Physics 1.5
Bio-fuels
renewable energy source
produce electricity or fuel cars the same was fossil fuels can
carbon neutral
reliable
cannot create energy on demand
produced continually and stored for use
very high refinery costs
worry it will increase food shortage
produces carbon dioxide and methane emissions
destroys habitats to make room to grow
non renewables
fossil fuels + nuclear = reliable
enough to meet current demands
power plants can respond quickly
will run out
cost effective so popular
creates environmental issues
carbon dioxide produced
adds to greenhouse effect
burning releases sulphur dioxide = acid rain
removing sulphur dioxide before burning = less acid rain
coal mining messes messes with landscapes
oil spills have major eco impacts
nuclear power is clean but waste is dangerous and difficult to dispose of
trends in energy resource use
still depend on fossil fuels
huge increase in energy use in the UK
efficient devises = less energy used
oil is used in petrol and diesel
gas heats houses and cooks food
more use in renewable energy
people want to use non finite sources
more aware fossil fuels will run out
governments targeting renewable energy use
cars can by hybrids or electric now
limitations of renewables
evidence cannot change the behaviour of governments or people
not enough money to built lost of renewable power plants
arguments about where to put power sources
not all resources are reliable
research to make them better take time and money
personal changes can be expensive
