Nonrenewable resource: Any natural resource that exists in limited supply and cannot be replaced if used up.
Ex: oil and coal are nonrenewable recourses
Renewable resource: any natural resource that can replenish itself naturally over time.
Ex: water, soil and air are nonrenewable resources
Biomass: [renewable]- a biologic material derived from living or recent living things.
Geothermal: [renewable] - Thermal energy generated and stored in the earth.
Hydropower [renewable] - power derived from the energy of falling and running water.
Solar Energy [renewable] - Energy from the sun that is used to generate electricity.
Wind Energy [renewable] - using the mechanical energy of wind to generate electricity.
Petroleum [nonrenewable] - a liquid mixture containing hydrocalabrons that is present in some rocks.
Coal [nonrenewable] - a fossil fuel formed from the decompression of organic materials that have been subjected to heat and pressure for many years.
Natural Gas [nonrenewable] - flamable gas, concisting large amounts of methane and other hydrocarbons, occurring naturally underground.
Propane [nonrenewable] - a flamable hydrocarbon gas.
Uranium [nonrenewable] - a grey dence radioactive metal used as a fuel in nuclear reactors.

The 3 billion kWh of electricity produced by America's wind machines annually displace the energy equivalent of 6.4 million barrels of oil and avoid 1.67 million tons of carbon emissions, as well as sulfur and nitrogen oxide emissions that cause smog and acid rain. In other words, "more wind power means less smog, acid rain, and greenhouse gas emissions.
Go outside on a sunny day. The light falling on your face left the Sun just 8 minutes go. In that 8 minutes it traveled 93 million miles. Those photons are hauling and when they strike your PV module you can convert that motion to electricity. As technology, photovoltaics are not as glitzy as that new sport utility vehicle the television tells us to crave. But in many ways PV is a much more elegant and sophisticated technology
Petroleum is used so much that people will run out of it someday and people will be looking for it for so many years. Petroleum is used all over the world in cars and many other things. Petroleum is made up of hydrocarbons found in some rocks and is the most used resource in the world. Although petroleum is a nonrenewable it is still a great resource.
Advantages and Disadvantages to renewable and non renewable energy
Solar Advantages: Does not pollute air or water, and theres lots of places with sun
Solar Disadvantages: Only 15-20% efficient, costly to start up
Wind advantages: Does not pollute air or water, low cost
Wind disadvantages: Wind turbines can be noisy and ugly, can disrupt wildlife (birds and other animals).
Hydroelectric advantages: Does not pollute air or water, hydroelectric power plants are relatively inexpensive.
Hydroelectric disadvantages: Dams damage wildlife habitats, droughts can affect hydroelectric power plants.
Biomass advantages: Biofuels could replace petroleum (oil) in most vehicles.
Biomass disadvantages: Energy from fossil feuls is used to grow biomass.
Geothermal advantages: Does not pollute air, relatively inexpensive to make power plants.
Geothermal disadvantages: Makes ground unstable, some geothermal plants produce solid wastes that require careful disposal.
Fossil fuels advantages: Easy to transport, widely avaliable.
Fossil fuels disadvantages: Will get used up, causes pollution.
Nuclear Energy advantages: Nuclear power plants are relatively inexpensive to operate, does not cause pollution.
Nuclear Energy disadvantages: Produce radioactive waste that is difficult to store.
Disadvantages to Renewable energy: Not as effective as non-renewable energy, often depends on the weather. Advantages to Renewable energy: Does not pollute air,and can be replaced in a short period of time.
saving energy tips.
To save energy you need to turn off the lights and stop using energy that you don't need.Encourage everyone to keep the doors and windows closed when air condition is running.Create a "saving energy" sign to hang near your classroom light switches to remind people to turn lights off.
