In EU27 today there is a production of approximately 1000 TWh/ electric power from nuclear and 350 TWh/y from hydro power. The solar power potential is probably around 200 TWh/y. The wind power production is approximately 100 TWh/y but with a potential of at least 1000 TWh/y. The total biomass resources available are in the range 8500-12000 TWh/y. This gives a total of 10 000 – 15 000 TWh/y, from which at least 4000 TWh/y as electric power. This can be compared to the present gross energy use in EU 27 that was 16 084 TWh 2009, and 3400 TWh/y electric power. We can also see that there is a potential to save approximately 4 200 TWh/y in households, offices, transportation and industry. The energy balance thus should be possible to obtain with only non-fossil energy resources. Another matter is the power in time and by region. The demand does not always match the production locally at each moment and this demands a robust transmission and distribution network. Therefore we need new business models making it attractive for the users to reduce the load when there is a difficulty to deliver.
