Energy is an amount of the ability to do work, or of the work done. It does not have a time element. Power is the rate of expenditure of energy, it is an amount of energy per second, or other unit of time. In the SI system, energy is measured in Joules and power in Watts. In the footpound system often used in the US, but superseded by SI in most other places, energy is in units of ft.lbforce or BTU, whilst power is in horsepower.
In electrical engineering, power is in Watts or Kilowatts or Megawatts, to get an amount of energy over a period of time you generally introduce an hour as the unit, so that electrical energy is in kilowatt.hours, or other multiples depending on the application.

What are different ways of generating energy?
Solar power, wind power, tidal power, and fossil fuels are ways to get energy.
What different between power and energy?
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
What are different types of alternative energy sources?
Wind Power, Geothermal Energy, Hydroelectric Energy
Power is measured with what unit of energy?
Power and energy are different physical quantities. They have their own units in SI system Unit of energy is joule and that of power is watt. Of course electrical energy is measured as kW h
Is a nuclear power station an example of chemical energy?
No. Nuclear energy is a type of energy that is quite different from chemical energy.
What are three types of green energy?
Solar Power, Wind Power and Geothermal are three different types of green (renewable) energy.
Why is a power plant an example of nuclear energy?
There are different types of "power plant". Some run on nuclear energy, others don't.
How is solar power and wind power different?
solar power uses the sun's light for energy and wind power uses the wind to turn the turbines in windmills to create energy.
What is alternative enery?
A different source of energy such as methane wind power and hydroelectric power
How power plants work?
A power plant turns different types of fuels into other forms of energy. This energy powers the turbines. The turbines create the electricity. Different fuels make different kinds of electricity.
What are the different types of power?
hydroelectricity solar energy tidal power oil power wind power coal power nuclear power
What produces energy in a circuit?
Different energy sources can be used, for example a battery, or energy from plug (delivered by the power company).
