Nonrenewable Resources
Resources that cannot be replaced in our lifetime and will eventually run out.
Renewable ResourcesResources that can be replaced over a logical period of time, or will never run out.
Wind Energy (Renewable)
Electrical energy generated by wind turning wind turbines. Advantages:
•It’s free•No greenhouse gases produced
Disadvantages: •Only can go in places with a lot of wind•You need a lot of turbines to make electricity•They are ugly
Hydropower (Renewable)
Energy generated by tides, waves, and dams.
Advantages: •It’s free•No greenhouse gases produced
Disadvantages: •Dams are expensive •Affects nearby wildlife•No rain = no electricity
Fossil Fuels (Nonrenewable)
Fuels found in the ground such as oil, natural gas, and coal. Will eventually run out.
Advantages: •Can be found in a lot of place in the world•Easy to transport•Cheap
Disadvantages: •Produces greenhouse gases such as CO2 (Carbon Dioxide)•Coal mines and Oil rigs are dangerous and harmful to the environment
Solar Energy (Renewable)Energy generated using solar panels to convert light and heat into electricity.
Advantages: •It’s free•No greenhouse gases produced
Disadvantages: •Expensive to build solar stations•Cloudy or night time there is no energy•They are ugly
Geothermal Energy (Renewable)
Energy from heat inside the Earth
Advantages: •It’s free•No greenhouse gases produced
Disadvantages: •Not very many places to build geothermal stations•Harmful gases and materials sometimes come up.
Biomass Energy (Renewable)From plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil Advantages:
•It’s cheap and from things that we usually throw away•Should not run out
Disadvantages: •Produces greenhouse gases such carbon dioxide•There is not enough space to grow biomass fuel
Nuclear Energy (Nonrenewable) Energy from heat produced when
splitting a Uranium atom through a process called nuclear fission.
Advantages: •No harmful greenhouse gases•A small amount of Uranium produces a lot of energy
Disadvantages: •Waste is Radioactive•Uranium will run out in about 50 years with our current use.
