| Summary/Abstract |
This paper analyses the potential of renewable energy for power generation and its energy, environmental and economic implications in Pakistan, using a bottom up type of long term energy system based on the MARKAL framework. The results show that under a highly optimistic renewable portfolio standard (RPS) of 80%, fossil fuel consumption in 2050 would be reduced from 4660 PJ to 306 PJ, and the GHG emissions would decrease from 489 million tons to 27 million tons. Nevertheless, price of the electricity generation will increase significantly from US$ 47/MWh under current circumstances (in the base case) to US$ 86/MWh under RPS80. However the effects on import dependency, energy-mix diversity, per unit price of electricity generation and cost of imported fuels indicate that, it may not be desirable to go beyond RPS50. Under RPS50 in 2050, fuel consumption of the power sector would reduce from 21% under the base case to 9% of total fossil fuels supplied to the country. It will decrease not only GHG emission to 170 million tons but also will reduce import dependency from 73% under the base case to 21% and improve energy diversity mix with small increase in price of electricity generation (from US$ 47/MWh under the base case to US$ 59/MWh under RPS 50).

| Summary/Abstract |
China is striving for coordinated regional economic development and to solve the energy shortage in eastern China through a western China development plan with one focus being energy development and west to east energy transfer. This paper describes Western China Sustainable Energy Development Model (WSED) to evaluate various energy development scenarios for western China. The model includes a Western China MARKAL model, a Computable General Equilibrium Model for Western China (WCGE), and an Energy Service Demand Projection Model (ESDP). The ESDP provides energy service demand projections for the Western China MARKAL model, while the WCGE provides macroeconomic inputs for the ESDP and analyzes the impact of different energy development scenarios on western China economy. A reference scenario and several different west to east energy transfer scenarios with and without consideration of the water constraints and the endogenous technology learning are presented. The modeling describes the energy consumption, carbon emissions, water consumption, energy investment cost, and the impact on western China GDP of the different scenarios through the year 2050. These results have implications on sustainable energy development policies and sustainable west to east energy transfer strategies.
