Question

classify the energy resources with an example​

Answer 1

Answer:

Coal. Oil, natural gas & biomass like wood. Examples of other primary energy sources as found on earth are nuclear energy from radioactive substances, geothermal energy , potential energy due to earth's gravity etc. Secondary energy sources are usually converted from oil ,natural gas or coal.

Answer 2

Energy resources can be roughly classified in three categories: renewable, fossil, and nuclear.

Fossil energy resources are obtained from dead plant and animal deposits created over the long history of the planet. These resources are vast, but limited, and are not renewable. Until recently fossil fuels have provided for the majority of humanity’s energy demands. These resources mainly include coal, oil, and natural gas.

Renewable energy resources are forms of energy that are naturally replenished on our planet. Examples of traditional renewable resources are hydropower and biomass (e.g., plant fuels such as wood traditionally have been used throughout history, mostly for heating). Modern renewable resources include wind, wave, tidal, solar, and geothermal. Some forms of fuels created from biomass (plants and animals) also fall under this category.

Deposits of certain radioactive elements in Earth’s crust can be classified as nuclear energy resources. These resources are used as fuel for nuclear fission-based power plants. The amount of these rare radioactive elements is limited on our planet and cannot be replenished. Over the years, there has been some research on fusion power but it is still not proven to be a feasible energy resource. This form of energy conversion aims to harvest the energy from sustained fusion of hydrogen atoms into helium [15].
