The advantages of using natural gas rather than coal are the following,
Natural gas is present in large amount than coal.
Natural gas is less costly than other fossil fuel sources of energy.
It increases security by decreasing dependence.
Natural gas is more environmentally friendly.
Natural gas is much safer to store.
It is reliable.
Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.
The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.
