Energy is the capacity to do work. Mainly energy is of two types:- Conventional sources of energy Non-conventional types of energy. EnergySlide 4: Energy Conventional sources of energy Non-conventional sources of energy Coal Oil and Natural Gas Nuclear energy Hydel energy Solar energy Ocean energy biogas Wind energy Geothermal energy Fossil FuelsDISTRIBUTION OF TYPES OF ENERGY: DISTRIBUTION OF TYPES OF ENERGY HMMMM....: HMMMM.... What do you think nonrenewable resources are? Break it down... Nonrenewable? Resource?Conventional sources: Conventional sources A conventional source of energy cannot be re-made or re-grown at a scale comparable to its consumption.Various forms of conventional sources of energy are:-: Various forms of conventional sources of energy are:- Nuclear energy Fossil Fuels like -petroleum -Coal -Natural gas Electrical EnergyFossil Fuels: Fossil Fuels Fossil fuels include coal, natural gas, petroleum, shale oil, and bitumen. They all contain carbon and were formed as a result of geologic processes from the remains of organic matter produced by photosynthesis hundreds of millions of years ago.Slide 11: All fossil fuels can be burned with air or with oxygen derived from the air to provide heat. This heat may be employed directly, as in the case of a home furnace, or utilized to produce steam with which to drive a turbo generator so that it can supply electricity. It serve to increase both the pressure and the temperature of the combustion products to furnish motive power.What Are the Advantages and Disadvantages of Fossil Fuels?: What Are the Advantages and Disadvantages of Fossil Fuels? Oil, natural gas, and coal are currently abundant and relatively inexpensive, but using them causes air and water pollution, degrades large areas of land, and releases greenhouse gases to the atmosphere.Disadvantages of burning fossils fuels : Disadvantages of burning fossils fuels It causes air pollution The oxides of carbon, nitrogen, sulphur in the form of So x and No x are released in nature which are acidic oxides that lead to acid rain polluting air, water and soil. Greenhouse gases like CO 2 are also released in the atmosphere causing global warming.Natural Gas Is a Useful and Clean-burning Fossil Fuel: Natural Gas Is a Useful and Clean-burning Fossil Fuel Natural gas Conventional natural gas Unconventional natural gas Liquefied petroleum gas (LPG) Less carbon dioxide emitted per unit of energy than with crude oil, tar sand, shale oilNatural Gas Is a Useful and Clean-burning Fossil Fuel: Natural Gas Is a Useful and Clean-burning Fossil Fuel Compressed natural gas (CNG) World supply of conventional natural gas – 62-125 years Unconventional natural gas Coal-bed methane gas Methane hydrateCOAL, PETROLEUM, AND GAS: COAL, PETROLEUM, AND GAS Coal , is considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.HOW IS COAL MADE ???: HOW IS COAL MADE ???Coal Is a Plentiful But Dirty Fuel: Coal Is a Plentiful But Dirty Fuel Used in electricity production World’s most abundant fossil fuel Sulphur and particulate pollutants Mercury and radioactive pollutants Heavy carbon dioxide emissions Pollution control and environmental costs China major builder of coal plantsSlide 22: Heat produced by burning pulverized coal in a furnace boils water to produce steam that spins a turbine to produce electricity. The steam is cooled, condensed, and returned to the boiler for reuse. Waste heat can be transferred to the atmosphere or to a nearby source of water. The largest coal-burning power plant in the United States, located in Indiana, burns three 100-car trainloads of coal per day Coal-burning power plant.HOW ARE OIL AND GAS MADE ???: HOW ARE OIL AND GAS MADE ??? NUCLEAR ENERGY: NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!What Are the Advantages and Disadvantages of Nuclear Energy?: What Are the Advantages and Disadvantages of Nuclear Energy? The nuclear power fuel cycle has a low environmental impact and a very low accident risk, but its use has been limited because of high costs, a low net energy yield, long-lived radioactive wastes, vulnerability to sabotage, and the potential for spreading nuclear weapons technology.How Does a Nuclear Fission Reactor Work?: How Does a Nuclear Fission Reactor Work? Nuclear fission Light-water reactors Boil water to produce steam to turn turbines to generate electricity Radioactive uranium as fuel Control rods, coolant, and containment vesselsSlide 35: Three-Mile Island, PennsylvaniaDealing with Radioactive Wastes: Dealing with Radioactive Wastes High-level radioactive wastes Long-term storage: 10,000–240,000 years Deep burial Toxic wastesSafety and Radioactive Wastes: Safety and Radioactive Wastes On-site storage of radioactive wastes Safety features of nuclear power plants Nuclear fuel cycle Reactor life cycle Large amounts of very radioactive wastesSlide 42: A 1,000-megawatt nuclear plant is refueled once a year, whereas a coal plant of the same size requires 80 rail cars of coal a dayNON-CONVENTIONAL SOURCES OF ENERGY: NON-CONVENTIONAL SOURCES OF ENERGY Resources that are found unlimited in the nature and can be replenished easily in a small period of time are called non-conventional sources of energyVarious types of non-conventional energy sources are:-: Various types of non-conventional energy sources are:- Hydel Energy Solar energy Ocean Energy Geothermal Energy Wind Energy Bio-gasWhat Are Advantages/Disadvantages of Non-conventional Energy Resources?: What Are Advantages/Disadvantages of Non-conventional Energy Resources? Using a mix of renewable energy sources – especially sunlight, wind, flowing water, sustainable biomass, and geothermal energy – can drastically reduce pollution, greenhouse gas emissions, and biodiversity losses and can be replenished easily.Slide 46: Energy FroM WINDSPRODUCTION OF ELECTRICITY FROM WINDS : PRODUCTION OF ELECTRICITY FROM WINDS Due to unequal heating of land masses and water bodies by solar radiation, air is generated that causes winds to blow the kinetic energy of wind is utilised to run the wind mill blades which is supported by a turbine which rotates to generate electricity. Minimum speed required to turn the blades of the windmill is around 15km/hrSlide 54: Geothermal EnergyEnergy by Tapping the Earth’s Internal Heat: Energy by Tapping the Earth’s Internal Heat Geothermal energy Geothermal heat pumps Hydrothermal reservoirs Steam Hot water Deep geothermal energyGEOTHERMAL POWER PLANT: GEOTHERMAL POWER PLANTSlide 61: Hydel EnergyProducing Electricity from Flowing Water: Producing Electricity from Flowing Water Hydropower Leading renewable energy source Much unused capacity Dams and reservoirs Turbines generate electricity Eventually fill with silt Hydro generatorsProduction Of Hydel Electricity : Production Of Hydel Electricity The water flowing in the river is collected in the dam which is allowed to fall from the top of the dam with water turbines located near the bottom of the dam. The kinetic energy of the flowing water gets transformed into potential energy and the movement of the water turbines generate electricity. Solar energy is the ultimate source of all types of energies.
