Germans pay some of the highest electricity prices in Europe, 31 cents per kWhr compared to 17 cents in France and 18 cents in the UK ( Economic Times).
Since humans need about 3, 000 kWhr per person per year just to have what we consider a decent life, this means the world must produce over 30 trillion kWhrs per year just to eradicate global poverty, war and terrorism.
Costs for coal are highly dependent on the cost of gasoline, and the costs for wind are highly dependent on material costs like steel and concrete as wind requires about 10 times the amount of steel, concrete and copper per kWhr than any other energy source.
