RENEWABLE ENERGIES
WATER (HYDROELECTRIC)
Energy taken from water (converted to electricity)
Dams (dighe) contains water
Water flowing through turbines and the energy is captured to run generators
TIDAL (marea):
ocean or sea create energy, but the costs are too much
EARTH HEAT (GEOTHERMAL)
Magma heated water underground
The steam spins a turbine, connected to a generator, creating electricity.
we also have GEYSERS
locations: Yellowstone National Park (USA) - Iceland - New Zealand.
WIND
Wind generates power to generate electricity.
turbines, or «windmills»
Advantages
CLEAN ENERGY / FAST ISTALLATION
Disadvantages
NOT CONSTANT / NEED A LOT OF SPACE
SUN
powerful source for the future
Solar cells are called photovoltaic cells or modules (material used is SILICON)
Light hits the cell, transferring energy to it. This energy release allows electrons to move, creating an electric current.
