Happy St. Patrick’s Day! In an effort to be more “green” today and every day, we now have a compost tumbler on the west side of the National Soybean Research Center, thanks to SSC funding. This is the first publicly-accessible compost drop-off on campus!

Please feel free to take advantage of this opportunity to sustainably dispose of your fruit/vegetable scraps (without stickers), tea bags, coffee grounds/filters, eggshells, shredded paper etc. While this 60-gallon compost tumbler is housed at the NSRC building, this drop-off opportunity is available to all. Simply unscrew either end of the tumbler and drop your items inside. Attached are several photos of the location and setup, as well as a list of the acceptable/unacceptable items. 

The end-product will ultimately be used to fertilize a pollinator garden at NSRC. More details to come. 

Izabelle, Morgan, and Brent met to discuss progress on the Meadow at Orchard Downs. Izabelle is going to select the preferred tools to purchase, and meet with Morgan on site on Sunday, 3/14/21, to put stakes around the outline of the first section to work on. Brent is going to get a work order set up to be able to place orders.

Renewable energy at the UI "How much power is each of the renewable (University of Illinois) sources generating? How many houses can each provide power for? Are there plans to add more than what we currently have? How many years does it take for the cost of each to be paid off? We have a growing interest in this and many homes now also have this."

Morgan White, the UI's associate director of Facilities & Services for sustainability, has all your answers.

As for power generation, she said that the UI's "on-campus solar arrays are now capable of producing over 25,000 megawatt-hours (MWh) per year and we purchase an additional 25,000 MWh/year from an off-campus wind farm in Illinois.

"For a more comprehensive answer:

"The (Illinois Climate Action Plan) 2020, objective 2.3.1 is: 'Use at least 140,000 MWh/year of clean power by FY25.' This objective is about clean power, which is different from clean thermal energy. As of 2020, there are three types of clean power options being pursued or used on campus.

"1. Solar Energy on Campus: installing solar photovoltaic panels on campus property

"2. Wind Energy on Campus: installing wind turbine generators on campus property

"3. Power Purchase Agreements for Clean Energy: purchasing solar or wind power from off-campus

"FYI, Solar Farm 2.0 is projected to produce 20,000,000 kWh/year. It began production at the end of January, so there will only be 5 of 12 months production in the FY21 totals (this current fiscal year)."

As for the number of houses each can provide power for, White said, "At Facilities & Services, we use the US Energy Information Administration (EIA) for the average power use in an American home. It currently says, 'In 2019, the average annual electricity consumption for a U.S. residential utility customer was 10,649 kilowatthours (kWh).”

"Thus, the FY20 clean power use on campus (30,635,993 kWh) was the equivalent of the power needed for 2,876 houses. Once Solar Farm 2.0 is operating for an entire year, that will be about 50,000,000 kWh/year of clean power use on campus, which is the equivalent to the power needed for 4,717 houses."

And about whether more generation will be added, she said: "The recently released Illinois Climate Action Plan 2020 (iCAP 2020) includes a goal for increasing clean power use to 140,000 MWh/year by FY25. We are currently having internal discussions at the University of Illinois about initiating a large off-campus solar power purchase agreement to meet this goal. We are also continuing to pursue clean thermal energy solutions, such as geothermal. Additionally, large construction projects on campus are required by the state law to be LEED certified, and this will often entail the addition of clean energy systems for individual buildings."

The payback period for each of these systems varies widely due to several factors, she said.

"For example, the geothermal system for the Campus Instructional Facility is projected to pay for itself in 28 years, while Solar Farm 2.0 is saving money in year one," said White. "For local projects off-campus these programs are very helpful: the Solar Urbana-Champaign program typically finds solar installations to pay for themselves in six or seven years, and the Geothermal Urbana-Champaign program typically finds a geothermal system at a residential home can pay for itself within 10 years."

Sol Systems published a blog today sharing information about the collaborations with the UIUC Sustainability, Energy, and Environment Fellows program, the campus-wide minor in sustainability.  

"This past week, two groups of students from the University of Illinois Urbana-Champaign presented to Sol Systems regarding their findings through the university’s sustainability minor capstone course. The students conducted an emissions audit for supply chain and land-usage for the university’s second utility-scale solar project, Solar Farm 2.0, a 54-acre, 12.3 MW dc system on the Urbana campus that is being developed by Sol Systems. The presentation and partnership served as part of Sol’s sustainability initiatives and acts as the foundation for building Sol’s framework for future and current solar project developments...."
