ANOTHER RENEWABLE MYTH GOES UP IN SMOKE
Date: 28/07/14 Matt Ridley, The Times

wind-costsIf wood-burning power stations are less eco-friendly than coal, we are getting the search for clean energy all wrong
On Saturday my train was diverted by engineering works near Doncaster. We trundled past some shiny new freight wagons decorated with a slogan: “Drax — powering tomorrow: carrying sustainable biomass for cost-effective renewable power”. Serendipitously, I was at that moment reading a report by the chief scientist at the Department of Energy and Climate Change on the burning of wood in Yorkshire power stations such as Drax. And I was feeling vindicated.

A year ago I wrote in these pages that it made no sense for the consumer to…

Not Much Wind, But Plenty Of Hot Air!

Bob Greene:

Not much electricity either.

Dave Ward has sent me some details of an onshore windfarm site in Oxfordshire.
The Westmill Wind Farm consists of 5 x 1.3 MW turbines, and their website provides live updates of output.

The chart covers two days, up to 18th July, when Dave took the screen shot, during most of which next to no electricity was produced.

Windspeeds were typically around 5m/sec, which, if my brain is working properly, works out around 11 mph.

Dave particularly draws attention to the dramatic variation in output at low wind speeds, even on an hour to hour basis or less.

The Westmill website goes on to list some of the “Facts on wind generation”:

Construction of Westmill Turbine at NightWind energy is often criticised for being unreliable. Critics claim that wind energy can never replace existing power stations, or remove the need for new power stations to be built…
