Concept:
In contrast to renewable energy sources, there are non-renewable energy sources that are known and currently used by the entire world, including fossil fuels (oil, natural gas, and coal), which is the most prominent and common form of them.

It is known that these non-renewable sources of energy are not available everywhere around us and take hundreds of millions of years to form and produce.

When fossil fuels are burned, they produce energy, a process that causes harmful emissions of greenhouse gases, or greenhouse gases, which include carbon dioxide and methane.
Nuclear fuel is considered a non-renewable energy source, but it is environmentally friendly, unlike fossil fuels. Nuclear power plants do not produce greenhouse gases, such as carbon dioxide or methane, during their operation.

Non-renewable energy resources are characterized by scarcity and uneven geographical distribution, and the most important resources are oil, gas, and shale oil. It represents the world's greatest dependence over the past years and up to the present time on non-renewable energy sources, which constitute the primary source of energy production, especially fossil and nuclear energy, but the total dependence on them has had a negative impact on the climate and environment. It has led to global warming and climate change in the world, and many countries have begun to feel its effects in recent decades.
