Renewable energy refers to energy that can be used continuously in human life. Its energy source will not be depleted due to use, and its use has a small impact on the environment.
Renewable energy is increasingly used in buildings, which can provide sustainable energy for buildings, reduce dependence on traditional energy, and reduce building energy consumption and environmental pollution. Here are some applications of renewable energy in buildings:
Solar energy: Solar energy is one of the most common renewable energy sources and can be converted into energy by installing solar panels on the roof or facade of a building. To provide electrical energy to power buildings.
Wind energy: Wind energy is also a common renewable energy source. Wind turbines can be installed on the roof or facade of a building to convert wind energy into electrical energy to provide electricity for the building.
Ground source heat pump: Ground source heat pump is a technology that uses underground heat energy for air conditioning and heating. It can convert underground heat energy into the heat energy required by the building by installing heat exchangers underground around the building. Achieve energy conservation and emission reduction.
Biomass energy: Biomass energy refers to the technology of using biomass as energy. Biomass can be converted into heat or electricity by installing biomass burning equipment to provide energy for buildings.
Hydropower: Hydropower refers to the technology that uses water flow or water pressure to generate power. Water energy can be converted into electrical energy by installing a hydroelectric generator or turbine to provide electricity for buildings.
The application of these renewable energies can enable buildings to achieve energy self-sufficiency, reduce dependence on traditional energy, reduce building energy consumption and environmental pollution, and promote sustainable development of buildings.
Permanent land acquisition is generally based on the machine position of 25*25 meters. If there is a box-type transformer, it must be added. The land occupied by the booster station is also subject to permanent land acquisition.
Attempts to use wind power to generate electricity began as early as the beginning of the twentieth century. In the 1930s, Denmark, Sweden, the Soviet Union and the United States applied rotor technology from the aviation industry and successfully developed some small wind power devices.
This kind of small wind turbine is widely used in windy islands and remote villages. The cost of generating electricity is much lower than that of a small internal combustion engine. However, the power generation capacity at that time was relatively low, mostly below 5 kilowatts.

China’s development:
2006 In 2007, China had a total of 6,469 wind turbines, of which MW units accounted for 21.2%. In 2007, this proportion jumped to 38.1%, an increase of 16.9 percentage points. In 2007, the cumulative installed capacity of global wind power reached 94,100 MW, an increase of 27% from 74,200 MW in the previous year.
In 2007, China’s wind power installed capacity was 6.05 million kilowatts, achieving the 2010 target three years ahead of schedule.planning goals; in the six years from 2001 to 2007, China's wind power installed capacity increased 14 times; in 2007 alone, China's wind power installed capacity increased by 3.449 million kilowatts, which is more than the cumulative total of China's wind power in history. With the rapid development of the wind power industry, the supply of wind power equipment exceeds demand.
