What are fossil fuels?

Fossil fuels came from ancient plants and organisms about 360 to 286 million years ago in the Carboniferous period, even before the first dinosaurs came into being which was approximately 240 to 230 million years ago.

In the Carboniferous period, the Earth was covered with dense swampy forests and different types of animals. When those plants and animals died, they drowned to the bottom of the swamp. Over millions of years, the dead plants and animals decomposed under a layer of sand, clay, and other materials and minerals.

What are the different types of fossil fuels?

Different types of fossil fuels were formed depending on organic matter, time, temperature, and pressure.

The three primary kinds of fossil fuels are Oil, Coal, and natural gas.

Believe it or not, according to, currently, fossil fuels power about 80% of the world’s energy!

How is Coal made?

Coal is made when dead ferns, plants, and trees are exposed to heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat to Coal, a carbon-dense black or brownish-black sedimentary rock.

How is Oil made?

Oil is a fossil fuel that has been formed from a large amount tiny plants and animals that have been decomposed because of the pressure and heat.

How is Natural gas made?

Natural gas has the same formation process as Oil; they are a fossil fuel that has been formed from a large number of tiny plants and animals that have been decomposed because of the pressure and heat.

What is Renewable energy?

Oil, Coal, and natural gas are all Non Renewable energy, meaning they can run out over time. On the other hand, renewable energies are energies that can be replenished over time. Some examples of renewable energies are:

  • Solar energy,
  • Wind energy,
  • Hydropower energy,
  • Biomass energy,
  • Geothermal energy,
  • Tidal energy

Solar energy

Solar energy is a sort of energy generated by the Sun. Solar energy can be harnessed from the Sun by solar panels. The panels use the Sun’s light and convert it into electricity. With the help of solar panels, we can do many things in an earth-safe way.

Wind energy

Wind power or wind energy describes the process by which the wind is used to turn an electric generator that converts the kinetic energy from the wind into mechanical power. But basically, wind power or wind energy is the use of wind turbines to generate electricity.

Hydropower energy

Hydroelectric energy is a form of renewable energy that uses the power of water in motion. Most hydroelectric power plants are large dams that control the flow of a fast-moving body of water. When water is released through the dam, it spins a turbine connected to a generator which produces electricity. Then, the water returns to the river on the dam’s downstream side.

Biomass energy

Biomass energy comes from plants or microorganisms living or was recently living. For example, Plants make energy from the Sun in a process called photosynthesis. Believe it or not, this energy is still stored in the plants after they die. Trees, recycled paper, manure, corn, soy, and sugar are all considered biomass. We burn the biomass to get its energy.

Geothermal energy

Geothermal energy is a type of renewable energy taken from the Earth’s core because the core of the Earth (center of the Earth) is about the same as the temperature of the surface of the Sun ~6,000° Celsius. They can use steam from hot water found some miles below the Earth’s surface to turn a turbine that triggers a generator, and as a result, it produces electricity.

Tidal energy

Tidal energy uses the rising and falling of the tides in the sea to create energy. Tides are caused by the combined effects of the gravitational forces of the Sun and moon.

According to national geographic, there are three different ways to get tidal energy.

  • Tidal streams,
  • Tidal barrages, and
  • Tidal lagoons.

For most tidal energy generators, turbines are placed in a fast-flowing body of water created by tides called tidal streams. The tides utilize the movement of water to rotate a turbine to generate electricity.

Why is it importent to increase the use of renewable energy?

Some of the many environmental benefits of using renewable energy are –

  • Renewable energy generates energy that produces no direct greenhouse gas.
  • Renewable energy can reduce some types of air pollution.
  • Renewable energy is also a very reliable source of power because we will never run out of sunlight, wind, and ocean. Still, we are eventually going to run out of nonrenewable energy.
