Wind energy pros and cons


Wind energy pros and cons: The development of wind energy around the world, in recent years, is very rapid. The leaders at the moment are China and the United States, however, the rest of the world is advancing this promising direction of "clean" energy, based on an inexhaustible natural resource - wind energy. They install every year more and more wind generators in the world, and there is a tendency towards the further spread of technology.

Let's look at the wind energy pros and cons,

Wind Energy pros and cons


Benefits



1. Wind energy is a fully renewable energy source. Because of the action of the sun, air currents constantly move in the atmosphere, for the creation of which it is unnecessary to extract, transport, and burn any fuel. The source is inexhaustible.

2. There are no harmful emissions in the process of operation of a wind power plant. This means that there are no greenhouse gases, nor any production waste. The technology is environmentally friendly.

3. The wind station does not use water for its work.


4. The wind turbine and the main working parts of such generators locate at a considerable height above the ground, the wind turbine occupies a small area on the ground, So we can use the surrounding space for household needs, various buildings and structures, for example, for agriculture, we can place wind turbine there.

5. We can use wind energy generators for isolated territories, where electricity cannot be delivered by conventional methods, and autonomous provision for such territories is perhaps the only way out.

6. After the commissioning of a wind farm, the cost per kilowatt-hour of the electricity generated in this way is significantly reduced. For example, in the United States, they specifically investigate the operation of newly installed stations, optimize these systems, and thus reduce the cost of electricity for consumers up to 20 times from the initial cost.

7. Maintenance during operation is minimal.


Disadvantages:


1. Dependence on external conditions at a particular moment. The wind may be strong, or it may not be at all. To ensure a continuous supply of electricity to the consumer in such unstable conditions, a system of storage of electricity of significant capacity is required. In addition, infrastructure is required to transfer this energy.

2. The construction of a wind installation requires material costs. Sometimes, regional investments are attracted, which is not always easy to provide. The construction of the project itself is very expensive. The infrastructure mentioned above is an important part of the project, which also costs money.

On average, the cost of 1 kW of installed capacity is $ 1,000.

3. Some experts believe that windmills distort the natural landscape, that their appearance violates the natural aesthetics of nature. Therefore, large firms have to resort to the help of professionals in design and landscape architecture.

4. Wind turbines produce aerodynamic noise that can cause discomfort to people. For this reason, a law has been passed in some European countries, according to which the distance from the windmill to residential buildings should not be less than 300 meters, and the noise level should not exceed 45 dB during the day and 35 dB at night.

5. There is a small chance of a bird colliding with the blade of a windmill, but it is so small that it hardly needs serious consideration. But bats are more vulnerable, because the structure of their lungs, in contrast to the structure of lungs of birds, contributes to fatal barotrauma when a mammal enters the area of ​​low pressure near the edge of the blade.

Despite the disadvantages, the environmental benefits of wind generators are obvious. For clarity, the operation of a 1 MW wind generator can save about 29,000 tons of coal or 92,000 barrels of oil over 20 years.

So, these were some wind energy pros and cons that we have mentioned above.
