Third solar photovoltaic system technology and equipment battery special training course Review of hot issues and development trends of photovoltaic industry Presenter: Shenzhen graduate school Harbin Institute of Technology Zhu Zhenye The world energy situation and the demand for renewable energy Before the middle of this century, energy structure will undergo fundamental change The production and use of fossil fuel energy to peak oil, coal and natural gas as the representative of the coming towards us, according to the latest forecasts, the production and use of peak oil and natural gas will come in 2015 near; fossil fuel production and use of the total will come to peak around 2030. In the fossil fuel oil, coal and natural gas production and use of more than 20 years before the peak, stepping up the development and utilization of solar energy as the representative of the renewable energy is very necessary and urgent. This period is the incubation period for renewable energy. The term incubation period refers to the time before renewable energy costs are equal to fossil fuel costs. In renewable energy breeding period, the need for strong support of national policies and regulations. Trends in energy structure in the world Requirements and forecasts for alternative speeds for renewable sources of energy Owing to the large use of fossil fuels, there are two prominent problems: 1) the gradual depletion of fossil fuels; (2) the great destruction of the environment. Therefore, renewable energy sources will gradually replace traditional fossil fuel sources in the change of energy structure. This substitution should meet three requirements: 1) to ensure the normal development of the world economy and society; 2) to meet the requir
