Abstract
Low-carbon energy technology is the most fundamental way to control carbon emissions. The Sanjiangyuan region in Qinghai Province must put environmental conservation in first place during development, because of its important function of national ecological protection. The comprehensive benefits of photovoltaic technology in this area need to be evaluated. In this paper, a new multicriteria decision model (MCDM) is established, with the four dimensions of “environment-society-economy-population”, and 16 specific indicators are developed by combining the coupling coordination degree (CCD) and the decision-making trial and evaluation laboratory (DEMATEL) method. MCDM can contribute to screening out key indicators that should be of high concern. The evaluation results show that the four dimensions of “environment-society-economy-population” in the Sanjiangyuan region are highly correlated, and the PPAT is creating a coordinated development; the elements of population and environment play a decisive role in the comprehensive benefits based on five key indicators and three indicative indicators. The paper provides suggestions for the local government to further implement the PV poverty alleviation industry, under the condition that the natural environmental capacity of the region and the natural ecosystem are fully respected and undisturbed.
Highlights
In response to climate change, the greatest threat to humanity, a low-carbon economy has become the consensus and trend of global economic development [1]
Photovoltaic poverty alleviation technology (PPAT) is an industry derived from the combination of semiconductor technology and low-carbon energy technology, a means to achieve regional industrial poverty alleviation through energy conversion, emerging rapidly in developed regions such as Europe, America, and Japan, and in the Middle East, South America, and other regional countries
This paper aims to assess the following: (1) to view PV technology application as a transformation process of regional decarbonization development, and evaluate its comprehensive performance in conjunction with the time series of industrial implementation for dynamic evaluation and even prediction; (2) to take the Sanjiangyuan region, which bears important national ecological protection functions, as the object of evaluation, to consider the special ecological status, which determines that the socio-economic development of this area must take ecological environmental protection as a prerequisite, and investigate how the application of photovoltaic technology has a multifaceted impact on the ecological environment, social economy, and demographic development of the region
Summary
In response to climate change, the greatest threat to humanity, a low-carbon economy has become the consensus and trend of global economic development [1]. There has been considerable research on the development status, main features, and problems of low-carbon energy technologies in China [5,6,7,8]; the low-carbon energy industry has made remarkable achievements in terms of global market share, scale of development and application, and level of technological innovation, and it makes more progress with each passing day. Photovoltaic poverty alleviation technology (PPAT) is an industry derived from the combination of semiconductor technology and low-carbon energy technology, a means to achieve regional industrial poverty alleviation through energy conversion, emerging rapidly in developed regions such as Europe, America, and Japan, and in the Middle East, South America, and other regional countries. As one of China’s strategic emerging industries, the photovoltaic industry has developed into an industry in which
