• Schools
• Roof tops – commercial & residential
• Farms – agricultural - water pumps
• Restaurants and retail stores
• Recreational
• Off grid – battery backups
• Government and municipal
• Hybrid/electric vehicle charging

Why The Energy Ball

Small dimensions, decorative design

• Turbine is omni directional, spins no matter what direction

the wind is coming from.

• Virtually Maintenance free, No continued operating costs
• Low startup speed
• No vibration
• Noise does not exceed background noise

Installation of the Energy Ball

• On a mast

– Lengths available: 25’, 30’, 40’ or higher depending upon local code

• Flat Roof Mount
• Multiple Units clustered, roof top or

pole mount

• Façade Mount (side of building)

• Average wind speeds above were calculated using weighted averages for both

turbines over time, at 33’ above ground level.

Benefits of Wind Power

• Wind is free, clean, abundant and renewable.
• Cost effective for off grid, better alternative to running power lines several miles
• Back up power, much quieter than running a loud generator
• In direct balance/opposite of Solar Power – Wind & Solar have peak operating times

that are opposite of each other.

• Increase local and regional economic growth, green job’s.
• Reduce Peak demand from grid
• Requires less footprint
• Reduces CO2 and SO2

Growth Potential & Projections

• Small Wind for Residential is projected to

grow by 30-fold, according to AWEA. BUILDING-MOUNTED

TURBINES less than 0.002% of the US small-wind market Was from Building mounted Small Wind Turbines.

• Driving forces affecting growth in

Residential; manufacturing, rising electricity prices and

heightened public Awareness. (Seattle City Light has Projected 23% increase over the next three years).

• EV (Electric Vehicle) Charging Stations

Seattle CODE ISSUES

• Current Restrictions inhibiting small wind turbines

in Residential areas:

• Where we need to be:

Standard model ordinance allowing turbines in all residential areas Pass an ordinance that puts wind on equal footing as Solar, (i.e., HOA’s)

Permitting

Zoning/permitting. Poor or absent local permitting practices thwart an

Estimated 1/3 ore more of all potential small wind turbine installations. Unnecessary & restrictive regulations, can limit a turbine’s productivity, Discourage customers and investment, and repel local industry-related businesses from communities. Example: Flagpoles, lamp posts, and utility poles are allowed in front of schools and parking lots because they are engineered structures, just like wind turbine

• towers. They should all receive the Same equal treatment under law.
• The Seattle Building Code for Residential zones do not

currently include a specific section on wind turbines, as it does for solar power.

Progress in Seattle

• The Seattle City Council has just passed a

new ordinance to allow small wind turbines, meeting certain criteria to be placed on multi family buildings exceeding existing height limits as of December 2009.

Wind Power Environmental Benefits

• One block of wind power cuts CO2

emissions by 2,988 pounds each year.

• One block of wind power achieves 3.5

times the reduction achieved by recycling.

• Wind + Solar + Recycling = Smaller Foot
