The Energy Letter concept was introduced in autumn 1989 in a move to provide home-owners with a statistical breakdown of their water and electricity consumption. Customers learn about their energy use and get an almost immediate response on Home with direct electrical heating efficiency measures applied. As a result of the project, the average amount of energy used per customer was reduced by 2,400 kWh per year. The Energy Letter does not require any investment cost.
Throughout the past decade, a considerable amount of experience has been gained from technology transfer programmes on energy efficiency and renewables energy technologies in the UK. This paper describes theessential elements of a successful technology transfer programme and gives details of some of these elements within the UK Department of Energy's Best Practice programme, its predecessor the Energy Efficiency Demonstration Scheme and the Renewables Energy programme.
