World’s largest wind turbines;
Each wind tower comprises the following;
1,300 cubic metre concrete foundation. Energy required in concrete production = 893 megajoules/tonne – plus transport. 1300 cubic metres = 3,250 tonnes weight (2.5 tonne/cubic metre concrete). Therefore concrete foundation used 893 mj x 3,250 tonnes = 2,902,250 megajoules. When 1 megajoule = 3.6kw hours then 2,902,250/3.6 = 806,180 kwh the turbine would have to run just to replace the energy used in the concrete footing.
180 tonnes of steel, 900 tonne total weight including toxic blades made from rare earth minerals.
120m tall tower (40 story building), blades 61.5m long
And even more madness;
Norway wants to build a 180m (533ft, 60 stories) tall wind turbine to power 2000 homes at a cost of $67.5 million. That’s $33,750/house to build, plus blowout costs, running and maintenance costs, plus dismantling costs at end of life. The utter stupidity of the green religion.
And then there’s plans to build a wind turbine with a 164m diameter rotor – (the above ones have a rotor of around 126m) – utter, utter madness.

Ok so we see the futility of wind farms and how the only people they help are the rich who get massive government subsidies to put them in. For the rest of us wind farms are a blight on the landscape that run at around 20-30% capacity, don’t reduce fossil fuels, are made of toxic rare earth materials, kill protected wildlife and cause massive health problems for people.
Well here is some more geo engineering madness brought to you by governments drunk on the green kool aid and climate communism – they are wave farms.
The 600ft (200m) long Pelamis steel tubes with 4 generators inside with hundreds of gallons of hydraulic fluid forced through internal turbines by the motion of the sea. These monsters are placed in rows that cover square miles of ocean and are called wave farms. Bit ironic that the Greens who are so anti oil rigs will place thousands of these fossil fuel filled pods across pristine ocean with absolutely no problem – typical hypocrisy.
Pretty cool huh – NO
Where else but green bankrupt California ; Greens leading the world in ocean junk ; Europeans looking at riding the wave of green stupidity ; Scotland wants to gloat over it’s green madness
