Reader tip of the month - turn it off!

We talk about technology a lot on the website, but technology by itself is not enough - it's the user that makes the most difference. It's no good having the most efficient boiler, if you turn the thermostat up high, and then open the windows when it gets too hot.  User-behaviour was the the…

How to choose the best low energy lighting

Traditionally we've measured the strength of our lightbulbs in watts. A 40 watt incandescent light bulb was dim, a 100 watt one was bright. However, that measure was misleading. Watts are a measure of power consumption, not of light. A 100 watt incandescent bulb needed 100 watts of electricity to…
