This post is based on Green Alliance’s new infographic The power of negawatts
We need to cut the emissions of the power sector. We can do this by building new low carbon power stations, or by using less energy – otherwise known as generating ‘negawatts’.
Imagine a 15 watt lightbulb replacing a 100 watt bulb. The 85 watts saved can be used elsewhere: these are negawatts.
