5,000-mile network could cut entire continent's carbon output by a
quarter
By Paul Rodgers

"An audacious proposal to build a 5,000-mile electricity supergrid,
stretching from Siberia to Morocco and Egypt to Iceland, would slash
Europe's CO2 emissions by a quarter, scientists say.
The scheme would make the use of renewable energy, particularly wind
power, so reliable and cheap that it would replace fossil fuels on an
unprecedented scale, serving 1.1 billion people in 50 countries.


I'm afraid there is no chance wind alone can become reliable, even in a scenario of a mix of renewable energy sources. In Europe, apart some hydro and geothermal, we have very few non intermittent renewables to substain a such grid


If it is one grid that spans all of Europe, wind might be a reliable non-intermittent source. In that case you get wind energy from so many places on the same grid that you could actually get a (statistically) large sample of the wind occurence (not in time, but geographically) If you take a large sample of a stochastic process (such as wind speed) then the averages converges to a steady value.
Thus by taking wind energy from very diverse places in Europe on one grid you might be able to build a reliable power plant.
