forms of energy
potential
potential energy is stored energy or gravitational energy
kinetic
forms of energy: kinetic
kinetic energy is motion-the motion of waves,electrons,atoms,molecules,substances,and object and example is: electrical energy
law of conservation:
the law of conservation of energy says it is neither created nor destroyed. when we use energy we do not waste it we simply change it's form.
efficiency:
efficiency:
most thermal power plants are about 35 percent efficient of the 100 units of energy that go into a plant,65 units are lost as one form of energy
sources of energy:
non renewable
these energy sources are called non renewable because they cannot be replenished in a short period of time
renewable
they are called renewable energy sources because they can be replenished in a short period of time
secondary energy:
Secondary energy refers to the more convenient forms of energy which are transformed from other, primary, energy sources through energy conversion processes. ... The two most well-known energy carriers are: Electricity. Hydrogen
energy consumption:
energy cosumption is the amount of power used
measuring with Btu's
btu is a measure of quantite of heat defined since 1956
it is measured using a british thermal unit thermometer
users
electric power
the electric power sector includes generation facilities and power plants
transportation

energy prices information
There were a series of energy crises between 1967 and 1979 caused by problems in the Middle East but the most significant started in 1973 when Arab oil producers imposed an embargo.
