Differentiate between renewable and non-renewable energy sources

Jharkhand Polytechnic 6th Sem previous question paper 2021

Renewable energy sources are those that can be replenished over a relatively short period of time, either through natural processes or human intervention. These sources of energy include wind, solar, hydro, geothermal, and biomass. They are often referred to as "clean" sources of energy because they do not emit greenhouse gases or other pollutants into the atmosphere, and their use does not contribute to global warming or other environmental problems.

On the other hand, non-renewable energy sources are those that are finite and cannot be replenished once they have been depleted. These sources of energy include fossil fuels such as coal, oil, and natural gas. They are often referred to as "dirty" sources of energy because their extraction, processing, and use can have significant environmental impacts, including air pollution, water pollution, and habitat destruction. In addition, the use of non-renewable energy sources contributes to climate change, as the burning of fossil fuels releases large amounts of carbon dioxide and other greenhouse gases into the atmospheres

Renewable energy sources

Renewable energy sources are sources of energy that can be replenished naturally in a relatively short period of time, typically within human lifetimes. They include solar, wind, hydro, geothermal, and biomass energy. These energy sources are considered renewable because they are continuously replenished by natural processes, such as the sun's energy, wind patterns, water cycles, and the Earth's internal heat. Renewable energy is becoming increasingly important as a means of reducing greenhouse gas emissions and combating climate change, as they emit little to no greenhouse gases during their operation.
Here are some of the main types of renewable energy sources, with a brief description of each:

Solar Energy : Energy generated by capturing sunlight and converting it into electricity or heat.

Wind Energy: Energy generated by using wind turbines to convert the kinetic energy of the wind into electricity.

Hydro Energy: Energy generated by using the flow of water in rivers, tides, and waves to turn turbines and produce electricity.

Geothermal Energy: Energy generated by tapping into the Earth's internal heat, typically by pumping water deep into the ground and using the steam produced to generate electricity.

Biomass Energy: Energy generated by burning organic materials such as wood, crops, or waste products to produce heat or electricity.

These are some of the most common and widely used forms of renewable energy sources, and many countries are investing heavily in these technologies to reduce their reliance on fossil fuels and reduce greenhouse gas emissions.

Non renewable energy sources

Non-renewable energy sources are sources of energy that cannot be replenished in a relatively short period of time, typically over human timescales. These energy sources include fossil fuels such as coal, oil, and natural gas, as well as nuclear energy. Non-renewable energy sources are finite, meaning that once they are depleted, they cannot be replaced, at least not within a meaningful timeframe.

Fossil fuels are formed over millions of years from the decayed remains of ancient plants and animals. These fuels are found in underground reservoirs and are extracted using various methods, such as drilling and mining. Nuclear energy is produced by the fission of uranium atoms, a process that generates a large amount of heat that can be used to generate electricity.

Non-renewable energy sources have been the mainstay of the world's energy system for many decades, but they have significant environmental impacts, including air pollution, water pollution, and greenhouse gas emissions, which contribute to climate change. As a result, there is a growing need to shift towards renewable energy sources to mitigate these impacts and reduce our reliance on non-renewable energy sources.

These energy sources have been the mainstay of the world's energy system for many decades, but they have significant environmental impacts, including air pollution, water pollution, and greenhouse gas emissions, which contribute to climate change.

The extraction and use of fossil fuels can also have negative impacts on local communities and ecosystems, including habitat destruction and disruption of traditional livelihoods. In addition, nuclear energy carries risks of radiation exposure and the potential for catastrophic accidents, such as the 1986 Chernobyl disaster in Ukraine and the 2011 Fukushima disaster in Japan.

As a result, there is a growing need to shift towards renewable energy sources to mitigate these impacts and reduce our reliance on non-renewable energy sources.
