Abstract:Understanding energy security must consider its objectivity, subjectivity and intersubjectivity. Starting from the conceptual framework can be found, as the U.S. shale gas revolution was deepened, and today the world"s energy supply present under the new situation of "two more than strong" resource nationalism, energy geopolitical conflict problems such as frequent, the world"s energy security situation is very serious. Overall situation at present, the main energy consumer is keen to establish a self-sufficient under abnormal sustainable energy system. Solar photovoltaic, with its unique advantage has become the national energy security strategy choice. Leading photovoltaic powers represented by Germany and Japan has turned their emphases on strategies and polices to technology innovation and market promotion, and secretly transferred heavy polluting and high energy-consuming manufacturing part to developing countries mainly as China. Faced with primary resource contradictions caused by increasing need for clear resources but with severe deficiency, the clean use of photovoltaic resources should be upgraded within the national security strategies in China, along with the adoption of a series of policy measures beneficial to lever domestic photovoltaic demands, ensure the photovoltaic technology renovation, strengthen the market supervision, enhance the energy bank construction and reinforce the strategic environmental assessment.
