摘要
Solar energy plays an essential role in mitigating fossil fuels shortage and resolving, environmental issues caused by burning fossil fuel, and global warming. Resources such as oil, natural gas and coal are diminishing day by day. Tradition energy consumption causes environment problem. Renewable energy has become an inevitable road and extensive consensus for the international community to respond to climate change. As a clean renewable energy, solar energy is gradually becoming an important alternative energy. Thus, the photovoltaic industry witnesses a rapid global growth. However, the deployment of photovoltaic modules on a large scale has also caused certain influence on the ecological environment and climate. The author summarized the impacts of photovoltaic power plants on the ecological environment and climate developed globally, nationally and locally, analyzed and discussed the feedback effect of photovoltaic power plants construction on the environment at different scale. The research results show that there is no consistent conclusion on the feedback effect of building photovoltaic power plants. The major mechanism is that the decrease of solar radiation on the surface causing by shielding effect of photovoltaic modules and the absorption and conversion of solar radiation, which then affects the surrounding environment, and causes the change of ecological environment and climate. The physical mechanism appears complex. And the research to the impact of photovoltaic power plant on the ecological environment and climate in China is still in the elementary stage. Therefore, the mechanism needs further research.
