Alternative energy sources

 

Alternative energy sourcesWithout energy, human life is unthinkable. We are all used to using fossil fuels as energy sources - coal, gas, oil. However, their reserves in nature are known to be limited. And sooner or later the day will come when they will run out. To the question "what to do in anticipation of the energy crisis?" the answer has long been found: we must look for other sources of energy - alternative, non-traditional, renewable.

What are the main alternative energy sources?


Solar power

All kinds of solar systems use solar radiation as an alternative source of energy. Radiation from the Sun can be used both for the needs of heat supply and for generating electricity (using photovoltaic cells).

The advantages of solar energy include the renewability of this energy source, noiselessness, and the absence of harmful emissions into the atmosphere when solar radiation is converted into other types of energy.

The disadvantages of solar energy are the dependence of the intensity of solar radiation on the daily and seasonal rhythm, as well as the need for large areas for the construction of solar power plants. Another serious environmental problem is the use in the manufacture of photovoltaic cells for solar systems of toxic and toxic substances, which creates the problem of their disposal.


Options for using solar energy:

How are solar panels arranged and work?

Solar shingles Tesla

Efficiency Solar Panels

Polymer Solar Panels

Solar Power For Home

Solar lights

Homemade solar panels and their industrial counterparts

Solar mendonsin motor

Nanoantennas - device, application and prospects of use


Wind power

One of the most promising sources of energy is the wind. The principle of operation of the wind generator is elementary. The strength of the wind is used to set the wind wheel in motion. This rotation is in turn transmitted to the rotor of the electric generator.

The advantage of a wind generator is, first of all, that in windy places, the wind can be considered an inexhaustible source of energy. In addition, wind generators, by producing energy, do not pollute the atmosphere with harmful emissions.

The disadvantages of devices for the production of wind energy include the inconstancy of wind power and the low power of a single wind generator. Also, wind generators are known for making a lot of noise, as a result of which they try to build them away from places of residence of people.

Geothermal energy

A huge amount of thermal energy is stored in the depths of the Earth. This is because the temperature of the Earth’s core is extremely high. In some places of the globe there is a direct exit of high-temperature magma to the Earth's surface: volcanic regions, hot springs of water or steam. The energy of these geothermal sources is proposed to be used as an alternative source by supporters of geothermal energy.

Geothermal sources are used in different ways. Some sources are used for heat supply, others - for generating electricity from thermal energy.

The advantages of geothermal energy sources include inexhaustibility and independence from the time of day and time of year.

The negative aspects include the fact that thermal waters are highly mineralized, and often also saturated with toxic compounds. This makes it impossible to discharge waste thermal water into surface water bodies. Therefore, for waste water, it is necessary to pump back into the underground aquifer. In addition, some seismologists oppose any intervention in the deeper layers of the Earth, arguing that this could trigger earthquakes.


Use of other types of alternative energy sources:

Mini and micro hydropower plants - popular designs and applications

Nanogenerators for snares of portable devices

Using the energy of gravity

Paving slabs generating electricity

Osmotic power plant: pure salt water energy

Minato's magnetic motor: is there a cornucopia of magnetic energy?

Piezogenerators are new sources of electricity. Fantasy or reality?

Home-made mini-hydroelectric power station and its industrial analogues

Fuel Cells - Alternative Power Supplies

Thermogenerators: how to “weld” electricity on a gas stove

Indigirka - a wood-burning electric generator or a new Russian stove

Electrical energy from plants - green power plants

Super Flywheels - New Energy Storage Batteries

As you can see, an alternative to traditional sources of energy exists. And this gives us hope that in the future humanity will be able to overcome the energy crisis associated with the depletion of non-renewable energy sources!

    In the modern world, a serious problem has ripened - this is abuse, oil is such natural resources, and we are apparently ready to die in order to keep everything this way, as it is cheap and easily accessible. The funny thing is that low oil prices are actually not beneficial for the long-term well-being of our economy. With high oil prices, we must focus on maintaining quality or switching to various alternative energy sources. Once prices go down and we return to the same problem, our wastefulness becomes a bad habit.
    If the crisis in the oil industry leads to another jump in prices then it is worth considering. Further tactics of such behavior will lead to global warming and a crisis in the global economy.
    Alternative sources of energy, such as solar energy, not only renewable and environmentally friendly technologies, will be able to ease our strong dependence. It is time for us to channel our energy into an innovative, creative and inventive way of thinking.
    Nowadays, all wars are fought over resources such as oil. Americans in wars lose their fathers, husbands of brothers, families lose their loved ones. Against the backdrop of today's development of science and technology, the path is open for new innovative technologies and alternative energy sources.

    The site is very good, thanks to the admin.
    At the expense of alternative energy. A few years ago, Russian scientists created a device with which you can get energy equal to production. Vladimir Putin himself was even informed of this. However...
    This is not to say that the authorities are inactive .. No one will allow the world to switch to alternative energy sources that have long been a reality. Imagine, corporations in the gas, oil and energy sectors will perish .. States will gain independence ... Oh, that will be.But until oil and gas run out, while you can buy expensive cars, dictate terms to someone until oil and gas production is possible .. no one will allow alternative technologies to enter our lives .. And even so ... people will be left without work ... they need to be taken somehow .. And there is a solution that again does not like ..

    Website FRUITFUL !!! I'm interested in the question ... Pyramids and pyramidal effect. The fact that Energosbyt writes in the slogan “We bring you Light”, I apologize, but complete LA-PU-TA! Light "comes" from the rivers by means of GES + wires and powerful L.E.P. VERY MUCH USEFUL Material! Admin website promotion and creative INSPIRATION! Site, of course, add to bookmarks.

    Wind and sun - a bright future for energy and all of Russia! Just as at the beginning of the 20th century, people did not dare to change from a horse to a car, so at the beginning of the 21st century they are very cautious in this matter. And they didn’t want to do it right - the cars at that time did not have the current strength and speed, they broke down often, they could not repair them, and there were no spare parts. So with windmills like that. But this is already in the past. Now the windmills have become like perpetual motion machines: once set, and operates for many years. This type of wind turbine 2000. At 2 kilowatts. Modern windmills, like cars, work silently, for a long time, and are rarely serviced. There is a propeller type, they have more efficiency, and they have maximum speed. There is a rotor type, they have less speed, they work absolutely silently. Modern materials and technologies have solved the problem of energy production. However, according to manufacturers, electricity produced by small windmills is more expensive than large megawatt power. But on expensive modern foreign cars, travel is also more expensive than on a bus, but they buy and drive. Because there are more opportunities, and they travel longer. With windmills, the exact same situation is repeated as with cars. But the windmill can be supplemented with solar panels, and a diesel generator to guarantee continuous operation and power supply. And now a farmhouse in several houses will be provided with its electricity for many years. And it is necessary to do this now, because the main energy is given by hydroelectric power plants, and their service life has already expired. Many structures have been operating for almost a hundred years. Many are in disrepair. Therefore, hope for chance is not necessary. And rely only on yourself and create cooperatives with neighbors to provide electricity. It is possible to decide at the level of settlements, production complexes, agricultural cooperatives. It will be cheaper than a windmill for everyone!

    There was a store from the Energeticus portal where inventors directly sell their 3dproektant creations. So I think soon you can completely stop paying for electricity.

    I have a small business in the city. I eat 20 MW per month. How many windmills, panels and diesels should I have and what will it pour out to me? The wind must constantly blow (not the breeze) and the sun does not set in the wild West. Everything is good so far to power the nightlight over the bed.

    A very interesting selection of articles. Everything is written simple and affordable. But it would be interesting to read not just a description of new ways of generating energy, but how to make alternative energy sources with your own hands, i.e. specific instructions, techniques, practical examples. I just really want to start using alternative energy sources at home, because This topic is very promising, interesting, and environmentally significant.I believe that the more people get carried away by this topic, the better it will be for the whole country, and even the world.

    It has already been written here that scientists invented a device for obtaining additional and free energy from power supply networks in volume - how much I consumed, the same amount I got for free. But this device isn’t on the move, not only because there is oil and gas, but just people don’t want to mess with this. Since electricity is not expensive today and there is an opportunity to steal. One inventor wrote an article on such a device, with a note that he would give the documentation for the production for free. This article has long been on the Internet and there is not a single comment. I also made such a device, but my hands do not reach to introduce it at least in the country. If there are interested people, then write, because you can also open a good business.

    There is a widespread belief among the people that you can just put a windmill, or a solar battery - and you are already provided with free electricity. But there is no free electricity. The cheapest is the one on the net. Despite all the increases in electricity tariffs. Because to provide your home with an autonomous power supply system, you need serious investment.

    The system of supplying a country house with electricity includes several main components: first of all, it is a powerful system of storage batteries where the energy supply will be stored. And its supply should be such that for 10 hours of operation of all the necessary electrical appliances in the house, only 10% of the battery energy should be consumed. A controller and an inverter are also needed. Electronics to recharge the batteries will turn on the diesel generator. And only a fuel generator will guarantee the constant presence of voltage in the house. And any windmills and solar panels are installed only to save energy. Although with proper installation, fuel economy is up to 90%! This is very good. However, without a fuel generator so far. After all, the sun and the wind are not always.

    There are two ways to recoup fuel costs: either sell surplus electricity to the network, or have an electric car and charge it from a home power supply system. The first and most important thing to do is to calculate the costs of all this. And their payback period. If the costs do not pay off, then this is just your hobby. In any case, a useful hobby. The cost of an uninterrupted power supply system is comparable to a pair of modern cars. These systems will be advantageous only where there is no mains electricity. Here, the payback is not calculated, and the costs are based on your capabilities.

    There is a future in the Russian Federation, but it must be supported by the state! In particular, why not introduce a green tariff after all, that you and I could establish such systems as these and give away excess energy generated to the same state? Indeed, in this case, the state does not need to invest anything at all. Millions of people themselves will bring electricity by investing their own funds in the installation of such systems. Then the systems themselves will become cheaper due to increased competition.
