EnergyBy Jose Miguel Herrera and Jorge Salguero
What Is Energy?Energy is the capacitythat an object or bodyhas to transform a source of energy into work.The energy is measoured in Joules, (J) and KiloJoules (kJ). Heat is also measured in Calories,(cal) as Joules, calories have a larger Unit, KiloCalories, or Kcal.
Types of EnergyKinetic Energy: The energy that Objects have when they move.Potential energy: The energy that objects have when their equilibrium Point is moved.
Types of Energy (II)Electrical Energy: Its the energy Of an Electric CurrentElectromagnetic Energy: The energy of electromagnetic waves
Types Of Energy (III)Sound Energy: The sound waves which are transmitted through vibrationsChemical Energy: the energy asociated with Substances or atoms.
Types Of Energy (IV)Nuclear energy: Its contained in the nuclei of atoms.Its the vibration of particles in matter.
Energy SourcesEnergy Sources Is The Resource where we get the different types of energy. There are renewable and non-renewable. Both will be explained in the following slides.
Non-Renewable Energy SourcesThey are types of energy which will end, sooner or later. They were formed Many years ago, they are found deep underground and need special machinery to be extracted. They are explained In the next Slides.
Nuclear EnergyIt is stored in the nuclei of atomsIt is released by making the atoms crash each other by: Nuclear Fussion: 2 light nuclei for a bigger nucleus Nuclear Fission: One Big nucleus is split into 2
CoalIt was formed 300 Million years Ago, by the remains of plants and animals. Its extracted in 2 ways: Open-Cast Mines: When the coal is found near the surface Underground Mines: When the coal is found deep underground.
PetroleumIt was formed by the transformation of the organic remains of the earth, by the bacteria. It has lower density than water has.It is extracted by oil rigs, they use wells to find the petroleum and by pumps or natural force it gets pushed up to the surface. Then it gets purified, after that, an oil tanker carries it to its destination by sea.
Natural GasIts a mixture of gases formed by the decomposition of plants and animals. Its found in underground gas fields, usually you find petroleum near it.Its extracted by drilling.Its transported by transforming it into liquid and moving it through gas pipelines. Its destination is a Liquefaction plant.
Renewable energy Sources Now We Will explain several types of renewable energy sources. A renewableenergy source is a source which energy wontrun out, there are unlimited Resources for it.
Hydraulic The hydraulic energy is the type of Sourcethat produces energy from the water. It can be found in Hydroelectric dams. This energy is cheap, clean and it is not polluted, but building the dams is very expensive, and in case of breakage, there is a huge risk of catastrophe.
SolarThe solar energy is the source of energy thatuses the Sunlight to produce it. The Machine that helps us obtain & Transform the solar energy Are the solar panels. This energy isclean and unlimited, but its quite expensive.
WindThis energy has been always used for moving things, such as ships, Blades... The machine we use to produce this energyare Wind Turbines. This type of energy is Very Cheap, And unlimited.

GeothermalThis energy comes from the heat stored below the earth, such as geysers and volcanos. Depending on the temperature, we can produce heat or electricity
Biomass It is produced from organic matter waste and and plant remains. It is used in 2 ways: Toproduce electricity and to produce fuels, these are: charcoal, biogas, biodiesel and alcohol.
Municipal Solid Waste (M.S.W) This is the waste that we produce in ourhomes, demolition of buildings, etc. This is is what goes to the Landfield. Electrical and Thermal energy is produced through the incineration of these wastes.
Types of power Stations In the following slides we will explain thetypes of power Stations that operate allover the world these days. A Power station isusually a building which its only objective is to produce energy.
Nuclear power plant A nuclear power plant is the place where the nuclear energy is extracted. In it, the heatsource is One or more chemical reactors. The heat produced by them is them moved to a Boiler which rotates a generator to produce electric current.
Oil rigAn oil rig is the place where oil gets extracted. It is usually in the sea. It works with a drill which is mined deep underground, near the oil. When it reaches the oil, the drill is pulled up and the oil rises by pressure, or by action of pumps
Natural gas Power Plant It is extracted the same way as petroleum, infact, when you look for petroleum, you usually find natural gas over it. A drill is minedunderground until it reaches natural gas, then by pressure or the force of a pump, The gas pulls up.
Solar power plant A solar power plant is the place where solar panels are grouped to produce energy. They have photovoltaic cells which catch the sunenergy and transform it into heat or electricity.
Eolic power plant An eolic power plant is a group of windturbines which produce energy from the wind.They Are usually on Windy places like Valleys. The wind moves the blades of the turbine which rotate a generator.
Municipal Solid Waste Plant This is the place where our Daily Trash is incinerated to produce electrical or eitherthermal energy. The incineration temperaturesshould always be over 900ºC and Filters would be used to prevent the release of toxic substances to the atmopsphere.
Wind Turbine creates Water From Thin Air – Our Oppinion. When we first readed it, it looked likesomething by which you think: How Come this can be done? But as we scrolled down we noticed that the procedure is actually quiteeasy. Just pick air, extract the humidity, cool it down and you got water. Simple as that. ↓
Would this help underdeveloped countries? We think it will. Just get someone nice to donate the 500k€ it costs and You got water for like 3-4 african villages. We think that if you made a NGO (Non-Gubernamental organisation) you could quickly get some ofthese installed in africa. For like 20€ per family and month, 500 members, you get 10000€ per month, you can get the money for one in like 2.5 years. Easy. The thing that really impressed us is that it can produce 1000l of water a day. One THOUSAND litres of water?thats a lot. Overall, amazing idea. We liked it a lot
