2. Renewable Energy
 Energyexpertspredict thatbyendof currentcenturyi.e.after250 yearsof Industrial revolution
world’scoal and gas reserve whichtook200 millionyearstoformwouldhave beenburnt.
 Hence the needforalternate source of energyenergy.
 Needforrenewableenergyanditsuse isnotnew
o 1086-5600 watermillsoperatedinEnglandgenerating2kw of energy
o Adventof coal watermillsbecame indisuse
 Wind Turbines
o Commonsite inEurope
o Beinguglycauses“visual pollution”
 Locatedoutside insea
 No windnoelectricity
 Tidal flow scheme
o Example Gulf streamfromFloridatoScotland@1.5 m/s
o Currentturbinesakintowindturbinesoperate bestinshallow waterforfixinginbed
 Tidal Barrages
o Dams that getfilledwithseawaterwhentidescome
o Water releasedwhen tide goesoutgeneratingelectricity
o Disadvantage
 Limitedtidal barrage location
 Considerableimpactonlocal marine ecosystem
 Biofuels
o Wide range of materials
o Wood to Plantwaste
o Waste material fromanimals
o Fire wood
o Methane gas fromplantand animal waste
 Low production rate
o Biodiesel frommaize/wheatproduction
o Great potential butproblemof scalabilityasproductionisfarlowerthandesired
 Solarpower
o Withefficientsolarcells4% of worldenergyneedscanbe generatedfromdeserts of
the world
o Lessefficientphoto voltaiccells
o Highcapital cost -5-6 years forcost efficient
 Micro generation
o “thinkbig”to be replacedbysmall scale local generationusingbiofuels
o Potential tobe joinedtoformpowergrid
