Energy can be named as existence itself, starting from the life of a cell till electricity, everything has its own quantitative energy. The 21st-century planet earth has the ability to do work and gain supplies from natural resources to provide a livelihood for humanity which vastly becomes easy to access. Starting from finding natural resources until inventing numerous amount of advanced technology, energy is the pyramidion of all reality itself. 

The supplies of energy may be loosely classified into 2 main categories, depending on their source and their impact on nature. These are Renewable and Non-renewable energy. Renewable energy is generated from various natural resources and doesn’t emit carbon compounds within the environment. Non-renewable energy comes from sources that will run out or will not be renewed in our lifetimes—or even in many, many lifetimes. Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. (Carbon is the main element in fossil fuels).

Though both Renewable and Non-renewable energies have their own advantages and disadvantages to our environment and causing numerous climate changes over the years. We could change our way of living for this energy and consume it into green sources. 

Let us further look at the sources of Non-renewable energy and what are their uses are.

Non-renewable energy

Natural Gas

Accident is the name of the greatest of all inventors. First-ever discovered natural resource of energy is natural gas, it was discovered accidentally in ancient China around 500 BC (or 1000 BC) as it resulted from the drilling for water resources from the ground. In the Ziliujing District of Sichuan, they found a way to transport gas seeping from the ground to the crude pipeline of bamboo to boil salt water to extract salt.

Moreover, in 1626 the identification of natural gas happened in the western continent, and during the 19th-century natural gas was used almost exclusively as a source of light. From the making of the first the Fredonia Gas Light Company in the Americas till bunsen burner invented by Robert Bunsen. Once effective pipelines began to be built in the 20th century, the use of natural gas expanded to home heating and cooking, appliances such as water heaters and oven ranges, manufacturing and processing plants, and boilers to generate electricity.

Coal

Coal was known to be man’s source of heat and light, more than 3000 years ago Chinese were first to use coal.  The first recorded discovery of coal in this country was by French explorers on the Illinois River in 1679, and the earliest recorded commercial mining occurred near Richmond, Virginia, in 1748.  On April 13, 1750, Dr. Thomas Walker was the first recorded person to discover and use coal in Kentucky.

Petroleum

They say the war between countries was because of natural resources like petroleum, it is surely a beneficial and highly used natural resource of humans daily life. Petroleum was first discovered by the Chinese in 600 BC and transported in pipelines made by bamboo. However, Colonel Drake’s heralded discovery of oil in Pennsylvania in 1859 and the Spindletop discovery in Texas in 1901 set the stage for the new oil economy.

Gradually after the discovery of Petroleum, it vastly gave other types of petroleum for humans daily usage. Types of unrefined petroleum include asphalt, bitumen, crude oil, and natural gas. (See also the fossil fuel; hydrocarbon; oil; petrochemical; petroleum production; petroleum refining; pitch lake; tar sand.)

Results of Non-Renewable Energy 

Advantages 

  1. Abundant & Accessible
  2. They provide a large amount of quantitative energy
  3. They can be found very easily
  4. They are relatively low cost and they can be transported relatively easily.

Disadvantages

  1. Environmental pollution is one of the major disadvantages of Non-Renewable energy sources
  2. They are non-renewable and unsustainable
  3. The finding and harvest of this sort of natural resources is a dangerous process
  4. They may contribute to public health issues

Due to the usage of these Non-Renewable natural sources, the rapid change of climate is occurring from the emission of carbon molecules. The panel also concluded there’s a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane, and nitrous oxide have caused much of the observed increase in Earth’s temperatures over the past 50 years. 

Many researchers claim to boycott Non-Renewable natural resources for a solution of improvement to the planet earth climate changes. Environmental activist Greta Thunberg, a young visionary who spoke in a U.N climate action summit speech about taking action towards world leaders for a change in global disastrous effects, which is damaging our future generations as well as our current global warming issues. 

Though these fossil fuels has given humanity its needs and purposes, it is time for drastic measures of changes to take place on the planet earth.

The World of Renewable Energy 

Solar Energy

The energy that is derived from the sun’s heat and radiation is known as solar energy. It is categorized as renewable energy because the source is abundant and harnessing the same does not reduce its heat or radiation and it does not impact the environment because solar energy doesn’t produce carbon emissions. This is the most common source of energy and can be used especially during day time to produce electricity to supply the demands on hot days. The following technologies have been developed to use solar energy 

Photovoltaic Systems

Generating electricity for solar energy
Solar water heaters

Wind power

The concept of wind is known to everyone and the wind cycle is not the new topic to understand. As long as the sun is there the wind is generated. The kinetic energy generated from wind can be transferred into electrical energy by using wind turbines. These turbines are usually set up on high altitudes to use the wind pressure. This source of energy is also termed as renewable as the wind is a free source and by harnessing the same, they do not contribute to air or water pollution

The wind energy is harnessed since centuries for uses like:

Pumping water
Grinding grain
Wind Knitting

Water Energy

Hydropower is the energy generated from flowing water. The gravitational energy from the water is released as it falls. The flow can be in terms of melting snow or streams and rivers. The energy from the water is harnessed by creating damson the rivers.

The energy is generated from the water stored in a reservoir at the dams. The water is released with force to generate the energy which can be used to generate electricity. This is a renewable source of energy as the source is natural and free once the dam is constructed.

Biomass energy

Energy generated from natural wastes is called as biomass energy. 

The sources can be:

Scrap lumber
Forest debris

Certain crops
Manure
Food waste during processing and after use

It is also considered renewable energy because the waste will always generate and more of manages forests that will replenish the environment and their organic wastes.

Geothermal energy

Geothermal energy is the heat from the Earth. It’s clean and sustainable. The geothermal energy is generated from the shallow groundhot water natural geysershot rocks, or the molten rocks available in the form of Magna. The technologies are developed to harness geothermal energy. 

It can be used for:

Geothermal Electricity
Space heating and cooling

Food preparation (by using steam)
Hot spring bathing and spas (by use of the earth heat for shower and toilet)
Agriculture
Aquaculture
Greenhouses

Conclusion

For quite a long time we are utilizing these natural resources for our necessities of surviving, for the most part, utilization of Non-Renewable energy in view of simple access has demonstrated the awful impacts happening to our current living by contaminating life sources, occupying lands and animal extinction, misuse of reliable energies, and monetizing in realism.

Furthermore, we should utilize the riches in building a green world with renewable energy, a universe of sharing among one another. Learn new things, head out to places where we approach whatever we want to learn and experience with our habits of acknowledgment. Make use of money in safeguarding for natural resources and prevent contamination from high pollution, in the event that if we don’t make changes to happen, at that point in 10 years from now the entire planet will be near the precarious edge of terrible minutes of living.

It is conceivable with the assistance of every worldwide leader and rich individuals around the globe to develop a high practical undertaking based on living society, with no obstructing with compelling force to nature and promoting contamination. Jacque FrescoThe Venus Project, has given us the vision of reality work out as expected from sci-fi. His venture claims everything to be genuine in our coming age to live in success and live with no mischief to mother earth. May his vision materialize in this coming age.
