    Renewable energy and resources Renewable energy and resources Presentation Transcript

    • V.REVATHIAMBIKASAMS College of Engg & Tech., Chennai.
    • INTRODUCTION Energy is the power to do works and drive machines. 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 energy
    • Classification of Renewable energy Bioenergy Geothermal Wind Solar Hydrogen Tidal And many more...
    • 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 energy
    • Definition of photovoltaicPhoto = “light” and photons = “energy” particles coming from sunlight;voltaic = producing a voltage or volts.
    • 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.
    • 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-µm layers for crystalline-silicon cells.
    • Thin film technology  Thin-film crystalline-silicon solar cells consist of layers about 10 µm thick compared with 200- to 300-µm layers for crystalline-silicon cells.  Advanced Energy provides highly reliable power conversion and control solutions to thin films manufacturing companies around the world.
    • Copper and indium are deposited by magnetron sputtering, followed by selenization to form the high-absorbing ptype semiconductor cuinse2, 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/lamination
    • 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 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
    • 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
    • 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. Scotlands leading marine energy test centre has opened
    • 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.
    • Good MaterialsBAMBOO CORK COCONUT
    • 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 trees
    • Advantages & disadvantages of nuclear energy Advantages Disadvantages Nuclear power costs  It is very, very dangerous. about the same as coal,  It must be sealed up and so its not expensive to buried for many make. thousands of years to Does not produce smoke allow the radioactivity to or carbon dioxide, so it die away. does not contribute to  For all that time it must the greenhouse effect. be kept safe from Produces huge amounts earthquakes, flooding, of energy from small terrorists and everything else.
    • Advantages and Disadvantages of Non-renewable ResourcesADVANTAGES 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 consumersDISADVANTAGES Limited sources of energy

    • 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 owner
    • our earth.We have to make a balancebetween energy consumption andenvironment protection.We have to make more efforts toensure that the world’s resourcesare to be used in a sustainableenergy.
