Slide 5

Petroleum Fuel Future The fossil fuel supply is required to take after a ringer formed bend as created by M. Ruler Hubbert. The top in the bend of yearly supply is the critical point. US oil generation topped around 1970. World populace development is normal at 1% a year. US vitality utilization is expanding at 1.5% a year. The US imports 60% of its oil. Demonstrated world oil stores are around 2,000 billion barrels. Doubtful stores may help this to 3,000-4,000 billion barrels. For world oil request developing in the reach between 0-2 percent a year, the anticipated crest is appeared in the following slide. (A lifetime here is 75 years.) The mean appraisal of the stores of the Artic National Wildlife Refuge (ANWR) is 6 billion barrels (if the cost is more prominent than $25/barrel).

Oil Growth and Decline (1,000 Bbl holds)

Slide 9

US and World Natural Gas US request development is 3% every year. A deficiency now exists in the US and arrangements for Liquid Natural Gas (LNG) terminals for imports exist around the nation (Ventura, Long Beach, Baja California) The diagrams are for the time the supply will last. The units are in Quads (Quadrillion BTUs) The entire US vitality utilization in all structures is 100 Quads for each year.

Slide 11

Total stores, with characteristic gas saves in equal billion barrels of Oil (bbl). World oil utilization is 30 bbl/year. Forgotten Canadian tar sands at 179 bbl oil. US has 22 bbl oil, and creates 2.0 bbl/year and would last just 11 years. World Oil and Natural Gas Reserves

Slide 12

US Coal Supply The aggregate US coal store is 5700 Quads. The present rate of utilization is around 20 Quads for every year. Populace development will lessen its life span from 250 years at no development Conversion to engine fuel utilizes 2Quads of coal to create 1Quad of fuel in addition to the extra CO2 outflow. Transformation to hydrogen fuel utilizes significantly more. The chart expect 54% of underground coal is recoverable. Appraisals are for different development rates of utilization.

Dilute Fossil Residues Oil shale or tar sands has weaken measures of substantial oil or close strong carbonaceous deposits. Surface is mined at 2 tons for every barrel of oil. More profound stores are steam weakened and promote prepared to yield fuel, utilizing vitality, and costing CO2 creation. Expense is about $9/barrel before transportation. It likewise contains nitrogen and overwhelming metal mixes. The US has little. Overall evaluations are substantial however theoretical. 180 billion barrels worth in Canada. Hotspot for a few of the past charts is on the web in Physics Today, July 2004, by Paul B. Weisz.

Slide 16

Fossil Fuel Future Summary Oil, Natural Gas, Shale Oil, and Coal produce CO 2. Carbon sequestration requires an additional 30% of force and needs look into. FutureGen $1 billion exploration plant. Oil is required for transportation fuel Too costly for power era Reserves: About 50 years with development being used 2/3 is in the Middle East Coal might be changed over to fluid fuel for transportation 250 years at current rate, 100 years with transformation Total world store of oil is an extensive inquiry, utilizes politically inspired appraisals of individual nations Current rate of utilization of fossil fills will expand overall U S proposed atmosphere innovation program

Slide 17

Short Term Optimum The most ideal approach to hold down CO2 increments is to expel fossil energizes from power era, yet utilize it only for vehicles. Since ½ of US power originates from coal which creates twice as much CO2 per vitality unit as does regular gas, we ought to change to characteristic gas. This, notwithstanding, includes gigantic and potentially expensive imports. We require increments in interchange vitality sources, for example, hydro, atomic, wind and sunlight based. We likewise require increments in vitality proficiency and preservation. This particularly incorporates high mileage vehicles.

Comparative Projected Vehicle Fuel Economies

Slide 19

Cost of Gasoline and Taxes Elsewhere on the planet the expense of gas is around $1/liter, or $4/gallon. Gas charges per gallon in different nations: Great Britain $3.40 Italy $2.53 Germany $2.56 Japan $2.04 US Federal Excise Tax per gallon is $0.18 California Excise Tax is $0.18 Wisconsin is $0.31, Alaska is $0.08 California State and Local Taxes are $0.14 Total assessment in California is $0.50/gallon

II. Exchange Energy Sources Hydrogen Transmission Fusion Reactors Renewables: Hydroelectric Wind Power Solar Power Biomass, Ethanol Geothermal

Slide 23

The Hydrogen Dream Hydrogen is a transmitter of vitality, not a source: Must utilize fossil fuel (making CO 2 ) or high temperature reactors or sunlight based or electrical energy to make H 2 - needs explore Need power module innovation change (current $3000/kw versus $30/kw for a gas motor). Power devices join 2H 2 with O 2 to make 2H 2 O. However power modules are 60% productive contrasted with 22% for gas and 45% for a diesel motor. Impetuses in power devices are costly and can be harmed by polluting influences.

Slide 24

California Hydrogen Dreaming Need to set up a circulation framework on as extensive a scale concerning fuel California is building up a Hydrogen roadway of 200 stations for about $100 million Current expense of hydrogen is 4 times that of gas Compressed hydrogen tank has a scope of just 200 miles (50 for Arnold\'s Hummer demo) H 2 will presumably be put away in a littler volume atom like NaBH 4 Won\'t be down to earth for a long time Physics Today "The Hydrogen Economy"

Slide 25

Fusion Reactors Fusion most effortless for Deuteron (D) + Tritium(T): D(p,n) + T(p,nn) → 4 He(pp,nn) + n in a high temperature plasma. Substitution T made from Li cover around reactor n + 6 Li → 4 He + T Fusion reactors International ITER in 2012 for examination for 10 years, costing $5 billion Current stalemate over siting in France or Japan Followed by DEMO for a working plant, taking an additional 10 years. So not prepared for building units until no less than 2030. US Lithium supply would last a couple of hundred years. Still would be a radioactive waste transfer issue.
