From a fact sheet pubilshed by Focus on Energy:
Pole-mounted solar electric systems offer an excellent opportunity for businesses to display a commitment to renewable energy. Also called solar flags, these systems are economical because they tend to be small. Today, solar flags are seen outside business establishments, in parking lots and in city parks. Not only do solar flags generate electricity, they also promote clean energy technology in a highly visible way.
When most people think of solar panels, they think of roof-mounted systems. However, roof-mounted systems are often hidden from view, partially shaded by trees, or not facing the best direction to capture solar energy. Solar flags can be installed in highly visible locations and positioned optimally to capture sunlight. Installing a solar flag does not involve attaching anything to your building, and the occasional maintenance requirements will not include a trip to the roof. Also, unlike roofmounted systems, pole-mounted solar flags do not need to be removed and reinstalled when the roof is replaced.
Solar electric flags can offer great economics and a relatively low cost. They are available in different sizes and prices (see Table 1). Costs tend to be significantly lower for business owners who pay federal taxes. If your electric utility offers a solar buyback rate, your solar flag can pay for itself in less than ten years. What’s more, some utilities offer additional incentives to nonprofit organizations and government agencies.

From an article by Tom Content in the Milwaukee Journal Sentinel:
Ixonia – Zero is the latest buzzword for green building – as in houses that generate as much power as they use. Although going green often is seen as more expensive than conventional construction, some homebuilders are trying to change that. Instead of granite countertops and fancy playrooms, the homes have solar panels and heat pumps.
Tom and Verona Chambers of Black River Falls recently moved into a new home that includes solar panels on the roof, a ground source heat pump and a gizmo that reuses shower water to preheat water coming in from the city.
“We don’t have a gas line into the house – zero cost for gas. We have an electric line, but the goal is to produce as much as we use so we don’t have any electric bill,” Tom Chambers said.
There’s a higher upfront cost to having a completely green home. But federal tax credits and grants from the energy conservation group Focus on Energy and a local utility, WPPI Energy, helped bring down that extra cost.
“The other side of the coin is the ongoing utility costs that we will not have,” Chambers said.
Closer to Milwaukee, developer Mark Neumann wants to take zero-energy construction a step further.
After touring a green home last summer, Neumann and his son began designing a house that would go beyond zero-energy.
The result: a home now under construction in Ixonia that will produce all the energy that would be consumed in the house – as well as the electricity that a plug-in hybrid vehicle would need for a daily commute.

From an editorial in the Milwaukee Journal Sentinel:
No one should consider the radar problems posed by a Dodge County wind farm as a reason to slow the push for more wind-generated power in Wisconsin. While the issue needs to be explored, it isn’t significant enough to warrant slowing down the move toward more renewable energy.
The state needs more wind farms and other renewable sources if it’s going to move away from fossil fuels that help contribute to pollution and climate change.
According to the National Weather Service, the wind farm’s turbines are sending false storm signals to the government’s weather radar system. Weather service officials say they see no significant public safety threat, although they say the wind farm could confuse some storm watchers.
Meteorologist Marc Kavinsky told the Journal Sentinel’s Scott Williams that the approaching summer storm season will be the federal agency’s first opportunity to gauge the wind farm’s full impact.
Just outside the Dodge County community of Iron Ridge, the wind farm includes 36 turbines that began operating over the past few months, generating electricity for several surrounding communities.
A spokesman for the owner of the wind farm, Babcock and Brown Ltd., said the company has not encountered a similar problem with any of its other 24 wind farms operating throughout the country.

From an article by Meredith Thorn in the Stevens Point Journal:
It looks like a large black box clinging to the side of the new airport hangar, but it is really a one-of-a-kind energy savings tool for the Stevens Point Municipal Airport.
The wall collects the sun’s heat and fills with warmth. The warmed air then is pulled into the hangar, said Joe Wheeler, the airport manager.
Because it’s so new, the actual energy savings have yet to be calculated. But, Wheeler said, in two months, savings have been “pretty significant.”
“Utilities on the hangar (are) going to be very cheap,” Wheeler said.
The hangar will be a “community” hangar, meaning pilots can rent an unspecified hangar space in the building, and airport employees will take care of the rest, Wheeler said. Rental rates have yet to be determined for the hangar, which can fit eight single-engine planes.
Wheeler didn’t say how much the project cost, but said the wall was completed by Sunny Solutions, a Berlin, Wis.-based company.
It’s the first solar transpired wall in Wisconsin, said Stevens Point Mayor Andrew Halverson.
“We want to be a leader in sustainability issues,” he said, and the project was a way for the city to put “its money where its mouth is” on energy-saving and environmentally friendly projects.

From a post on Tom Content’s blog on JSOnline:
A bill to create uniform siting standards for wind power projects across Wisconsin is being introduced again after stalling a year ago.
Sen. Jeff Plale (D-South Milwaukee), chair of the Senate Energy and Utilities Committee, is circulating a bill that would call on the state Public Service Commission to develop uniform siting standards for wind power projects across the state.
Wisconsin state law requires large wind power proposals to be reviewed and approved by the state Public Service Commission, but leaves smaller projects in the hands of local governments.
Several counties and communities around the state have enacted ordinances that amount to bans on wind power, however. His bill would call on the state Public Service Commission to engage with counties, towns, utilities and others on developing a comprehensive set of standards that wind projects would have to follow.
“We made it a priority in this state to harness wind, and if we’re going to do that we can’t have one township or one village dictating energy policy for the rest of the state,” Plale said. “We have to have a comprehensive look at it. That’s what we’re getting at.”
Plale said the bill is expected to fare better this year because it is being handled earlier in the legislative session and there is less confusion about what the bill would do.

From an article by Joe Knight in the Eau Claire Leader-Telegram:
A national expert on sustainability who has met with Eau Claire city officials, UW-Eau Claire staff and Luther Midelfort staff says Eau Claire is taking the first steps toward being more efficient and environmentally friendly.
“I think there’s a real interest and excitement in Eau Claire … the hospital has been doing some great things, and the city and university,” Gips said.
Gips, president of Minnesota-based Sustainability Associates, will speak Monday at UW-Eau Claire to kick off a series of events the university and community groups are planning to commemorate Earth Day (April 22), which they have expanded to Earth Month.
“I’m going to share about this very exciting movement going on around the country, actually around the world, but especially in Wisconsin,” he said.
Wisconsin has more cities designated as “eco-municipalities”, which have agreed to use sustainable principals, he said. Washburn and Ashland were the first two. Madison, La Crosse, Menomonie, Dunn County and the city of Eau Claire are among more than 20 communities in the state that are either “eco-municipalities” already or are taking steps in that direction.
Gips advocates what he calls the “natural-step framework” for making companies, cities – even churches – more efficient and sustainable. The framework was developed in Sweden. IKEA was the first business to use it, but now many U.S. companies have adopted it, he said. The U.S. Army and Navy are also using the “natural-step framework.”
Over the past year, various Eau Claire city departments have been assessing sustainability, said city manager Mike Huggins.
“Specifically, they’re looking at energy, reducing waste streams and looking at the concept of sustainability through the ‘natural step’ process,” Huggins said.

From a news release issued by Venture Electronics:
Venture recently finished the installation of a 250 kW solar array at the Johnson Controls Headquarters in Glendale, WI. This massive solar array is currently the largest ground mounted solar field in Wisconsin. The largest roof mount array at the GE Waukesha facility also was installed by Venture Electric.
“The Johnson Controls job was quite a project. It took a total team effort to get this array built on time. It proves that solar energy isn’t just for the Sun Belt,” said Venture Electric’s project manager Jim Seefeldt. Venture’s crew battled sub-zero temperatures to erect an intricate maze of piping that created the framework to support the 1452 solar panels. “Each panel had to be at exactly 30 degree for optimal collection of solar energy. It’s like a massive erector set that makes electricity,” said Electrician Foreman Marty Schultz.
A single solar panel generates approximately 33 volts DC (direct current). Each panel is combined with other panels until it reaches 480 volts DC. This DC voltage is then converted to AC (alternating current) thru an inverter. AC is used in virtually all homes in the United States. The inverter takes this converted voltage and places it back on the power grid for use by Johnson Controls and its neighbors.
The installation of these solar arrays requires a new skill set for traditional electrical contractors. “It requires electricians to abide by codes a lot of electrical contractors don’t use every day. I took it as a personal challenge (to learn the codes). It’s a lot of fun to be part of a new industry,” said Schultz
Venture Electric is excited about the growth of photovoltaic in Wisconsin. “It (PV) is the future of electrical generation and we are proud to be part of it,” said Jeffrey Robertson President of Venture Electric. “With the current administration’s commitment to “green technology” I see this as a real growth area. Photovoltaic and wind power are definitely here to stay.”

From an article by Scott Williams in the Milwaukee Journal Sentinel:
The National Weather Service has issued a new kind of warning because of a Dodge County wind farm that is disrupting the agency’s ability to monitor storms in southeastern Wisconsin.
The wind farm’s giant turbines – each as wide as a football field and as tall as a 20-story building – are sending false storm signals to the government’s weather radar system.
Weather service officials say they see no significant public safety threat, although they say the wind farm has caused radar interference and could confuse some storm watchers.
Meteorologist Marc Kavinsky said the approaching summer storm season will be the federal agency’s first opportunity to gauge the wind farm’s full impact.
“It’ll be interesting,” he said. “I’m hoping the effects will be minimal.”
Located just outside the Dodge County community of Iron Ridge, the wind farm includes 36 turbines that began operating over the past few months, generating electricity for several surrounding communities. . . .
Weather service officials said they began to notice the problem almost immediately after the Dodge County wind farm began operating.
According to a report on the agency’s Web site, the spinning wind turbines have presented “persistent interference” that mimics storm systems and could “negatively impact warning effectiveness” when real storms move into the area.
Rusty Kapela, the agency’s warning coordinator meteorologist, said officials have tried to adjust the radar system to block out the wind farm readings.
But because it affects such a small geographic area and is easily recognized by the weather service’s trained experts, Kapela said, the situation is not a significant problem. It was posted on the Web site only as an informational report for the general public, he said.
“It’s just interesting science stuff,” he said. “In the grand scheme of things, it’s just a minor blip.”
