what is a nonrenewable energy source
Will eventually run out. Cannot be replenished in a human lifetime.
advantages of using coal as an energy source
enough to meet current demand
reliable
cheap to extract and use
disadvantages of using coal
Produces CO2
Releases sulphur dioxide
why is sulphur dioxide bad for the environment?
Causes acid rain
why is CO2 bad for the environment?
Contribute to climate change
advantages of using nuclear fuel as an energy source
Reliable
very energy dense
advantages of wind energy
no polluting gases produced
no waste products
low running cost
no fuel cost
disadvantages of wind energy
unreliable
dependant on weather
initially expensive
noise pollution
advantages of hydroelectric power
no polluting gases
low running cost
reliable
can be turned on to meet energy demands
disadvantages of hydroelectric power
initially expensive
dams can harm/ destroy marine habitats
what is a non renewable energy source
- Will eventually run out
- Not replaced at the same rate that it is being used
what is a renewable energy source
will not run out OR it can be replenished at the same rate that it is being used
