replacing fossil fuels as primary energy sources
Why?
Bad for environment
contributes to CO2 emissions
Will eventually run out
causes global warming and climate change
Mining is dangerous for environment
Alternate energy sources
Windmills
Hydroelectricity
Biomass
Solar power
Nuclear energy
Geothermal energy
Obstacles faced
Most of the world uses fossil fuels
Very expensive process
coal/oil mining very profitable
governments might not want to give that up
will require modifications to vehicles which run on petrol
New infrastructure will have to be built
renewable energy sources not very efficient
