National effort/priorities to include schools/education

ACORE teams up with Partners GREEN and their “Project EverGreen Schools” Initiative in an effort to transition America’s schools towards Energy Efficiency and Renewable Energy

The American Council on Renewable Energy (ACORE) announced today that it has joined forces with Partners GREEN in signing a letter to President Obama voicing its strong support for the Partners GREEN’s project, “Onsite Renewable Energy, Efficiencies and Education at Our Nation’s Schools.” ACORE and Partners GREEN will ask ACORE Members to join in signing this “Letter to President Obama” before the letter is delivered to the President on February 26, 2009, through the RETECH Conference in Las Vegas, NV.

President Obama has called for renewable energy efficiencies, and educational programs to be brought to our nation’s schools and, in response to that challenge, Partners GREEN launched a petition drive to secure support for a national energy policy consistent with President Obama's goal for “greening” the nation's schools.

"I'd put my money on the sun and solar energy.What a source of power! I hope we don't have towait till oil and coal run out before we tackle that."Thomas Edison (1847-1931)

converting the sun s radiation into electricity two main pathways
Converting the sun’s radiation into electricity – two main pathways

Concentrating Solar Power (CSP)

Mirrors focus solar radiation to heat fluids that are used to drive electric generators.

Photovoltaics (PV)

Cells of semi-conductors absorb photons and directly convert them into electrical current.

Predominantly in the Southwest U.S. (requires direct sunlight)

Can be used anywhere in the U.S.

the challenges requirements
The Challenges/Requirements
  • Systems that deliver reliable (20 to 30 yrs.) retail-competitive electricity for a wide variety of markets & applications.
  • Systems that have optimized capacity (storage) factors that make them attractive to electrical grid and certain markets.
  • Large-scale (gigawatts) U.S. industrial manufacturing & deployment capacities that will dramatically reduce component, system, and installation costs.
  • A national workforce commensurate with large scale development and deployment. Education and training at all levels.
  • Acceptable/value-added grid integration; Smart Grids.
  • Advanced solar resource prospecting and forecasting (1 hour to 1 week) technologies and tools.
  • Financing mechanisms to facilitate affordability.

u s solar resources significantly outweigh energy use
U.S. solar resources significantly outweigh energy use
  • Currently, solar provides less than 0.1% of the electricity used in the U.S.
  • For the U.S., less than 2% of the land dedicated to cropland and grazing could provide all of our electricity.
  • Covering less than 0.2% of the land on the earth with 10%-efficient solar cells would provide twice the power used by the world.

DOE Goals for Industry Technology Development & Projects:

  • Peak/Intermediate power of 10 cents/kWh by 2012
  • Intermediate power of 7 cents/kWh with 6 hrs storage by 2015
  • Baseload power of 5 cents/kWh with 14 hrs storage by 2020
