Air dry clothes when possible Energy Generators: electrical generator (made up of a coil of wire and a magnet) Electrical Generating Stations page 327 1. Hydroelectric - water (mechanical energy) runs the generator – 2. Thermal heat (steam) from burning of fossil fuels runs the generator – 3. Nuclear heat (steam from nuclear reactor runs the generator Getting power Transformers are electrical devices that changes voltage so that it can be used by homes (120V and 240V). They can step up (increase) voltage or step down (decrease) voltage. Ex. Power adaptors are transformers (have to have the proper adaptor to rum your game system) Problems 1. safety 2. cost of production 3. degree of environmental impact Alternate Energy Sources Constraints of new Technologies Wind Generators 1. cost Solar Energy 2. availability of materials Fuel Cells 3. properties of materials See page 330-4
