Control costs. Hedge against electric rate increases.

Investing in wind energy today is not only good for the environment, but good for your bottom line. Green Energy can help you estimate your approximate project economics once we identify several factors:

Your average wind speed at hub height

To estimate the amount of electricity produced by the Wind Sphere™, please use the Wind Sphere™ Performance Curve, which shows electric output per year at different average wind speeds. For example, at an average wind speed of 7 meters per second (about 15 miles per hour), the Wind Sphere™ will generate about 70,000 kWh/yr of electricity. There are many factors that go into calculating the performance curve and represents power generation under assumed average conditions and parameters. The actual power generation may vary from the average based on specific location. Some of the factors considered in estimating power generation are:

  • Wind Speed Profile
  • Air Density - Humid air is heavier and will generate more power than dry air at same wind speed
  • Turbulence - Even at similar geographical location, turbulence can vary depending on interference by near-by structures and topography of the land

The Wind Sphere™ Performance Curve may be used for preliminary economic estimates, but getting a more definitive estimate will require a location focused study to understand the various factors for that location, including wind speed profile. Green Energy Technologies offers a comprehensive Wind Turbine Feasibility Study to evaluate the key issues and research the most important questions, such as your average wind speed at hub height.

Your electric rate (located on your electric bill)

The higher your current and future kWh rate, the faster the payback.

Your rebates and incentives in your state

The DSIRE (Database of State Incentives for Renewable Energy) database seeks to be a complete source of information on

existing incentives available for residential and commercial users. Information includes:

  • State and utility rebate programs,
  • State and utility grant programs,
  • State and utility loan programs,
  • Corporate, personal, property and sales tax incentives, and
  • Contact information

Federal Incentives in the United States:

Federal Tax Credit (IRS Form 3468)

The American Recovery and Reinvestment Act of 20092012 allows owners of small wind systems with 100 kilowatts (kW) of capacity and less receive an uncapped investment wind energy tax credit for 30% of the total installed cost of the system.

Federal Accelerated Depreciation (IRS Form 4562)

  • Modified Accelerated Cost Recovery System
  • Five-year federal depreciation schedule
  • Rapid depreciation deductions on federal tax return
