Photovoltaic cell
A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
Wind turbine
a device that converts kinetic energy from the wind, also called wind energy, into mechanical energy; a process known as wind power.
Wind energy
form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.
Watt
is a derived unit of power in the International System of Units (SI). Defined as one joule per second, measures the rate of energy conversion or transfer
Wind farm
is a group of wind turbines in the same location used to produce electric power.
Power grid
is an interconnected network for delivering electricity from suppliers to consumers. It consists of three main components: 1) power stations that produce electricity from combustible fuels (coal, natural gas, biomass) or non-combustible fuels (wind, solar, nuclear, hydro power); 2) transmission lines that carry electricity from power plants to demand centers; and 3) transformers that reduce voltage so distribution lines carry power for final delivery.
Renewable energy
is energy which comes from natural resources such as sunlight, wind, rain, tides, waves and geothermal heat, which are renewable
Potential energy
is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system. The SI unit for measuring work and energy is the joule.
Power
is the rate at which energy is transferred, used, or transformed.
Sustainable
is the sustainable provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs.
Solar energy
radiant light and heat from the sun.
Work
the work done by, or energy transferred by, a force acting through a distance
