In Germany, electricity prices are very high because of taxes, high electricity grid charges (these are quasi monopolies) and because of the special way in which electricity prices are set on the electricity exchange where the "
merit order principle" applies (where the power plant with the highest electricity costs determines the electricity price for all - first the electricity demand is served with the cheapest power plants [solar, wind, nuclear], then with the next most expensive ones, until the electricity demand is covered and the electricity price from the most expensive power plant [these days mostly by natural gas power plants] then applies as the electricity exchange price for all).
If the total annual share of renewable energy in Germany were not 50%, the price of electricity would be even higher.
Of course, it is better to use natural gas instead of coal for electricity production. But what is not included in the electricity prices from gas-fired (or coal-fired) power plants is the Social Cost (SC) of Greenhouse Gases.
An idea about the magnitude of this is provided by
EPA. A gas-fired power plant in the USA has an average emission of 0.5 metric tons of CO2 per MWh. One metric ton of CO2 causes SC of $120-340 (three scenarios in the EPA report), which is about 6-17 cents per kWh additional cost.
Those who generate electricity from gas-fired (or coal-fired) power plants are living at the expense of others - so we have to get away from that.
