7.6 Economic and Environmental Performance
Simulated economic and environmental performance of different cooperative
patterns in various scenarios is shown in Table 7.2. When total cost is minimized,
Scenarios 2 and 3 both result in simultaneous reduction of cost and CO 2 emissions. In Scenario 1 (urban dominant cooperation), the emissions reduction ratio is
relatively low and the total cost increases by 1.3% (compared with Scenario 0).
When the environmental objective is minimized, annual energy costs dramatically
increase, although CO 2 emissions are reduced to relatively low levels in all three
scenarios. Scenario 1 has better economic and environmental performance than
Scenario 2, in contrast to the situation with minimum cost. Therefore, natural gas
is a good option to reduce CO 2 emissions, especially when utilized in a CHP
system. In addition, from either an economic or environmental viewpoint, Scenario 3 (urban-rural mutual cooperation) is recognized as the best alternative with
the lowest energy cost (economic objective) and CO 2 emissions (environmental
objective).
