for its electricity. That gap, between $100 and $20, is a wide chasm only bridged by subsidies and mandates.
