Mr. Great Lakes (Jeff Kart). As heard in Bay City, Michigan, on Fridays at 9 a.m. on Delta College Q-90.1 FM.

The Feb. 8, 2013, Environment Report:

1 – Solar shingles sound great, sure.

They can save you energy, sure.

But for how much?

The Dow Chemical Co., which manufactures Powerhouse Solar Shingles in Midland, has developed a cost and savings estimator, based on your state, home size and energy savings goal.

For example, you can look at a 2,500-square-foot home in Michigan, based on an energy savings goal of 20 percent.

Asphalt shingles will cost about $9,000. Powerhouse Solar Shingles will cost you about an extra $11,000 for the same home.

But energy savings are estimated to be more than $14,000 over 25 years. The solar shingles also are estimated to increase a home’s value by another $11,000.

The estimator will point you to contacts for more specific information on your home, and authorized dealers, including Cobblestone Homes in Linwood.

2 – The Super Bowl may be over, but the Great Lakes Bowl is Saturday (Feb. 9).

The 2013 Great Lakes Bowl in Ann Arbor will bring together 16 teams from high schools and junior high schools in Michigan and Ohio to compete for a spot in National Ocean Sciences Bowl.

This year, there are 16 teams from 14 schools participating. They include Standish-Sterling Central High School in Standish.

The Saturday event is one of 25 regional competitions being held around the U.S. this month.

Each five-student team will compete through quick-answer buzzer questions and more complex team challenge questions focused on freshwater and saltwater.

Categories include physical oceanography, biology, chemistry, geography, geology, marine policy, social sciences, and technology related to the Great Lakes and oceans.

The Great Lakes Bowl will award cash, trophies, medals and other prizes to top finishers, according to a sponsor, Michigan Sea Grant.

The top team from each regional competition will advance to the National Ocean Sciences Bowl finals competition, to be held this year in April in Milwaukee.

3 – How much trash did you throw away last year?

In Bay County, the Whitefeather Landfill in Pinconning Township took in more than 401,000 cubic yards of waste, mostly from municipal and commercial sources, and mostly from Bay and Saginaw counties.

The information comes from Michigan’s annual report on solid waste for fiscal year 2012, ending Sept. 30.

In Michigan landfills overall, there was a 3.1 percent decrease in solid waste disposed of in 2012 compared to the previous year.

Waste imported from other states and Canada went down by almost 2 percent. Still, Canada remains as the largest source of waste imports into Michigan, representing 15.3 percent of all waste disposed of in state landfills, according to the state Department of Environmental Quality.

At current rates, it’s estimated that Michigan landfills will be filled in about 28 years. Whitefeather in Bay County has about 23 years of capacity left.
