Employment in wind and wave energy has doubled in the last three years to ten thousand in the UK accoring to Renewable UK. While it is still pretty small as sectors go, recent announcements of facilities in Hull, Edinburgh, Belfast and elsewhere show that this could be just the tip of the iceberg.
At the same time the country's carbon dioxide emissions have fallen by nearly 9%. I wish I could say this was the result of some big turn in technology or behaviour, but it is pretty much just down to the recession. The important thing to take from this, apart from the welcome reduction in GHGs, is that we need ambitious targets, otherwise we will hit them by default.
