Photovoltaic power plant
Renewable:
• Abundant and inexhaustible
Non-renewable:
• May or may not be abundant
• Depleted when we use them up
• Cannot be renewed in a short penod of time~
Primary:
• Obtained directly from nature
• Examples, crude oil, natural gas, coal, nuclear energy
and renewable energies
Secondary:
• Resulting from transformation of pnmary sources
• Examples; electnaty, some petroleum denvatives
Conventional:
• Most commonly used in mdustrialised countnes
• Example energy that comes from fossil fuels
Non-conventional
• Alternauve energy sources
• In early stages of their technological development
• Solar and wind power belong to this group
• Low environmental impact
• Don't generate by-products that pollute the
environment
Pollutants:
• Sources that have negative effects on the environment,
for example, they might generate by-products that severely pollute the enviroment

Electric power plants
Electric power plants are facilities where pnmary or secondary energy is transformed into electnmty, Once electricity is generated, it must be transported to towns, cities or industrial parks.
Transport and distribution of electrical energyElectric power plants are usually located far away from the points where the energy is used — fur safety reasons, space requirements or physical and geographical considerations
3.2. Fossil fuel thermal power plants At this type of power plant, water is heated in a boiler by the heat
generated from the combustion of a fossil fuel, usually natural gas or coal
The steam that's generated moves the turbine connected to the generator
3.3. Hydroelectric power plants
This type of power plant uses the potential energy provided by the
height of the stored water in a dam, converting it mto kinetic energy.
Tlus energy moves the blades of the turbine
Depending on the destination of the water, hydraulic power plants are
divided into two types, gravity or pump.
3.1. Nuclear power plants
This type of plant tm.ludes a nuclear fission reactor that produr.es the
pressunsed steam needed to move the turbme rotor Uranium ts the main fuel used
Wind power plants and wind farms
Geothermal power plants
Biomass thermal power plants
Ocean power plants
