  • - A radical idea to get a high-renewable electric grid

    This is an interesting approach to optaining very high penetration of renewables such as photovoltaics and wind.  At present most large installations operate under Power Purchase Agreements (PPA) wherein the economics are based on a sell all output at predetermined prices. This contrasts with standalone systems wherein the system size Read More
  • - Breakthrough Batteries Powering the Era of Clean Electrification

    - Breakthrough Batteries Powering the Era of Clean Electrification Battery Storage Costs Drop Dramatically, Making Way to a New Era. A recent Rocky Mountain Institute (RMI) report continues to confirm that clean electrification through batteries is advancing at impressive rates. Very interesting report: Breakthrough Batteries- Powering the Era of Clean Electrification Read More

This Dish/Stirling solar thermal electric generator was first installed in Jan 1996. It is currently operating at 7.2 KW at 950 W/m2.


Hangar 1 is one of two hangars with a 2300 SF Solarwall and 30 daylighting units installed. The daylighting was installed in 1998 and the Solarwall was installed in 2001.


This 10 KW wind turbine was installed in Feb 2002.


This picture shows both Hangars 1 and 3 with the Solarwalls and a third building with daylighting. The daylighting in the middle building and Hangar 3 was installed in 2000.

Field HouseBarnes Field House has various renewable energy systems installed on it. The main gym has 24 daylighting units installed in 2001. The West facing PV system is 4.8 KW and was installed in 1998. The domestic hot water system on the side of the field house (center of the picture) is 960 SF and was installed in 1981.The ground mounted pool solar system for the indoor pool is 2000 SF and was installed in 1980. They are all operational.
