Just been browsing the Energy Saving Trust website in the UK www.energysavingtrust.org.nz.
They are a UK not-for-profit thathelps people to save energy every day. Through impartial advice, commitment to undertaking research and work with businesses and governments, they influence behaviour change and new energy efficiency programmes and policies.
Their website has some interesting reports and tools – it’s all UK stuff but there’s some interesting research, such as heat pump field trials (including heating behaviour), a Water Energy Calculator to help households understand their water use and identify potential savings, and every year they publish how much money and carbon can be saved in the home across a range of things like insulating your home to buying the most efficient TVs.
