Why would an energy company want us to use less energy?

Talking Energy’s a great little interactive campaign, and nice to see that E.ON is helping to raise public awareness of what it calls the Energy Trilemma – i.e. how to balance security of supply, reduction of carbon emissions, and affordability.
The campaign’s all about encouraging consumers to use less energy, and E.ON hopes that by doing this it will help reduce household bills, engender loyalty and customer support, and ultimately drive long-term profit.
