Title: Energy Efficiency

Energy Efficiency
Energy Efficiency
  • What is Energy?
  • Energy is the ability to do work.
  • Energy heats homes, runs refrigerators, moves
    cars, lights streets and allows you to run.
  • There are different forms of energy.
  • Renewable Energy is energy that can be made
    quickly, like wind energy.
  • Non-Renewable Energy is energy that takes
    millions of years to be made.

Energy Efficiency
  • Non-renewable energy sources are fossil fuels
    coal, natural oil, and gas.
  • Fossil Fuels are formed from the remains of dead
    plants and animals in special processes that take
    millions of years.
  • Fossil Fuels represent stored energy, stored
    carbon, and stored toxins.

Energy Efficiency
  • MPS gets its electrical energy from Xcel Energy.
  • Xcel Energy uses a mix of non-renewable (80) and
    renewable energy (20) sources to provide
  • This mix includes nuclear, gas, hydo-power and
  • Xcels nuclear energy comes in part from the
    Prairie Island nuclear power plant
  • Much of Xcels hydro-power comes from plants in

Energy Efficiency
  • MPS gets its gas from Center Point.
  • Most of the Center Points gas (85-90) comes
    through pipelines from the Gulf of Mexico. The
    remainder of the gas comes from Canada.
  • Gas runs to schools through pipes.
  • Center Point maintains a gas meter to gauge gas

Energy Efficiency
  • Much of the energy MPS is using comes from fossil
  • Using fossil fuels releases stored carbon and
    other greenhouse gases into the atmosphere.
  • As the amount of greenhouse gases in the
    atmosphere increases so does the temperature of
    the earth.
  • This process is known as climate change.

Energy Efficiency
  • Climate change affects how we all will live.
  • On a warmer earth, icebergs will melt, raising
    sea levels.
  • Do you know people who live by the ocean? Will
    they have to move if the ocean rises?
  • Plants and animals have adapted to live in
    certain climates. If climate change happens too
    quickly, they may not survive.
  • What is your favorite animal? Do you think it
    will survive?

Energy EfficiencyEnvironmental Benefits
  • Burning fossil fuels releases toxins like sulfur
    dioxide, nitrogen dioxide, soot and mercury.
  • If we use less fuel by being energy efficient, we
    will create less pollution.

Energy EfficiencyEnvironmental Benefits
  • Using less energy means that less energy has to
    be made.
  • Making energy from non-renewable sources involves
    mining for coal or drilling for oil.
  • Mining and drilling can be very harmful to the

Surface mining
Energy EfficiencyEnvironmental Benefits
  • By using fewer fossil fuels, we can
  • Stop or lessen climate change
  • Stop acid rain and soot production
  • Hennepin County is committed to reducing
    greenhouse gas emissions by 80 by 2050
  • We can do this by being more EFFICIENT. This
    means being smart and making the best choices
    when using energy.

Energy EfficiencyEducational Benefits
  • Thinking about energy provides an opportunity to
    learn where products come from and what happens
    to them after we finish with them.
  • Visit the EPAs website for educational recycling
    and energy games

  • Visit the Energy Information Administrations
    site for more games and curriculum

Energy EfficiencyEconomic Benefits
  • Being efficient with energy is good for plants,
    animals and you. It also saves money!
  • Energy costs for heating , cooling and lighting
    are very expensive. In most schools, energy
    costs more than books and supplies. Only paying
    salaries costs more.
  • MPS spends 15 million per year on energy costs.

Energy EfficiencyEconomic Benefits
  • Reducing energy use is a good way to save money.
  • It is possible to save money on energy without
    experiencing too much hardship because experts
    estimate that up to 25 of energy used in schools
    is wasted.
  • It is wasted through inefficiencies, like not
    turning off lights, old heating and cooling
    systems, and printing excessively.
  • We can fix this by being more efficient!

Energy EfficiencyWhat MPS is Doing?
  • MPS is taking steps to be energy efficient
  • Upgraded more than 141 boilers, so they use less
    energy to heat water
  • Preventive maintenance program to improve heating
    and cooling efficiency
  • Retrofit systems using more energy efficient
    technology while aggressively pursuing rebates to
    offset the costs of the upgrades

Energy Efficiency
  • More Steps the district is taking...
  • Working to improve monitoring systems to find
    ways to reduce energy consumption even more.
  • Improving bus efficiency by retrofitting 40 of
    MPS-owned diesel buses with special recirculation
    valves to significantly reduce emissions

Energy EfficiencyHow to be Energy efficient
  • Here are some simple ways you can reduce energy
  • Lighting accounts for 50 of energy costs.
  • Turn off lights when they are not in use.
  • Open the blinds during the day to use natural
  • Close the blinds at night to keep the room warm.

Energy EfficiencyHow to be Energy efficient
  • Powering the monitor accounts for 50 of the
    energy a computer uses.
  • Turn your computer monitor to off or sleep
    when it is not in use.
  • Do NOT shut down any Mac Computers or Windows
    computers in labs. IT services performs updates
    on these computers after hours, and has already
    programmed them to automatically go to sleep
  • Turn off printers, copiers and other office
    equipment at the end of every day.
  • Turn off and unplug electronics and personal

Energy EfficiencyHow to be Energy Efficient
  • Use MPS Green Reports to find out every
    buildings carbon footprint.
  • With this information, you can find out where
    energy savings can be made.

Energy EfficiencyHow to be Energy Efficient
  • Have fun with Green Reports!
  • You could Have a contest to find out whose more
    efficient middle-schoolers or the elementary

Energy EfficiencyHow to Be Energy Efficient
  • Water conservation is a part of energy savings
    and efficiency.
  • Save water by
  • Not letting water run
  • When washing your hands turn the water on to wet
    them and then turn it off while soaping.
  • Reporting leaks to maintenance staff immediately
  • Maximizing natural cover in outdoor landscaping

Energy EfficiencyHow to Be Energy Efficient
  • Energy efficiency improves our environment and
    saves money.
  • Little steps and big steps both count.
