From two presentations by Michael Vickerman at the 2009 Wisconsin Renewable Energy Summit, Milwaukee:
Getting Serious About Solar Hot Water
Value Proposition to System Owner
+ Less expensive (on a life-cycle basis)
+ Predictable return
+ Negligible risk
Value Proposition to Society
+ Emission-free
+ Non-depleting
+ Indigenous
+ Highly secure
SHW Potential in Wisconsin
+ Can offset between 2.6% to 4.1% of NG use
+ Avoiding 150 million therms/year
+ Saving $150 million annually (2006 prices)
+ Offsetting 820,000 metric ton of CO2
Economic Development Impacts of Renewable Energy
Economies of scale are achieved by shrinking the labor contribution relative to output, which explains why utility-scale energy is less expensive than do-it-yourself energy.
Distributing renewable energy through customer-sited systems increases job-hours per energy unit produced as well as promoting entrepreneurship and small business development. . . .
From Small Systems – Big Results in Germany:
+ Utilities are required to accept power from customer-sited RE systems through fixed, long-term buyback rates
+ 15% of Germany’s electricity now generated from renewables
+ In 2007 $14 billion invested in RE
+ Germany has half the world’s PV capacity
+ Payoff: 300,000 people employed in the RE sector.
And in Wisconsin:
+ 338 Focus on Energy-funded RE systems installed
+ 40% increase over 2007
+ $3.5MM incentives obligated
+ Full-service installers — 35 PV; 24 biogas; 64 SHW; 21 wind; 15 biomass.
From another presentation at the Wisconsin Wind Energy Supply Chain Workshop:
Windpower in Wisconsin: Outlook for 2009 and Beyond
Why Promote Windpower?
Clean = Environmental
Non-depleting = Energy Security
Fixed Price = Risk Management
Creates Wealth = Economic Development
Scalable to Utilities = Practicality
The current Renewable Energy Standard (RES) will yield an additional ~4.2 billion kWh/yr of qualifying renewable electricity by 2015, assuming no load growth.
Assuming that windpower generates 90% of that quantity, about 1,600 MW of wind capacity must come on line between 2004 and 2015 to satisfy the RES.

From Turbines and Health published by the American Wind Energy Association (AWEA):
The American Lung Association’s agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: “Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming.”
Wind energy is one such solution – a clean energy source that can provide communities with decreased greenhouse gas emissions, along with air quality improvements and corresponding human health benefits. . . .
+ The wind industry takes health concerns seriously . . .
+ Wind energy can help improve air quality . . .
+ Wind energy can help reduce global warming pollutants . . .
+ Wind plants are very quiet compared to other types of industrial facilities, such as manufacturing plants. But wind plants typically are located in rural or low-density residential areas, where turbine noise may be more obvious because background noise is lower than in urban areas. On the other hand, the turbine noise may often be masked by the noise of the wind itself – especially since turbines are located where the wind speed is higher than average and because they operate only when the wind is blowing.
+ The sounds emitted from wind turbines can be mechanical, from internal equipment such as the gearbox or yaw drive, or aerodynamic, from air moving past the rotor blades. Current turbine designs effectively reduce mechanical sound through sound proofing; therefore, the aerodynamic sound, often described as a “whooshing” sound, is what can normally be heard.
+ There is no reliable evidence that low-frequency sound from wind turbines is a problem . . .
+ Shadow flicker occurrence is easily calculated . . .
+ Shadow flicker is not harmful to persons with epilepsy. The allegation is sometimes made that shadow flicker from wind turbines can cause epileptic seizures. This is not true—shadow flicker from wind turbines occurs much more slowly than the light “strobing” associated with seizures. The strobe rates necessary to cause seizures in people with photosensitive epilepsy are 3 to 5 flashes per second and large wind turbine blades cannot rotate this quickly.

Wisconsin Wind Energy Supply Chain Seminar
Appleton, Wisconsin
March 31, 2009
Wisconsin Wind Energy Supply Chain Seminar will focus on wind turbine manufacturing challenges and opportunities in the state of Wisconsin. Over 8,000 components and parts are used in the construction of utility-scale wind turbines, offering opportunities for a wide range of manufacturers and service providers in Wisconsin. The existing manufacturing and service industries, as well as academic and other institutions in Wisconsin makes it an ideal state to benefit from the growth of the wind energy industry.
Hear from The Honorable Jim Doyle Governor of Wisconsin
Tuesday, March 31, 1:30 PM – 2:00 PM
Governor Jim Doyle is focused on creating opportunity for all of Wisconsin’s people and is building upon current efforts to create jobs, make America energy independent, and address the global climate crisis.
