Alternative technology is a term used to refer to technologies that are more environmentally friendly than the functionally equivalent technologies dominant in current practice. The term was coined by Peter Harper, one of the founders of the Centre for Alternative Technology, North Wales (aka The Quarry), in Undercurrents (magazine) in the 1970s. Some "alternative technologies" have in the past or may in the future become widely adopted, after which they might no longer be considered "alternative." For example the use of wind turbines to produce electricity. Alternative technologies Alternative technologies include the following: Anaerobic digestion Composting Fuel cells Fuels for automobiles (besides gasoline and diesel) Alcohol (either ethanol or methanol) Biodiesel Vegetable oil Greywater Solar panels Silicon-based Photosynthetic "Gratzel cells" (Titanium dioxide) Landfill gas extraction from landfills Mechanical biological treatment Recycling Wind generators |
