A Short History of Wind Power Today’s Wind Opportunity Our offering Questions Zephirus – Greek God of the West Wind (the Spring Wind) What is Wind? Wind is moving air. The Sun heats up some parts of the Earth more than others. Hot air rises, causing cold air to replace it. Wind is the result. It spreads heat more evenly around the world, creating the prevailing winds, as shown. This is why wind may be considered a form of solar power. Wind Market Potential in US Wind energy is harvested only where there is wind. Installation sites should (generally) have average wind speed of 11 mph or more to produce sufficient energy to justify the installation cost 10% of American households (14 million) is the estimated available residential market - in addition to commercial, and industrial markets.

History of Wind Power in America A typical Western view Over 6 million windmills are estimated to have been sold in the West before electricity became widespread. Windmills in Sears Catalog – Only $35! History of Wind Power in America Halladay Windmill from US Engine and Pump Co. America’s first commercially produced windmill, developed in 1857 by D. Halladay of CT. History of Wind Power in America Charles F. Brush Inventor of world’s first windpowered electrical generator The dynamo was connected to 408 batteries in Brush's basement. These dry cells illuminated 350 incandescent lamps, ranging from 10-50 candlepower, and operated three electric motors and two arc lights. The whole contraption produced 12 kilowatts at its peak. The windmill reportedly lasted for 20 years, until 1909. Brush's batteries lasted until 1929. c.1888 – Brush Wind Dynamo at his mansion in Cleveland, OH. 60 feet high, 56 ft diameter, 40 tons, 12kW peak power at 500 rpm History of Wind Power in America • Battery charging turbines were popular in the early 1900’s prior to the spread of rural electricity during the Depression Era. • Sears, Zenith, Montgomery Ward, Wincharger, Jacobs, were examples of small wind turbines for this market. History of Wind Power in America • As electrification expanded in the early 1900’s, the appeal of wind turbines lessened, and the windcharger market collapsed in the 1940’s and 1950’s. • America became “totally electrified” in the 1950’s and 1960’s (as well as “automobile-ized and suburb-ized”) based on the premise of unlimited cheap energy – most of which came from capital-intensive, highly centralized power sources. History of Wind Power in America • The oil crisis of the early 1970’s, the collapse of the nuclear industry in the early 1980’s, the growth of environmental concerns, new legislation and funding, plus the recent run-up in energy costs and economic recession, have renewed interest in alternative energy sources. Renewable Energy will be a major growth market for decades to come. What are small wind turbines? A device that produces electricity from the wind Typically less than 100kW rated output Most look like miniature versions of their larger cousins 2 blade, 3 blade or other Up wind, down wind and vertical axis Types of towers Dealer/Installer Overview 18 | 7/17/2015 Different Types of Wind Generators Upwind Downwind Wind Direction Different Types of Wind Generators Vertical Axis Horizontal Axis Drag Savonius Crossflow American water pump Sailwing Lift Darrieus Giromill Traditional Propeller Future of Wind Power in America • IEC Definition of a Small Wind Turbine: A wind turbine with a swept area of less than 200m2 = equivalent to a horizontal axis turbine of approx. 16m diameter • The U.S. market for 100 kW and smaller wind turbines grew 78% in 2008 • The American Wind Energy Association projects 30-fold growth within as little as five years Towers • Mono poles Typically inside climb Most preference for urban location Typically most eye appealing • Lattice towers Typically most rigid 4 legged or 3 legged • Guyed towers Least cost High wind load Dealer/Installer Overview | 22 7/17/2015 Controllers UL listed or PE approved Dealer/Installer Overview | 23 7/17/2015 Opportunities in wind energy Dealer/Installer Overview | 24 7/17/2015 Consumers – owners • Farmers • Commercial/Industrial • Residences • Schools • Municipalities • Utilities Dealer/Installer Overview | 25 7/17/2015 Electrical Contractors • Opportunity to diversify • Opportunity to sell • Opportunity for on-going maintenance • Service • Expanded product offering – “one stop shop” • Already have the relationship Dealer/Installer Overview | 26 7/17/2015 Wholesale distributors • Diversity • Partnerships • Parts and maintenance • Familiar role with part stocking and problem solving • Sales of new equipment Dealer/Installer Overview | 27 7/17/2015 Electric Utilities Great opportunity to hit the sweet spot!
