Kaua`i Renewable Energy Conference Miles Kubo President/COO September 8, 28
Energy Conservation is consciousness and action Turn off a light Walk a flight of stairs Shut down computers Unplug phantom loads Reduce, Recycle, Reuse Do: Energy Efficiency
Energy Efficiency is action without consciousness Low-wattage lighting High-efficiency equipment Sensors and controls Demand limiting Hybrid vehicles Reuse waste heat
Sustainability Energy Assessments Rebates Energy Conservation Capital Budgeting g Savings Efficiency Energy Finance ECMs Renewable Energy Solving the Puzzle

-Rules - Just because it sounds too good to be true, doesn t mean it is. All capital improvement projects are not equal. Preserve capital improvement budgets for other essentials. If you think you can t afford it, Think Again!
Remember Energy is Essential your Demand will Grow Deal with it!
