　　The digestion temperatures in northern China do not reach the optimum point for continuous production of gas without heating.In cold weather, it is difficult to generate large amounts of gas with stable performance without heating and the heating must be cheap, reliable, environmental friendly, high performance and efficient.All these properties are available when using solar energy.The relation between ambient temperature and the temperature inside the digesters is one of the most important factors.The gas production has been a significant affect by temperature inside the digester, as the temperature decreases sharply, the gas production also decrees sharply.So we propose using greenhouse and parabolic trough solar concentrators as a good solution of these problems.
