The Small Wind Guidebook helps homeowners, ranchers, and small businesses decide if wind energy will work for them by addressing the following questions:.
Can I use wind energy to power my home? Although wind turbines large enough to provide a significant portion of the electricity needed by the average U. Homeowners, ranchers, and small businesses can use wind turbines, like this Skystream 3.
Small wind electric systems can contribute to our nation's energy needs. This guide will provide you with basic information about small wind electric systems to help you decide if wind energy will work for you. Wind is created by the unequal heating of the Earth's surface by the sun. Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce clean electricity.
Today's turbines are versatile modular sources of electricity. You can start by learning how electricity is used in U. Reducing your energy consumption will significantly lower your utility bills and will reduce the size of the home-based renewable energy system you need.
To achieve maximum energy efficiency, you should take a whole-building approach. View your home as an energy system with interrelated parts, all of which work synergistically to contribute to the efficiency of the system. A small wind energy system can provide you with a practical and economical source of electricity if:. The document contains ten questions that interested parties should consider prior to installing a small wind energy system and three common mistakes to avoid.
Zoning refers to the general local regulations that allow and restrict various types of projects, whereas permitting refers to acquiring permits for a specific project within the scope of those zoning rules. The zoning and permitting processes for wind energy installations seek to address safety, aesthetics, and community interests and concerns. Practices vary dramatically across the country so becoming familiar with the local regulations, authorities, and general requirements is helpful.
In some cases, zoning and permitting expectations are consistent and straightforward. In other cases, hearings may be required and the process is uncertain. But if your project falls outside of defined limits, it must usually undergo a special review process to obtain a variance from the existing rules and regulations — a potentially expensive and time-consuming process that often involves at least one public hearing and has no guarantee of success.
Before you invest in a wind energy system, you should research potential zoning and permitting obstacles. Some jurisdictions restrict the height of the structures permitted in residential-zoned areas, although variances may be obtained.
In addition to zoning issues, your neighbors might object to a wind turbine that blocks their view, or they might be concerned about the sound it produces.
For example, a typical 2-kilowatt wind turbine operates at a noise level of approximately 55 dB 50 feet away from the hub of the turbine. The size of the wind turbine you need depends on your application. Small turbines range in size from 20 Watts to kilowatts kW. The smaller or "micro" to Watt turbines are used in applications such as charging batteries for recreational vehicles and sailboats. One- to kW turbines can be used in applications such as pumping water. Wind energy has been used for centuries to pump water and grind grain.
Wind-electric pumping systems can be placed where the wind resource is the best and connected to the pump motor with an electric cable. Turbines used in residential applications can range in size from Watts to kW kW for very large loads , depending on the amount of electricity you want to generate. For residential applications, you should establish an energy budget and see whether financial incentives are available.
This information will help determine the turbine size you will need. Wind turbine manufacturers, dealers, and installers can help you size your system based on your electricity needs and the specifics of your local wind resource and micro-siting. A typical home uses approximately 10, kilowatt-hours kWh , an average of kWh per month. The manufacturer will also provide information about any maximum wind speeds at which the turbine is designed to operate safely. Along with information about your local wind resource wind speed and direction and your energy budget, this information will help you decide which size turbine will best meet your electricity needs.
Small wind turbines can be divided into two groups: horizontal axis and vertical axis. These turbines typically have two or three blades that are usually made of a composite material such as fiberglass. Vertical-axis wind turbines consist of two types: Savonius and Darrieus. A Savonius turbine can be recognized by its "S" shaped design when viewed from above. Darrieus turbines look like an eggbeater and have vertical blades that rotate into and out of the wind.
The amount of power a horizontal-axis turbine will produce is determined by the diameter of its rotor. The diameter of the rotor defines its "swept area," or the quantity of wind intercepted by the turbine.
The turbine's frame is the structure onto which the rotor, generator, and tail are attached. The tail keeps the turbine facing into the wind. Because wind speeds increase with height, the turbine is mounted on a tower. The tower also raises the turbine above the air turbulence that can exist close to the ground because of obstructions such as hills, buildings, and trees.
A general rule of thumb is to install a wind turbine on a tower with the bottom of the rotor blades at least 30 feet 9 meters above any obstacle that is within feet 90 meters of the tower. There are two types of towers: self-supporting free-standing and guyed. Guyed towers, which are the least expensive, can consist of lattice sections, pipe, or tubing depending on the design ; supporting guy wires; and the foundation. They are easier to install than self-supporting towers.
However, because the guy radius must be one-half to three-quarters of the tower height, guyed towers require space to accommodate them. Tilt-down towers can also be lowered to the ground during hurricanes and other hazardous weather conditions.
Aluminum towers are prone to cracking and should be avoided. Costs in addition to the turbine and the tower are the balance of system, including parts and labor, which will depend on your application. For example, the parts required for a water-pumping system will be different from the parts required for a residential, grid-connected application.
The balance of system equipment required will also depend on whether the system is grid-connected, stand-alone, or part of a hybrid system. For a residential grid-connected application, the balance of system parts may include a controller, storage batteries, a power conditioning unit inverter , wiring, foundation, and installation. Many wind turbine controllers, inverters, or other electrical devices may be stamped by a recognized testing agency, such as Underwriters Laboratories or Intertek.
Stand-alone systems systems not connected to the utility grid require batteries to store excess power generated for use when the wind is calm. They also need a charge controller to keep the batteries from overcharging. Automotive batteries are shallow-cycle batteries and should not be used in renewable energy systems because of their short life in deep-cycling operations.
Small wind turbines generate direct current DC electricity. In very small systems, DC appliances operate directly off the batteries. If you want to use standard appliances that use conventional household alternating current AC , you must install an inverter to convert DC electricity from the batteries to AC.
Although the inverter slightly lowers the overall efficiency of the system, it allows the home to be wired for AC, a definite plus with lenders, electrical code officials, and future homebuyers. For safety, batteries should be isolated from living areas and electronics because they contain corrosive and explosive substances.
Lead-acid batteries also require protection from temperature extremes. In grid-connected systems, the only additional equipment required is a power conditioning unit inverter that makes the turbine output electrically compatible with the utility grid.
Batteries are usually not required. Installation costs vary greatly depending on local zoning, permitting, and utility interconnection costs. Although wind energy systems involve a significant initial investment, they can be competitive with conventional energy sources when you account for a lifetime of reduced or avoided utility costs.
The length of the payback period—the time before the savings resulting from your system equal the cost of the system—depends on the system you choose, the wind resource on your site, electricity costs in your area, and how you use your wind system.
Compare prices when shopping for a wind system as you would any major purchase by reviewing the product literature from several manufacturers. To justify your investment in a small wind turbine, you will want assurances that your turbine model has been evaluated for safety, performance, and functionality.
Research small wind turbine companies to be sure they offer certified turbines and that parts and service will be available when you need them. Ask for references from past customers with installations similar to the one you are considering. Ask the system owners about performance, reliability, and maintenance and repair requirements, and whether the system is meeting their expectations. Also, find out how long the warranty lasts and what it includes.
You must decide whether you will perform the installation and maintenance work on your small wind turbine or whether you will hire an experienced small wind installer. This decision will affect your system's cost.
Many people elect to install their own turbines. Before attempting to install your wind turbine, ask yourself the following questions:. If you answered no to any of the above questions, you should probably hire a system integrator or installer. A credible installer may be able to provide many services such as permitting, obtaining interconnection approval, etc.
Find out if the installer is a licensed electrician. Ask for references and check them. You may also want to check with the Better Business Bureau. Turbine and tower manufacturers should provide their own operations and maintenance plan; however, turbine owners should be aware that all rotating equipment will require some maintenance. Many turbines require periodic lubrication, oil changes, and replacement of wear surfaces such as brake pads. The machines should be checked for corrosion and the guy wires for proper tension.
In addition, you should check for and replace any worn leading edge tape on the blades, if appropriate. After 10 years, the blades or bearings may need to be replaced, but with proper installation and maintenance, the machine should last 20 years or longer. Every turbine should include an owner's manual or operations manual to provide the consumer with scheduled and unscheduled maintenance information as well as other unique product information.
Scheduled maintenance guidelines should be followed. If you do not have the expertise to maintain the machine, ask whether your installer provides a service and maintenance program.
Notice that the wind speed V has an exponent of 3 applied to it.
They can be tied together, like solar panels, as long as they are placed roughly 58 feet apart. Generally, home wind turbines can manage wind speeds of up to mph before they begin to break or malfunction. Please provide a valid price range. It also credited rising electricity prices and greater public awareness of wind technologies for an increase in residential sale.
