Energy

Campuses like UW Oshkosh use a lot of energy for electricity, heating, cooling, and transportation. We are committed to energy management strategies that reduce energy consumption and greenhouse gas emissions, save money, and reduce reliance on foreign energy. Energy conservation is our first commitment, because it reduces the amount of energy we need to do what we do. In today's economy the cheapest kilowatts and therms are the ones you don't use.

Our strategy

  • Perform retrofits and upgrades of building systems to improve energy efficiency (see infrastructure)
  • Construct new buildings and Renovate existing buildings with energy efficiency in mind
  • Produce renewable energy on campus and purchase renewable energy through renewable energy credits (RECs)

Green Power Purchases

On May 13, 2003 UW-Oshkosh became the first Wisconsin university to join the Environmental Protection Agency’s Green Power Partnership, a commitment to purchase alternative energy. 

  • Presented with an EPA Leadership award (2003)

 In 2006, UWO increased its annual green power commitment from 4% to 11% of total power purchased

  • Purchase was equivalent to 288,800 kilowatt hours (kWh) per month for 12 months
  • Today, 16% of total power purchased comes from renewable sources, mostly wind

Performance Contracts

UW Oshkosh has committed to the statewide program designed to increase energy efficiency and provide other economic and environmental benefits. All work is performed and paid for by the contractor and payments are made through energy savings. Energy savings as a result of performance contracts is now above 20% -- meaning that our energy use dropped by more than 20% from the pre-contract year.

Renewable Energy

Wind Power

  • Energy produced by wind makes up the majority of power acquired through green power purchases (16% of total consumption)

Solar Power

In 2010, UW Oshkosh installed the first photovoltaic panels to generate electricity on campus. Learn how many watts per hour the panels are currently generating. To date, we have solar installations on the following buildings:

  • Albee Hall
    • Solar Thermal: 64 panels, 7,692 Therms/year
    • Heat the indoor swimming pool
  • Blackhawk Commons
    • Solar Thermal: 24 panels, 1,878 Therms/year
    • Hot water for dishwashers and taps
  • Sage Hall
    • Solar Thermal: 60 panels, 4,745 Therms/year
    • Photovoltaic (PV): 188 rooftop panels, 46,000 kWh/year
    • Three pole-mounted PV tracking arrays, each unit = 2.5 kW
  • Student Success Center
    • Photovoltaic (PV): 20 kW
  • Taylor Residence Hall
    • Solar Thermal: 16 panels, 1,300 Therms/year
    • Hot water
  • Heating Plant
    • Solar Thermal: 16 panels, 1,910 Therms/year
    • Pre-heat the water that is heated by the furnaces for steam production

Biomass

Types on UW Oshkosh campus:

Dry Fermentation Anaerobic Digester (BD1)

  • First of its kind in North America
  • Dry biodigesters use fewer resources such as water which reduces impact
  • Located on campus, the plant produces methane gas from organic wastes including food, municipal yards waste, and farm bedding
  • Food waste from campus cafeterias and yard waste from grounds are diverted from landfills to this facility
  • BD1 processes more than 11,000 tons of organic waste annually
  • At full capacity, the is equipped generate 10% of campus electricity needs and will 
  • Thermal energy will heat Facilities Services, saving campus some $20,000/year

Small Farm Digester (Allen Farms)

  • The Allen Farms digester uses the manure from 135 cows and other farm waste to make methane gas to generate electricity and thermal heat
  • This facility generates 64 kWh of electricity and thermal energy to power and heat the farm
  • The technology may be scaled to suit small to medium sized farms of various sizes
  • A recent grant from the USDA is being used to educate regional farmers about the technology in hopes of increasing the numbers of such facilities in the state of Wisconsin and the country

Large Farm Wet Digester (Rosendale Digester)

  • Located at Rosendale Dairy, Wisconsin’s largest dairy farm
  • From the manure of 9,000 cows, the facility uses 110,000 tons of manure annually to make methane gas
  • Electricity produced from a 1.4 MW generator is sold to Alliant Energy and is equipped to generate 40% of UWO's electricity needs

Geothermal

  • Student Success Center
  • Horizon Village
