Back in April 2012, Oklahoma State University concluded an LED lighting project with a dairy farm. Much like The Minnesota Project’s LED poultry project, the OSU researchers sought to test the LED lights’ energy savings potential and the durability of the bulbs.
In addition, they tracked cow health and milk productivity out of concern the LEDs might harm the dairy cows. The researchers were pleasantly surprised to find the dairy cows increased milk production by 6% with no negative side effects. In other words, the dairy farmer was getting more product with lowered production costs—quite the ideal. You can read more on the 2012 study in Holstein World or in...

The Home Energy Exhibit at the Minnesota State Fair’s Eco Experience building will feature several displays dedicated to solar and wind energy.
The Eco Experience Building will be open daily from 9am-9pm during the fair in the Progress Center on Randall Avenue, and volunteers are needed for each day!
The Minnesota Renewable Energy Society, responsible for the solar energy area, as well as Windustry, which runs the wind energy section, are looking for volunteers who are interested in chatting with attendees about clean energy and providing them with useful resources. See below for info on each opportunity!
Solar enthusiasts needed! All solar enthusiasts — expert or novice — are invited to volunteer as Solar Area Educators with the Minnesota Renewable Energy...

Please welcome Lindsay Wimmer to the Clean Energy Resource Teams! Lindsay will be working with cities, counties, schools, and other local units of government to curb energy use in their buildings through the Guaranteed Energy Savings Program (GESP).
Lindsay comes to CERTs after a year with the Minnesota Army National Guard where she provided education and outreach statewide to 60 Training and Community Centers about their buildings energy use and energy conservation strategies to integrate into building operations as part of Minnesota GreenCorps. She also worked with the MNARNG facility management office to develop a...

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 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)...

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...
