The appeal of something for nothing still is the same as the times when people bought snake oil as a cure all. Indeed a sucker is born every 10 seconds (compensating for birthrate since David Hannum was alive) so the perpetuum mobile sales pitch of wind/solar/tide energy is very popular. Never mind that all energy subtracted from the environment causes greater harm than energy produced by matter/energy conversion or even burning fossil fuels. As soon as enough windfarms are installed to alter windpatterns , enough solar panels have been installed to intercept the natural warming which actually causes winds the blow then the shortsighted will realize too late it was not such a good idea. Luckily i’m of an age i won’t suffer the consequences.
This has provided a nameplate electrical generating capacity of about 216 Gigawatts, nominally about ~22% of the total European generation needs of about 1000 Gigawatts.
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…
