Fournier and E. Westervelt, September 2005, U.S. Army Corps of Engineers Research and Development Center http://www.defenseindustrydaily.com/files/2005-09_US_Army_Corps_of_Engineers_Energy_Trends.pdf Slide7: “Once worldwide petroleum production peaks, geopolitics and market economics will result in even more significant price increases and security risks. “Oil wars are certainly not out of the question.” - ibid Slide8: “The problem is refineries are not prepared to take the oil that is available today. They need to make investments to handle sour oil.” - Edmund Daukoru, President of OPEC and Minister for Petroleum Resources in Nigeria, http://www.peakoil.net/OilSummit2006.htmlSlide9: “Peak oil is not a theory; 33 out of 48 of the largest oil producing countries have hit peak. It will require more than a decade to transition our civilization away from our heavy dependence on oil. Nothing close to the efforts envisaged have yet begun. - Testimony by Robert Hirsch, SAIC, at the Pentagon and U.S. Congressional Committee on Energy and Commerce hearing, from the "Hirsch Report", commissioned by the Department of Energy -http://energycommerce.house.gov/108/hearings/12072005Hearing1733/hearing.htm and "Peaking of World Oil Production: Impacts, Mitigation and Risk Management www.netl.doe.gov/otiic/World_Oil_Issues/Oil_Peaking_NETL.pdfSlide10: Some say we are at peak oil now. Some say it is years away. Regardless of which is true, we need to quickly prepare for “demand destruction” - when rising oil prices and declining supply will slowly reduce oil demand – consumers - from the market.* These are typically transportation of people to work and goods to market. Electrification of transportation is necessary - which Japan has done more fully than any other industrial nation. *Update: on October 11, 2006, for the first time in two decades, oil demand in developed countries contracted, [IEA]. “Oil demand shrinks in developing countries”, www.ft.com/cms/s/71ed02d6-594b-11db-9eb1-0000779e2340.html ]Slide11: Mexico’s Super giant field Cantarell is in Decline Pemex CEO says production will fall without massive help to develop Ku-Maloob-Zaap, a heavy crude and/or Chicontepec with small oil pockets within fractured rock. Developing Chicontepec requires $38 billion to drill 20,000 wells, more than Pemex has drilled in 70 years. (With drilling technology Pemex doesn’t have.) Mexico’s Congress refuses to allow private investment. - “Pemex Oil Output to Drop Without Private Investment” March 30 (Bloomberg) http://www.bloomberg.com/apps/news?pid=10000086&sid=aiCFqPwH6eo4 Slide12: China passed Japan as the #2 world oil importer in 2004. Global oil demand is surging. China burns more coal than the US. Slide13: Welcome to the new Cold War A bitter pricing dispute with Ukraine disrupted Russia's natural-gas supplies to Europe, fueling fears over Moscow's growing clout as an energy supplier to Europe. Doubts about Russia's reliability and intentions as an energy supplier dominated the European press. "Welcome to the new Cold War," wrote the London Times, describing Moscow's leading role as energy supplier "Russia's most powerful weapon in its post-Soviet arsenal.1" [1] “Gas price dispute worries Europeans” by Andrew Borowiec and David Sands, January 4, 2006 The Washington Times www.washtimes.com/world/20060103-103729-1692r.htmSlide14: Some Peak Oil links : Association for the Study of Peak Oil (ASPO) http://www.peakoil.net/ Energy Bulletin (ODAC) http://www.energybulletin.net/ Oil Depletion Analysis Centre (ODAC) http://www.odac-info.org/ Matthew Simmons http://www.simmonsco- intl.com/research.aspx?Type=msspeeches Increasing levels of CO2 are : Increasing levels of CO2 are impacting all ecosystems. Slide16: Ocean pH has become 30% more acidic. This affects calcification by organisms including phytoplankton and zooplankton, a major food source for fish and other animals. - "Ocean acidification due to increasing atmospheric carbon dioxide", page vi, Royal Society Policy: www.royalsoc.ac.ukAt our current rate of increase CO2 levels will be doubled by mid-century. How are, and will, such changes impact us? : At our current rate of increase CO2 levels will be doubled by mid-century. How are, and will, such changes impact us?

Resulting in reduced nutrition from forage and grasses grown under doubled CO2 .Slide20: Ruminants, including cattle, sheep, oxen, buffalo, deer, etc., are the source of nearly all the milk and half the meat the world eats. They will gain weight more slowly under under doubled CO2 »» Kansas State University http://spuds.agron.ksu.edu/gainco2.gifNutrition from grains drops - wheat: Rice and wheat, the top grains in the world, both decline in nutritional value based on testing under elevated CO2. Wheat grown at doubled CO2 declines in protein content by 9-13%. Wheat grown at high CO2 produces poorer dough of lower extensibility and decreased loaf volume. Hence, for bread making, the quality of flour, produced from wheat grain developed at high temperatures and in elevated CO2, degrades. Nutrition from grains drops - wheatNutrition from grains drops - rice: “The nutritive value of rice was also changed at high CO2 due to a reduction in grain nitrogen and, therefore, protein concentration.” The protein content of rice declines under combined increases of temperature and CO2. Iron and zinc concentrations in rice, important for human nutrition, would be lower. Nutrition from grains drops - riceSlide23: Wild Bees And The Flowers They Pollinate Are Disappearing Together An international team of researchers from the UK, the Netherlands and Germany compiled biodiversity records for 100s of sites, and found that bee diversity fell in almost 80% of them. Over the last 25 years, many bee species are declining or have become extinct. Plant declines closely mirrored those of their pollinators. Researchers were shocked by decline in plants as well as bees. If this pattern is replicated elsewhere, the 'pollinator services' we take for granted could be at risk.“, said Dr Koos Biesmeijer, Univ of Leeds. The economic value of crop pollination worldwide is between £20 and 50 billion each year.

Where does “regular weather” end and climate changed weather begin? “Abrupt climate change” is a growing and poorly understood concern. Slide25: Global Ocean Slowing – Temporary or Increasing? Much of the ocean water in the high latitudes of the North and South Atlantic has grown fresher over the last fifty years, as tropical Atlantic waters became dramatically saltier. These were due to evaporation rates over the tropical Atlantic increasing by 5% - 10 over the last 40 yrs. “The ocean current that gives western Europe its relatively balmy climate is stuttering, raising fears that it might fail entirely and plunge the continent into a mini ice age. A study of ocean circulation in the North Atlantic found a 30% reduction in the warm currents that carry water north from the Gulf Stream.” - "Failing ocean current raises fears of mini ice age" by Fred Pearce, Nature (vol 438, p 655) www.newscientist.com/article.ns?id=dn8398 See also www.whoi.edu/institutes/occi/viewArticle.do?id=9206 www.mbl.edu/inside/what/news/press_releases/2006_pr_08_24.html Slide26: Source: (Broecker, 1995) “Abrupt Climate Change: Inevitable Surprises”, National Research Council. - makes London warmer than NYSlide27: More Bigger Hurricanes The number of Category 4 and 5 hurricanes worldwide has doubled over the past 36 years, even though the total number of hurricanes has dropped since the 1990s. The only region in the world experiencing more hurricanes and tropical cyclones overall is the North Atlantic, where they have become more numerous and longer-lasting, especially since 1995. The shift occurred as global sea surface temperatures have increased over the same period. – “Changes in Tropical Cyclone Number, Duration, and Intensity in a Warming Environment”, by P. J. Webster, G. J. Holland, J. A. Curry, H.-R. Chang, Science, 16 September 2005: Vol. 309. no. 5742, pp. 1844 – 1846 http://www.sciencemag.org/cgi/content/full/309/5742/1844 and www.ucar.edu/news/releases/2005/hurricanestudy.shtml See also http://www.gatech.edu/news-room/release.php?id=898 Slide31: Global Dimming Increased evaporation rates also increase cloud cover. Scientists have measured the loss of sunlight at about 2-3% per decade during much of the last half of the twentieth century. Concentrated at northern and mid latitudes, published estimates of the global average value are: 5.3% (9 W/m²) over 1958-85 (Stanhill and Moreshet, 1992) 2%/decade over 1964–93 (Gilgen et al, 1998) 2.7%/decade (total 20 W/m²) up to 2000 (Stanhill and Cohen, 2001) 4% over 1961-1990 (Liepert 2002)[i] [i] “Global Dimming II” 19 Jan 2005, Guest commentary on BBC documentary on "Global Dimming" aired on January 13th 2005 by Beate Liepert, LDEO, Columbia University http://www.realclimate.org/index.php?p=110 last accessed 3/22/06Slide32: “Human activities are increasingly altering the Earth's climate. Scientific evidence strongly indicates that natural influences cannot explain the rapid increase in global near-surface temperatures observed during the second half of the 20th century. Research indicates that increased levels of carbon dioxide will remain in the atmosphere for hundreds to thousands of years. ... “Scientific research provides a basis for mitigating the harmful effects of global climate change through decreased human influences, technological advancement, ... - adopted by the Council, American Geophysical Union, December, 2003Slide33: “The costs of natural disasters, aggravated by global warming, threaten to spiral out of control, forcing the human race into a catastrophe of its own making”. The economic costs of such disasters threaten to double to $150 billion a year in 10 years, hitting insurers with $30-40 billion in claims, or the equivalent of one World Trade Centre attack annually. "There is a danger that human intervention will accelerate and intensify natural climate changes to such a point that it will become impossible to adapt our socio-economic systems in time. The human race can lead itself into this climatic catastrophe -- or it can avert it.” - World's second-largest reinsurer, Swiss Re, Geneva (Reuters) March 3, 2004 Slide34: “2005 was marked by record losses from hurricanes in the North Atlantic, with insured losses exceeding US$ 83 billion and about $350 billion dollars of uninsured economic loss, e.g., including lost profits, lost business opportunities, etc. Florida’s largest property insurer, State Farm Insurance, raised their average hurricane rates from $1,733 to $3,101 this year. - “Hurricanes – More intense, more frequent, more expensive Insurance in a time of changing risks” Munich Re and American Re, (The 2005 hurricane season) April 2006, page 18, http://www.munichre.com/publications/302-04891_en.pdf?rdm=1825 Slide35: In Summary Oil production slowly declines as oil prices set record highs against roaring demand, triggering other price increases. Declining oil stocks intensify global tensions. Production of nutritious food is very slowly declining, similar to Biosphere II. Many agricultural regions experiencing increasing drought. Water for irrigation is in short supply. Fertilizer, essential to maintaining nutritious crops becomes more expensive as natural gas and electricity rise in cost. Global Ocean Circulation has begun slowing, warping our climate further. Energy alternatives reveal SSP to be key energy solution Slide36: Gasoline, diesel and jet fuel for transportation are the largest oil users. Global oil usage is inefficient, producing more waste heat and injecting more CO2 into the atmosphere per unit of work than any other fossil fuel. Conservation & more efficient technology could help:Slide37: Instant on water heaters, high efficiency refrigerators,.. Cutting oil usage with carpooling, hybrid cars, light rail and bicycles would help. Switzerland survived a six-year complete oil embargo during World War II with electrified transportation. Transportation is the largest and least efficient primary energy user. http://www.energybulletin.net/14492.html. So conservation and more efficient technology is important, but not enough.Slide38: Generous Federal and state subsidies and incentives for many types of renewable energy. These are summarized by state at the Database of State Incentives for Renewable Energy: http://www.dsireusa.org/ These efforts are ineffectual - they won’t get the job done. The EIA forecasts no impact – no decline - in CO2 emissions as a result of current policies through 2025. Slide39: Nuclear Proliferation … and war? Iran said it could defeat any American military action over its controversial nuclear drive. The United States accuses Iran of using an atomic energy drive as a mask for weapons development. US news reports said President George W. Bush's administration was refining plans for preventive strikes on Iran's nuclear facilities. Iran announced it had successfully enriched uranium to make nuclear fuel, despite a UN Security Council demand for the work to be halted by April 28. - “Iran issues stark military warning to United States”, April 15, 2006 Copyright AFP 2005, AFP Slide40: With SSP -- that nuclear power plant 93 million miles away nuclear waste problems nuclear fuel supply worries nuclear proliferation problems Evaporate .. Slide41: SPS requires no fuel and has no operations personnel – it is an antenna – with farms underneath. It is the cleanest source of virtually unlimited baseload energy. SSP is available 99% of the year at GSO. Baseload nuclear or coal plants are available only 90%. Slide44: Source: Matula, Thomas L and Karen A. Loveland.

The technology to build an SSPS system is available now. Slide46: No company(s) or agency(s), however, is prepared to assume the immense financial risk of initiating construction of an SSPS. There are simply too many engineering, financial, regulatory and managerial risks for any group we have been able to identify to undertake SSP today. But this road has been traveled many times before ... Slide47: As we detailed last year, there is a tried and true vehicle, that could initiate SSP construction today. A private Congressionally chartered corporation has all the requisite advantages. Comsat Corp., chartered in 1962, opened space for communication satellites - in a time when we knew almost nothing about space, rockets or the space communications business. The Sunsat Act would accomplish the same task for power satellites. Slide48: Thank you for the privilege of speaking to you today about the need for Space Solar Power. The tremendous promise of Space Solar Power for the entire world makes your work important.
