Energy can be harnessed from renewable sources such as hydropower, wind power, solar energy, geothermal and biomass.
Many energy suppliers now offer a ‘green tariff’. Many green tariffs provide electricity sourced from renewable resources. To find out more contact your energy supplier directly or use a search engine to find other suppliers of green electricity or visit http://www.greenelectricity.org/.
Check carefully what exactly your supplier’s green tariff means. Some provide the power directly from a renewable resource; others involve carbon offsetting or investing in renewables. Some even include planting of trees in addition to help reduce the impact of carbon emissions from burning fossil fuels.
