Abstract
In recent years, solar and wind energy have been increasingly abandoned due to the blind expansion of the new energy industry. Due to the competitive relationships between different types of new energy, reasonable industrial development planning needs to be implemented to not only save the cost of government subsidies but also clarify the investment direction of social capital. Based on the panel data of OECD countries between 2006 and 2018, the stochastic frontier analysis (SFA) was used to measure the efficiency of new energy generation (NEG) and the influencing factors were analyzed in this paper. Results were as follows: the efficiency of NEG in OECD countries is improving; the efficiency of NEG is positively correlated with technical innovation, government policies, economic level, and education level and negatively correlated with urbanization. Based on the empirical results of this study, problems in the development of the new energy industry have been discussed and suggestions to improve the efficiency of NEG have been proposed.
Highlights
With the fast development of new energy and the increasing maturity of technologies in recent decades, new energy products have been accepted and occupy the corresponding market in the economy [1,2,3]. e percentage of new energy to traditional energy has increased to 9.6% in 2017, and the percentage of wind and solar energy in primary energy consumption has increased rapidly [4]
Conclusions. e existing literature focuses on driving factors of new energy generation (NEG) performance evaluation, carbon emission reduction efficiency, and improving power generation efficiency at the technical level
E power generation efficiency of new energy is measured at the economic level, and the influence factors are examined in this paper
Summary
With the fast development of new energy and the increasing maturity of technologies in recent decades, new energy products have been accepted and occupy the corresponding market in the economy [1,2,3]. e percentage of new energy to traditional energy has increased to 9.6% in 2017, and the percentage of wind and solar energy in primary energy consumption has increased rapidly [4]. E percentage of new energy to traditional energy has increased to 9.6% in 2017, and the percentage of wind and solar energy in primary energy consumption has increased rapidly [4]. The proportion of global new energy consumption in primary energy consumption is currently still low, developed countries, including the USA, Japan, and South Korea, are developing new energy as their main future energy source [5]. Many countries have formulated their new energy development plans [6]. Both the “Sino-US Joint Statement on Climate Change” and the “Energy Strategic Action Plan (2014–2020)” state that nonfossil energy will be close to approximately 20% of primary energy consumption by 2030 in China [7]. Hydropower is usually classified as renewable energy rather than new energy
