It took ten years and $80 million, but the Danish island of Samsoe now produces enough energy to satisfy all its needs and still export 40 percent of its energy to the mainland. Going 100 percent renewable wasn’t easy, but the results have paid off handsomely. Farmers on the island who are powering their facilities with wind turbines are seeing a 6 to 7 year payback on those investments. And of course it’s remarkable that wind, unlike other energy technologies, is entirely compatible with agriculture.
First cattle graze a section of grass pasture then three days later free range chickens are brought in to eat the maggots from the cow manure, distributing it across the pasture in the process and leaving their own feces as well. Hens come in next, followed by pigs. By the end of the cycle the grass is composted by the worms and microorganisms in the soil into rich topsoil that will support more plant life.
Working with nature is a beautiful thing – and it only requires that we sit back and observe what nature wants to do and how we can steer it using its own processes.
