Reflecting on my interviews with various leaders in the energy efficiency space there are five things you must have to successfully reduce energy use and carbon emissions.
First you need leadership commitment.
Second you need a measurement and monitoring system. Whether you are a school (listen to Hannah Lewis, Westernport Secondary College, which has halved its energy use in the last four years) or a major corporation such as Wesfarmers, you must be able to track your progress.
Third you need more than one person active and driving the program. Witness Linfox, where a few programmers voluntarily took on the extra project of building a carbon tracking tool.
Fourth you need a well informed plan as to what you need to do. An energy audit by experienced energy efficiency engineers will provide this.
Fifth, you need investment. Money is needed to get the savings. The money could be spent on people (eg the driver training undertaken by LinfoX) or technology (eg lighting upgrades at Darebin City Council and Newcastle City Council, or the new paint plant at Toyota).
Do this and with time you’ll have a self-funding system that will continue to reduce your energy use and carbon footprint.
