Renewable and non-Renewable Energies

Renewable energy sourcesWhen we talk Difference Between Renewable and non-Renewable Energies, we refer to the energy sources from which they arise. Renewable energy sources are those that are not exhausted or are renewed in a relatively short time; Non- renewable energy sources are those that are depleted with use or their regeneration is much slower.

Let us remember that energy, the capacity to do work and/or produce heat, is not created or destroyed but transformed. 

is coal renewable or nonrenewable

The different forms in which energy occurs are best known by the sources of origin: solar energy is that which comes from the sun, wind energy is the energy generated by the movement of air, and so on.

Definition of renewable Energy Sources

Renewable energy is that which comes from sources that are not depleted with use or that are regenerated in a short period of time.  Obtaining and distributing them represent a technological, economic and cultural challenge.

is natural gas renewable or nonrenewable

Examples of Renewable Energy Sources

Renewable energy resources offer cleaner alternatives to generate power.

Sun

Solar energy is radiant energy from the nuclear fusion of the elements that make up the sun: hydrogen and helium. Naturally, plants capture solar energy in the process of photosynthesis. On the other hand, solar radiation is the energy engine that heats the earth’s surface, generates winds and maintains the water cycle.

Currently there are two technologies for harnessing solar energy by humans:

  1. Photovoltaic technology: converts solar energy into electrical energy through silicon cells that react with light.
  2. Solar thermal technology: solar collectors use solar energy to heat fluids.

Wind

Wind energy comes from the wind, the movement of air that occurs as a result of changes in temperature on the earth’s surface.

The wind has been used as a power generator since ancient times. The sails of ships in navigation, the windmills to grind grain and transport water are examples of the application of the wind to produce work.

Recently, some countries are basing the generation And electrical energy by means of wind turbines . These huge devices are designed and built to capture faster wind more economically. Wind farms are large-scale installations of turbines.

Definition of non-Renewable Sources of Energy

Non-renewable energy sources are those resources that cannot be recovered in their original form after extracting energy from them.

Examples of Non-Renewable Energy Sources

The energy contained in fossil energies was firstly attained from the sun, through the process of photosynthesis. In due course, the shops and creatures of millions of times ago failed and were deposited, latterly being covered with layers of earth and jewels.

The immense pressure to which these organic remains were subordinated contributed to the metamorphosis into what we now know as fossil energies. exemplifications of them are oil painting and its derivations, coal and gas.

These energy sources are adulterants and creators of hothouse feasts, which beget the effect of global warming.

The use of radioactive material to generate electricity in nuclear plants implies enormous environmental damage and the consumption of non-renewable resources.

A turbine should be installed above 9 meters high, ideally as high as possible, and separated from obstructions (trees, buildings, houses, other towers) about 60 meters.

 This represents a problem in the installation of heavy turbines, which can cause a lot of damage if they fall.

Difference Between Renewable and non-Renewable Energies

Renewable Energies Non-renewable Energies
Depletion
Renewable resources cannot be depleted over time Non-renewable resources deplete over time
Energies
Renewable resources include sunlight, water, wind and also geothermal sources such as hot springs and fumaroles Non-renewable energy includes fossil fuels such as coal and petroleum.
Environmental Impact
Most renewable resources have low carbon emissions and low carbon footprint Non-renewable energy has a comparatively higher carbon footprint and carbon emissions.
Cost
The upfront cost of renewable energy is high. – For instance, Generating electricity using technologies running on renewable energy is costlier than generating it with fossil fuels Non-renewable energy has a comparatively lower upfront cost.
Infrastructure Requirements
Infrastructure for harvesting renewable energy is prohibitively expensive and not easily accessible in most countries. Cost-effective and accessible infrastructure is available for non-renewable energy across most countries
Area Requirements
Requires a large land/ offshore area, especially for wind farms and solar farms Comparatively lower area requirements
