Xcel Energy recently announced the 20 recipients of $30 million in renewable energy grants, seven of which are solar projects.
The projects vary in size and location throughout the state of Minnesota as well as one in Wisconsin. The largest project will be a 1.18 megawatt solar installation at a Terminal One parking ramp at the Minneapolis-St. Paul International Airport. Other projects include locations at the St. Paul Midway Target, Edison High School, and the Sisters of Notre Dame School in Mankato.

The tiny Minnesota farming town of Milan may be small in terms of population—about 1,000 for the greater Milan area—but it is big time when it comes to energy efficiency.
The west central town, through its Greater Milan Initiative, committed in 2009 to develop a long-term community culture of reducing energy usage and costs and promoting renewable energy to end users. Milan adopted the nation’s first rural “Sustainable Energy Utility,” a community-based model that provides a point of contact for residents, businesses and organizations to learn about and implement energy efficiency.
To help demonstrate sustainable behavior, the nonprofit Greater Milan Initiative partnered with Otter Tail Power Company, the state, and local contractors to provide cost-effective improvements to its community center. The result has been a thriving community center that has tripled its usage, while...

The Energy Center of Wisconsin was awarded a 2011 Conservation and Applied Research Grant from the Department of Commerce, Division of Energy Resources for field testing drainwater heat recovery (DHR) systems in Commercial Buildings.
DHR systems include replacing a portion of vertical drain pipe with a heat exchanger module. The heat exchanger module can consist of a copper vertical pipe (drain line) to match the diameter of drain pipe being replace, surrounded by a coiling smaller diameter copper pipe (supply line). The system works when warm water (say, from a shower, washing machine, or dish wash station) flows vertically down through the drain line and cool water flows upward through the supply line and onto a water heater for additional heating.
CERTs recently sat in on a webinar from the Energy Center about the nearly completed study. The main take-aways are as follows:...

Many businesses, including large commercial and industrial (C&I) facilities, have the potential to realize significant energy savings from untapped improvements in operations and maintenance (O&M) practices. However, financial obligations, time and staffing constraints, and existing institutional practices create significant barriers to implementation.
Many customers also lack experience with energy and resource accounting tools for benchmarking the efficiency of their facilities, and for tracking progress of efficiency and conservation efforts. An economic environment characterized by slow growth and high uncertainty can contribute to the reluctance to make significant capital outlays for energy efficiency upgrades. These factors increase the urgency for utility Conservation Improvement Programs (CIPs) to assist customers in achieving energy savings from low/no-cost (LC/NC)...

It was a beautiful day to tour the state’s largest solar photovoltaic (PV) installation on July 19th, 2013 in Slayton, Minnesota. With the sun high and bright in the sky and only puffy white clouds to speak of, 35 members of SW/WC CERT toured the 7.5 football fields worth of solar panels working at maximum capacity. Keep reading to learn more and see lots of photos.
The day started with a informal lunch at the town’s Pizza Ranch at noon. Members of the CERTs tour, as well as members of the day’s previous tours, gathered in the East room. After a quick introduction by Joel Haskard (CERTs Co-Director) and Jeff Vetsch (West Central CERT Coordinator), Brian Ross of C.R. Planning took the stage to explain some of the changes in the recent Minnesota legislation concerning solar. Click here to view the...

On those summer days that are particularly hot and sticky, the use of a ceiling fan in conjunction with air conditioning or natural ventilation may be your best choice to cool things down. The wind chill effect that increased air movement creates on skin means that turning on a ceiling fan will allow you to raise your home thermostat setting about 4 degrees with no reduction in comfort. From a conservation standpoint, it is important to keep in mind that fans should be turned off as you leave the room—fans cool people (through the wind chill effect), not rooms.
The U.S. Department of Energy recommends that ceiling fans should not be used in rooms any shorter than eight feet high. Also, blades should never come closer than 8 inches from the ceiling and 18 inches from the nearest wall. Ceiling fans are a great choice for the summer months, but will likely not reduce your heating...

Energy Secretary Ernest Moniz recently highlighted the continued growth of electric vehicle sales—doubling in the first 6 months of 2013 compared to the same period in 2012—as the Energy Department released its most recent pricing data showing the low cost of fueling on electricity. The eGallon, a quick and simple way for consumers to compare the costs of fueling electric vehicles vs. driving on gasoline, rose slightly to $1.18 from $1.14 in the latest monthly numbers, but remains far below the $3.49 cost of a gallon of gasoline.
“More and more Americans are taking advantage of the low and stable price of electricity as a transportation fuel, and that’s very good news for our economy as well as the environment,” said Energy Secretary Ernest Moniz. “As the market continues to grow, electric vehicles will play a key role in our effort to reduce air pollution and slow the...

A new report has been published that offers guidance to building officials and solar installers regarding the need for structural review of planned residential solar installations.
The report, issued by the Minnesota Department of Commerce in cooperation with the Department of Labor and Industry, developed standard load tables that outline limitations for placement of residential rooftop solar electric and solar thermal systems on existing single and multifamily dwellings. The tables encourage safe and structurally reliable systems while reducing costs associated with unnecessary structural review for many residential applications.
The cost to have a structural review of existing conditions for proposed solar installations can be a real barrier to adoption, according to the...

Renewable energy will be prominently featured at this year’s Home Energy exhibit at the 2013 Minnesota State Fair, with several displays dedicated to solar and wind energy. The Home Energy exhibit, located in the Eco Experience at the north end of the fairgrounds, is intended to educate fairgoers about a wide range of energy conservation and energy efficiency measures and renewable energy opportunities.
The exhibit’s solar energy area is a partnership with the Minnesota Renewable Energy Society and will include four new displays:
A Solar Electricity display that demonstrates the benefits of generating solar energy for electricity and how solar photovoltaic panels provide electricity to your house.
Solar Water Heating display that...
