Which of the following is not a type of commercial energy firewood Natural Gas Coal Electricity?

What are the types of commercial energy?

By far the most important forms of commercial energy are electricity, coal and refined petroleum products. Commercial energy forms the basis of industrial, agricultural, transport and commercial development in the modern world.

What are the 4 energy sources of fuel?

The primary sources of energy in the environment include fuels like coal, oil, natural gas, uranium, and biomass. All primary source fuels except biomass are non- renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy. There are 6 more fundamental concepts.

What are the 3 forms of energy?

Potential energy is stored energy and the energy of position.

  • Chemical energy is energy stored in the bonds of atoms and molecules. …
  • Mechanical energy is energy stored in objects by tension. …
  • Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together.

Which is not an energy source?

Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
