Ok, not all the time, but last weekend at 5:50am on Sunday morning (8th Nov) Spain set a new record, hitting 53.7% of its energy requirements being supplied by wind energy.

As you can see from the graph above, the amount of electricity being supplied by wind, the light green portion of the graph, doesn’t go below 30% at any point in the 24 hours and is closer to between 40-50% for most of the time!

These are figures the world’s most ambitious countries are targeting hitting by 2020, at the earliest!

Notice also on the graph that the contribution from coal (the red band) during this period is in the low single digits, never rising above 6.4%.

And finally notice also that for a lot of the period significant amounts of generation is below the 0MW line – this occurs when the electricity is being either stored using pumped hydro storage, or being exported for sale on the international markets.

The Guardian reporting on this quoted Jos? Donoso, head of the Spanish Wind Energy Association

“We think that we can keep growing and go from the present 17GW megawatts to reach 40GW in 2020,” he told El Pa??s newspaper.

Windfarms have this month outperformed other forms of electricity generation in Spain, beating gas into second place and producing 80% more than the country’s nuclear plants.

Experts estimate that by the end of the year, Spain will have provided a quarter of its energy needs with renewables, with wind leading the way, followed by hydroelectric power and solar energy.
