The Energy Problem
•
•
•
•
•
•
•
•
Air pollution
Global warming
Limited resources
Rising energy prices
Shortfalls in supply
Power grid constraints
Reliance on imported oil
Marketplace more complex
The Air Quality Connection
• Direct & Obvious Impact
– Burning gasoline, diesel, oil
– Direct air emissions
– User can see & smell it
• Indirect impact
–
–
–
–
Electricity consumption
User is disconnected from pollution source
Power plant emissions are largely unseen
Environmental impact not obvious to the user
Carbon Intensity
350
Significant source of pollution but
largely unseen by end-user

The Bottom Line
• Reducing energy consumption:
–
–
–
–
–
–
Reduces emission of greenhouse gases
Reduces emission of air pollutants
Reduces cost of purchased energy (avoided)
Reduces waste of natural resources
Reduces strain on supply infrastructure
Puts downward pressure on energy prices
It’s all good!
(but it’s not all easy)
We get it…Now what?
• We need to change our thinking, priorities, ACTIONS….TODAY!
New Jersey is Taking Action
• Governor Corzine’s Executive orders
– Increase energy efficiency in State government
– Reduce greenhouse gas emissions state-wide
• Established Office of Energy Savings (OES)
– located within Department of the Treasury
– Includes director and staff of three managers
– Driving energy conservation, cost reduction, and
reduced emissions across all State agencies
– Raising visibility & accountability for all agencies
– Set 5-Year goal
• Reduce energy consumption by 10%
State Gov’t Energy Profile
•
•
•
•
•
•
•
•
Consuming an est. 8.3 trillion BTUs annually
~ 20,000–30,000 electric & gas bills/year
~ 80,000 employees (energy consumers)
17 State departments
> 50 State agencies
~ 300 facilities
> 4,000 buildings
> 12,000 vehicles
State Gov’t Emission Profile
Carbon Emissions by Energy Use (tons CO2)
16%
Vehicle Fleet
State Facilities
838,000 tons CO2*
84%
* Based on estimated consumption volumes
Energy Management Strategy
Executive Orders
Energy Tracking System
Goals for each agency
Continuous monitoring
Continuous reporting
Continuous improvement
MEASURABLE RESULTS
OES Initiatives Underway
•
•
•
•
•
•
•
Evaluating State energy usage & cost
Forming department energy teams
Taking immediate energy conservation actions
EE project review & ranking
Developing an Energy Tracking System (ETS)
Reviewing State vehicle fleet
Exploring ways to reduce energy consumption for
computers and office equipment (printers, faxes, copiers)
• Evaluating & Redeveloping the State recycling program
• Investigating proposed legislation to allow long-term
energy-savings contracts to deliver cleaner air now
• Building OES website to provide information, contacts
Immediate Conservation Actions
• Initial focus on Trenton facilities
• Buildings owned/occupied by
State agencies
• Working with Div. of Property Mgt.
& Construction (DPMC) to review
building operations & maintenance
• Adjusting control systems to reduce energy consumption
for lighting, heating/cooling, motors, etc.
• Adjustments made to date are expected to deliver:
–
–
–
–
Reduced energy consumption of 3.5 million kWh annually
Reduced air emissions of 1,900 tons CO2
Equivalent to removing 278 cars or planting 374 acres of trees
$385,000 cost reduction benefit
Conservation Opportunities
• Raise awareness across all agencies
• Communications to reach all employees
– Make it personal
• Education about energy-environment link
• Point out office & home opportunities
– Conservation, energy efficiency, renewable, savings
• Agencies share ownership to make it work
• Keep it fresh and interesting
EE Project Opportunities
• Lighting Retrofits
• Building controls
• HVAC
– Boiler upgrades
– Chillers
– High efficiency roof top units
• Fuel switching
– Phasing out use of fuel oil
• Combined Heat & Power
• Renewable
– Cost-effective applications for PV, landfill gas, etc.
We Must Eliminate Energy Waste
•
•
•
•
•
•
•
•
•
•
•
Leaving lights on when not needed
Leaving computers running when not being used
Redundant printing, copying, faxing equipment
Leaving doors and windows open
Setting heating/cooling temps too high/low
Failing to use set-back temperature settings
Failing to replace air filters when dirty
Failing to maintain equipment
Buying less efficient products & equipment
Buying vehicles that are too big, not energy efficient
Failing to maximize waste recycling
