Electricity and the environment
The document discusses different types of energy sources including vampire power from appliances that use power when turned off. It also discusses renewable energy resources like geothermal, biomass, wind, solar, hydroelectric and ocean tides that do not get used up. Fossil fuels are formed from decomposed organic material but are non-renewable since they get used up, while nuclear energy splits radioactive atoms to release energy with no greenhouse gases but risks from radioactive waste storage and potential accidents.
Electricity and the environment
- 1. Energy and theEnvironment
- 2. Vampire Power • Appliancesthat are turned off, still use power
- 3. Renewable Energy Resources •Geothermal • Biomass • Wind • Solar • Hydroelectric • Ocean tides and waves
- 4. Fossil Fuels • Formedby decomposition of organic material • Carbon-rich (oil, coal) • Non-renewable b/c get used up
- 5. Nuclear Energy • Radioactiveatoms are split and energy is released • No greenhouse gases or pollutants released • Lots of risk to deal with the radioactive materials disposal and storage and potential for mishap
