Alternative energy devices for a private house. Alternative sources of electricity Alternative electricity

In an environment where energy prices are constantly rising, owners of private houses are more likely to think about alternative energy sources. Some homeowners do not have the ability to connect to the mains at all due to the high cost of installation work. Engineers, and along with them the craftsmen, drew attention to what nature itself gives to mankind and created a number of devices that can be used to renew energy resources. The video will showcase the best practices in action.

Biogas is an environmentally friendly fuel. It is used in a similar way to natural gas. The production technology is based on the vital activity of anaerobic bacteria. Waste is placed in a container, in the process of decomposition of biological materials gases are released: methane and hydrogen sulfide with an admixture of carbon dioxide.

This technology is actively used in China and on American livestock farms. To obtain biogas at home continuously, you need to have a farm or access to a free source of manure.

Biowaste generator

For the construction of such an installation, you will need a sealed container with a built-in auger for mixing, a gas outlet, a throat for loading waste and a union for unloading waste waste. The structure must be perfectly sealed. If the gas will not be taken off all the time, then it will be necessary to install a safety valve to relieve excess pressure so that the "roof" of the tank does not blow off. The procedure is as follows.

Choosing a place for arranging the container. Select the size based on the amount of waste available. For effective work, it is advisable to fill it by two-thirds. The tank can be metal or reinforced concrete. A large amount of biogas cannot be obtained from a small tank. 100 cubic meters of gas will be released from a ton of waste.
To speed up the process of bacteria working, you will need to heat the contents. It can be done in several ways: place a coil connected to the heating system under the tank or install heating elements.
Anaerobic microorganisms are in the raw material itself, at a certain temperature they become active. An automatic device in water heating boilers will turn on the heating when a new batch arrives and turn it off when the waste warms up to the set temperature.
The resulting gas can be converted into electricity through a gas powered electric generator.

Advice. The waste is used as compost fertilizer for garden beds.

Energy from the wind

Our ancestors have long learned to use wind energy for their needs. In principle, the design has remained almost unchanged since then. Only the millstones were replaced by the generator drive, which converts the energy of the rotating blades into electricity.

To make a generator, you will need the following parts:

generator. Some use a washing machine motor, slightly transforming the rotor;
multiplier;
battery and its charge controller;
voltage transformer.

Wind generator

There are many schemes for homemade wind turbines. All of them are completed according to the same principle.

The frame is assembled.
The swivel unit is installed. Blades and a generator are mounted behind it.
Mount a side shovel with a spring tie.
The generator with the propeller is mounted on the frame, then it is installed on the frame.
Connect and connect to the swivel assembly.
Install a current collector. Connect it to the generator. The wires lead to the battery.

Advice. The number of blades will depend on the diameter of the propeller, as well as the amount of electricity generated.

Heat pump

To obtain energy from the depths of the earth, it will be necessary to build a rather complex device that will allow obtaining alternative energy from groundwater, the soil itself or from the air. Most often, such devices are used to heat rooms. In fact, the unit is a large refrigerating chamber, which, when the environment cools, converts energy and gives it off in the form of heat with a high potential. System components:

Outer and inner circuit with freon.
Evaporator.
Compressor.
Capacitor.

Heat pump operation diagram

The collector can be installed vertically if the area of the site does not allow installation of a horizontal one. Several deep wells are drilled and the contour is lowered into them. It is placed horizontally in the ground to a depth of one and a half meters. If the house is located on the shore of a reservoir, the heat exchanger is laid in water.
The compressor can be taken from the air conditioner. The condenser is made from a 120 l tank. A copper coil is inserted into the tank, freon will circulate through it, and the water from the heating system will begin to warm up.

The evaporator is made from a plastic barrel with a volume of more than 130 liters. Another coil is inserted into this tank, its combination with the previous one will be carried out through the compressor. The evaporator pipe is made from a sewer pipe cut. The flow of water from the reservoir is regulated by means of a branch pipe.

The evaporator is lowered into the reservoir. Water, flowing around it, induces the evaporation of freon. The gas rises into the condenser and gives off heat to the water that surrounds the coil. The coolant circulates in the heating system, heating the room.

Advice. The water temperature of the reservoir does not matter, only its constant availability is important.

Energy from the sun into electricity

Solar panels were first made for spacecraft. The device is based on the ability of photons to create an electric current. There are a lot of variations in the design of solar panels and they are being improved every year. You can make a solar battery yourself in two ways:

Method number 1. Buy ready-made photocells, assemble a chain from them and cover the structure with transparent material. You need to work very carefully, all elements are very fragile. Each photocell is labeled in volt-amperes. It will not be difficult to calculate the required number of cells to collect the battery of the required power. The sequence of work is as follows:

for the manufacture of the case, you will need a sheet of plywood. Wooden slats are nailed along the perimeter;
holes are drilled in the plywood sheet for ventilation;
a fiberboard sheet with a welded circuit of photocells is placed inside;
performance is checked;
plexiglass is screwed onto the slats.

Solar panels

Method number 2 requires knowledge of electrical engineering. The electrical circuit is assembled from D223B diodes. They are soldered in rows sequentially. Placed in a case covered with transparent material.

Photocells are of two types:

Monocrystalline plates have an efficiency of 13% and will last a quarter of a century. They work flawlessly only in sunny weather.
Polycrystalline ones have a lower efficiency, their service life is only 10 years, but the power does not decrease when it is cloudy. Panel with an area of 10 sq. m. is capable of producing 1 kW of energy. When placing on the roof, the total weight of the structure should be taken into account.

Finished batteries are placed on the sunniest side. The panel must be equipped with the ability to adjust the inclination of the angle in relation to the Sun. The vertical position is set during snowfalls so that the battery does not fail.

The solar panel can be used with or without a battery. During the day, consume the energy of the solar battery, and at night - the battery. Or use solar energy during the day, and at night - from the central power supply network.

Homemade hydroelectric power plant

If there is a stream or reservoir with a dam on the site, a self-made hydroelectric power station will become an additional source of alternative electricity. The device is based on a water wheel, and the power will depend on the speed of the water flow. Materials for the manufacture of a generator and wheels can be taken from a car, and scraps of a corner and metal can be found in any household. In addition, you will need a piece of copper wire, plywood, polystyrene resin and neodymium magnets.

A wheel is made from 11 inch disks. Blades are made of a steel pipe (we cut the pipe lengthwise into 4 parts). It will take 16 blades. The discs are bolted together with a 10 "gap between them. The blades are welded by welding.
A nozzle is made to fit the width of the wheel. It is made from scrap metal, bending to size and connected by welding. The nozzle is adjusted in height. This will adjust the water flow.
Axle is welded.
The wheel is mounted on the axle.
The winding is made, the coils are filled in with resin - the stator is ready. We collect the generator. A template is made from plywood. Install magnets.
The generator is protected from splashing water with a metal wing.
The wheel, axle and nozzle fittings are painted to protect the metal from corrosion and aesthetic pleasure.
By adjusting the nozzle, the maximum power is achieved.

Homemade devices do not require large investments and generate energy for free. If you combine several types of alternative sources, then such a step will significantly reduce energy costs. To assemble the unit, you only need skillful hands and a clear head.

The energy of the sun, wind, earth, water - everything that was once the plot of fantastic stories is becoming a familiar attribute of modern life. The limited resources of coal, oil and wood are being replaced by inexhaustible sources of alternative energy. Moreover, every year they become more and more affordable for ordinary citizens. In addition, you can make alternative energy sources for a private house with your own hands, and for this it is not at all necessary to be a brilliant physicist.

Varieties of alternative devices

The most popular and affordable devices for the production of renewable energy are:

· solar panels;

· Wind turbines;

· Heat pumps;

· Biogas plants.

The choice in favor of this or that device will depend on your financial capabilities, as well as on the amount of available resources that will need to be converted into energy. Let's consider the pros and cons of each of these devices.

Devices for converting solar energy

The conversion of solar energy into electric current is possible thanks to solar cells. These are two-layer semiconductors, the first layer of which is characterized by an excess of electrons, and the second by a disadvantage. Under the influence of the sun, electrons move from one layer to another, and then are sent to the battery, which acts as a supplier of energy to the house.

Different types of solar cells differ from each other in the materials from which solar cells are made.

Thin film silicon. This material is characterized by the highest sensitivity, which allows you to supply the house with electricity even when there is a lack of sunlight. It is resistant to high temperatures, while other varieties begin to wear out quickly at temperatures above 50 ° C. And thanks to its plasticity, panels made of this material can be easily placed even on the most uneven roofs. However, for the minimum thickness of the elements you have to pay with reduced efficiency, which will require the batteries to take up more space in the house.

Micromorphic silicon. The next generation of photovoltaic cells differs from the previous version with a higher power and at the same time a lower price, since silicon is spent on production even less. Among other advantages is the independence of the location from the cardinal points and the angle of inclination to the roof surface.

Multicrystalline plates. The most demanded type on the market. Due to the multidirectionality of silicon crystals, the wafers give a good effect both on sunny and cloudy days. Quite powerful, however, due to oxidative reactions, they differ in a short period of operation. The battery will gradually deteriorate after the 3rd year of use.

Monocrystalline plates. The most powerful view, requiring the smallest space to accommodate. Such batteries are suitable for installation in small houses in any climatic zone, as they are not affected by adverse external conditions.

Despite the fact that alternative energy sources for the home are losing in price every year, their payback will have to wait at least ten years. The cost of even the most budgetary set of solar panels starts at 50,000 rubles, and this is on panels that do not differ in durability. With minimal design skills, it is more rational to make homemade batteries.

Self-manufacturing technology for solar panels

It is much cheaper to assemble panels for your home with your own hands than to purchase them, but you still have to spend money on the photocells themselves. It is most profitable to order them in Chinese online stores, for example, Aliexpress.

Panel collection technology includes the following steps:

1. Manufacturing of the frame. As a substrate material, you can take chipboard, glass, polycarbonate. If the frame is supposed to be made of wood, it should be painted white so that the photocells heat up less and do not fail prematurely.

2. Connection of photocells into one circuit. To do this, they are connected with aluminum conductors, parallel to each other. It is possible to purchase already bonded elements, but this will come out at a higher price.

3. Sealing the battery. It can be done with epoxy or adhesive tape. In doing so, try to avoid the formation of air bubbles, as this will affect the power of the panel.

The installation of homemade products must be done on the side of the roof where there is the maximum amount of sun. It can be used with or without a battery. Or combine the two modes, referring to the battery only when there is a lack of sun.

Wind energy converters

When it comes to the most environmentally friendly alternative source of energy, a picturesque landscape of fields with harmoniously inscribed windmills immediately comes to mind. In Europe, such a picture is really not uncommon; in our country, wind turbines are only gaining popularity.

The transformation of wind energy occurs due to the rotation of the blades located on the mast. As a result, a rotor is set in motion, generating a three-phase alternating current. And in order for the energy to acquire the characteristics necessary for domestic needs, it is passed through the controller, and then through the inverter.

All wind turbines work according to the same principle, but they can differ in several ways:

1. By the number of blades, which can be from 1 to 3, or they are absent altogether, and a sail is installed instead.

2. By the composition of materials, wind turbines can be metal, sailing and made of fiberglass. The stronger the material, the more expensive the device is.

3. By step. That is, the speed of the blades can be fixed or variable. The price of the second variety is increased due to the more complex and expensive installation.

4. In the direction of rotation of the axis, wind turbines are divided into vertical and horizontal. Vertical ones do not depend on the direction and speed of the wind, but differ in less power. In addition, they are more cumbersome and more expensive. Horizontal ones are more efficient, but completely depend on weather conditions. It makes sense to install them only in open areas and away from residential buildings, since these devices make a lot of noise.

The prices of industrial wind turbines vary widely and reach several hundred thousand rubles. But there is also a free solution - to make a wind turbine yourself. On the Internet, you can find a huge number of drawings for the manufacture of such a device from a variety of materials. The blades are made of wood and fiberglass, or aluminum or plastic pipes can be used as them. The role of the mast is played by a steel pipe with a length of 5.5 m. And for a generator, an asynchronous electric motor can be converted.

Heat pumps and biogas plants

Heat pumps are less common, but in terms of efficiency they are not inferior to other devices of alternative energy sources - wind turbines or solar panels. These devices are capable of extracting energy from any natural source - water, earth, air.

The pump consists of an external and internal circuit, an evaporator, a compressor and a condenser. The outer loop is placed in an energy source, for example, it can be lowered to the bottom of a reservoir or buried in the ground. The device then sequentially undergoes heating, evaporation, vapor compression and heat release. Such devices are capable of heating a private house even in winter at low ambient temperatures, since they no longer depend on the value, but on its constancy.

Another green innovation is the biogas plant. The device runs on pet waste and is ideal for a small farm. The result of the operation of the installation will be gas, which is formed during the fermentation process. Gas can be used for space heating, and unprocessed manure residues are an excellent fertilizer.

A variety of modern alternative energy sources allows you to provide a private house with resources without harm to the environment. Their large-scale distribution is still held back only by the lack of awareness of the population and the high cost. The last problem is solvable, since devices for the production of renewable energy are not very complex in design, and they can be made at home.

The lack of developed infrastructure in remote areas often forces owners to look for sources of alternative energy for their home. Technologies do not stand still, such things are no longer something exotic and difficult to obtain. In this article, you will find out what the market offers today as a replacement for connecting to central power grids.

What are

In the environment, energy is always present in one form or another. This is the wind, the radiation of the sun, streams of water, the warmth of the earth. It remains only to use them and transform them into the one that is needed. Consider what sources of alternative energy allow you to do this.

Solar panels

The principle of operation is based on the ability of electronic devices, called photocells, to convert the energy of photons from sunlight into electrical energy. This example of alternative energy is the most common.

In batteries manufactured for private use, silicon solar cells are used. They are of two types:

Polycrystalline. They are very fragile and therefore require careful handling. They have low efficiency - no more than 15%. Average service life is 20 years. The advantage is the low price.
Monocrystalline. More reliable. The service life can be up to 50 years. Efficiency 25%. The disadvantage is the high cost.

Benefits of solar panels:

an inexhaustible source of energy for several decades;
simplicity of installation and maintenance, for work there is no need for daily human participation;
durability;
no harmful effects on the environment and humans.

Their disadvantages are the high cost of the equipment, which takes a long time to pay off, and the dependence on the intensity of sunlight. If the sky is overcast, the power of the photocells is reduced.

Wind turbines

They are a combination of a wind turbine with blades installed on a special mast and an electric generator. When the air flows through this installation, the blades begin to rotate under their influence and set in motion the inner shaft connected to the gearbox.

This design allows the initial rotation speed to be increased. The gearbox is connected to a generator, which generates an electric current when the rotor rotates. Its surplus accumulates in the installed batteries.

Depending on the location of the axis of rotation, wind generators are divided into horizontal and vertical. The first type is more popular. Many models are equipped with an automatic turn in the direction of the wind, which significantly increases the efficiency of the unit.

The advantages of these devices are in many ways similar to solar panels. Efficiency can range from 25% to 47%, depending on the specific model and weather conditions.

The operation of the wind generator does not depend on the time of day. All you need is wind, and the stronger it is, the better. The cost of the equipment is relatively low, but the installation costs can be much higher.

The main disadvantages are noise during operation and low-frequency infrasound, which negatively affects health. For this reason, install the mast with the device as far as possible from the home.

Biogas plants

They use various waste products for work, for example, from domestic or farm animals and birds. In a sealed container, they are treated with anaerobic bacteria, which in turn release biogas.

For the process to go faster, the waste must be mixed periodically, for which a manual or mechanical stirrer is used.

The biogas enters a special storage facility, called a gas holder, where it is dried. Further, it is used as ordinary natural gas. Fertilizer can be made from the waste remaining after processing.

Modern technologies for generating energy using biogas plants make it possible to do this without performing unpleasant actions. Their main advantages:

independence from weather conditions;
saving on waste disposal;
the ability to use many types of raw materials.

The disadvantages include the following:

although it is a biologically pure type of fuel, when it is burned, a small amount of harmful emissions is emitted into the atmosphere;
it is convenient to use the installation only in areas rich in the necessary raw materials;
the cost of the equipment is quite high.

Heat pumps

It would be more correct to call them an alternative heat source. Designed for the organization of heating and hot water supply at home. They consume electricity, so they must be used in combination with other types of alternative energy.

The principle of operation is based on the ability of substances such as freon to boil at low temperatures. When it turns into a gaseous state, thermal energy is released. The installation consists of an external and an internal circuit as well as a pump circuit. The outer one is buried underground or sinks to the bottom of the reservoir.

The freon circulating through it heats up under the influence of the environment, in the pump circuit under high pressure it turns into a gaseous state, as a result of which the temperature rises to 70 ° C. The internal one carries the heat carrier heated in the pump around the house.

Heat pumps are highly efficient and capable of providing hot water and heating throughout the year. At the same time, electricity costs are minimal - with a consumption of 1 kW of electricity, an average of 4 kW of heat energy is released.

What to choose

Let's see which alternative energy option is better. Solar panels are the preferred option due to their simplicity and environmental friendliness. However, they do not work at night.

Wind turbines are well suited for areas where strong winds constantly blow. They function both day and night, but if the air flow weakens, the efficiency becomes zero. The best option is a combination of the two. Then you can be almost 100% sure that you will never be left without electricity.

Opt for a biogas plant if you keep cows, pigs or chickens on the farm, or if there is a farm nearby where you can take waste for processing.

And if you need hot water and heating, add heat pumps to your home system. They are not demanding in maintenance, there is no need to buy and store fuel somewhere, as is the case, for example, with a solid fuel boiler.

In an environment where energy prices are constantly rising, owners of private houses are more likely to think about alternative energy sources. Some homeowners do not have the ability to connect to the mains at all due to the high cost of installation work. Engineers, and with them the craftsmen, drew attention to what nature itself gives to mankind and created a number of devices that can be made with your own hands to renew energy resources. The video will showcase the best practices in action.

This technology is actively used in China and on American livestock farms. To obtain biogas at home continuously, you need to have a farm or access to a free source of manure.

Biowaste generator

Choosing a place for arranging the container. Select the size based on the amount of waste available. For effective work, it is advisable to fill it by two-thirds. The tank can be metal or reinforced concrete. A large amount of biogas cannot be obtained from a small tank. 100 cubic meters of gas will be released from a ton of waste.
To speed up the process of bacteria working, you will need to heat the contents. It can be done in several ways: place a coil connected to the heating system under the tank or install heating elements.
Anaerobic microorganisms are in the raw material itself, at a certain temperature they become active. An automatic device in water heating boilers will turn on the heating when a new batch arrives and turn it off when the waste warms up to the set temperature.
The resulting gas can be converted into electricity through a gas powered electric generator.

Advice. The waste is used as compost fertilizer for garden beds.

for the manufacture of the case, you will need a sheet of plywood. Wooden slats are nailed along the perimeter;
holes are drilled in the plywood sheet for ventilation;

performance is checked;

By adjusting the nozzle, the maximum power is achieved.

Interest in alternative sources is riveted also due to environmental concerns. Natural resources currently used to produce electricity in the traditional way are gradually being depleted.

This is a three-factor decision by many homeowners.

First, not all settlements, especially those remote from regional centers, have a properly working high-voltage mains;
Secondly, even with this communication, the condition of local power grids and transformer substations often leaves much to be desired, as a result of which emergency shutdowns have become almost the norm;
Third, considerations of energy independence from monopoly state tariffs for all types of energy resources motivate owners of suburban housing to rely only on their own capabilities.

To this, it is necessary to add the maintenance of central energy supply lines, the methods of which are outdated thirty years ago, and then the decision to use alternative energy sources in a private house will become irrevocable, convincing and motivating to take concrete action.

Interest in alternative sources is riveted also due to environmental concerns. Natural resources currently used to produce electricity in the traditional way are gradually being depleted. Moreover, the intensity of the decrease in stocks is causing concern to the entire world community. At the same time, the demand for energy increases - the number of household appliances and equipment in each house requires huge resources. Already now, on average, energy costs reach 40% of the family budget.

Technological and operational advantages of alternative energy sources

Are such systems really necessary in a private house, if until now it was possible to cope with the operation of traditional, albeit fearsome in their technical condition, power lines? engineering works in private houses, including the device of alternative energy systems.

How effective and, most importantly, necessary, may be alternative energy source for home, can be judged by the description of its operational merits:

Complete energy independence from central power supply lines;
The ability to promptly eliminate emergencies and minor malfunctions;
The ability to control the functional of all structural elements of the alternative system;
No restrictions in determining the rated power;
Absence of critical drops in the consumer power supply network;
Minimization of the risks of failure of household appliances due to violation of operating parameters in the network;
Safety control when using alternative sources;
Free choice of functional equipment, taking into account budget priorities and technological parameters.

The last point is usually of greatest interest to those who decide to install an alternative source of energy for their home.

Economic benefits

The financial advantages of alternative sources are manifested, first of all, in the ability to choose an energy supply system in an affordable price range, depending on the type of fuel resources used, technical characteristics, the credibility of the manufacturer's brand and other conditions.

At the same time, the homeowner does not bear the additional costs characteristic of centralized networks, including the costs of maintaining and repairing the central highway - he buys only equipment that will provide only his house with energy.

Another financial nuance is recurring payments. If you have your own alternative source, there is no need to pay monthly utility costs, which are completely unreasonably high.
In the list of economic advantages, you need to add the ability to reduce the cost of installation work, since they are limited only to the boundaries of the house and yard.
And finally, the main advantage is the low cost of operating equipment for alternative energy supply systems at home.

As a consequence of all these priorities, there is a very quick recoupment of such energy sources. If we add here the ability to make changes to private house project, and the low cost of such work in the InnovaStroy company, the priority of alternative sources will become quite obvious.

Technical advantages

The main technical advantage is that alternative energy source for home allows you to regulate and control the performance at the discretion of the owner of the house. Another obvious "plus" is that the owner of the equipment can always turn it off as unnecessary - in the event of a long absence, for example.

Maintenance of alternative energy sources is another advantage. Scheduled technical inspections depend only on the responsibility and desire of the homeowner. And you don't have to plan the day to accommodate the visit of a team from the central power grid service. Complete energy independence with its technical capabilities, which is provided by alternative energy sources in a private house, is also independence from government services, regulatory authorities, and their not always competent actions.

Is everything so smooth?

It would seem that such a technology for supplying electricity to a private house should have long ago supplanted traditional centralized methods of supplying energy from the market. Why isn't this happening? There are several arguments that are not in favor of alternative energy. But their importance is determined on an individual basis - for some of the owners of country houses, some shortcomings are relevant and others are not at all of interest.

For large country cottages, the not too high efficiency of alternative power plants can be a problem. Naturally, local solar systems, heat pumps or geothermal plants cannot be compared with the productivity of even the oldest hydroelectric power plants, combined heat and power plants, and even more so - nuclear power plants. However, this disadvantage is often minimized by installing two or even three systems, using more capacity. The consequence of this may be another problem - for their installation, a larger area will be required, which is not possible to allocate in all house projects.

To ensure the uninterrupted supply of the number of household appliances and the heating system familiar to a modern home, a lot of power is required. Therefore, the design should provide for such sources that can produce such power. And this requires a solid investment - the more powerful the equipment, the more expensive it is.

In addition, in some cases (for example, when using wind power), the source may not guarantee the consistency of energy production. Therefore, it is necessary to equip all communication with storage devices. Usually, batteries and collectors are installed for this purpose, which entails all the same additional costs and the need to allocate more square meters in the house.

Classification of alternative energy sources

While traditional methods require burning coal in volumes measured in tons per minute, the progressive part of humanity is trying to find a way out of the predictable energy collapse in the available natural resources. Wind gusts, the energy of sea waves, the incredible power of solar radiation and other factors are gradually becoming at the service of man. ... Already now there is a classification of the sources of alternative energy and, accordingly, equipment for completing projects of private houses.

Wind energy

People managed to tame the wind 40 years ago, when the first wind turbines appeared. In today's realities, such installations are becoming not only relevant and in demand - in some countries, equipping with wind power plants has become a trend for entire regions. There are entire regions in New Zealand that consume wind power.

In our conditions, such a trend has not yet acquired signs of such relevance and is in its infancy. Nevertheless, in some private houses, wind turbines have already appeared, producing electricity even with a weak wind movement - from 2 to 6 meters per second. In regions with strong gusts of wind, it is enough to install a mast up to 15 meters high to provide affordable electricity to several houses. Where there are few such winds, higher masts are used - up to 30-45 meters with a large blade span and their number up to 30 pieces.

Energy efficiency and economic profitability of this type of alternative energy is striking. For example, just one wind turbine producing 1 MW of energy can save 90,000 tons of oil over a twenty-year period! The same device will eliminate the need to burn 30 thousand tons of coal over the same period! At the same time, the costs of installation and operation pay off much faster than with the construction of traditional energy sources.

The need to use accumulators is somewhat overshadowed by the efficiency of wind power sources. With the inconstancy and difference in wind strength, the production of electricity from this source cannot be called stable. Therefore, it is necessary to accumulate its surplus in batteries. The disadvantage of this method is that the cost of the batteries themselves takes 25-30% of the total budget for equipping this alternative energy source. In addition, with frequent use, batteries have a short lifespan.

Energy of sun

Solar alternative energy sources for a private house more productive and more progressive in comparison even with wind turbines. Solar systems consist of solar collectors that receive and distribute solar energy, as well as a battery system and a reservoir for the coolant.

There are two types of solar plants:

With flat collectors;
With vacuum manifolds.

In the middle lane, tubular vacuum collectors are more relevant. The efficiency of the solar system is almost limitless - according to scientists, about 150-300 watts of solar energy falls per 1 square meter, which is equivalent to the use of 100 cubic meters of gas or 100-120 liters of diesel fuel. system is that such alternative energy sources for a private house can work even in cloudy weather, despite the absence of the sun.

Geothermal energy

The use of energy from the bowels of the earth is another promising direction in modern energy. Energy production is carried out using special devices - heat pumps. Pumping warm underground water and cooling it, such pumps take away thermal energy from it, converting it into electrical energy.

At the same time, they are able to provide themselves with electricity to maintain functionality. The coefficient of consumption and production of electricity is 1.6 units. Therefore, the allocated energy is quite enough to provide the consumer network and for the operation of the pump itself. It is also curious that during the generation of electricity, the heating medium for the heating system can simultaneously be heated due to the heating of the rotary elements in the design of the heat pump.

Biological sources

For example, autonomous systems and entire industrial complexes have been developed for the production of biogas, operating by releasing energy from manure, vegetation waste and even wood waste. Science is discovering new opportunities for using biological resources for energy production. For example, research has recently begun on solar energy storage using conventional algae to produce biofuels from sugar beets that could power gasoline or diesel power generators. Similarly, such alternative fuels are produced from rapeseed, soybeans and corn.

Other types of alternative energy

In recent years, interest in the use of alternative energy sources has grown, as a result of which projects using space technologies have begun to be implemented - numerous satellites can accumulate and transmit energy to the ground with stable characteristics. In addition, in the coastal regions, stations are being installed that generate energy due to the movement of waves. Another area of modern energy is the generation of electricity during a thunderstorm.

Design of houses with alternative energy sources

As you can see, even now mankind has at its disposal quite real, efficient, highly productive modern sources of alternative energy for the home.

The task of designers, builders and even the developer himself is to choose the most profitable alternative system, taking into account climatic conditions, technical features of the project, the availability of one or another source. And only experienced and competent specialists from the professional staff of the InnovaStroy company can most efficiently cope with this task. After all, it's not enough just to design a house - you need to arrange it commissioning in the presence of alternative energy sources.

And the project itself must be prepared in such a way that these sources can harmoniously fit into the overall concept of the style, and fully comply with design regulations, state standardization requirements and safety considerations. You can learn a little more about the principles, classification and methods of alternative energy sources from the proposed video materials. posted below.
