Energy can’t be made or destroyed, regarding motion , there are kinetic and potential energy. Regarding power , there are two main kinds of energy 1. Renewable energy 2. Nonrenewable energyClassification of Renewable energy: Classification of Renewable energy Bioenergy Geothermal Wind Solar Hydrogen Tidal And many more...Solar energy: Solar energy Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy , can be used directly for heating and lighting homes and other buildings, for generating electricity. Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy . About half of the radiation is in the visible. Solar technologies are generally classified as Active and Passive solar energyDefinition of photovoltaic Photo = “light” and photons = “energy” particles coming from sunlight; voltaic = producing a voltage or volts. : Definition of photovoltaic Photo = “light” and photons = “energy” particles coming from sunlight; v oltaic = producing a voltage or volts.Photovoltaic (PV) Effect: Photovoltaic (PV) Effect When sunlight is absorbed by the materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity . Several connected PV arrays can provide enough power for a household; for large electric utility or industrial applications, hundreds of arrays can be interconnected to form a single, large PV system.PowerPoint Presentation: PHOTOVOLTAIC SOLAR PANALS It convert sunlight directly into electricity. It consists of several connected 0.6-V dc PV cells, which are made out of a semiconducting material sandwiched between two metallic electrodes. The photovoltaic effect refers to the separation of minority carriers [electrons and holes] by a built-in electric field, such as a PN-junction or Schottky barrier. Thin-film crystalline-silicon solar cells consist of layers about 10 µm thick compared with 200- to 300- µ m layers for crystalline-silicon cells.Thin film technology: Thin film technology Thin-film crystalline-silicon solar cells consist of layers about 10 µm thick compared with 200- to 300- µ m layers for crystalline-silicon cells. Advanced Energy provides highly reliable power conversion and control solutions to thin films manufacturing companies around the world.PowerPoint Presentation: Copper and indium are deposited by magnetron sputtering, followed by selenization to form the high-absorbing ptype semiconductor cuinse 2 , which is combined with an n-type electrode of zno to create thin-film solar modules A =Barrier/Mo deposition B = Laser patterning C =Cu/In/Se deposition D =Heat treatment 500°C E =Chemical deposition 60°C F =Patterning G =2nd deposition 200°C H =Patterning I =Contacts/laminationWind power: Wind power It converting wind energy into electricity by using wind turbines. Wind comes from atmospheric changes ; changes in temperature and pressure makes the air move around the surface of the earth. A wind turbine captures the wind to produce energy. It create power without using fossil fuels, without producing greenhouse gases or radioactive or toxic waste. Wind power is one of the best ways to combat global warming.Nuclear Energy: Nuclear Energy It is produced by a nuclear reaction when the splitting or fusion of atoms occurs. Nuclear fuel does not produce greenhouse gases, so will not contribute to global warming. There is a relatively long-lasting supply of raw material. The main issues that come up with nuclear energy are the safety standards of a nuclear power plant and the storage of its radioactive waste. France is the world leader in nuclear energy production, relying on nuclear power for 80% of its electricity.Free Energy/Radiant Energy: Free Energy/Radiant Energy It is the energy of electromagnetic waves . The oceans and other waters of the world cover over 70% of the Earth’s surface. Free Energy device/method would draw additional power from the sea of Universal Energy in which all matter is carried, and it is thought that such a device would produce more energy than is used to run it, also known as Over unity. Constantly moving, which allows many waters to provide hydroelectricity , but they are also soaking up the warmth of the sun. This warmth is able to be turned into electricity as well, using a technology called ocean thermal energy conversion.SQUIDS/OCEAN RADIENT ENERGY: SQUIDS/OCEAN RADIENT ENERGY It has an inflatable absorber similar to a large balloon which fills with sea water. Sitting just under the surface, the absorber is moved by passing waves and the energy from this motion drives a generator to produce electricity. Scotland's leading marine energy test centre has opened its doors to a new generation of developers to test prototype machines, one of which is aiming to harness wave energy using a design based on the humble squid.MEMS & Nanotechnology: MEMS & Nanotechnology Ultra low power electronics – MCUs, RTCs, DSPs Smart devices in everything, Sensors everywhere for data capture and analysis, Wireless is pervasive, Miniaturization, Integration, High Reliability, Eco-friendly solutions, Renewable energy sources, Reduced life cycle costs.PowerPoint Presentation: ELECTRONIC APPLICATIONSGood Materials: Good Materials BAMBOO CORK COCONUTRenewable energy from natural resources: Renewable energy from natural resources Synthetic solar cells created on tobacco plants Generating energy from evaporation on a leaf Electricity from bacteria and grass clippings Generating energy from trees to power sensors Virus Battery Energy from Cactus Living Batteries Frog-inspired technology to generate biofuel using artificial photosynthesis Harvesting energy from Spinach Energy to run LEDs harvested from treesAdvantages & disadvantages of nuclear energy: Advantages & disadvantages of nuclear energy Advantages Disadvantages Nuclear power costs about the same as coal, so it's not expensive to make. Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Produces huge amounts of energy from small amounts of fuel. Produces small amounts of waste. Nuclear power is reliable. It is very, very dangerous. It must be sealed up and buried for many thousands of years to allow the radioactivity to die away. For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong. In 2005 it was the second slowest_growingAdvantages and Disadvantages of Non-renewable Resources: Advantages and Disadvantages of Non-renewable Resources ADVANTAGES It provide United States with electricity, gasoline and heat in the future. Oil, petroleum, natural gas, coal and uranium, are some of the primary sources of fuel used to provide power and heat to many industrial, commercial and residential consumers DISADVANTAGES Limited sources of energyPowerPoint Presentation: Saving Energy Saving Money Saving the Environment Quality Excellence Reliability Range Support and Service Cost-effective Efficient Clean and sustainableCONTROLLERS AND REGULATORS: CONTROLLERS AND REGULATORS SOLAR CHARGE WIND TURBINEPowerPoint Presentation: Renewable energy technologies can help contribute to a clean and secure energy future for our nation and the world As an electricity provider As a farmer or rancher As a homeowner As a small business ownerConclusion Energy improves the quality of our life. Its use also causes demages to our earth. We have to make a balance between energy consumption and environment protection. We have to make more efforts to ensure that the world’s resources are to be used in a sustainable energy.: Conclusion Energy improves the quality of our life.
