Top 3 Primary Sources of Energy

We depend on various sources of energy to generate power. Because the world runs on electricity, all different sources of energy are primarily used to produce electricity. Since we heavily rely on electricity, we usually don’t realize how often we use it. Some of the many things we depend on each day that run on electricity include cars, refrigerators, televisions, heaters and air conditioners, cell phones, and so much more.


How Electricity is Delivered

Consumers Many wonder how exactly electricity works. Consumers receive electricity through a complex network. Electricity is generated at power plants and then the energy is moved from the power plant to an electrical substation, referred to as power transmission. The transmission lines carry electricity long distance and distribution lines carry electricity to homes.

Electricity Comes From Different Sources Because electricity is generated from the transformation of primary energy sources, including fossil fuels and nuclear power, it is a secondary energy source. Primary sources are those that can be used directly as they appear in the natural environment.


Fossil Fuels

There are numerous sources of energy, with many continuously being discovered. But, they haven’t reached the point where they can be used to provide the power that modern life demands. Listed below are three of the primary sources of energy used today.

Fossil Fuels When most think of the different sources of energy, they think of natural gas, coal, and oil. Together, these are actually one source – fossil fuels. Fossil fuels are currently the world’s primary energy source. We heavily depend on fossil fuels for everyday use, including vehicles, heat, and to provide electricity.


Nuclear Power

Nuclear Power Like fossil fuels, nuclear power is used to generate heat and electricity as well. It is also one of the major renewable sources of energy in the world. Nuclear energy is a vital part of a clean energy strategy. Electricity produced from nuclear power plants releases no carbon dioxide, avoid billions of emissions.


Solar Energy

Solar Energy Simply put, solar energy is energy produced by the sun. Today, solar energy is becoming more popular because it’s a cleaner, more sustainable form on energy, and is more cost effective. Examples of solar energy applications include solar powered refrigerators, radios, and air conditioning systems.
