Alternative energy is an umbrella term that refers to anysource of usable energy intended to replace fuel sourceswithout the undesired consequences of the replacedfuels.[1] The term "alternative" presupposes a set of undesirableenergy technologies against which "alternative energies"are contrasted. As such, the list of energy technologiesexcluded is an indicator of which problems the alternativetechnologies are intended to address. Controversiesregarding dominant sources of energy and theiralternatives have a long history. The nature of what wasregarded alternative energy sources has changedconsiderably over time, and today, because of the varietyof energy choices and differing goals of their advocates,defining some energy types as "alternative" is highlycontroversial. 17. Solar energy, radiant light and heat from the sun, has beenharnessed by humans since ancient times using a range ofever-evolving technologies. Solar radiation, along withsecondary solar-powered resources such as wind and wavepower, hydroelectricity and biomass, account for most of theavailable renewable energy on earth. Only a minusculefraction of the available solar energy is used.Solar powered electrical generation relies on heat engines andphotovoltaics. Solar energy's uses are limited only by humaningenuity. A partial list of solar applications includes spaceheating and cooling through solar architecture, potable watervia distillation and disinfection, daylighting, solar hot water,solar cooking, and high temperature process heat for industrialpurposes.To harvest the solar energy, the most common wayis to use solar panels. 18. Geothermal energy is thermal energy generated and stored in theEarth. Thermal energy is energy that determines the temperature ofmatter. Earth's geothermal energy originates from the originalformation of the planet, from radioactive decay of minerals, fromvolcanic activity, and from solar energy absorbed at the surface. Thegeothermal gradient, which is the difference in temperature betweenthe core of the planet and its surface, drives a continuous conductionof thermal energy in the form of heat from the core to the surface. From hot springs, geothermal energy has been used for bathingsince Paleolithic times and for space heating since ancient Romantimes, but it is now better known for electricity generation. Worldwide,about 10,715 megawatts (MW) of geothermal power is online in 24countries. An additional 28 gigawatts of direct geothermal heatingcapacity is installed for district heating, space heating, spas,industrial processes, desalination and agricultural applications.[1] 19. Tidal power, also called tidal energy, is a form of hydropower thatconverts the energy of tides into electricity or other useful forms ofpower. The first large-scale tidal power plant (the Rance Tidal PowerStation) started operation in 1966.Although not yet widely used, tidal power has potential for futureelectricity generation. Tides are more predictable than wind energyand solar power. Among sources of renewable energy, tidal powerhas traditionally suffered from relatively high cost and limitedavailability of sites with sufficiently high tidal ranges or flow velocities,thus constricting its total availability. However, many recenttechnological developments and improvements, both in design (e.g.dynamic tidal power, tidal lagoons) and turbine technology (e.g. newaxial turbines, crossflow turbines), indicate that the total availability oftidal power may be much higher than previously assumed, and thateconomic and environmental costs may be brought down tocompetitive levels 20. Hydropower, hydraulic power or water power is power that isderived from the force or energy of moving water, which maybe harnessed for useful purposes. Prior to the development ofelectric power, hydropower was used for irrigation, andoperation of various machines, such as watermills, textilemachines, sawmills, dock cranes, and domestic lifts.Another method used a trompe to produce compressed air fromfalling water, which could then be used to power othermachinery at a distance from the water.In hydrology, hydropower is manifested in the force of the wateron the riverbed and banks of a river. It is particularly powerfulwhen the river is in flood. The force of the water results in theremoval of sediment and other materials from the riverbed andbanks of the river, causing erosion and other alterations. 21. Wind power is the conversion of wind energy into a useful formof energy, such as using wind turbines to make electricity, windmills for mechanical power, wind pumps for pumping water ordrainage, or sails to propel ships.Large-scale wind farms are connected to the electric powertransmission network; smaller facilities are used to provideelectricity to isolated locations. Utility companies increasinglybuy back surplus electricity produced by small domesticturbines. Wind energy, as an alternative to fossil fuels, isplentiful, renewable, widely distributed, clean, and producesno greenhouse gas emissions during operation. However, theconstruction of wind farms is not universally welcomedbecause of their visual impact but any effects on theenvironment are generally among the least problematic of anypower source.
