The Total Environment Centre and Greenpeace have released a handy new version of their green electricity guide in which they rate the greeness of Australian electricity retailers by state. Have a look and see if you can change to a supplier with better environmental credentials from your current one. Those in Qld, NSW and Vic. have the option of buying their power from either Powershop or Diamond Energy which both received a much higher rating than all the rest. There is usually no transfer fee, no lock-in contract and the price you pay for electricity should be similar.
