Global renewable energy has maintained a steady growth in recent years, mainly fostered by national policies and increasing demand. Analyzing the experience of renewable energy development in developed countries can be important to provide reference and guidance for its adoption in other countries. First, we compare and summarize definitions of distributed generation from 18 leading countries and organizations in renewable energy. On this basis, we provide three basic characteristics for successful distributed generation using renewable resources. Then, we empirically analyze the distributed and centralized development of renewable energy in Germany with focus on wind and photovoltaic power. We determined that 95% of the photovoltaic generation and 85% of the wind power generation is distributed in Germany, suggesting that the most suitable generation mode for renewable energy is the distributed approach.
Most governments are giving great importance to the development and utilization of renewable energy worldwide. By 2016, 173 countries set renewable energy development goals, and 146 countries adopted a variety of supportive policies. Likewise, cities, communities, and businesses are pioneering the rapidly growing 100% Renewable Energy initiative, which is playing a crucial role in driving the global energy transformation. Other factors also promote the development of renewable energy, such as financing incentives, energy security attention, environmental concern, and the growing demand for modern energy services in developing countries and emerging markets.Also in 2016, renewable power generation (excluding hydropower) increased by 14.1%, creating the largest increase record (53 million metric tons of oil equivalent). More than half of the renewable energy growth is driven by the adoption of wind energy, and although solar energy accounts for only 18% of the available renewable energy, it contributes with about one-third of this growth. As the largest market and producer of renewable energy in the world, photovoltaics and wind power in China have maintained a steady growth in recent years under the support of national policies. Renewable energy in China is mainly developed under the centralized mode. However, deficiencies of power grid and transmission channel construction and curtailment of wind, photovoltaic, and hydro power have limited the development rate of renewable energy[1, 2]. Therefore, it is necessary to analyze the experience of renewable energy development in developed countries and determine the main characteristics of distributed and centralized generation to create reference and guidance for the selection of the most appropriate renewable energy development mode in China. We also provide a detailed analysis of the renewable generation modes adopted in Germany to offer a more comprehensive perspective on its development.
