Nonrenewable Resources
Resources that cannot be replaced in our lifetime and will eventually run out.
2
Renewable Resources Resources that can be replaced over a logical period of time, or will never run out.
3
Wind Energy (Renewable)
Electrical energy generated by wind turning wind turbines. Disadvantages: Only can go in places with a lot of wind You need a lot of turbines to make electricity They are ugly Advantages: It’s free No greenhouse gases produced
4
Hydropower (Renewable)
Energy generated by tides, waves, and dams. Disadvantages: Dams are expensive Affects nearby wildlife No rain = no electricity Advantages: It’s free No greenhouse gases produced
5
Fossil Fuels (Nonrenewable)
Fuels found in the ground such as oil, natural gas, and coal. Will eventually run out. Disadvantages: Produces greenhouse gases such as CO2 (Carbon Dioxide) Coal mines and Oil rigs are dangerous and harmful to the environment Advantages: Can be found in a lot of place in the world Easy to transport Cheap
6
Solar Energy (Renewable)
Energy generated using solar panels to convert light and heat into electricity. Disadvantages: Expensive to build solar stations Cloudy or night time there is no energy They are ugly Advantages: It’s free No greenhouse gases produced
7
Geothermal Energy (Renewable)
Energy from heat inside the Earth Disadvantages: Not very many places to build geothermal stations Harmful gases and materials sometimes come up. Advantages: It’s free No greenhouse gases produced
8
Biomass Energy (Renewable)
From plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil Disadvantages: Produces greenhouse gases such carbon dioxide There is not enough space to grow biomass fuel Advantages: It’s cheap and from things that we usually throw away Should not run out
9
Nuclear Energy (Nonrenewable)
Energy from heat produced when splitting a Uranium atom through a process called nuclear fission. Disadvantages: Waste is Radioactive Uranium will run out in about 50 years with our current use. Advantages: No harmful greenhouse gases A small amount of Uranium produces a lot of energy
