1. OCS = outer continental shelf, map at:  US_OCS.png
2. These figures come from press releases of 3/31/10  and from information on this web site:
Fossil Fuel Reserves.htm US_Energy_Plan.htm
3. The US imports about 62% of the oil it burns.
4. Limited drilling is necessary to answer questions about reserves so we can get serious about going to
      future energy sources.
5. Even the Forbes estimates will not give us any longterm energy supplies.
6. Clean coal, nuclear fission, solar (incl. wind), and geothermal must still pick up the load within 50 yrs.

7. Perhaps geothermal power generation near volcanic hotspots could reduce super volcano eruptions.
       Possibilities include near Yellowstone and Hawaii, USA; near Naples, Italy; near Lake Toba, Sumatra.
       In the PBS NOVA program, "Mystery of the Megavolcano" the authors state that any future explosion
       of the Yellowstone hotspot would devastate much of the US. The NASA Planetary Sciences Unit
       has modeled such an eruption. The US might be able to generate a lot of geothermal power by 
       extracting heat near the hotspot. Could we extract heat fast enough to reduce, or prevent, a 
       catastrophic eruption and generate a lot of geothermal power at the same time?  Such a project 
       would give NASA a useful objective and might help solve our energy problem. Space.htm
8. Nuclear wastes are another source of heat and have been used to generate electrical power.
9. As the world converts from fossil fuels to electricity, quadrillions of Btu will be replaced by
     terawatt-hours. Since 1 kilowatt hour of electricity equals 3,412 Btu and 1 Quad Btu = 10^15 Btu, then:
1 Quadrillion Btu = 10^15 Btu/3412 = (1,000,000/3412)*10^9 kilowatt hours, or:
293 x10^9 kilowatt hours
1 Terawatt = 10^12 Watts = 10^9 kilowatts.
So, 1 Quad Btu = 293 TWhrs
      Since the US now uses about 100 Quad Btu per year, we use about 100*293, or 29,300 TWhrs per year.
