For any readers in NZ, Nick Young (no relation) sent us a pointer to this Clean Energy Guide. Nick suggests:

If you live in New Zealand you can make the switch to clean energy by using the Clean Energy Guide to choose a new electricity supplier.

The guide is produced by Greenpeace NZ and rates New Zealand’s clean energy providers. I really like the “thermometer” diagram showing the various companies from hot (red, top) to cool (green, bottom).

The site seems to be the equivalent of the Green Electricity Watch (GEW) in Australia. GEW is a regular report produced by a number of environmental organisations, including WWF, that rates GreenPower products available in Australia.

The latest report was released in November 2006. GreenPower options from Origin Energy and TRUenergy were ranked highest.
