Abstract. Algeria has experienced a notable agricultural development driven by a prosperity in market gardening in plastic greenhouses due of the favorable climatic conditions and the government’s policy. For that, a survey has been conducted in order to determine the energy use pattern for greenhouse vegetable production, also to estimate the greenhouse gas (GHG) emission for this system of production in Biskra province, Algeria. The results revealed that the total energy required for vegetable protected production is 119.68 GJ per hectare where the infrastructure was the highest energy consumer followed by the electricity and fertilizers with a share of 22%, 20% and 19%, respectively. The energy use efficiency (energy ratio) was calculated as 0.82, showing the inefficiency use of energy in the protected vegetable production. The inputs of farmyard manure, followed by infrastructure and electricity in greenhouse vegetable production generated the highest proportion of gas emissions with values 35%, 33% and 23%, respectively. According to these results, management of electricity and diesel fuel consumption are possible using solar energy to decrease total GHG  emission in greenhouse vegetable production in Biskra province.
