Nowadays, as environmental issues become more and more serious, people have begun to understand the importance of environment protection. Using green and renewable energy resources, PV power plants generate essential and widespread social benefits.

First, PV power plants use renewable resource, and help to diversify energy supply sources. With the increase of oil and coal production, non-renewable energy reserves are becoming less and less and will eventually dry up. The development of New energy sources using are of strategic importance. On February 28, 2005, China passed the People's Republic of China Renewable Energy Law, which clearly stipulates that the government encourages and supports grid-tied power generation using non-fossil energy sources, such as wind, solar, water, biologic, and oceanic energy sources. On November 11, 2014, Chinese Chairman Xi Jinping said that China will peak CO₂ emission around 2030 (the earlier the better), and will use up to 20% of primary energy which is not derived from fossil fuel. The utilization of solar energy meets the national policies on environment protection and energy conservation, and helps to effectively reduce regular energy consumption (especial coal), diversify energy sources, and protect the environment.

Secondly, PV power generation can reduce CO₂ emission, mitigate the greenhouse effect, and protect the environment. As described in several official publications, generating electricity of 1 kWh using thermal energy will consume an average of 0.35 kg of standard coal, and burning 1 ton of standard coal will emit 2.6 tons of CO₂. Building a 30 MWp PV power plant will produce 45 million kWh of electricity, reduce coal consumption by 15,750 tons, and reduce CO₂ emission by 40,950 tons in the first year. In its entire life cycle, the PV power plant can reduce coal consumption by 376,417.5 tons and CO₂ emission by 978,685.5 tons. In short, the PV power plants on energy conservation and reducing CO₂ emission, is very significant for companies as well as for countries.

Thirdly, PV power plants increase the usage ratio and value of land. The Tonking solar-agricultural dual-axis tracking PV power plants can be built on rooftops, water, or waste land (such as gobi and desert) to increase the usage and value of land. The Fenglin 30MWp solar-agricultural tracking PV power plant is the largest one of its type in the world in terms of stand-alone capacity.

In addition, PV power plant construction can promote the local economic growth and employment. Industries that can benefit from PV power plant construction include building materials, transportation, and the tertiary industry. After the power plant starts producing electricity, the power plant itself can also drive local economic growth.

Lastly, the PV industry makes the world cleaner and safer, and provides abundant energy supplies.

Solar energy is inexhaustible, clean, and renewable, and has unique advantages and great potential. Making full use of the solar energy not only conserves energy, reduces CO2 emission, and promotes local economic growth, but also makes global energy supply sustainable.
