The energy we use to produce power like electricity and heating has an effect on the environment. In order to make environmentally friendly choices, it is critical to consider the energy source on which your supplier is based. For the most part, we have relied on fossil fuels such as coal, oil, and natural gas for energy. However, because this is a non-renewable energy source, it will eventually run out. Renewable energy is defined as energy produced from naturally replenished resources. We can encourage environmental sustainability by using renewable energy sources. Natural resources are materials or objects derived from the earth. Natural resources are classified into two types. These are natural resources that are renewable. They are referred to as renewable because they can be produced again and again and never run out.
Renewable energy
The resources which are available in the earth in unlimited supply for instance sunlight , air , water , land etc are known as renewable resources. These contribute equally to the benefits of human beings and the environment.
Types of renewable energy
Stars are composed of spherical plasma that is held together tightly by gravitational force. The Sun is a type of star as well. The Sun is the star that is closest to Earth. During the night, millions of small stars can be seen with the naked eye. Historically, some of the most prominent stars were classified as asterisms or constellations. Because of the distance between the earth and the stars, they all appear very small to our eyes. They are, however, enormous, with some even larger than Earth and other planets in the solar system.
Solar energy: – It is derived from the Sun’s energy. Solar energy is captured and used to generate heat or electricity via panels or mirrors. Photovoltaic (PV) cells It is derived from the Sun’s energy. Solar energy is captured and used to generate heat or electricity via panels or mirrors. Solar cells directly convert sunlight into electricity. This heat absorption panel is used by solar thermal collectors to generate electricity.
Wind energy: – Wind energy can be used to get mechanical power to electric generators with turbans, allowing them to function as pumping systems. It is made up of a rotor that is linked to a generator. Wind energy is used to generate electricity. A windmill is a structure with blades that convert wind energy into rotational energy. It generates electricity using renewable resources.
Geothermal energy: – it is energy derived from thermal energy stored in the earth. Volcanoes and hot beverages used to capture this energy and then transformed or used by industries for water heating and other tenacities.
Hydropower: – Hydropower is the energy produced by the use of water. It is created by utilising tides, which is recognised as tidal energy. Ocean surface vibrations are also used to generate electricity, which is known as wave energy.
Bioenergy: – Bioenergy is created from biomass, which is animal and plant waste. This biomass contains chemical energy and, when burned, provides bioenergy. The heat produced is being used to generate electricity and power generators.
Non-renewable resources
The formation of all fossil fuels is very similar. Earth’s geography was very different hundreds of millions of years ago, even before the appearance of the dinosaurs. A large portion of the planet was covered by broad, shallow seas and swamps.
These ancient wetlands were home to plants, algae, and plankton. Photosynthetically, they took in the sun’s rays and converted them into energy. Upon their death, the organisms sank to the bottom of the ocean or lake. When plants and animals died, their stored energy was released.
It took a long time for the dead plants to sink to the seafloor. As more rocks and sediment were deposited on top, the pressure and heat in the earth increased. Fossil fuels were created from plant and animal remnants in this environment (coal, natural gas, and petroleum). A large number of non-renewable energy sources can be found in large subsurface pockets (known as reservoirs).
Types and examples of non-renewable resources
Fossil fuel- Fossil fuels are achieved by the dead remains of plants and animals. Examples: natural gas, Coal, Oil, etc.
Nuclear fuel- Uranium is a very general example of nuclear fuel. Nuclear power delivers 6 % of total energy and 13-14 % of world electricity.
Advantages of Non-renewable resources
1. Non-renewable resources are affordable, for example, diesel and oil.
2. Easily accessible and compatible.
3. It is easy to store.
Disadvantages of non-renewable resources
When the energy is all used up it cannot be replaced again.
It escalates greenhouse gases.
Examples
The non-renewable energy resources are as follows:
Coal
Nuclear
Oil
Natural gases
Conclusion
Natural resources should be used wisely at all times. Natural resources must be conserved. To conserve something means not to use it up, spoil it, or throw it away. This is particularly true when it comes to non-renewable resources. Even renewable natural resources, however, can run out if they are all depleted or overused. We must also guard against pollution of our natural resources. Pollution occurs when humans release harmful chemicals and other materials into the environment. This problem can manifest itself in the form of oil spilled in water, toxic chemicals in the air, or garbage dumped on the side of the road.
