Energy resources
Biofuels
-
Production
Wood, plants and other vegetations is send to a plant that extract the biofuel and mix it with chemestry and creates fuels
-
Nuclear
Production
Nuclear energy is produce by the slip of the nucleous of a atom by nuclear fission that release energy from the atom nucleous. This foul comes from uranium pellets that are splitted and this production of energy comes with heat that is cool down with water
Disadvanteges
-
-
Radioactive waste, dangerous and expensive
-
Wave
-
Advantages
Predictable, friendly to the environment and more reliable than tidal energy.
Disadvantages
Exclusivity to oceans, can only work in a big ocean.
More expensive to transport to places far away from the shore
Hydro
Advantages
Renewable, clean energy source, available to most countries.
Disadvantages
Unreliable, dependent on the climate and the water levels, can cause droughts downstream.
-
Fossil fuels, gas, oil coal
Disadvanteges
-
-
Extraction and consumption of this fuels creates C02 and damages the ozone layer and is one of the main causes of global warming
Porduction
Fossil fuels are produced by the pression of the diferent layers of the earth creating preasure on the fossil of the previous remant of vegetation. This fossils can be extracted by several way.
-
Tidal
-
Advantages
Easy to implement, inexpensive, natural, does not produce greenhouse gasses.
-
Wind Energy
-
-
The wind blows the blades of the turbine, which are attached to a rotor. The rotor then spins a generator to create electricity.The blades are positioned so that they face directly into the wind. VAWTs have shorter, wider curved blades that resemble the beaters used in an electric mixer.Once the electricity is generated, it can be used, connected to the electrical grid, or stored for future use.
Solar
-
A solar thermal system generates electricity indirectly by capturing the heat of the sun to produce steam, which runs a turbine that produces electricity.
A solar photovoltaic system produces electricity directly from the sun’s light through a series of physical and chemical reactions known as the photovoltaic effect.
Geothermal
Cold water is pumped at high pressure into an injection well. allowing the water to seep sideways through the hot rock.Several ‘production wells’ are also drilled nearby to allow the heated water to flow back out of the rock.At the surface, the hot water is passed through a heat exchanger to boil a secondary fluid, which creates high pressure gas to drive a turbine, generating electricity
