If a picture speaks a thousand words, a multimedia-packed, animation-filled interactive town must speak a million. Which is why on the Greenpeace UK website we've launched EfficienCity (like Sim City, but greener) to explain exactly what decentralised energy is and how it works in practice (which can otherwise be a wordy business).

If you believe our government, you'd think we need nuclear power and coal to stop climate change, but come and pay a visit to EfficienCity, which shows how pioneering, real world communities around the UK are using decentralised energy. As a result, they're enjoying lower greenhouse gas emissions, a more secure energy supply, cheaper electricity and heating bills and a whole new attitude towards energy.

Anyway, enough of the words - just go and visit EfficienCity to discover a cleaner, greener energy future. Enjoy.
