36Ford Dearborn Truck Assembly Plant, Michigan, USA Green Construction ExampleFord Dearborn Truck Assembly Plant, Michigan, USA
42Areas of Green Technology Green NanotechnologyManipulation of materials at the scale of the nanometerTransform the way everything is manufacturedApplication of green chemistry and green engineering principles
43Goals of Green Technology Sustainability"Cradle to Cradle" designInnovationMinimizing PollutionSource ReductionViability
44Goals of Green Technology SustainabilityEnergy ConservationSolar, wind and hydroelectric powerUtilization of energy efficient devicesEnergy Saver bulbs or CFLs
45Goals of Green Technology Cradle to Cradle DesignReplacing the "cradle to grave"Achieved through RecyclingMost common green technologiesHelp reduce waste/pollution.
46Goals of Green Technology InnovationTransportationHybrid CarsGasoline-electricBatteries helps reduce fuel emissionsMinimize air pollutionLiving a cleaner, less expensive life
47Goals of Green Technology Minimizing PollutionWater and Waste ManagementSewage TreatmentAir PurificationSolid waste management
48Goals of Green Technology Source ReductionPatterns of production and consumptionGreen PackagingMinimizing the amount of packagingMinimizing the energy usedUsing reusable packagingUsing recycled and recyclable itemsUsing biodegradable materials
49Goals of Green Technology ViabilityCenter of economic activityCost savingsNational security issueEfficient and cost effective business operations
51Green Engine Contra Rotating Turbofan (CRTF) Two fans turning in opposite directionsReduce the fan rotating speed by 30%Same performance as a conventional fanSlower tip speeds, reduces fan noiseHigher bypass ratio, results inlower fuel burnReduced carbon dioxide emissions
52Future Developments Lilypad Project Futuristic concept Series of floating self-sufficient ocean-going eco-city islands.Support great deal of biodiversity.Collecting pools located in their centers would gather and filter water for use on board.For adventurers and refugees alike as water levels rise around the world.
53Future Developments Bahrain World Trade Center Three massive wind turbinesAccelerates air moving between towersGenerate even more powerLargest wind-powered design in a massive building
54Future Developments MagLev Wind Turbine Using magnetism to levitate the bladesTheoretically survive for centuriesPower up to 750,000 homes1 maglev wind turbine equals to standard wind mills
55Future Developments Solar Tower Surrounded by 600 steel reflectors Sunrays directed at a single pointTurn water into steam.The steam moves through turbines and generates energy.
56Future Developments Dongtan Eco-City Environmentally, socially, economically and culturally sustainable cityRelies on its own wind and solar energy as well as organic farming strategiesPrototype for large-scale city planningFully eco-friendly mindset.
57Future Developments Lighthouse Skyscraper 1000-foot-tall office skyscraperDesigned to use about half the water and energy of a typical high-rise buildingSolar energy collection and wind farming techniquesImprove recovery of energy and water within the building.
58Future Developments Orbiting Solar Arrays Array of solar panels placed into orbit.Beam the solar power back down to a receptorConverted into electricity.No interruption of the flow due to adverse weather conditions or being night.
59Future Developments Smart Grids Overcome current electrical grid problemsMore efficient and cost-effective distribution and consumption of energyIntegration of alternative energy sourcesPower flows optimizedCarbon dioxide emissions reduced substantially
60Problems with Going Green DrawbacksProblems with Going GreenInconsistent WeatherNot possible everywhereCost of solar panelsShort lifespan of energy infrastructureHybrid car drawback
62Conclusion Time to diversify our energy sources Increased usage of solar, wind, water powerExcess energy back to the national power gridGood business opportunityPromoting practices that will benefit our environmentSolar energy has surpassed wind power generationSolar markets are growing at ten times the rate of the oil industry,
63Conclusion Reduce energy consumption Enhance energy independence Reduce operating costsReduce electronic wasteImprove public healthGenerate positive public relationsCreate new economic opportunitiesStrengthen our countrySTART NOW
