Caption: Jim Winkle, a systems programmer with the Division of Information Technology (DoIT) at the University of Wisconsin-Madison, thinks of energy conservation while posing under the light of a sunny day outside his Madison home on June 12, 2007. Winkle recently installed a solar panel system at his house that is designed to support his household's annual 2,000 kilowatt-hours energy need.

Caption: Two computer-generated graphics display the daily solar energy collected at the Madison home of Jim Winkle, a systems programmer with the Division of Information Technology (DoIT) at the University of Wisconsin-Madison. The graph at top, captured on June 2, 2007, illustrates the level of solar energy collected throughout a partly cloudy day. The graph at bottom, captured on June 9, 2007, illustrates a "near-perfect solar day" and shows maximum sun exposure peaking about 1 p.m. with only a brief period of reduced solar energy late in the afternoon, likely caused by either passing clouds or late afternoon shadows temporarily cast upon the solar panels.
