A first step toward saving oil could be to increase the efficiency of its conversion into electricity, heat, and motive power. In the industrial sector, currently only 55% of the energy is actually used. Domestic and small consumers, who represent not only the largest but also the expanding consumption areas, use only 45%, while transport uses only 17%. The remainder is lost through conversion, transport, and waste heat. The gradual replacement of oil in energy generation by coal and nuclear energy could have an even greater effect. This includes the partial or complete replacement of gasoline by methanol or by ethanol, perhaps from a biological source
