Question: Natural gas is a premium fuel in great demand all over the world for home heating and electric power generation. It produces only half the greenhouse gases of coal when burned, and when processed, none of the toxic sulfur gases. What do you think the author means when he describes the burned-off (fl ared) natural gas as "unwanted?" Describe the geography of the region in Nigeria where the oil is extracted and pumped to shore. As of 2007, how much gas was being flared in Nigeria annually, and how does this amount compare to energy demands of the African continent? Need Assignment Help?
