what does non renewable energy mean
energy which will one day run out
what are the advantages of renewable energy
less carbon dioxide emission harms the environment less always available provides jobs some are carbon neutral
what are the disadvantages of renewable energy
expensive
unreliable
eyesore / looks bad
what are the advantages of non renewable energy
easy to access
cheap
efficient
what are the disadvantages of non renewable energy
lots of carbon dioxide emission
advanced greenhouse effect
won’t last long

what are the negative effects of renewable energy on humans
high upfront costs it can be an eyesore you can't use it everywhere it is unreliable there are limited storage capabilities
what is fracking
drilling down into the earth and pummping it full of high pressure water mixture to release the gas inside
what are the positives of fracking
it provides a lot of jobs
it provides reliable and affordable energy
it generates lot of money
what are the negatives of fracking
it uses a lot of water the fuel is very high in carbon lot of energy is needed to obtain the fuel causes earthquakes causes groundwater contamination leads to gas leaks
