The correct answer is: D. gas-fired power project.
An atomic power project is a power plant that uses nuclear fission to generate electricity. A hydro-electric project is a power plant that uses the power of moving water to generate electricity. A thermal power project is a power plant that uses heat to generate electricity. A gas-fired power project is a power plant that uses natural gas to generate electricity.
Gas-fired power plants are the most common type of power plant in the United States. They are relatively inexpensive to build and operate, and they can be started and stopped quickly, which makes them well-suited for meeting peak demand. However, gas-fired power plants also emit greenhouse gases, which contribute to climate change.
Atomic power projects are less common than gas-fired power plants, but they are becoming more popular as the cost of nuclear power decreases. Nuclear power plants are very efficient at generating electricity, and they do not emit greenhouse gases. However, nuclear power plants are also very expensive to build and operate, and they produce radioactive waste that must be carefully disposed of.
Hydro-electric projects are the least common type of power plant in the United States. They are only feasible in certain locations where there is a large body of water with a significant drop in elevation. Hydro-electric projects are very efficient at generating electricity, and they do not emit greenhouse gases. However, they can have a negative impact on the environment, as they can disrupt the flow of water and damage fish habitats.
Thermal power projects are the oldest type of power plant. They are still widely used, but they are becoming less common as other types of power plants become more efficient. Thermal power plants emit greenhouse gases, which contribute to climate change.
