Concerns about energy supply security and actions to address climate change in the world have promoted the rapid development of renewable energy technologies and industries worldwide, such as photovoltaic power generation and wind power generation, which are growing at an annual rate of more than 20%. Renewable energy has become an important alternative energy source for energy diversification, global climate change and sustainable development. Especially in the past two years, with the great fluctuations in international oil prices and the implementation of the Kyoto Protocol, renewable energy development has become a hot spot in the international energy field, and has received widespread attention in many countries around the world. By the end of 2006, the global renewable energy power generation capacity exceeded 200 million kilowatts, including small hydropower of about 80 million kilowatts, wind power of 75,000 kilowatts, geothermal power generation of 10 million kilowatts, solar power generation of more than 7 million kilowatts, solar photovoltaic power generation annual growth rate exceeded 60%, the production capacity is close to 2 million kilowatts.
Energy saving advantages of solar lighting
With the economic development, China's lighting power will be greatly improved, and the research and application of green energy-saving lighting will be paid more and more attention. As a cold light source product, solar LED lighting fixture has the characteristics of high cost performance, environmental protection, safety and reliability, stable quality, long service life, easy installation and maintenance, etc. It can be widely used in green space lighting, highway lighting, advertising light box lighting, urban modeling landscape. Lighting and home lighting systems, but the high investment in solar LED lighting is a bottleneck.
At present, lighting consumption accounts for about 20% of the total power consumption. Reducing lighting power is an important way to save energy. In order to achieve this goal, the industry has researched and developed a variety of energy-saving lighting fixtures, and achieved certain results. However, the requirements for green lighting are still far away, and it is imperative to develop and apply new light sources that are more efficient, reliable, safe and durable.
By the end of 2006, China's renewable energy utilization totaled 200 million tons of standard coal (excluding the traditional use of biomass energy), accounting for about 0.5 percentage points, achieving renewable energy accounted for 10% of the country's total primary energy consumption in 2010. The goal has taken a solid step. At present, China is promoting the domestic market development of photovoltaic power generation from the following aspects: First, start power transmission to village projects; Second, use photovoltaic power generation in special projects, such as World Expo, Olympic Games, etc.; Third, build photovoltaic in desert areas Power station; Fourth, mobilize some cities to start the roof plan; Fifth, study and formulate electricity price policy to improve the competitiveness of photovoltaic power generation (90% of PV products exports and the lack of domestic market, may limit the long-term development of China's PV industry. Once the foreign PV industry There are changes in policies or measures to restrict imports to protect domestic industries. In recent years, China’s large-scale PV projects will face difficulties.
