Dead plant material accumulates and over time heat and pressure create lignite coal.
Oil and Natural Gas is made from the burial of marine organisms.
Possible advantages: generate electricity, makes plastics, home shingles, heat buildings. Some Disadvantages: create pollution, they are nonrenewable
Sedimentary Rocks
They are called fossil fuels because they are made up of the remains of animals and plants.
nonrenewable
renewable
10,000 yrs
Because heat released in nuclear reactors produce steam, which is used to produce electricity.
Nuclear fusion is when materials of low mass are fused together to form a substance of higher mass (energy from the sun). Nuclear fission is the splitting of heavy elements (like uranium) to produce energy.
Solar cells actively collect energy from the sun and transforms it into electricity.
Solar cells work less efficiently on cloudy days and cannot work at all at night.
Wind is nonpolluting and it's free.
Wind is unpredictable. For an area to use wind energy consistently, the area must have a persistent wind that blows steadily.
A large concrete dam is built to retain water. As water is released, its force turns turines at the base of the dame. The turbines then turn generators that make electricity.
Geothermal Energy
The hot, dry underground rocks used can be found just about anywhere.
Energy resources that can be replaced in nature or by humans within a relatively short period of time.
about 90%
As one tree is cut down, another can be planted in its place.
energy used from burning organic material such as wood, alcohol, and garbage.
gases and small particles are released and can pollute the air.
As much as 2/3 of what we throw away can be burned.
It is cheap and helps reduce the amount of material to be dumped in a landfill.
Burning municipal waste can produce toxic ash residue and air pollution.
