Energy Sources and Nuclear Power

Front

Origin of energy in fossil fuels and biomass fuels

Back

The energy in both fossil fuels and biomass fuels ultimately comes from the sun.

How energy flows through a nuclear power plant to produce electricity

Back

Energy flows from the splitting of uranium atoms (nuclear fission) which generates heat. That heat then boils water to create steam, which turns a turbine to spin a generator, ultimately producing electricity.

Why coal, petroleum, and natural gas are called fossil fuels

Back

They are formed from the remains of dead animals and plants.

Front

Formation of coal, petroleum, and natural gas

Back

Coal primarily forms from decomposed plant matter in swampy environments, while petroleum and natural gas originate from marine organisms like algae and zooplankton that settled on ancient seabeds.

Front

Kind of rock associated with coal, petroleum, and natural gas

Back

Coal, petroleum, and natural gas are all found primarily in sedimentary rocks.

Front

Naturally occurring element used in nuclear fission

Back

The naturally occurring element used in nuclear fission is Uranium.

Front

Nuclear fission vs. nuclear fusion

Back

Nuclear fission is the process of splitting a heavy atom into smaller atoms, releasing energy, while nuclear fusion is the process of combining two light atoms to form a heavier atom, also releasing energy.

Front

How a nuclear power plant creates energy vs. a fossil fuel power plant

Back

A nuclear plant does not produce combustion byproducts, making it a low-carbon emission energy source, unlike a fossil fuel power plant, where heat is created by burning coal, oil, or gas, creating large amounts of greenhouse gases.

Front

Why nuclear power plants are not widely used despite high electricity production

Back

Nuclear power plants are not widely used due to significant concerns around safety, the management of radioactive waste, high construction costs, and public perception of risk associated with potential accidents.

Front

Why the majority of our energy comes from nonrenewable resources

Back

The majority of our energy comes from nonrenewable resources like fossil fuels (coal, oil, and natural gas) because they are readily available, relatively cheap to extract, and have high energy density.
