In modern society, the problem of electricity supply is ripe. The economic crisis forces us to think about such a pressing issue as a safe and affordable source of energy. As energy prices rise, engineers are trying to create reliable alternatives for generators that generate electricity. As an alternative source of energy, scientists have proposed using the power of the wind. The most successful example of such a device is a wind generator, which can be installed in a country house, in the country
Wind farms have different plant capacities, which depend on the design model.
The advantages of using wind turbines include the absence of noise, taking care of fuel, refueling, which is inherent in gas generators. For several years of using wind energy, you will cover the initial cost of the cost of a wind generator, and then you will save money and get energy.
Autonomous power supply for a private house
Having made a choice in favor of a wind turbine, determine what result you expect, how much energy you want to receive. If your family consists of 3 - 4 people, and you want to fully meet household needs for electricity, then purchase a wind turbine with a capacity of at least 10 kW. This energy is enough for the smooth operation of a TV, refrigerator, computer and many other electrical appliances, lighting.
Based on the experience of wind turbine owners, it is beneficial to install the system from small wind turbines. Such a system accumulates wind energy for a common battery. When the need arises to increase the power of the station, new designs of wind generators are additionally installed.
In order not to depend at all on weather conditions and to ensure a stable power supply of the country house, secure yourself with an autonomous energy complex, which includes not only a wind farm, but also a backup source. Diesel generators, gas generators, solar batteries can act as such an energy source. When the wind strength is sufficient, the diesel generator does not work. If there is not enough wind power, then the backup power supply is automatically started.
Scope of use and benefits from the use of a wind turbine
Wind generators, depending on their capacity, can serve one house or several buildings. For the sake of economy, you can use the electricity from the generator and from the general power grid. When there is no centralized power supply in the garden area, and the cost of connecting power lines is high, then the purchase of a wind farm is especially appropriate. Wind turbines are also installed on objects that, for a number of other reasons, cannot be connected to power grids. When thinking about such a device, take into account the wind speed of your area, it should be at least 4 m / s.
Types of wind power plants
At the moment, two types of wind power plants have been created:
- a station with a horizontal axis - a propeller;
- a station with a vertical axis of rotation. In such stations, the generator is located under the mast, there is no need to orient the blades to the wind, but their performance requires a strong air flow and an external source to start.
Wind power plant design
The design of horizontal axis wind farms is more common and has almost the same structure, regardless of power. The basis of the windmill is a metal mast, it can be of several types: guyed, telescopic, monolithic. At the top of the mast there is a container with a generator and a gearbox with a shank with blades. The blades catch the wind flow, rotate and, accordingly, turn the rotor of the generator, which generates current. The resulting current goes to storage batteries, which supply the object with electricity even during calm periods and serve as conductors of energy. Every car owner knows this principle, because the car has a generator with a similar operating principle.
When installing wind generators, safety requirements must be observed. Usually, wind turbines are located at a distance from residential buildings, this is done to avoid destruction if the structure falls during a hurricane. However, now small and low-power wind turbines are being produced, which are mounted on the roof.
Benefits of wind farms
1. An environmentally friendly type of power plant that does not emit harmful vapors into the atmosphere.
2. No fuel purchase required. The condition for the operation of a wind farm is the presence of wind.
3. Made of modern and reliable materials that do not give in to corrosion, so the installation is durable.
4. Ease of installation.
5. A large percentage of efficiency that does not require additional costs.
6. Absence of strong vibration, noise, magnetic field during the operation of the windmill.
7. No permission is required to install a household wind generator.

Which Stove Is Suitable For A Country House
A country house is simply unthinkable without a good stove. And if it is planned to live in it throughout the year, then even more so without a stove. The stove in the country house is not only a cozy decor element, but also performs a heating function. In short, it organically combines aesthetic appeal with practical functions. Stoves of various types help to heat the country house, but most often these are still wood stoves. The most common of these are Russian and Go
Thermal Insulation Of A Wooden Floor In A Country House
Everyone knows that in cold weather, in a heated room, sometimes the feet freeze. This often depends on the construction of the floor, which has one row of planks laid on joists. Even if they are additionally covered with chipboards, linoleum, this will not prevent cold penetration into the house - insulation is needed. The most practical way to keep your home warm is with a properly made floor. Let's look at several options for floor insulation and work methods
Construction Of The Foundation Of A Country House
Construction of the foundation of a country house - it is with the construction of the foundation that the construction of any structures begins. The strength of the entire building as a whole will directly depend on the strength of the foundation. The foundation is important for both large houses and small summer cottages such as sheds and gazebos
Country House Interior
The interior of a country house - in the country you can always give full play to all your design fantasies. Indeed, in this house it is so important to create all the possibilities for a comfortable and relaxing holiday from the bustle of the city. At the dacha, people spend weekends and holidays, whole families often gather here to relax and unwind together. That is why the interior of such a house should be such that you always want to come back here, regardless of weather conditions
What To Do With Children In The Country: "Games In The Country House"
Despite the clean air, birdsong and spaciousness, it is not always possible to be outside at the dacha. The reason, most often, is one - weather conditions. In the rain and in the very heat on the street with a child, you will not particularly roam? What to do, what to do?
