Taiwan lacks natural energy, if not to develop nuclear power they have to face power shortage problem, so renewable energy has become the focus of energy policy, but the president of the Taiwan Research Institute, Zaiyi points out that the state should focus on the stable supply of energy, but not all on the regeneration energy development.Zaiyi Wu thinks that the development of renewable energy sources, is bound to have a traditional coal-fired power as backup power, but Taiwan is the world's first regional carbon emissions per capita, Taiwan can not just blindly develope renewable energy, but should focus on the rationalization of tariff, on the one hand, use subsidies to stimulate the applications of energy-saving products,reducing Taipower losses.In terms of energy-saving effect about 80% of LED products , if to use of LED lighting,Taiwan can save 22.4 billion degrees of power, Taiwan's three nuclear plants just make 40 billion kWh of electricity, showing that the energy-saving LED lighting effects, would be effective to improve energy usage.According to the price on the part in Taiwan, Zaiyi Wu points out, energy prices are unreasonable, but if Taiwan has the capability to continue to take the lowest? He points out that Taiwan's electricity is even much lower than Shanghai, Beijing."Price should be rationalized,"Zaiyi Wu stresses again,in the situation of swings in energy prices and the global trend of greenhouse gas emissions, we should not only think negatively against the potential economic impact,but also should make good use of this emerging international opportunity for the transfer of low-carbon economy.He also pointes out to develop from that energy efficiency industry,while the LED industry is a very useful effect of the industry.
