Solar energy is an energy source that converts energy from the sun’s radiant energy into a useful form for human use. When the sun shines on solar panels, solar energy is converted into electricity for our use.
Wind energy is actually a form of solar energy, formed by the uneven heating of all parts of the earth’s surface, the imbalance of pressure distribution in the atmosphere, and the movement of air in a horizontal direction. Wind energy mainly utilizes the rotation of the blades in a wind turbine to produce electricity that can be immediately applied to goods stored in batteries.
Solar energy: solar energy is not limited by geography, almost any area, just in different areas, solar energy utilization efficiency is different. According to current estimates of the rate of nuclear energy production, the sun’s energy is enough to power the earth for tens of billions of years, far exceeding the earth’s lifespan. However, solar energy is greatly affected by weather, geographic location and time of year. Especially on cloudy or rainy days or when there is not enough sunlight in the winter, the efficiency of solar power systems can drop dramatically or even fail to provide energy properly.
Wind energy: wind energy does not damage the natural environment, compared with other energy sources of power generation equipment, wind power generation equipment construction is relatively simple, conducive to the realization of sustainable energy use, in large-scale applications, the overall cost of wind power generation is lower, but more dependent on the environment. And the wind turbine will emit large noise, need some open space, wind power is unstable and not easy to store.
Wind energy is more practical compared to solar energy, solar energy due to the high price, the cost is much higher than wind energy. In power generation, wind energy conversion in 30%-40%, solar energy conversion in about 25%. However, wind energy systems take up a large amount of land for their construction, wind power is generally more common along the coasts, away from areas that need electricity, and can affect birds and other animals. In addition, the noise and visual impacts of wind energy systems are a concern for some. For utilities, wind energy is a better choice.
Modern solar panels can be mounted directly on the roof without taking up too much land, and we can live in areas with strong sunlight, but there is a high potential for safety incidents when living in strong wind conditions. And most families can easily add or clean solar panels, but not everyone has the ability to install wind turbines.
The combination of solar and wind energy is mainly a wind and solar complementary power generation system, which can maximize energy and enhance the stability of the power grid by using solar and wind energy to complement each other. In the event of insufficient sunlight or unstable wind speeds, solar and wind can complement each other in supplying electricity while reducing the pressure on electricity. They can be mainly applied to areas that require large amounts of power supply, such as urban power supply, industrial production, etc.
Solar and wind energy have their own advantages and disadvantages, which energy source is more favorable to you, but also need to choose according to the actual situation.
