Managing the variability of renewable energy sources
In order to comply with legislation from the European Union, the UK’s renewable energy target (to produce 15% of final energy consumption from renewable sources by 2020) may require between 35 and 40% of our electricity to come from renewable energy sources by 2020. After 2020, a higher proportion may be needed. A significant amount of this renewable electricity is likely to come from wind, and the variability of this power needs to be managed. Although aspects of the management of wind variability can be controversial, utilities the world over generally agree that there is no fundamental technical reason why high proportions of wind energy cannot be assimilated into the system. There is a large body of literature on the topic and the steady growth of wind power, worldwide, indicates that it is seen as a robust choice for reducing greenhouse gas emissions.
