New Online Tools Help U.S. Deployment of Wind Energy Systems
The Department of Energy (DOE) announced two new online tools to assist state and local policymakers, consumers and stakeholders evaluate siting and policy issues to help accelerate the use of distributed wind energy systems such as wind turbines at homes and businesses. DOE’s Office of Energy Efficiency and Renewable Energy funded
development of the “Distributed Wind Site Analysis Tool” and “Distributed Wind Policy Comparison Tool” through American Recovery and Reinvestment Act grants. The tools are designed to help more people across the country install wind turbines to produce clean, renewable energy.
Distributed wind energy systems are typically installed near the point of electricity use at residences, businesses and community institutions such as schools and hospitals to help save energy, reduce energy bills and cut carbon emissions. The two online tools lower barriers to distributed wind energy deployment identified in DOE’s 2008 report, “20% Wind Energy by 2030.” The report identifies site-specific factors such as zoning and permitting costs, interconnection fees, shipping and other related costs as significant factors in the costs of distributed wind systems. Such costs can limit distributed system deployment even in wind-rich locations.
The Distributed Wind Site Analysis Tool, developed by the Cadmus Group, Inc., allows users to input location and terrain information about a potential wind system site in the United States and predict the energy output and environmental benefits of that site. The tool is designed to help potential wind energy system consumers choose the most effective site for their wind energy project. The standard version of the tool was developed in partnership with DOE’s National Renewable Energy Laboratory (NREL) and Encraft, and is free to site visitors. A version with more advanced features is available for an annual subscription fee.
The Distributed Wind Policy Comparison Tool, developed by eFormative Options, LLC, provides practical information for policymakers about potential state and local government policy options – including rebates, tax incentives, and ways of overcoming zoning and interconnection hurdles – to encourage rapid deployment of distributed wind energy systems. The tool allows sensitivity analyses to be conducted on various policy options and assumptions. These analyses model the impacts of policies and incentives and identify combinations of policies that may help guide efficient use of public and ratepayer funds. This tool was developed in collaboration with NREL, DOE’s Pacific Northwest National Laboratory, and the North Carolina Solar Center, and is free to site visitors.
DOE’s Office of Energy Efficiency and Renewable Energy invests in clean energy technologies that strengthen the economy, protect the environment, and reduce dependence on foreign oil. Learn more about DOE’s efforts to research, test, develop, and deploy innovative wind energy technologies.

Planned Solar Energy Farm Sold
Even before construction has started on a solar energy farm in Queen Creek, the planned facility has been sold for $75 million.
New Jersey-based PSEG Solar Source will buy the 19 megawatt solar energy farm and will sell electricity to Salt River Project for 20 years. PSEG bought the planned facility from its developer, Colorado-based juwi solar Inc. The plant will be maintained and operated by juwi after construction.
The town of Queen Creek has already approved the 158-acre facility, and construction is expected to begin this month. The site should begin operating in the third quarter.
This is the fourth juwi-built plant in the U.S. and the first one in Arizona. SRP has worked with several manufacturers and only does deals with known companies that have a proven track record like juwi, said Debbie Kimberly, SRP’s director of customer programs and marketing.
The construction will generate 120 jobs, said Paul Rosengren, a PSEG spokesman. The plant will be monitored remotely without having employees on site.
This is the third Valley solar facility providing energy for SRP. It also is purchasing power from a just-announced 1 megawatt facility at Arizona State University’s Polytechnic campus in Mesa. Also, it’s buying power from the 20 megawatt Copper Crossing facility in Pinal County.
The sites are idea because they’re near existing power lines, Kimberly said.
“The advantage of the East Valley for us, if you’ve been out there, is it’s just as flat as a pancake. You’ve got a lot of available land and it’s well situated in terms of distribution and transmission,” Kimberly said.
SRP provides about 9 percent of energy with sustainable resources that include solar, wind, geothermal, hydro power and various conservation measures. It has a goal of 20 percent in 2020.

Solar Panels – What They’re All About
The solar panel is the most basic element of a solar power system. It primarily functions to gather sunlight during certain periods of the day to power different devices and structures. Depending on the size, solar panels can power anything from RVs to huge plants. It is also important that you understand how the panels work and where you can apply these so that you can get the most benefits. Here are some more details and info about the material.
What are Solar Panels?
Solar energy starts with the sun. Solar panels are also known as photovoltaics and are primarily used to convert light from the sun. These are made of energy particles called photons that are changed into electricity to power various electrical loads. Light from the sun is considered as a renewable energy resource that gives clean energy. Solar panels can be used for different applications like remote power systems for cabins, remote sensing, telecommunications equipment and to produce electricity for commercial and residential panel systems.
The History
The development of the solar energy began more than a century ago. During the early days, solar power was used mainly to produce steam for drive machinery. Henri Becquerel discovered the photovoltaic effect that allowed the conversion of solar electric energy. Becquerel’s discovery triggered the invention of the first true solar cell by Charles Fritts in 1893, which was created by coating selenium sheets with a thin gold layer. The solar panel was then created afterwards.
Russel Ohl is an American inventor who used to work for Bell Laboratories. He patented the first silicon solar cell in the world in 1941. The first solar panel was produced by the same company in 1954 because of Ohl’s creation. The new solar panels were used first in space satellites. During the 1970s, more people saw the use of solar panels through the newly designed calculators that can run easily under light.
At present solar panels and full solar panel systems are used to power different applications and structures. Aside from calculators, solar panels are now used to give power to homes, commercial buildings and other huge structures.
Letting the Solar Panels Work
Solar panels can gather clean renewable energy in sunlight form that will be converted into electricity. The average home has adequate roof area to let solar panels gather enough sun to be converted into DC current or AC current. Solar panel arrays can be sized to meet big requirements. The AC current can power loads in the house and other commercial buildings. It is important to consider the part of the house, as well as the right angle of the sun so that the solar panels can gather the most light over more hours of the day for optimum results.
You can choose to build your own solar panels or just order a pre-made one online. There are also a number of stores that offer solar panels, depending on the use… Continue reading
Pros and Cons of a Solar Lease Program
The cost of solar grid-tie systems still remains costly for the home owner.
However, a solar lease program can cost you one half the cost of buying your own system. Solar leasing is an affordable way for a home owner to save almost instantly on their electrical cost. But there are some things to consider about a lease versus a completely purchased system. Below, I have laid out some pros and cons about solar leasing. Pros:
Cons:
As you can see, a solar lease needs to be carefully studied by the home owner and balanced out financially if it is a feasible option.
