It is understood that since always give priority to with natural gas has increased investment in the photovoltaic industry of Singapore. The article content is for reference only. UN secretary-general's special representative for Rachel Kyte said, southeast Asian countries use the health risks of coal should be incorporated into economic analysis, governments also need to further promote the renewable energy investment. At the meeting, the United Nations representative pointed out that the coal for southeast Asian nations is no longer the most economic cheap energy, intelligent systems engineering and urged governments to consider other renewable energy sources. 'Photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging regenerative heating equipment, photovoltaic stents can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, solar photovoltaic (pv) network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar photovoltaic network published the article for the purpose of the information, solar energy regenerative heating does not mean that agree with his point of view or confirm its description. Heat transfer system of photovoltaic solar net news: recently, cold and heat source system component of heat transfer system, the secretary general of the United Nations climate summit envoy Luis Alfonso DE Alba said in a telephone conference, carbon emissions is growing in southeast Asia in recent years, southeast Asian countries need to end our dependence on fossil fuels as soon as possible, since 2020 to phase out all of the coal-fired power plants. At the same time, intelligent systems engineering for the Philippine islands from the remote areas of the city, on Rachel Kyte added: & other; Renewable energy don't have to rely on the central control of power grid, also can reduce environmental pollution from coal-fired power plants. The wire for the climate action summit was held in New York before the media communication.
