Why wind threatens energy security

The IEA defines energy security as:Energy security refers to the uninterrupted availability of energy sources at an affordable price.”

Energy security then must ensure that at every instant generating capacity meets demand, otherwise we have blackouts. Moving from fossil fuels to wind power threatens energy security because it increases the likelihood of a  shortfall in supply. Such an event occurred last December (2012) at 5pm when with peak demand at 56 GW – All of UK ‘s wind turbines delivered essentially nothing (<0.1GW). Doubling the number of turbines to 10,000 would have made no difference whatsoever. Since then several coal stations have closed and energy security has diminished.

Detail of demand and power generation by different fuels. On December 12th at 5pm wind power dropped to 70MW or 0.01% of demand. Gas and coal reserves compensated. The risk of blackouts increases as fossil reserves fall and wind increases.

The recent Channel 4 program “blackout” shows how quickly  society collapses during any extended blackout. DECC beware !

An over-reliance on wind power will increase the likelihood of blackouts. The only way out would be to store huge amounts of energy cost effectively and this is highly unlikely. There are just not  enough mountains in the UK for pumped hydro storage.
