  2. Germany's wind power chaos should be a warning to the

    UK • 3,500 turbines in the UK produced 4GW (8%) • 23,500 turbines in Germany produced 31GW (27%) • 25th May 2012 Germany generated 22.4GW PV (30%) UK WIND | GERMAN WIND ENERGY STORAGE: THE NEED HYDROGEN ENERGY SYSTEMS On Friday, September 14, just before 10am, Britain’s 3,500 wind turbines broke all records by briefly supplying just over four gigawatts (GW) of electricity to the national grid. Three hours later, in Germany, that country’s 23,000 wind turbines and millions of solar panels similarly achieved an unprecedented output of 31GW. But the responses to these events in the two countries could not have been in starker contrast.
  3. GROWING WIND GENERATION IN THE UK • 2011: 6,488 MW

    wind capacity | 15,500 GWh wind production (DUKES 2012) • 0.5% of wind was subject to constraint payments • 2011 | 75MWh | £16m | 21p/kWh (full yr) • 2012 | 85MWh | £17m | 20p/kWh (to Sept, significant winter months not yet included) ENERGY STORAGE: THE NEED HYDROGEN ENERGY SYSTEMS
