Abstract: Tibet is short in fossil energy, but rich in renewable energy sources, such as biomass, hydro, solar, geothermal, and wind power. This potential energy supply in Tibet can be juxtaposed to what drives Tibetan energy consumption its economic motivation and its cultural traditions. Currently, biomass heavily dominates Tibet's energy consumption. In 2003, total energy consumption was about 2 million tce (ton coal equivalent), traditional biomass accounting for nearly 70%. The rarified atmosphere and use of outdated stoves, make for a very low combustion efficiency, utilizing 10-15% of the potential energy of biomass. With population and economic growth, traditional use of biomass has become the principal factor responsible for deforestation, grassland degradation, desertification, and soil erosion. To eradicate the negative impact of the traditional use of biomass on the eco-environment in Tibet, a series of effective countermeasures are investigated. Among these are improved efficiency of stoves, widespread use of solar energy, hydroelectricity as a substitute for traditional biomass, and the development of biogas.
