Solar Free and inexhaustible Fastest growing energy sources

20 Areas of Green Technology
Wind Cleanest Most sustainable Cost-competitive energy resources

21 Areas of Green Technology
Wind Pakistan Total Production: 15000MW US Wind Energy Production alone: 25000MW

22 Areas of Green Technology
Hydropower Flowing water creates energy Turned into electricity Largest source of renewable power worldwide

23 Areas of Green Technology
Hydropower Help decrease dependence on fossil fuels Reduce the threat of global warming.

24 Areas of Green Technology
Ocean Produce mechanical energy Currents represent a largely untapped source of energy

25 Areas of Green Technology
Ocean Powerful Highly-concentrated Clean energy resource

26 Areas of Green Technology
Biomass Produce electricity, transportation fuel and chemicals Constitutes trees, grass crops, forestry, agricultural, and urban wastes.

27 Areas of Green Technology
Biomass Biofuels 1.8% of the world's transport fuel Bioethanol Fuel for vehicles Used as gasoline additive

28 Areas of Green Technology
Biomass Biodiesel Waste vegetable oil to soybeans Diesel engines Landfill gas chemical reaction in landfill

29 Areas of Green Technology
Biomass Bullet 580 Runs on “algae” Bio-fuel that can be developed from brackish and waste water Maximum speed of 80 mph Capable of carrying loads of 2,000lbs up to 20,000ft

30 Areas of Green Technology
Geothermal Earth's internal heat Electric power production Large and complex power Simple pumping systems

31 Areas of Green Technology
Geothermal Geothermal energy Found almost anywhere Affordable Sustainable solution

32 Areas of Green Technology
Green Construction Green Building Current and future environmental impact Healthiest possible environment Most efficient and least disruptive use of land, water, energy and resources

33 Areas of Green Technology
Green Construction Energy efficient Use of Recycled content Environmentally sustainable materials Sustainable use of construction site Use of locally manufactured goods Indoor environmental air quality Vegetative Green Roofs

34 Areas of Green Technology
Green Construction Apparently expensive Economical in the longer run Increases the initial building costs, but Reduction in size and cost of the buildings’ heating and cooling system

35 Green Construction Example
Colorado Court, Santa Monica, USA

36 Ford Dearborn Truck Assembly Plant, Michigan, USA
Green Construction Example Ford Dearborn Truck Assembly Plant, Michigan, USA






42 Areas of Green Technology
Green Nanotechnology Manipulation of materials at the scale of the nanometer Transform the way everything is manufactured Application of green chemistry and green engineering principles

43 Goals of Green Technology
Sustainability "Cradle to Cradle" design Innovation Minimizing Pollution Source Reduction Viability

44 Goals of Green Technology
Sustainability Energy Conservation Solar, wind and hydroelectric power Utilization of energy efficient devices Energy Saver bulbs or CFLs

45 Goals of Green Technology
Cradle to Cradle Design Replacing the "cradle to grave" Achieved through Recycling Most common green technologies Help reduce waste/pollution.

46 Goals of Green Technology
Innovation Transportation Hybrid Cars Gasoline-electric Batteries helps reduce fuel emissions Minimize air pollution Living a cleaner, less expensive life

47 Goals of Green Technology
Minimizing Pollution Water and Waste Management Sewage Treatment Air Purification Solid waste management

48 Goals of Green Technology
Source Reduction Patterns of production and consumption Green Packaging Minimizing the amount of packaging Minimizing the energy used Using reusable packaging Using recycled and recyclable items Using biodegradable materials

49 Goals of Green Technology
Viability Center of economic activity Cost savings National security issue Efficient and cost effective business operations

50 Green Engine VITAL Aims to reduce Aircraft engine noise
Carbon dioxide emissions Major Partners SNECMA Airbus France Volvo Aero Rolls Royce

51 Green Engine Contra Rotating Turbofan (CRTF)
Two fans turning in opposite directions Reduce the fan rotating speed by 30% Same performance as a conventional fan Slower tip speeds, reduces fan noise Higher bypass ratio, results in lower fuel burn Reduced carbon dioxide emissions

52 Future 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.

53 Future Developments Bahrain World Trade Center
Three massive wind turbines Accelerates air moving between towers Generate even more power Largest wind-powered design in a massive building

54 Future Developments MagLev Wind Turbine
Using magnetism to levitate the blades Theoretically survive for centuries Power up to 750,000 homes 1 maglev wind turbine equals to standard wind mills

55 Future Developments Solar Tower Surrounded by 600 steel reflectors
Sunrays directed at a single point Turn water into steam. The steam moves through turbines and generates energy.

56 Future Developments Dongtan Eco-City
Environmentally, socially, economically and culturally sustainable city Relies on its own wind and solar energy as well as organic farming strategies Prototype for large-scale city planning Fully eco-friendly mindset.

57 Future Developments Lighthouse Skyscraper
1000-foot-tall office skyscraper Designed to use about half the water and energy of a typical high-rise building Solar energy collection and wind farming techniques Improve recovery of energy and water within the building.

58 Future Developments Orbiting Solar Arrays
Array of solar panels placed into orbit. Beam the solar power back down to a receptor Converted into electricity. No interruption of the flow due to adverse weather conditions or being night.

59 Future Developments Smart Grids
Overcome current electrical grid problems More efficient and cost-effective distribution and consumption of energy Integration of alternative energy sources Power flows optimized Carbon dioxide emissions reduced substantially

60 Problems with Going Green
Drawbacks Problems with Going Green Inconsistent Weather Not possible everywhere Cost of solar panels Short lifespan of energy infrastructure Hybrid car drawback


62 Conclusion Time to diversify our energy sources
Increased usage of solar, wind, water power Excess energy back to the national power grid Good business opportunity Promoting practices that will benefit our environment Solar energy has surpassed wind power generation Solar markets are growing at ten times the rate of the oil industry,

63 Conclusion Reduce energy consumption Enhance energy independence
Reduce operating costs Reduce electronic waste Improve public health Generate positive public relations Create new economic opportunities Strengthen our country START NOW


65 Global Warming The retreat of Aletsch Glacier in the Swiss Alps (situation in 1979, 1991 and 2002), due to global warming.
