Pennsylvania Energy: Energy from the Sun

This video advises viewers who want to decrease energy consumption to take a lesson from a cat lying in the sun. The sun's energy, an engineering design professor explains, can be harnessed for human needs in three ways: convert solar energy to heat, heat hot water, or convert solar energy to electricity.

One example in the video focuses on how solar panels helped a school to decrease electricity costs, and taught students they could make a difference. Another is how a prison heated water for showers and laundry with solar panels. Both the school and prison significantly decreased energy consumption.
