World concerns about the security of energy supply and action to address climate change, to promote the rapid development of renewable energy technologies and industries worldwide, such as photovoltaic, wind power generation in the annual growth rate of more than 20%. Renewable energy has become an important alternative energy to diversify energy sources to address global climate change and achieving sustainable development. Especially in the recent two years, as the international oil price fluctuations as well as the Kyoto Protocol implementation come into force, renewable energy development become the hot spot in the field of international energy, and has been gained widespread concern in many countries of the world. By the end of 2006, the global renewable energy power generation installed capacity exceed 200 million kilowatts, including small hydropower of about 80 million kilowatts, wind electricity 75,000 kilowatts, geothermal power generation 10 million kilowatts, solar power generation more than 700 million kilowatts, solar photovoltaic average annual growth speed of more than a 60% of the production capacity of close to 2 million kilowatts.
Energy-saving advantages of solar led lightings
Along with economic development, China’s electricity for lighting will greatly improve, the research and application of green energy-efficient lighting gain more and more attention. Solar led lightings and led panel lights as a cold light source with a higher cost, green, safe, reliable, stable quality, long service life, easy installation and maintenance characteristics, green lighting, road lighting, advertising light boxes lighting, urban landscape modeling lighting and home lighting system can be widely used, but the higher one-time investment of solar led lightings is the bottleneck of the development.
Lighting consumption accounts for about 20% of the entire electricity. Consumption is an important way to save energy, and reduce lighting electricity. To achieve this goal, the industry has research and develop a variety of energy-saving lighting equipment, and certain results. However, the requirement is also far from the “green light”, the development and application of more efficient, reliable, safe, durable new street light is imperative.
By the end of 2006, China’s renewable energy capacity is totaled 200 million tons of standard coal (excluding traditional biomass), accounting for about 0.5 percent. For 2010, renewable energy accounted for 10% of the national total primary energy consumption, the goal has taken a solid step forward.
