Calculated to mislead

Today Scottish Renewables has issued a press release which the BBC has reported.  It claims that the renewable industry in Scotland is displacing CO2 emissions equivalent to 8.36 million tons.

There are (at least) a couple of problems with that.

1.  The figures appear to take no account of the additional carbon required to get wind generation up and running.  This includes the making of turbines, extra CO2 generation in transmission and back up generation required.

2. The figures include hydro power.  That will be the hydro plants which were installed between 1922 and 1965?  These facilities produce about 50% of 'renewable' electricity.  If my figures are correct that suggests the following quote from Scottish Renewables is deceptive:
"This is proof that Scotland's renewables industry is establishing itself as one of the most effective weapons in tackling climate change and addressing the greatest threat to our natural environment"
It is the present continuing tense which implies that what was established over 45 years ago is actually part of our brave new response to a (supposed) grave threat.

  1. But look to the bright side. Renewable energy shares are tumbling, as anyone with any sense gets out of renewables ahead of the Kyoto commitment ending on the 31st December and the only thing they have to look forward to is a job interview.
