100% Renewables At 764 Euros Per Household Per MONTH… Germany’s 4.6 TRILLION Euro Green Energies Flop
By P Gosselin on 8. May 2019
The 4.6 trillion euro German green energies flop
By Prof. Fritz Vahrenholt and Frank Bosse
(German text translated/edited by P. Gosselin)
The demands for the phasing out of coal, fuel and natural gas are becoming ever more shrill in Germany. At first early this year it began with the bold proposal of the coal commission, half of which was occupied by green activists from the Federal Chancellery, calling on the phase-out of coal by 2038. Then came the demand by Green party leader Robert Habeck and his green friends for the phase-out of the internal combustion engine by 2030. And when it was very dry for four weeks in April, Annalena Baerbock declared a climate crisis and called for doubling the CO2 price and a strong regulatory law!
Now the Friday Children of Lummerland are demanding a CO2 tax of 180 euros per tonne this year, and that we reduce “greenhouse gas emissions to zero” by 2035, i.e. 100% renewable energies.
So far wind and sun cover only 2.5% of Germany’s primary energy needs
So it is worth taking a look at the study of the Academy project “Energy Systems of the Future” of the “Union of the German Academies of Sciences and Humanities” to see what’s ahead of us. All sectors, electricity, transport and heat are considered together. And look: 80% of the energy is produced by fossil fuels, 7.5% by nuclear energy and 13% by renewable energies. Once biomass (including biogas and biofuel) is subtracted from renewable energies, only 1.5% of primary energy is generated by wind power and 1% by photovoltaics (p. 10 of the study).
This is a long way from 100%. The study comes to the conclusion that if one wants to go the way of decarbonization, e.g. by 90% by 2050, then “around 1150 terawatt hours, almost twice as much electricity will be needed than today” will be needed (p. 10) because traffic and heat are also to be powered from electricity.
7-fold increase in wind and sun needed
Since only photovoltaics and wind power are considered, the study concludes:
Approaching abyss
The study also hints at the abyss that we are approaching in this way.
The dominance of the fluctuating renewable energies requires high flexibility on the electricity generation side and on the consumption side.”
In other words, if nature does not provide enough wind and solar power, you have to do without electricity for a while. It is interesting to note that even in the beautiful new world of decentralized green energy generation, it still wouldn’t be possible to go without large centralized power stations. The study estimates that some 60 – 100,000 megawatts of large-scale power plants, which of course would run on biogas or synthetic methane or hydrogen, would help prevent short-term grid collapses. For comparison: today’s large power plant capacity is 90,000 MW.
Storage absurdly expensive . . .

Since only photovoltaics and wind power are considered, the study concludes:
In this case, the installed capacity of wind power and photovoltaics would have to be increased sevenfold compared to today (with the same energy consumption).”
Today, we (Germany) have around 28,000 wind turbines with an installed capacity of 57,000 megawatts and 46,000 megawatts of photovoltaics. A sevenfold increase in the photovoltaic area would require covering almost all roof-facades and other residential areas possible in Germany. A sevenfold increase in the capacity of the wind turbines would change Germany even if the capacity of the individual turbines were doubled. Every 1.5 kilometres a 200-meter tall 3-5 MW turbine would have to be installed.
