Factor Ten – is about making a ten-fold improvement in the use of energy and resources. It can also mean a 90 percent cut in your business or personal costs and its possible to achieve this today – possibly saving ourselves $9 out of every ten dollars.
The picture shows one example – LED downlights. Costing between about AUD 10 and 20 dollars per light, the lights use 2 to 3 watts each. A normal downlight would use 50 watts.
The lights shown in the picture will pay for themselves within 6 months. After this, it’s money in the bank. In addition they should last many times longer than an ordinary 50 watt halogen downlight. This saves you or your business the time and cost of replacing ordinary bulbs.
Of course the answer to climate change is not just about light – although the International Energy Agency finds we could cut global electricity consumption by almost 10% with similar changes. Nor is it (only) about changing light bulb jokes…. But it is a great illustration of profitable and meaningful change that delivers economic and environmental carbon advantages.
