Doe dollar per watt overview

  1. 1. Is it Time for a “Sun Shot”? $1/Watt Workshop Washington, D.C. 10 August 2010
  2. 2. “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard. “Because that goal will serve to organize and measure the best of our energies and skills. “Because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win….”John F. Kennedy - September 12, 1962

  4. 4. Days above 100º F <10 20 30 45 60 75 90 105 >120 Much of the U.S. would go from 0 - 10 days above 100º F to 45 to 70 days per year above 100º F 4Source: NOAA U.S. Global Change Research Program
  5. 5. Global Sea Level: 2007 IPCC Technical Summary Past 2000 years: 0.0 - .02 mm/year 1870 – 1890: 0.6 mm/year 1990 – 2008: 3.0mm/year (including recent satellite data) 5
  6. 6. The sea level is rising. Past 2000 years: 0.0 - .02 mm/year Currently 3.0mm/year Greenland Ice Mass Loss – 2002 to 2009 Ice mass loss from the Greenland and Antarctic ice sheets measured by GRACE (Gravity Recovery and Climate Experiment) mission.

  7. 7. Carbon Dioxide Concentration during the past 800,000 yearsSince the beginning of the industrialrevolution, the CO2 in the atmosphere has increased by 40%. The CO2 equivalenthas increased by 53% 2008 7
  8. 8. 14C is produced through cosmic-ray bombardment. It is incorporated into plants and animals and decays with a 5,730 year half-life.Fossilized organic material is depleted of 14C. Burning fossil fuel will add 12C to the atmosphere and lower the 14C/ 12C ratio.
  9. 9. The decline in 14C is toorapid to be explained by mixing and radioactive decay alone.
  10. 10. 1) Solar energy hitting the Earth from the sun, averaging over the 11 year solar cycles, is constant. (Input energy remains constant)2) Atmospheric greenhouse gases have increased. (Less energy out)3) As the Earth begins to heat up, it is known that the change in temperature will be less than predicted by simple Energy in – Energy out analysis. The details of the geochemical and biological responses are not fully known. 3) The Earth will warm up until a new equilibrium is reached: When heat radiation out equals the absorbed solar energy. (100 -200 years)
  11. 11. Solar PV is a booming global industry But U.S. market share has fallen to about 5% of global output – from more than 40% in the mid-1990s U.S.Worldwide production of solar photovoltaics – in Megawatts 11

  23. 23.

  24. 24. We need a new mindset on cost-reduction.Things we’ve never paid attention to before will be the difference between success and failure. What can we learn from other industries? 24
  25. 25. Agriculture From this… …to this. • Laser-leveled fields • Fertilizer measured by satellite • Harvested with GPS-enabled precision combines
  26. 26. Upgrading 6,500 dual pane windows in the Empire State BuildingInnovative on-site processing – glass is removed, cleaned, retrofitted, andreinstalled without leaving the building
  27. 27. Containerized shipping hastransformed global commerce In 1959, the shipping industry loaded and unloaded 0.627 tons per man hour. By 1976, the figure was 4,234 tons per man hour. A ships time in port shrank from three weeks to 18 hours. Source: Matson Navigation Co.
  28. 28. • Minimize material use•Lower weight, non roof-penetrating• Micro-electronics integration• Automated installation
  29. 29. Solar Shingles – or DIY solar – could nearly eliminateincremental PV installation costs
  30. 30. Earthrise from Apollo 8 (December 24, 1968)"We came all this way to explore the moonand the most important thing is that wediscovered the Earth.“ Bill Anders, Apollo 8 Astronaut 30
  31. 31. In 1990, Carl Sagan convincedNASA engineers to turn Voyager for one last, homeward look before “Look again at that dot. Thats here. Thats leaving the solar system home. Thats us. On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives …. Every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, … every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.” “….The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate … Like it or not, for the moment the Earth is where we make our stand.” 31
  32. 32. Deeply rooted in all cultures, is thenotion of generational responsibility. Parents want to give their children better economic opportunities… and leave the world a better place. 32
  33. 33. • Science is predicting that we are alteringthe destiny of the of the Earth.• The full impact of what we have donealready will not be known for 100+ years.The full cost of future damages is not known.• Are we willing to make investments thatwill protect our children and grandchildren? 33
  34. 34. An ancient Native American saying:“Treat the earth well: it was not given toyou by your parents, it was loaned to youby your children.”Our generation is in danger of breaking this sacred trust. 34
