Frequently Asked Questions
How much can efficiency improvements save?
Typical improvements save 10-30% annually. LED lighting saves 75%, HVAC upgrades 15-20%, insulation 10-15%.
What is payback period?
Time for savings to equal upgrade cost. A $1000 upgrade saving $200/year has 5-year payback.
How do I estimate usage reduction?
Research typical savings for specific upgrades, or consult energy audits. Conservative estimates are safer.
Should I include rebates and tax credits?
Yes, many jurisdictions offer incentives. Check local utility and government programs for details.
