◦ Develop leadership, community-building, and problem-solving skills
◦ Increase awareness of career, economic, and entrepreneurial opportunities
◦ Increase knowledge about energy issues & opportunities
◦ Create sustainable communities
Energy Audit—Mankato West◦ Conducted an electrical
energy usage audit
◦ Determined that lighting was the largest
◦ Changed out 32 watt bulbs that last 24,000 hours to 28 watt bulbs that last 55,000 hours
◦ Replaced 731 light bulbs and will save 165,000 kWH, equating to $19,000 over the life of the bulbs
Pop Can Solar Heaters—Westbrook-Walnut Grove
◦ Got the idea from the internet: absorb sunlight with pop cans and produce hot air
◦ Goal was to get outgoing air from heaters to 110°F or more to reduce heating costs in city buildings and ice fishing shanties
◦ Accomplished 25°F change in medium heater
◦ Project enabled students to learn about thermal energy, specific heat, convection, conduction, and infiltration
Pop Can Solar Heaters cont’d◦ Process:
◦ Collected pop cans from school recycling bins, glued them together in a line, and painted them black
◦ Built wood frames 42 7/8 inch x 21 ¼ inch in size
◦ Secured Plexiglas on top of wood frame
◦ Connected computer fan powered by solar panel to the frame
◦ Using Styrofoam around the inside of the frame for insulation
