Q

Oil disadvantages

A

-non renewable
- greenhouse gases released (pollution, global warming)
- Sulfur dioxide-> acid rain
- oil spills= mass pollution (bad for environment)
- money from oil drilling-> might go to terrorist organisations

17
Q

Gas advantages

A
  • short start up time (natural gas)
  • impurities removes before use
18
Q

Gas disadvantages

A
  • non renewable
  • greenhouse gases released (pollution, global warming)
  • less harmful than oil or coal, easy preservation
  • easy storage + transport
19
Q

Nuclear advantages

A
  • no greenhouse gas emissions
  • much more energy can be generated per KG than for fossil fuels (more efficient)
20
Q

Nuclear disadvantages

A
  • fuel rods contain radioactive waste ( have to be stored safely for long time)
  • usually safe, explosion could release waste of vast area (affecting for many years)
  • long start up time
  • cost of building + using power station is very high
21
Q

Biomass advantages

A
  • mostly no harmful CO2 emissions
  • abundant + renewable (comes from living sources)
  • taking waste that otherwise might be harmful to the environment + making it useful (reduces landfill)
22
Q

Biomass disadvantages

A
  • expensive
  • inefficient, compared with fossil fuels
  • releases methane gases during combustion (damages the ozone layer)
  • smell given off attracts pests + bacteria
  • lot of land required to burn, ruining animal habitats
