Last week, the U.S. Department of Energy reported that in 2012, wind energy was the fastest-growing power-generation sector for the first time in our nation’s history. The sector accounted for 43 percent of all new U.S. electric generation capacity and $25 billion in new investment.
Check out the infographic below for more statistics from the report:
You can also watch how wind energy has grown across the U.S. with the Department of Energy’s new interactive map. See where and when wind farms were assembled over the past four decades (snapshot shown above right).
Minnesota is no stranger to advancing wind energy projects. Xcel Energy has proposed a $1.1 million grant to help install 50 10-kilowatt turbines...

Halogen, CFLs, LEDs, Watts, Lumens—what’s the difference? What’s best? We’ve got you covered! Lighting a typical Minnesota home accounts for about 10 percent of the energy needed to power one’s home. One of the best ways to reduce your electricity bill is to replace traditional incandescent light bulbs with ENERGY STAR labeled compact fluorescent light bulbs (CFLs) or light emitting diode bulbs (LEDs).
How can I save money on my lighting bill?
Halogen bulbs are one lighting option. They last about three times longer and use 10 percent less energy than a standard incandescent bulb with the same light output. But they rank well below CFLs and LEDs in efficiency and longevity.
CFLs use about one-...

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...

The West Central Research and Outreach Center has recently turned what was just a dream in 2002 into a reality. The project began with a vision of capturing wind energy and using it in an innovative way; the end product was the completion of the Renewable Hydrogen and Ammonia Pilot Plant located in Morris, Minnesota.
The plant’s function is to ultimately create NH3 (ammonia). How does it work? Nitrogen and hydrogen are created using wind, air, and water. Nitrogen is pulled out of the air by pressurizing air to vent out the oxygen, carbon dioxide, and other chemicals to leave behind the nitrogen molecules. A current of electricity produced by the wind turbine is put into water, splitting the hydrogen and oxygen. The oxygen is vented off to leave behind pure hydrogen. After a process of mixing the nitrogen and hydrogen and then heating...

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:...
