Renewable energy

Renewable energy is potentially [[environmentally friendly]], but not always. The "old renewables, bioass and hydroelectricity, generally have massive negative impacts:
* Burning biomass creates smoke, and [[indoor pollution]] which is a major cause of [[infant mortality]] in [[less developed communities]].
* [[Dams]], used for large-scale [[hydroelectric]] projects, cause massive environmental disruption, interfering with fish migration and breeding, preventing the natural flow of sediment and nutrients, and interrupting the natural [[water cycle]] with sometimes unpredictable consequences (such as the outbreak of the parasitic illness [[schistosomiasis]]{{wp supw|schistosomiasis}} following the year-round [[irrigation]] introduced by the [[Aswan Dam]] .
In 2006, about 18% of global final energy consumption came from renewables, but this is almost all from the old, damaging renewables: 13% from traditional biomass, mainly for heating, and 3% from hydroelectricity. "New renewables ([[small hydro]], modern biomass, wind, solar, geothermal, and biofuels) accounted for only 2.4%, but are growing very rapidly.{{fact}}
