Presentation on theme: "Nonrenewable Resources"— Presentation transcript:
1 Nonrenewable Resources Resources that cannot be replaced in our lifetime and will eventually run out.
2 Renewable ResourcesResources 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 windYou need a lot of turbines to make electricityThey are uglyAdvantages:It’s freeNo greenhouse gases produced
4 Hydropower (Renewable) Energy generated by tides, waves, and dams.Disadvantages:Dams are expensiveAffects nearby wildlifeNo rain = no electricityAdvantages:It’s freeNo 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 environmentAdvantages:Can be found in a lot of place in the worldEasy to transportCheap
6 Solar Energy (Renewable) Energy generated using solar panels to convert light and heat into electricity.Disadvantages:Expensive to build solar stationsCloudy or night time there is no energyThey are uglyAdvantages:It’s freeNo greenhouse gases produced
7 Geothermal Energy (Renewable) Energy from heat inside the EarthDisadvantages:Not very many places to build geothermal stationsHarmful gases and materials sometimes come up.Advantages:It’s freeNo greenhouse gases produced
8 Biomass Energy (Renewable) From plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oilDisadvantages:Produces greenhouse gases such carbon dioxideThere is not enough space to grow biomass fuelAdvantages:It’s cheap and from things that we usually throw awayShould 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 RadioactiveUranium will run out in about 50 years with our current use.Advantages:No harmful greenhouse gasesA small amount of Uranium produces a lot of energy
