Environmental concerns continue to surround data centers, and there are a number either approved or planned in Washtenaw County. Supporters of these centers contend there are ways to ensure environmental health while improving the local economy. We’ve explored environmental concerns on WEMU’s "Issues of the Environment." This time around, we’ll get a business perspective on it. Phil Santer is Chief Operating Officer for Ann Arbor SPARK, and he joined WEMU's David Fair to discuss the economics of these data centers.

Today is Earth Day. The theme for Earth Day 2026 is "Our Power, Our Planet." To mark the occasion, we take a look at the power of natural river flow and the benefits and consequences of man-made dams. There are some legislative reforms under consideration in Lansing, and, in the meantime, there are a number of dams in Washtenaw County in different states of functionality. Huron River Watershed Council executive director Rebecca Esselman joined WEMU's David Fair for a look at where the power of policy and funding will lead us in the years ahead.

The Willow Run Airport is among those dealing with PFAS contamination. The Michigan Department of Environment, Great Lakes and Energy has placed the airport within the state’s environmental mitigation efforts tied to aviation contamination. Willow Run will get a $250,000 grant to test and monitor for current pollution and to control or reduce additional contamination and to evaluate clean-up strategies. WEMU's David Fair spoke with EGLE Senior Geologist Eric Larson about the problem and potential solutions to aviation PFAS contamination at Willow Run and around the state.

Most of us will agree; when you combine environmental education with urban forestry and seasonal ecology, and part of the reward is a sweet, sticky, natural treat, you have a winning combination! Making syrup at the neighborhood level: that's the subject of this week's "Issues of the Environment" conversation between Jennie Williams and WEMU's David Fair. Williams is from the Pear Street Collective in Ann Arbor and part of the neighborhood maple sugaring project.

Just about 40 miles from our WEMU studios sits a 440-acre lake plain prairie. It’s called the Sibley Prairie, and you’ll find it in Brownstown Township. It is the largest and highest quality lake plain prairie in Michigan. As such, work is underway to try and permanently preserve this rare ecosystem. Jeff Vornhagen is Director-at-Large of the Huron Valley Chapter of the Michigan Botanical Society. He spoke about the preservation project with WEMU's David Fair.

The Environmental Protection Agency recently announced that the Gelman Sciences 1,4 Dioxane plume has been added to the federal Superfund National Priorities List. After years of effort toward that end, it seemed as though the designation came suddenly and without notice. With a little time behind us now, we’re looking ahead to what’s next in the slow process of cleanup and accountability in a conversation between WEMU's David Fair and Ann Arbor Mayor Christopher Taylor.

While we work on big, community environmental initiatives and goals, we have to remember that sometimes it’s the small, everyday choices we make at home that add up to a big difference. Washtenaw County has robust reuse and recycle programs. With the growing amount of electronics in our lives, we are often left with decisions to make about how best to get rid of those items. WEMU's David Fair talked with Washtenaw County Public Works Director Theo Eggermont about our options and the kind of difference our choices can make.

The picture of our present-day energy use comes from a sort of all-of-the-above menu. We use oil, gas, natural gas, nuclear, wind and solar. Research is underway to determine if the use of hydrogen can be used to significant scale as part of the energy diet. Ann Arbor has become central to the research and discussion on that matter. On this week's "Issues of the Environment," WEMU's David Fair was joined by the Associate Dean for Research at the University of Michigan College of Engineering, Todd Allen. They explored the environmental promise, uncertainties and controversies surrounding hydrogen energy.

The race to eliminate waste is on, and the University of Michigan is working to win! The Campus Race to Zero Waste is the nation’s leading collegiate waste-reduction competition. Michigan won the competition in 2024 but fell short last year. The 2026 competition is underway and runs through the end of March. WEMU's David Fair spoke with U-M Sustainability Program Manager Alison Richardson about the competition and how it benefits the environment.

As we continue the process of mapping out our energy future, there are a number of issues to address, from energy generation and storage to how our electric grids are developed, secured and controlled. State Senator Jeff Irwin is a proponent of virtual power plants as a part of the comprehensive solution. It would divert control of the grids away from the major, centralized utilities. The 15th District Democrat believes virtual power plants can give power to communities in determining their energy futures while saving ratepayers money.
