We are pleased to see our electricity provider ranked best in this green power guide from the Total Environment Centre and Greenpeace. Have a look at: greenelectricityguide.org.au
We think Powershop are cool because of their position on the RET, and the neat energy usage graphing they supply, shows when your peak usage during the day. You can use this to EMS yourself — EMS is an Environmental Management System that can be made to the international standard ISO14001, all very formal and audited, but the principle is: find you biggest environment impact and set a program to reduce it.
In Victoria with our brown coal energy generation, electricity will be the biggest impact for most households and businesses. Graphing of usage is a big help in working out which appliance is using the most electricity. The Powershop graphs use the capability of the smart meter to give hour by hour readings.
