A 39 kW solar PV array is the newest piece of equipment on Ronningen Dairy Farm in West Concord, MN in rural Goodhue County, and it’s pumping enough energy into the grid to cover about 50% of the dairy’s electricity needs.

Solar is a win-win-win for incentive recipients, economy and environment

 
Ron and Kathy Gray of Kellogg, Minn., applied for the Made in Minnesota Solar Incentive Program in 2015 and were selected to receive the incentive. They had a 9.9 kW rooftop solar system installed on their house, just off Highway 61 in southeastern Minnesota. The system was installed in September 2015 for $40,000.

Over the past year, Metro CERT has supported the energy conservation and development aspect of the Chisago Lakes Area’s community revitalization plan for their entry into the America’s Best Communities (ABC) competition they have been participating in for nearly two years. The Chisago Lakes Area includes the communities of Chisago, Lindstrom, Center City, Shafer, and Taylors Falls.

Over sixty Winona county residents crowded into the Winona City Hall on a recent brisk March Saturday morning to learn the “Seven Steps to a Solar Ready Home.” Because every dollar spent on energy efficiency reduces the size of a needed solar electric generating system energy, efficiency can actually reduce a homeowner’s cost for a solar system by three to five times.

Community solar programs are gaining increasing interest from electric utility customers across the nation. Unlike individual solar PV systems, community shared solar systems, also known as Solar Gardens, create an opportunity for multiple individuals and organizations to receive the benefit of a larger solar installation without requiring it to be located on-site.

The Minnesota Department of Commerce just announced their 2017 Made in Minnesota Solar PV Incentive Program lottery results. This year the program will support 679 new projects and 10.23 MW of capacity—that’s a lot! Minnesota Power’s SolarSense Program also expanded this year.

Every week there has been news of solar installations breaking ground, getting installed, and pumping clean electricity into Minnesota’s grid. It appears we’re definitely in the midst of a solar boom! We pulled together a few of the best recent stories for your perusal.

Interest in reducing the energy consumption of livestock has certainly grown, not only from a consumer’s perspective, but also from producers—for both cost-saving and environmental reasons.

For example, within swine facilities, electricity is used in two major areas. First, for delivering feed and water, and secondly, for removing heat in the summer and providing heat in winter.

Over 40 people stopped by the Sprout Growers and Makers Fair in Little Falls on Saturday, March 25th to learn more about electric vehicles. On display was a sleek black Tesla Model S owned by Jessee Holmes, and a sporty-looking blue 2016 Nissan LEAF owned by Jeff Riegle.

Later this year the nation’s first “integrated” wind and solar hybrid project will begin producing power outside a small city in northwest Minnesota.

Developed by Juhl Energy, Inc., the Red Lake Falls Project combines two 2.3 megawatt (MW) General Electric 116-meter rotor turbines with a 1 MW solar photovoltaic installation.

There is A LOT happening in the world of plug-in electric vehicles (PEVs) here in Minnesota. We asked Jukka Kukkonen with PlugInConnect, LLC, to tell us a bit more.

The Overview

 
“This is a year of great developments in Minnesota,” says Jukka.

No, it isn’t Christmas time again, but you might think that with all the new LED lighting that illuminates the recently remodeled Holiday Gas Station in Grand Marais!

To promote energy efficiency strategies, the Grand Marais Public Utilities Commission issued a rebate to Mike’s Holiday, Inc. for their extensive use of LED technology.

A recent Finance & Commerce article highlighted the installation of a new geothermal system at Cargill Philanthropies in Eden Prairie, Minnesota. The article served as a great reminder that geothermal is an excellent—and often forgotten—energy technology.

The CERTs statewide staff are housed at the University of Minnesota on the St. Paul campus. There is a lot of interesting research happening around here, and when we recently read that researchers were working with high-tech silicon nanoparticles to collect solar energy in windows, man, that got us pretty excited.

OK, it might be a few years away, but hey, still exciting. We spoke with Dr.

LED linear tube lights are an emerging energy-efficient technology. With the popularity of the CERTs Right Light Guide, we decided it was high time to offer some basic guidance on LED tubes.

This is the second version of the guide with slight revisions from the original.
 

Why are people considering LED tubes?

 
Fluorescent lighting is everywhere. Fluorescent lighting is universal.

A new analysis of energy use for 417 public and commercial buildings in Minneapolis reveals that they have the combined potential to save $27 million per year on energy costs by increasing their energy efficiency to reduce consumption by 15 percent.

Friends of the Finland Community had one simple goal in mind: to help the Clair Nelson Finland Community Center become more energy efficient and cost effective. A Northeast CERT Seed Grant helped them get it done!
 

LEDs were the perfect solution

 
Friends of the Finland Community’s aim was to replace ten metal halide light fixtures located on the outside of the building with LED lights.

Ecolibrium3’s Giving Comfort at Home project provides energy efficiency upgrades for Duluth homeowners that may be unable to do so on their own, and the program recently got a boost from a Northeast CERT Seed Grant.
 

Understanding the problem

 
“Duluth housing stock is old, and many of our most vulnerable citizens experience energy poverty, particularly during the winter months.
