Fossil Fuels
They are formed from the decaying remains of ancient plants and animals.
What is fossil fuels?
This uses the energy from controlled nuclear reactions to generate electricity:
Nuclear reactor
Converts radiant energy from the Sun directly into electrical energy
Photovoltaic Cell
Solar cells would be more practical to use if they were what
A. pollution free B. nonrenewable
C. less expensive D. larger
C. Less expensive
Used to separate the many different compounds found in petroleum
What is fractional distillation/boiling?
Special caution should be taken in disposing of
Nuclear waste
Energy from water is
Hydroelectricity
What do hydrocarbons react with when fossil fuels are burned?
Oxygen
Two other uses of Petroleum are:
Plastics, Synthetic Fabrics, Lubricants, and Asphalt
Low level nuclear wastes usually contain only a small amount of radioactive material with short half-lives. High level nuclear wastes are usually highly radioactive and contain material with long half-lives
What is the difference between low-level and high-level nuclear wastes?
Makes use of thermal energy inside the earth
Geothermal energy
Why are fossil fuels considered to be nonrenewable resources?
They aren't being produced as fast as they're being used.
The most abundant fossil fuel is:
Coal
What is the major disadvantage of using nuclear fusion reactors?
extremely high temperatures required

A. steam B. carbon dioxide
C. plutonium D. water
Steam

85%
List the form of fossil fuels:
Petroleum, natural gas, and coal
The sun gives off a tremendous amount of energy through a process called
thermonuclear fusion
What is the source of almost all of Earth's energy resources?
The Sun
How are spent nuclear fuel rods usually disposed of?
Storing them in a deep pool of water
