1. Energy Literacy What does it mean to be a literate person? What comes to mind when I say “energy literate person”? If someone is an “ energy literate citizen” What knowledge does this person possess? What issues is this person familiar with? What energy choices does this person make?

2. Energy Literacy Do we have an energy literate society? What is the cost of energy illiteracy? What is the relationship between energy literacy and energy practices (our personal choices and actions?

3. Energy Literacy “ Americans are, in general, the least energy-conscious people on the planet. We are not only profoundly ignorant about what energy is, and the critical role it has played and continues to play in economics and politics, but most of us simply don’t care about energy. Paul Roberts, The End of Oil

18. Refining Oil Petroleum (crude oil) is a liquid composed of hundreds of hydrocarbon compounds; during petroleum refining, the compounds are separated into different products such as gases, gasoline, heating oil, diesel oil, and asphalt Oil can also be used to produce petrochemicals used in the production of fertilizers, plastics, paints, pesticides, medicines, and synthetic fibers

19. Oil 65% of the world’s known oil reserves are located in the Persian Gulf (CLICK, CLICK) Oil production is expected to peak sometime during the 21st century and will then enter a decline Organization of Petroleum Exporting Countries includes: Algeria, Angola, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, Venezuela Hubbert curve

21. Hubbert curve- a graph that shows the point at which world oil production would reach a maximum and the point at which we would run out of oil. The Hubbert Peak

22. Natural gas is separated into: Liquefied petroleum gas – propane and butane; used as fuel for heating and cooking Methane – used for heating, generating electricity, and in the organic chemistry industry Availability – supplies ~ 62% of energy used worldwide

23. Natural Gas Almost half of the world’s known natural gas reserves are located in Russia and Iran Reserves are more plentiful than oil and could continue to rise Because it is a gas, it costs 4x more to transport through pipelines and is therefore often not

26. Solutions Natural gas is cleaner burning and more plentiful than oil Cogeneration – natural gas is used to produce both electricity and steam, providing electricity cleanly and efficiently

27. Cogeneration- using a fuel to generate electricity and to produce heat. Example- If steam is used for industrial purposes or to heat buildings it is diverted to turn a turbine first. This improves the efficiency to as high as 90%. Cogeneration

28. Synfuels – derivatives of fossil fuels Tar sands / Oil sands - underground sand deposits permeated with a thick, asphalt-like oil called bitumen; once obtained, bitumen must be refined like crude oil Oil shales – rocks containing a mixture of hydrocarbons known as kerogen; rocks must be crushed and heated, then keragen must be refined

29. Synfuels Gas hydrates – reserves of ice-encrusted natural gas located deep underground in porous rock Coal liquefaction – process of producing a liquid fuel out of coal, that can be cleaned before burning Coal gasification – production of methane gas from coal

31. An Energy Strategy for the United States Reasons for a comprehensive energy policy The supply of fossil fuels is limited The production, transport, and use of fossil fuels pollutes the environment Our heavy dependence on foreign oil makes us economically vulnerable

32. An Energy Strategy for the United States Secure fossil fuel energy supplies – domestically produced fossil fuels (especially natural gas) are a temporary strategy that will give us time to develop alternate energy strategies for the long term Develop alternative energy sources –a long-term goal to shift to renewable forms of energy Accomplish the first three objectives without further damaging the environment – use cost/benefit analysis when considering particular energy sources

33. Proposed objectives Increase energy efficiency and conservation Reduce government subsidies (support in the form of monetary payments, public financing, tax benefits, and tax exemptions) keep energy prices artificially low; when prices reflect the true costs of energy, including the environmental costs incurred in its production, transport, and use, energy will be used more efficiently by individuals, corporations, and industries
