Final answer:
Yes, natural gas supply and pipeline capacity are expected to be sufficient to meet market demands in the foreseeable future, although this is subject to factors such as public and regulatory concern for carbon emissions.
Step-by-step explanation:
The supply and pipeline capacity of natural gas are expected to be sufficient to meet market demands in the foreseeable future. The United States has abundant supplies of coal and natural gas, with the transportation infrastructure already in place. The recent expansion of shale gas reserves has further increased the production of natural gas in the United States.
However, the future development of coal and natural gas depends on factors such as public and regulatory concern for carbon emissions, as well as the relative price and supply of the two fuels. Regulatory pressure on carbon emissions could lead to the retirement of coal power plants and the addition of natural gas power plants.
Overall, while natural gas supply and pipeline capacity are currently sufficient, future developments will depend on various factors.
