● Enegy definition● Types of energy● Energy sources● Renewable energy● Non renewable energy● Enviromental inpact● Energy power stations

Page 3: Tecnologia 2

The term energy has various definitions, related to the idea of a capacity to act, transform or put in motion a object

Page 4: Tecnologia 2

● Hydraulic energy● Solar enegy● Wind energy● Marine energy● Geothermal energy● Biomass● Municipal solid waste

Page 5: Tecnologia 2

Mechanical energy produced by the movement of the water

Energy take from the sun using solar panels

Energy take from the wind using wind turbines

Page 6: Tecnologia 2

Can produced three types of energy:Tidal energy;extracted from the tidesWave energy,obtained from the movement of the sea wavesOcean thermal energyproduced from the differenceTemperatures between the surface of the sea and the deep sea

Energy come from the heat stored in the earth ´s crust,sometimes appears naturally,for example,geysers and volcanic eruptions.Temperature -150ºC heat can be producedTemperature +150ºC electricity can be produced

Page 7: Tecnologia 2

Produced from plant remains,forest and agricultural waste,high-energy plantsThis can produced electricity and for trnsformation into charcoal,biogas,biodiesel,and alcohol

This is produced from dom,estic activitioes in privatespublic buildings,demolition or renovation of houses...The incineration of this wastes can produced electrical or thermal energy

● Nuclear energy● Coal● Petroleum● Natural gas

Page 9: Tecnologia 2

Is stored in the nuclei of atoms and are released in the nuclear.Reaction that occurs in certain atoms.Are two types:Nuclear fusion and Nuclear fission

It is a sedimentary black rock, very rich in carbon and used as a fossil fuel.

Page 10: Tecnologia 2

Formed from the buried remains of plants and animals thatHave decomposed because of bacterial action.Is found in porous rocks under the sea and in other Sedementary bassins,forming oil fields

Mixture of gases from decomposed plants and animals.Is found in underground gas fields and in porous rocks

The environmental impact is the effect of a certain action on the environment in its various aspects. The concept can be extended, with little use for the purposes of a natural catastrophe.

The main causes of the negative effects in the environment are caused by the humans and some tipes of produce energy.

● Mechanical energy● Thermal energy● Electrical energy● Electromagnetic energy● Sound energy● Chemical energy● Nuclear energy

It is the energy in charge of the movement. There are two different types of mechanical energy:- kinetic energy is responsable of any body that move. For example when we move our hand.- potencial energy: a body is subjected to potencial energy when it is above the soil. For example a book on a table have potencial energy.A plane is a good example of both kinetic and potencial energy.

This type of energy measured the heat or the increase of the temperature.

This type of energy is associated whith an electirc current and if the body is conected to a supply of energy this body transform the power into work.

Page 15: Tecnologia 2

Sound energy is the form of energy associated with the vibration of a matter.

The electromagnetic energy is the energy that comes from electromagnetic radiation. This radiation is composed of waves, such as radio waves

Page 16: Tecnologia 2

Chemical energy is a chemical substance to undergo a transformation through a chemical reaction or, to transformother chemical substances

Nuclear energy usually means the part of the energy of an atomic nucleus, which can be released by fusion or fission

Page 17: Tecnologia 2

Energy power stations are a generator of energy, a machine that rotate transforming mechanical power into electrical power by creating relative motion between a magnetic field and a conductor.

Wind turbines haved long produced renewable energy but from now can also produced Eole water said a French engineeringHe explains that the technology works by first generating electricity in the traditional manner of a wind turbine. The next stage sees air sucked in through the nose of the turbine via a device known as an "air blower".All air trapped directed through an electric cooling compressor situated behind the propellers. This extracts humidity from the air, creating moisture which is condensed and collected.The water gathered is then transferred down a series of stainless steel pipes, and caried to atank in the base of the turbine.Once there, the water is filtered and purified before it is ready for use and consumption.One turbine can produce up to 1,000 liters of water every day, depending on the level of humidity, temperature and wind.I think that this is a very good idea because can obtain water from more placed not only from the rain
