An online presentation about Global Energy and Global Warming. Consist material of How much do we consume, Cubic Mile of Oil Equivalent, primary Sources of Energy in cmo, Historic Trend in Energy Use , Switching to Non-Fossil Energy, Hydroelectric, nuclear, Photovoltaic, wind, biomass, fossil energy.

Content Summary :
” * Worldwide consumption rate (per second)
o 37,000 gals of oil
o 150 tons coal
o 3.2 Mcf gas
* Units must have come from a veritable tower of Babel!
o Therms (or BTUs), Quads, MWh, Barrels (bbl), Tons, Tcf …
* Lack of uniform units presents a serious impediment to meaningful discussion
* Further confusion caused by the necessity to use millions, billions, trillions, and quadrillions of whatever
This is why we use fossil energy!
* Most projections show that the percentage of fossil fuel use will stay relatively constant
o We still have to build a lot of facilities!
o Rapid building in China
o Construction prices have risen 25-30%
* Increased renewables will keep pace with increased energy use and only increase slightly as a percentage of the overall energy use
What Should Be Done?
* Define goals
o Cost?
o Environment?
o National security?
o Reduce dependence on unstable/unfriendly countries?
* Continue expanding renewable energy using economic judgment
o How much extra are people willing to pay for fossil fuel alternatives?
* Make fossil fuel use as clean and efficient as possible
o Rise in natural gas costs — home heating costs rise
o Options for cleaner coal – IGCC, oxyfiring, CO2 sequestration
o Alternate liquid fuels – biodiesel, (ethanol), coal-to-liquids, biomass-to-liquids
* Nuclear
o Projected fuel shortage in ~30 years without breeder technology
o Wastes from breeder technology much smaller
+ handling large quantities of plutonium is a potential terrorist threat……..”
