Environmental Benefits
We have reduced our consumption by:
12.6 million kWh of Electricity
1,074,316 CCFs of Natural Gas
The Greenhouse Gas Reductions equate to:
Preventing the release of 9,142
Metric Tons of CO2 into the atmosphere
Removing 1,905 automobiles
for an entire year
234,409 tree seedlings
grown for 10 years

MPS Exceeds Cenergistic Expectations
At the start of the program, Cenergistic projected savings by year.
To date, our net savings of $2,177,733 has exceeded what
Cenergistic projected would take more than 10 years to achieve.

‘Repair or Replace’ Projects
As repairs or replacement of items that use
energy arise, energy efficient products are
incorporated.
Energy efficient exhaust fans and roof top heating units
replace older versions, when needed.
Exterior light timers replaced with astronomical digital
timers, when needed.
Broken light fixtures replaced with LED fixtures.

What’s next? - SOLAR!
MPS is committed to continuing to reduce energy consumption and saving money
Solar energy makes sense
- New roofs on school
- Government and Utility incentives make it affordable
No up-front capital costs
MPS/City will lease the roof space for 20 years – solar is installed and the units maintained by the developer
MPS purchases the energy at a reduced cost
