Advanced Energy Basics
• Non-profit public benefits corporation funded by electric bill surcharge.
• Formed in 1980 by the NC Public Utilities Commission.
• Focus on energy efficiency, electrotechnologies and green power.
Outline
• Efficiency and Air Quality• Efficiency and Technology +
Economics• Renewables• Bringing it Together: Economics
Source of Air Quality Problems
• Conversion of energy into work and byproducts
• Can clean the conversion byproducts
What “they” should do• Can reduce consumption What “we” can do

CriticalGap
Efficiency: Residential
• Building Codes• High Performance Homes
Cambridge Homes
• Winner of National Association of Home Builders Gold Medal for incorporating High Performance into production
• Guaranteed Energy (25-50% less heating and cooling)
• Greater profits
High Performance Homes?Quality Control!!!
• Air Barrier• Insulation• Windows
• HVAC• Ventilation• Combustion
Safety
Emissions Impact
• 3.5 million households in NC• Save 3,300 kWh/household/year• 4,610 pounds CO2 reduction• 16 million pounds CO2 reduction in
NC
Economics
• Benefit to builder is $$$• Benefit to buyer is $$$• Benefit to community is reduced
energy consumption and emissions
Industry
• Motors: As much as 70% of electricity used in industry goes through a motor
• Slight increase in motor efficiency can save lots of energy
• Key is reliability
Motor Efficiency and AQ
• 100 hp motor• 1% efficiency gain = 5,500 kWh
savings• 7,700 pounds CO2 reduction per
year
Motor Efficiency and AQ
• 100 hp motor• 1% efficiency gain = 5,500 kWh
savings• 7,700 pounds CO2 reduction per
year
• Only $431 per year savings
Key Barriers• Lack of awareness: Perception
by plant management that energy saving opportunities are small and not cost-effective For a 250 hp pumping
system operating for 10 years at $0.05/kWh…
Purchase Cost = $28,000
Energy Costs = $750,000
Maintenance & Misc. Costs = $260,000
Purchase cost is just the tip of the iceberg!
• Lack of Corporate Energy Management: Energy not part of most corporation’s business strategy
• Limited plant staff: Plant engineering has little time to find energy saving opportunities
• First cost thinking: Lack of recognition by supplier and customer that energy costs arekey part of pump’s life cycle costs
Industry
• Electrotechnologies:• Powder coating – VOC reduction,
improved product quality, improved productivity, improved profits
• Process heating – better control
Industrial Economics
• Companies MUST make money• Energy consumption is small part
of their picture• Find the company’s “pain” and
help fix it. Solution often reduces emissions and saves energy
Transportation
• Hybrid Electric School Bus
• Produced in North Carolina
• Energy savings• Emissions reductions• Jobs
Renewable Energy
• NC GreenPower• Wind, solar• Biomass• Landfill gas
Bringing It Together
• No single silver bullet• Figure out how to make money or
ease pain • Make their job easier• Reduce costs
