|
Two types of energy.
|
Potential and Kinetic
|
|
Kinetic Energy
|
The energy associated with a moving object, for example, a moving football, a speeding train, a waterfall or a rock falling from a cliff.
|
|
Potential Energy
|
The energy in an object due to its position or the arrangement of its parts. It includes gravitational, elastic, chemical and electromagnetic potential energy.
|
|
Gravitational potential energy
|
Produced when an object is lifted up and work is done against the force of gravity.
|
|
Elastic potential energy
|
Produced when an object (such as a spring or a rubber band) resists being stretched out of shape.
|
|
Chemical potential energy
|
The energy that holds molecules together.
|
|
Electromagnetic potential energy
|
Stored in a battery or supplied from a power plant, hydroelectric dam or windmill.
|
|
Thermal energy
|
The movement of molecules that make up the object.
|
|
Main forms of non-renewable energy sources.
|
Coal, oil, timber and gas.
|
|
Main effect of carbon dioxide emissions from the large-scale burning of fossil fuels.
|
Enhanced greenhouse effect leads to higher mean global temperatures, sea-level rise and general climate changes.
|
|
Main forms of renewable energy sources.
|
Wind, solar, tidal, wave, hydroelectric and biomass.
|
|
Advantages of nuclear power.
|
Very low CO2 emissions, high energy density
|
|
Disadvantages of nuclear power.
|
Safety issues, high cost of decommissioning, possible radioactive contamination, waste product storage problems, and link with nuclear weapons.
|
|
Advantages of Solar energy
|
Clean energy
A completely renewable resource Make absolutely no noise at all Very little maintenance |
|
Disadvantages of Solar Energy
|
Set-up costs
Continuity of supply. |
