Green energy tariff
Green energy tariffs are available from most energy suppliers.
If you adopt this type of tariff your supplier is obliged to source for you an amount equal to some, or all of the electricity you consume, from existing renewable energy sources such as hydro or a wind farm.
An alternative is a green fund. This involves you paying a premium to contribute to a fund which is used to support renewable energy developments. Some energy companies are offering a combination of funds and tariffs.
