‘How a false solution to climate change is damaging the natural world

In growing maize for biogas, the crop that does most damage to the soil is being specifically exempted from the rules…….

If you want to know where we might be heading, take a look at Germany. Two years ago Der Spiegel reported:

“Subsidies for the biogas industry have led to entire regions of the country being covered by the crop … Plans called for transforming Germany into a bio-wonderland by peppering it with numerous small eco-power plants. What resulted was a revolution in the fields, a subsidised gold rush – and an ecological disaster. Corn [maize] is now being grown on 810,000 hectares in Germany.”

As a result, “for the first time in 25 years, Germany couldn’t produce enough grain to meet its own needs.”

On some soils, the German Nature and Biodiversity Conservation Union estimates: “growing corn releases 700 grams of carbon dioxide into the atmosphere for every kilowatt hour of energy it produces. And this happens for years on end. This is comparable to the carbon-released-to-power-produced ratio of some coal-fired power plants.”  ‘
