Wind or Solar, which energy source is more efficient? Know here

Wind Vs Solar Energy: Both wind and solar are big sources of renewable energy. Both are unlimited and do not produce any greenhouse gases while generating electricity. These do not cause pollution, which can prevent global warming from increasing. If we look at the cost also, in most places solar and wind energy is cheaper than fossil fuels. In this sense, both of them are more beneficial than oil and coal, but which source is more efficient among solar energy and wind? Today we will compare these two and know their advantages and disadvantages.

Wind Vs Solar Energy: Which has more efficiency?

When it comes to efficiency, wind energy is ahead. Wind turbines convert about half of the air passing through them into electricity. That means its efficiency is around 50 percent, whereas solar panels lag behind in this matter. Solar panels come with 20-25 percent efficiency. This means that solar panels are able to convert only about 25 percent of the sunlight that falls on them into electricity.

What are the advantages and disadvantages of wind energy?

advantages

• Apart from efficiency, wind energy is also ahead in terms of availability. Nowadays, such turbines have come which can generate electricity even from the wind blowing at very slow speed. As the wind speed increases, electricity production also increases. The wind turbine continues to generate electricity even when the wind blows at night. Like solar panels, it does not work only during the day.
• The size of wind turbines has increased in recent times. According to the World Economic Forum, wind turbines have become approximately 60 percent longer. This is necessary because as the ground height increases, the wind also becomes stronger. The air flow is affected due to buildings and trees etc. on the ground, but there is no such problem at height. Therefore, a taller turbine produces more electricity.

Loss

A major disadvantage of wind energy is that you cannot install turbines everywhere. Although small turbines to be installed in homes have now arrived, their use is still limited. Wind turbine requires free space. Secondly, their running makes a lot of noise, due to which they are planted away from residential areas. This is the reason why they have not reached every house like solar panels. The cost of wind turbine is also preventing it from becoming popular. You will have to spend a lot of money for a big wind turbine.

What are the advantages and disadvantages of solar energy?

Loss

• As we have discussed above, the efficiency of solar panels is low and they do not work at night. Their efficiency also reduces due to cloud cover during the rainy season. Therefore, they cannot be called a completely reliable source of energy.
• Its second disadvantage is that solar panels are made of silicon and other rare metals, which require mining. Mining has a negative impact on the climate. If this is kept in mind then it is not a clean energy source like wind energy.

advantages

Despite the low efficiency of solar panels, more people are using them. The biggest reason for this is easy installation and maintenance. Solar panel is very easy to install and it does not require much space. You can easily install solar panels on the balcony or terrace of your house. On top of that, their cost is also much lower than that of wind turbines. Once installed, the panel does not require much maintenance and will continue converting sunlight into electricity for many years. It does not create any noise and requires very open spaces.
