How is electricity primarily generated in a power plant?

Electricity generation in a power plant primarily involves converting various energy sources into electrical energy. This method encompasses the use of fossil fuels (like coal, natural gas, and oil), nuclear energy, and renewable sources (such as wind, solar, and hydroelectric power).

Fossil fuel power plants typically burn coal or natural gas to generate steam, which drives a turbine connected to a generator. Nuclear power plants use the heat produced from nuclear fission to create steam. Renewable energy sources, such as wind and solar power, are also increasingly integrated into the electricity generation mix. Wind turbines convert kinetic energy from the wind into electricity, while solar panels capture sunlight and convert it into electrical energy using photovoltaic cells.

While other answer choices mention specific methods like solar panels or wind power, they represent only a subset of the overall spectrum of energy conversion processes that occur in power plants. Thus, the comprehensive nature of choice B accurately reflects the diverse means by which electricity is generated in power plants across various energy sectors.
