Power from wind farms prevented the creation of almost 36 million tonnes of greenhouse gas emissions from sources such as coal and gas in Britain, in a six-year period - the equivalent of taking 2.3 million cars off the road, analysis of nationwide output shows.
Researchers are scaling up a prototype iron-flow battery to provide cleaner and cheaper power when renewable energy sources are ebbing or demand is peaking. The battery would also efficiently store excess electricity when use is low.
The European Commission's Joint Research Centre has produced a dataset of wind energy production (EMHIRES) at national, regional and local level across the EU, by the hour for the last 30 years, based on existing wind farms.
In future, greenhouse gas carbon dioxide could be removed from the atmosphere by deploying a new biological method. Scientists have developed a synthetic but completely biological metabolic pathway based on the model of photosynthesis that fixes carbon dioxide from the atmosphere 20% more efficiently that plants can photosynthetically.
The optimized process of microbial electrosynthesis opens up further perspectives for the future production of biofuel or for the storage of power from regenerative sources in the form of chemical products, for instance.
