The actual measured output by 2014 from data supplied by the Renewables Industry has been 38 Gigawatts or 3.8% of Europe’s electricity requirement, at a capacity factor of ~18% overall. However Renewable Energy production is dependent on the seasons, local weather conditions and the rotation of the earth, day and night.
So the Renewable Energy contribution to the electricity supply grid is inevitably erratic, intermittent and non-dispatchable. It is therefore much less useful than dispatchable sources of electricity, which can be engaged whenever necessary to match demand and maintain grid stability. That 3.8% Renewable Energy contribution to the grid is often not available when needed and obversely its mandatory use can cause major grid disruption if the Renewable Energy contribution is suddenly over abundant.
