Document Summary
Upgrading existing plants to increase their capacity d. iii. 1. Replace old turbines with newer, more efficient versions d. iv. Hydropower is renewable as long as streams have water flowing in them: disadvantages. Flooding large tracts of land destroys natural habitats and dislocates (often indigenous) people b. iii. Reservoirs have relatively short life spans due to sedimentation b. iv. Reservoirs modify water quality and reduce nutrient cycling b. v. Encourage earthquakes: explain why the development of alternative sources of energy on the earth is necessary. a. Energy crops (coppicing trees: can be used in several ways c. i. Effective insulation and/or shade trees: active solar techniques d. i. Flat-plate collector, transfer fluid, and radiators or a storage reservoir d. ii. Major use of active solar collectors is producing hot water: explain how electrical energy can be harnessed from the sun by photovoltaics, photovoltaics use semiconductor tech to directly generate electricity, or can charge hydrogen fuel cells b. i.
