From a fact sheet published by Focus on Energy:
Rising energy costs and concern for energy security and the environment are driving forces in a growing trend to incorporate renewable energy technology into residential housing. Focus on Energy and the Wisconsin ENERGY STAR® Homes Program recognize this as an opportunity for builders. The following checklist of building details is a first step to promote and market the construction of new homes that are built “ready” for future renewable energy installations.
PLANNING AHEAD IS THE RIGHT THING TO DO
To maximize the potential benefit of any future solar renewable energy system, the following should be considered when planning and building a home.
1. Reduce loads
Reduce or minimize energy loads where possible through the home’s heating, cooling, water heating and electrical systems. At a minimum the home should satisfy the Wisconsin ENERGY STAR Homes Program building performance standards and, where possible, incorporate ENERGY STAR qualified lighting, appliances and HVAC systems.
2. Maximize solar access
To maximize solar access, face the roof surface and pitch within 30 degrees of due south. The roof should be unobstructed from both the winter and summer sun and have a slope of between 30 degrees and 60 degrees. For more information on solar access, see the Passive Solar Design fact sheet or contact the Focus on Energy Renewable Energy Program at 800.762.7077 for solar site assessment information.
3. Follow zoning laws and applicable codes
Wisconsin State law does not allow zoning or covenants that restrict the use of a solar energy system except for reasons of health and safety. Also investigate applicable Uniform Dwelling Code and the National Electric Code as they pertain to any pre-installation requirements.

Sheboygan Press, April 17, 2009
Wisconsin should move ahead with uniform rules and regulations for siting power-generating wind turbines that could be applied statewide.
State Sen. Jeff Plale of South Milwaukee is circulating a bill to that effect in hopes of getting bipartisan support before it is introduced in the Legislature. A similar plan was proposed late in the last legislative session and was wisely shelved because there wasn’t enough time to fully explore the idea and hold public hearings.
Since this measure will take away some local control that planning and zoning rules would cover, input from local government officials, as well as the public, is critical to coming up with a workable plan.
Current state law gives the Public Service Commission the responsibility for review and approval of large wind power proposals, but smaller projects are left for local governments to decide.
Wind power is not a passing fad. It has to be a part of the solution to weaning the U.S. from fossil fuels. Until the recession hit, wind power generation was among the fastest growing industries in the nation. And, Wisconsin has chosen to be a leader, not a follower in the use of renewable sources of energy. By 2015, the goal is to have 20 percent of the electricity produced in the state come from sources other than coal- or gas-fired power plants.
It would still be best for wind turbine siting decisions to remain solely with local governments.
Neighboring Fond du Lac County is an example where it can work. Leaders in several towns have done a good job of balancing the concerns of neighboring residents with the need for renewable sources of energy in developing regulations on setbacks and noise.
But it is quite apparent that the desire to come up with reasonable rules is not universal. Some towns have written siting rules in such a way to ban wind turbine projects entirely.
There is time to conduct hearings and gather information, and a uniform set of rules on wind turbines will help Wisconsin reach a cleaner energy future sooner, rather than later.

From a news release issued by Alliant Energy:
MADISON, WI – April 17, 2009 – In the middle of 2008, Reedsburg Hardwoods decided it wanted to reduce its energy cost by taking advantage of a plentiful by-product of its own manufacturing process: wood waste. At the time, the company was using two natural gas-fired boilers and one wood waste boiler to process steam for its kilns, steamers and dryers. While the lumber mill was already powering about two-thirds of its processing operation with the wood waste boiler, it had more wood waste available to do more and wanted to effectively eliminate the use of natural gas for its wood processing energy demands.
“We really saw a great opportunity for our company to move toward completely using a renewable resource to power our lumber mill process,” said Doug Hilber, Reedsburg Hardwoods Facility Manager. “With the excess wood waste we generate and had available on and off-site, it made sense to look at purchasing a larger capacity wood waste boiler that could handle processing steam for all of our lumber mill process now and into the future.”
As with any business, cash is important and paying for the new wood waste boiler and the other upgrades needed to support it, would take upfront dollars before the long-term energy-efficiency gains could be realized. That’s where Wisconsin Power and Light’s (WPL’s) Shared Savings program stepped in to assist the company.
The Shared Savings program is an initiative that assists industrial, commercial and agricultural customers with identification and implementation of energy efficiency projects – and invests the capital to finance them. The program’s low-interest financing, and ability to repay the loan using the energy savings, is attractive to many businesses.
“I met with Doug several times and we looked at what type of boiler and other equipment would be needed to improve the natural gas energy efficiency of their lumber mill process,” said Mary Eiler-Radl, Alliant Energy Strategic Account Manager. “It turned out that the purchase of a new, higher-capacity wood waste boiler and other related equipment could accomplish that goal. The project was a perfect fit for our Shared Savings program and we were able to quickly pull the financing together.”

From RENEW Wisconsin’s Michael Vickerman:
The National Renewable Energy Laboratory today released its annual assessment of leading utility renewable energy subscription programs across the nation. Several programs offered by Wisconsin utilities finished in the Top 10 in four categories of performance. Deserving of kudos are We Energies, Madison Gas & Electric and two municipal utilities–River Falls and Lake Mills–served by WPPI Energy. Congratulations on a fine performance last year!
Individual program rankings are as follows:
* We Energies’ Energy for Tomorrow program came in 8th in total renewable energy sales and 10th in total number of customer participants.
* Madison Gas & Electric’s Green Power Tomorrow program posted the 4th highest customer participation rate and ranked 6th in terms of program sales as a percentage of overall retail electricity sales.
* The River Falls municipal utility posted the 9th highest customer participation rate and ranked 3rd in terms of program sales as a percentage of overall retail electricity sales.
* The Lake Mills municipal utility posted the 10th highest customer participation rate.
Though NREL does not keep track of solar capacity that were supported by renewable energy subscribers, it’s worth mentioning that from 2006 to 2008 We Energies leveraged the installation of 1 MW of customer-owned solar capacity through its Energy for Tomorrow program. Alliant and MGE also offers a 25 cent/kWh solar rate that is also supported by program subscribers.

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.
