Playing with data: FITs

This map shows data from Ofgem – total renewables capacity (in kilowatts, kW) registered under the Feed-in Tariffs scheme between 1 April 2010 and 30 September 2011, aggregated over Local Authority area. Click on the tabs at the top to show the installed capacity of the different technologies, and the different groups of installers. Slide the bar on the left to zoom in and out, and click on the map and drag it to different areas.
AD = Anaerobic Digestion
CHP = Combined Heat and Power
PV = Photovoltaics (solar electricity)

So we can see that:

  • most installed capacity is photovoltaics;
  • there is little CHP or AD that has registered for FITs (many AD installations will be too large to qualify, but the take-up of micro CHP has been disappointing);
  • there is a smattering of wind and hydro, mostly in Scotland;
  • domestic take-up has been very patchy, with distinct cool-spots around the south east, midlands, north of England and mid Scotland;
  • community schemes on the Orkneys stand out (the aggregate by LA masks smaller schemes such as on Eigg).

Of course, colouring a map in this way wrongly equates the visual importance of each LA with its geographical area, so I’m going to have a look at correcting by population.
