  1. CLIMATE AND ENERGY

  2. Energy sources • 2.5 billion people have no access to modern energy services • Without it, they cannot: • Pump well water • Refrigerate food or medicine • Turn on an electric light to do homework

  3. How much energy do we use? • Big numbers. • The world: 320 billion kilowatt hours of energy everyday. • That’s equivalent to 22 bulbs burning non-stop for every person on the planet.

  4. Where is most of that energy being used?

  5. The Future? • One estimate: within the next century, Usage will 3X today • 66 bulbs burning for every person on the planet…NON STOP.

  6. Fossil fuels Coal oil natural gas They are not sustainable, nor are they renewable Energy Demands met by burning fossil fuels

  7. Results of global warming caused by burning fossil fuels: • Could lead to rising seas • Fiercer storms or changed weather patterns • Milder or more intense winters • Altered growing conditions which affect food supply • Severe droughts in some places • Severe flooding in others • Rise in skin cancer

  8. THEN WHY BURN FOSSIL FUELS? • Cheaper: It’s the system that we already have • Governments (especially the United States) provide incentives and subsidies for fossil fuel power output

  9. Government Subsidies • An amount of money that a government can pay a person, a company or an organization for many reasons: 1.) Assist them in a project, similar to a donation 2.) Encourage a behavior such as farmers not using all their land to grow a crop that already has low prices (Avoid swamping the market) 3.) Regulate the economy, stabilize or lower prices of something

  10. Alternative Sources • Wind • Solar Power

  11. Average house: 600-1000 kWh a month • Wind Source: 2007: $3.53/100 kWh block • Fuel Cost credit to compensate for fossil fuels not being used • Average cost: $0.86 per 100 kWh • You can sign up for 10%-100% of your energy use • 1.800.895.4999

  12. Alternative Sources • Geothermal • Biomass

  13. Alternative Sources • Hydropower • Nuclear Energy

  14. WHY NOT ALTERNATIVE SOURCES? • It is said that is it too expensive to change from the system we have at present • Subsidies for fossil fuels and some nuclear; alternative energy left out of the picture • Many companies are established that could do the change over, just waiting for the incentive….usually profits.

  15. WHAT CAN BE DONE? • Eliminate taxation and pricing systems that encourage oil use • Replace them with policies that encourage alternative energy use (SIMILAR SUBSIDIES that fossil fuels receive) • Governments are ALSO pressuring utilities to meet targets for renewable sources goals

  16. In Europe • Financial incentives for both wind and solar energy have broad support of the population even though they have raised electric bills

  17. INDIA • A boom in wind power was created because the government: • Made it easy to get the initial technology • Made it a requirement that the national power grid purchase its energy from that source • They are now the 5th largest generator of wind and solar power in the world • Granted $1.1 billion to alternative energy programs

  18. In Developing Countries: • In the developing world, affordable energy is a necessity, not a choice. • Solar power is increasing in African communities lacking power lines and generators • Both solar and wind energy can be used by a single household, privately. • You can have solar panels on your house or a wind turbine or windmill for your own use…..You can’t have your own private power plant • Solar power can provide energy to places that otherwise would not have it

  19. Alternative Energy Investigation • Using the template provided, investigate the following alternative energy sources with a partner: • Hydropower • Solar power • Wind power • Geothermal power • Biomass power • Nuclear power
