Denver Public Schools, MP2 Capital, Namasté Solar, and Oak Leaf Energy Partners have partnered together to bring solar electricity to sixteen Denver Public Schools in 2010! The overall project will consist of fifteen schools each receiving a single 100kW solar photovoltaic system and one additional school receiving a 300kW solar photovoltaic system. The first project is currently under way and all 16 projects are expected to be complete by December of 2010. Through a Power Purchase Agreement (PPA) agreement with MP2 Capital, Denver Public Schools will not be required to pay up-front costs for the systems, and will realize an overall cost savings on their electricity bills.

In addition to the solar electricity that will be provided by the abundant sunshine we have here in Colorado, Namasté Solar will also work with a teaching representative from each of the 16 schools to develop a solar specific “Solar Champion” curriculum that can be used each school year to educate students about the benefits of solar electricity and the technology that has been integrated with their school. As part of the curriculum, each school’s solar PV system will include a web-based monitoring system that will allow for real time viewing of the solar electricity and environmental benefits that are produced on the schools.

*The amount of carbon offset by buying a certain amount of REC’s is calculated based on the state average carbon dioxide emissions coefficient for electric utilities, 1997-99, as published in “U.S. Department of Energy and U.S. Energy Information Administration Form EIA-1605 (2001), Voluntary Reporting of Greenhouse Gasses, Appendix C: Adjusted Electricity Emissions Factors by State.” For the Rocky Mountain Region, each of the ten states’ carbon emissions per kilowatt-hour is calculated and then averaged for the entire region. The pounds of carbon dioxide produced for each kilowatt-hour of electricity generated in Colorado is 2.048.

**The number of cars removed from the road is calculated based on driving a car that gets 21.4 mpg for 11,904 miles (the national average) per year. (The average miles driven per year is derived from the “Monthly Energy Review, February 2001” published by the Energy Information Administration. The figure averages car miles driven and SUV miles driven.) This yields 556

gallons of gasoline used. Pounds of CO2 produced per gallon of gasoline burned is 19.564 (from “Instructions for Form EIA 1605B, Voluntary Reporting of Greenhouse Gas Emissions, Appendix B,” U.S. Department of Energy and the Energy Information Administration.) This driving thus produces 10,883 pounds of CO2 per year. This amount is then correlated to the amount of CO2 produced by electricity generation averaged over the Rocky Mountain Region.

***The estimated amount of CO2 that a tree will take up in a year is 26 pounds. This is based on a figure from American Forests as cited by the Natural Resources Defense Council, “OnEarth Magazine,” Winter, 2005 (http://www.nrdc.org/onearth/05win/livgreen2.asp) Actual amounts of atmospheric CO2 taken up by trees varies with the age of the tree, the species, local climate, the tree’s health, etc.
