Study Notes

Energy is defined as the ability to do work and can be transferred or converted into different forms.
The sun is the source of energy for life on Earth and releases thermal, heat, and radiant energy.
Internal combustion engines use the theory of thermodynamics to generate power.
Torque is the rotating force that may or may not result in motion, measured as the amount of force multiplied by the length of the lever through which it acts.
Work is defined as actually accomplishing movement when force (torque) is applied to an object.
Power is defined as the rate of doing work or the rate at which work is being done.
Electrical power is the rate at which electrical energy is transferred by an electric circuit, usually produced by electric AC generators.
Kilowatt-hour (kWh) is a unit of energy, and kilowatt (kW) is a measure of power.
Photovoltaics (PV) is the direct conversion of light into electricity at the atomic level, using semiconductor materials like silicon to form an electric field.
Solar energy used to generate electricity is a promising form of renewable energy.

The photoelectric effect was discovered by Edmond Becquerel in 1839.
Albert Einstein described the nature of light and the photoelectric effect, winning a Nobel Prize in physics in 1905.
Bell Laboratories developed the first photovoltaic module in 1954.
Wind power is a renewable energy source that generates electricity using wind turbines.
Hydroelectricity is generated by converting the energy of flowing water into mechanical energy to turn a hydroelectric generator.
Hydroelectricity is relatively cheap to produce and has a lower output level of greenhouse gases than fossil fuel-powered electricity plants.
Geothermal energy is derived from the heat of the earth and can be used to produce electricity using a geothermal power plant.
Geothermal power is renewable and cost-effective, but historically limited to areas near tectonic plate boundaries.
A geothermal heat pump system can be used to warm or cool the interior of a building using the constant temperature of the ground.
The term "work" in physics was introduced by Gaspard-Gustave Coriolis in 1826.
