Is this Tomorrow’s World?
Domestic Reserves in Decline
$7.00+ a Gallon Gasoline
Rise in Energy Poverty
60% CO2 Reduction
By 2050
Unsecured Energy Supply
20% gap in Electricity Generation vs. Demand

Today’s Perspective:
Rejected Energy From Electric Generation Is Equal to All of the Oil
Imported to the US Every Year
“The energy lost in the United States from
wasted heat in the utility sector is greater
than the total energy use of Japan”.

Challenge: Rejected Energy & Wasted Heat
Can it be Captured & Used?
Yes, Through the Combined Heat & Power (CHP) Process

What If CHP Represented 20% of US Generating
Capacity in 2030?
20 %
Same as Taking
61% of U.S. Car
Fleet Off of the
Road
20 % of U.S. Electricity Generating Capacity 240,900 MW
Annual Energy Savings 5.3 Quads
Annual CO2 Reduction 848 MMT
Annual Carbon Reduction 231 MMT
Number of Car Equivalents Taken Off Road 154 million

Combined Heat & Power – Barriers
Where is Support Needed on the Path to 20% Capacity in 2030?
These Determine
Key Support Barrier Hurdle Rate – and
“Investment
Decisions”
Incentives –
“As Good As Base” Business Model rate structure
Lower Cost, Better Technologies Energy Prices
DOE - “Better Ingredients and new Recipes” (electrical vs fuel)
Tax Policy –
Drive “Green” Capital Investment e.g. depreciation
Grid Transformation Grid Connections
Smart Grid – Distributed Energy New standards
Environmental –
Capture CO2 Benefits Recognition - Incentives 20% CHP capacity avoids
