Biogas from animal waste in need of maturity
Biogas from animal waste in need of maturity
Livestock produces a lot of waste. One solution is to turn such agricultural waste into biogas to generate energy .  It requires using so-called anaerobic digestion, which consists in breaking down biodegradable material in the absence of oxygen.

In 2015 Denmark produced 42% of its electricity from wind turbines,  breaking the world record  of 39% that it set the previous year. But, this is only the beginning.
Smart grid: A grid suitable for renewable energy
Smart grid: A grid suitable for renewable energy
Traditionally our electricity grids were designed to move power from large nuclear and fossil fuel power plants to consumers, but renewable energy will see changes to allow smaller power generation from wind and solar to be hooked up to the grid.
