bio fuels and non renewables Flashcards
what are bio fuels made from
plants and waste
what are bio fuel’s
renewable energy sources created from either plants or animal dung
supposedly what are bio fuels
carbon neutral , some debate its only carbon neutral if you grow the plant the same time you burn them
are bio fuels reliable and why
they are fairly reliable as crops take a relatively short time to grow and some crops can grow all year round, however they cant respond to immediate energy demand
what is the problems with bio fuels
expensive
some worry growing crop specifically for bio fuels will mean there isn’t enough space and water to feed the crops
more problems on bio fuels
forests have been cleared
loss of natural habitats
deca and burning increases Co2 and methane emissions
what non renewables are reliable
fossil fuels and nuclear energy
what is good about fossil fuels and nuclear energy
there is enough to meet the demand and power plants can respond quickly to changes in demand
what happens if no new resources for non renewable energy is found
the fuels are slowly running out and they may run out in a hundred years
what are good about fossil fuels
aren’t expensive
fairly low fuel extraction
cost effective
what releases co2 in the atmosphere when burned
coal,oil and gas
what bad thing does co2 do
adds to the greenhouse effect and global warming
what does burning coal and oil cause
releases of sulfur dioxide which causes acid rain
what is acid rain harmful to
trees , soils, the environment
how can acid rain be reduced
by taking out the sulfer before burning fuel or cleaning up emissions
