The centralized facility could combine crop residues and natural gas to generate electricity.
Recent years have witnessed a significant increase in the production and consumption of oil and natural gas.
The introduction of natural gas can be seen as a change in an exogenous variable, which we expected to modify sources' behaviour and program's performance.
Stoves are mainly natural gas, and gas utility prices are low.
Coal and natural gas prices are determined by the supply elasticities of their respective resource bases.
This also happened in the late 1970s when construction of the natural gas network was delegated to the state-owned oil and gas utility.
The streets are of dirt, the electrical power is weak and there is no natural gas, sewer system, public lighting or garbage service.
Presently the best available coal and natural gas plants have efficiencies of about 45 per cent and 52 per cent respectively.
