How Long Will An Energy Source Last Us?

Introduction

Energy is required for the evolution of life forms on earth. We obtain energy from different sources. Everything that we use today – food, clothes, houses, vehicles, fuel, notebooks, furniture, cooking gas, utensils, toys, roads, etc. is obtained from resources on the earth. The natural resources that we use today are the prime source of energy for the day-to-day activities of humans, without which we would still be lurking around in the Stone Age. But are they being replenished at the rate at which they are being used up? In this article, we will discuss how long an energy source will last us.

Renewable and Non-renewable Resources

All things that are useful to us are called resources.  Renewable and non-renewable are the two types of energy resources.

Renewable Resources

A renewable resource is an energy source that can be replenished within a short period of time. Whereas, the non-renewable resources take a significant amount of time to be replenished by the environment.

Non-renewable Resources

The non-renewable resources comprise fossil fuels like coal, petroleum, oil, etc., the usage of which has detrimental effects on the environment. Comparatively, renewable resources are more environmentally-friendly. They include energy from the sun, tides, wind, biomass, etc.

How Long will an Energy Source Last?

We can split our discussion into two directions. We first talk about how long a renewable energy source will last. Renewable energy resources are called ‘renewable’ because they are constantly renewed or regenerated.

  • The energy from the sun, the movement of the waves, the flow of the river – these are some activities that have been happening for millions of years and will continue to happen in the future. They are constant and reliable sources.
  • Tidal energy, solar energy, tidal energy, wind energy, hydroelectric energy, geothermal energy, etc. will never get exhausted as they can be generated at the same rate at which they are being used.
  • When we talk about non-renewable energy sources, they are limited in quantity. They cannot be renewed easily once they are depleted. They take thousands of years to be formed. At the present rate of consumption, these resources will be exhausted in less than a hundred years.

It is very important to use non-renewable energy resources in a judicious manner. Otherwise, our future generations will not be left with any of them.

Frequently Asked Questions – FAQs

Q1

What is renewable energy?

Renewable energy is energy that is produced from natural processes and continuously replenished. A few examples of renewable energy are sunlight, water, wind, tides, geothermal heat, and biomass.
Q2

How many types of renewable energy sources are there?

  • Solar energy
  • Wind energy
  • Hydroelectric energy
  • Biomass energy
  • Hydrogen and fuel cells
  • Geothermal power
  • Tidal energy
Q3

What is non-renewable energy?

Non-renewable energy is energy from fossil fuels such as coal, crude oil, natural gas, and uranium. Non-renewable energy is limited resources that will eventually run out over the time frame. Non-renewable energy is the energy that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames.
Q4

What are the advantages of non-renewable energy?

  • The non-renewable source of energy is affordable. For instance diesel and oil.
  • It is easily accessible and more compatible.
  • The non-renewable source of energy is easy to store.
Q5

What is solar energy?

Solar energy is the energy emitted by the sun in the form of radiant light, which is then harnessed by humans using a variety of methods such as solar heating, photovoltaic cells etc.
