How do wind turbines operate? And what wind turbine cost will you have to pay for if you have a system installed?
Wind turbines have huge blades which seize the wind. When it is windy, the blades rotate — an action which in turn drives the turbine to generate electricity. If you have strong winds, you will have more electricity generated.
Wind-powered generators exploit the wind’s strength and employ it to create electrical power. If a great percentage of the wind energy available in a particular place is blown over your home, building a wind-powered generator for home use is a good idea. You will be able to get enough energy to make your lighting system and all the electrical machines and gadgets you have at home work. Turbines which produce this much energy is referred to as micro-wind or small wind turbines. These will be sufficient for your household’s electric power requirements.
Wind generators, together with solar-panels utilized for power generation, are being acclaimed these days for the many advantages that they offer. Consider the following:
• Save on your electric bills. You just have to fork over the amount to purchase your generator, and it is savings time from then on. Watch your electric bill dwindle until it is completely eliminated. You have then become your own independent source of power.
• Earn for the power that you generate. This works two ways. By a system called feed-in tariffs, you will get payment for the electric power that you generate, even if this is for your own consumption. Any extra power that you generate, you can sell to your local grid.
• Help save the earth. Wind-generated electrical power is green and renewable energy. You are helping in the universal effort to save the planet by not releasing toxic chemicals into the earth.
• Save energy. There are of course days when the wind is not strong enough to generate a large amount of power. During these times, you can access the national grid for your power requirements. However, you also have the option of storing the excess power generated on certain days in batteries and tap on this power later on when the need arises.
How much do wood turbines cost?
This is difficult to say outright. There are many things that affect the cost of wind generators. Among these are the following:
• Dimensions of the wind power generator
• Form and nature of the turbine
• How the turbine will be mounted
Turbines which are pole-mounted are more expensive than building-mounted ones. The mounting process will influence the cost of the machine itself, plus the charges to have it installed. Just so you will have a general idea about the costs, a building-mounted 1kW small-scale generator will cost you about £2,000. A 2.5kW pole mounted one will have you spending about £15,000. A much larger pole mounted turbine of 6kW carries a price tag of close to £22,500.
• Cost of maintaining the efficacy of the turbine
You will have to, of course, spend so that your machine stays well-maintained. This will ensure that your turbine runs efficiently. Check-ups should be conducted every few years.
Costs will also depend on how big the turbine is. You will be spending approximately between £100 and £200 every year to have your turbine maintained at top form. If this is done conscientiously, your generator should run well for about twenty years. The inverter may have to be replaced at some point. Estimated cost for the replacement is between £1,000 and £2,000 for a big turbine.
If you intend to store excess energy, be prepared to replace the batteries every six to ten years. The expenses will depend on the form and dimensions of the turbine.
• Type of battery employed
• Site of your house or building which will use the generator
• Strength of the winds in this location
• Warranty period
• Feed-in tariffs which you can apply
All of these factors influence the general wind turbine cost.
