    • The Renewable Energy Industry
    • What is Renewable Energy?
      "Renewable energy: Any energy resource that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun, or from other natural movements and mechanisms of the environment.”
      Non-renewable energy resource: an energy resource that is not replaced or is replaced only very slowly by natural processes.
    • Renewable energy usage in the last decade
      Since the year 2000 the amount of renewable energy used has gone up drastically. From a nearly immeasurable amount in 2000 to almost 10 million in 2008.
    • The Four Most Common Types
      • Wind Energy
      • Uses wind turbines to create electricity
      • Geothermal Energy
      • Uses heat from the earth’s core to create energy
      • Solar Energy
      • Uses rays from the sun to create energy
      • Hydropower Energy
      • Uses water to create energy
    • Wind Energy
      Converts wind to energy by using turbines and mills
      The modern wind power industry began in 1979
      In 2009 159.2 gigawatts were produced world wide
      Has been used for 5,500 years
      Has a potential to generate 72 terawatts per year
    • Wind Energy in the U.S.
      The United States is the world leader in wind energy production
      Produced 35,159 megawatts in 2009
      Texas produces more than any state with 9,728 megawatts captured in 2009
      Employs 85,000 people in the U.S.
      Illinois produced 1,547 megawatts in 2009
    • Wind Energy Abroad
      Germany trails the U.S. by about 30% in total production
      Together the European Union produces over twice as much as the U.S.
      Map
    • Interesting Fact
      The world’s largest wind turbine is the E-126 first built in Emden, Germany
      E-126 can also be found in Belgium and Sweden
      It is 650 ft tall with a rotor diameter of 413 ft
      Built in 2007
    • Geothermal Energy
      • Heat from the earths core is used to boil water which turns a turbine attached to a generator
      • Three ways to capture
      • Dry Steam
      • Flash Steam
      • Binary Cycle
      • Reservoirs are classified as being either low temperature (below 150°C) or high temperature (above150°C)
    • Geothermal in the U.S.
      The United States is the leader in geothermal energy usage
      There are approximately 77 plants across the U.S.
      Our country has the capacity to produce 3086 MW of energy today
      The heaviest concentration of geothermal plants is located in California
      Previously geothermal energy was only accessible near tectonic plate edges
    • Geothermal Across the Globe
      Over 24 countries use geothermal energy
      The Philippines is the number two producer
      Geothermal is Iceland’s main energy source
      Worldwide 10,715 MW of power are produced
    • Pro vs. Cons
      PROS
      Once installed it is very cheap to operate
      Not dependent on gas or electricity to provide heat
      Low emissions
      Green energy
      CONS
      Amount of land required
      Start up costs are expensive
      Lack of accessible sites
    • Interesting Facts
      • For every 328ft below the ground drilled, the temperature rises 5.4 degrees Fahrenheit
      It is considered a renewable resource
      Geothermal got its name from the Greek words geo (earth) and therme (heat)
      Hot springs and geysers are natural examples of geothermal activity
    • Companies & Users
      The Geothermal Energy Association provides its members breaking news on the subject
      Mitsubishi: +80 different locations worldwide
      Sky Power Systems, GeothermEX Inc, and Mitsubishi Power Systems Inc. are the major plants in California
    • Solar Power
      Solar power is created by collecting sunlight and converting it into electricity
      This process is called photovoltaic or pv for short
      This is done by using solar panels, which are solar cells made from silicone that absorb the sun’s radiation
      Solar cells produce direct current electricity
      Can be used to power equipment or to recharge a battery
    • Pros and Cons of Solar Energy
      Pros
      No Pollution
      It does not burn fuel and generates no emissions
      Saves you Money
      You’ll be using less energy, so utility bills will be much lower and often nothing at all.
      TaxBreaks
      The U.S. government offers a tax credit
      Nearly Maintenance Free
      Manufacturers are offering warranties of 20 years
      Energy Credits
      You can build a credit of energy if your solar system produces more energy than you use
      The Noise Factor
      They are silent and have no moving parts.
      Cons
      • Expensive
      —The main disadvantage is the price. The panels and installation have high starting costs
      • Not 24 Hours
      — They only work when the sun is shining
      • Aesthetics
      — Solar panels take up quite a bit of roof space and to some and aren’t pleasant to look at
    • America’s Potential for Solar Power
      You ask why not use solar energy since there are more pros than cons?
      Top states of potential solar energy
      New Mexico
      Arizona
      Nevada
      Utah
      California
      Solar Calculator
      American Solar Power
    • Water Power: as renewable energy
      +(Hydropower refers to process in which water is used as means to generate electricity.)+
      Became widespread: 18th Century
      First to use: Greeks
    • United States: Hydropower Usage
      81 % of our nations renewable electricity generation deriving from HydropowerIn the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power. (1940) Now 6-8%
      The old “Schoelkopf Power Station No. 1” near Niagara Fallsin the U.S. side began to produce electricity in 1881.
      By 1889 there were 200 Hydroelectricity plants within the U.S. Very few companies that make hydroelectric turbines, can be purchased/used to power homes, small businesses, and small scale farms.
    • Where the rest of the fits:
      Hydropower is to thank for 19% of total electricity production worldwide.
      China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States –Energy Information Administration.
      Approximately 2/3 of the economic possible potential remains to be developed. Untapped hydro resources are still abundant in Latin America, Central Africa, India and China.
      In 1878, the world's first house to be powered with hydroelectricity was Cragside in Northumberland, Enlgand.
      New Zealand’s electricity is 80% renewable (mostly hydropower).
      In South America, overall about 40% of electrical generating capacity is hydroelectric.
      Brazil yielded a percentage of 86% in 1998.
      Over 50% yeilds of potential generating capacity for the following countries: Chile, Colombia, Paraguay, Peru, and Venezuela.
      In Chile, a $0.5 billion renewable energy project recently suspended due to controversy over relocating indigenous peoples.
      China’s Yangzte River projects are the world’s most ambitious due to motivation of two month death tolls of 3,000 dead, 5,000,000 homeless in a 1998 flood.
      Countries worldwide are doing extensive research as well as developing budget’s for such facilities.
    • Pro’s+V.S-Con’s:
      -37.8 million homes powered.
      -Renewable-saving fossil fuels.
      • Recreation opportunities on upstream reservoirs.
      • Habitat for a wide variety of aquatic and terrestrial species
      • Diversion of water(irrigation), and control of destructive flooding and environmental damage downstream.
      -Reducing your exposure to future fuel shortages/price increase.
      -Hydropower plays a major role in reducing greenhouse gas emissions.
      - Potential destruction of land and wildlife habitat
      -High investment costs
      -Water Dependent
      • Fish entrainment or passage restriction (potential loss/modification of natural habitat).
      -Can result in displacement of local populations
    • In Conclusion
      In conclusion renewable energy is a growing industry that not only benefits the businesses involved but also is good for reducing global warming and our dependence on fossil fuels.
      There are many types of renewable energy all of which have their own positives and drawbacks
