4. Energy Efficiency Solves Problems
• Lower monthly energy consumption
• Lower monthly energy costs
• Solve comfort problems like drafts and cold spots
• Prevent issues like ice dams
• Address uncontrolled moisture and ventilation problems
…all through efficiency improvement projects
(and earn rebates and other incentives and use competitive
financing, if needed)

5. Energy Efficiency Means What Again?
Using less energy to provide the same service
Energy efficient homes have:
• Fully insulated attic & walls
• Efficient lighting and appliances
• Efficient heating system
• Efficient water heater

6. Energy Efficiency: The Smart Step Toward Solar
The cheapest energy is the energy that you do not use.
increases the % of your home
that is powered by solar energy.
Reducing the amount
of energy you consume,

Minnesota Key Energy Policies
1. Conservation Improvement Program (electric and gas):
o Requires utilities to spend a certain amount of annual revenue
on efficiency investments (Gas .5%, Electric 1.5%, Xcel 2%)
2. Net Metering (electric): Customers must be compensated for
electricity they generate and feed into the local utility’s grid
(1,000 kW limit for investor-owned utilities, 40 kW limit for coops
and muni’s)
3. Renewable Energy Standards (electric):
o Xcel Energy – generate/procure 30% by 2020, plus 1.5% solar
o Investor-owned utilities – generate/procure 25% by 2025, plus
1.5% solar
o Cooperative and municipal utilities – generate/procure 25% by
2025

20. The Solar PV Future

21. Is there Enough Sunlight?

22. Is My Site Good For Solar?
• Do I have a south facing roof or location?
• Are there shade issues?
• When do I anticipate re-roofing?
• Is my roof structurally sound?
• Am I going to be in the
home for a while?
• Is my home energy
efficient?
… talk to a solar installer!
