When we use oil or gas, we use waste from animals, trees and plants, which turns into fossil fuels in the ground. the latter, once used, will produce energy and gas, which will be absorbed by plants and the rest will be degraded in nature by other natural processes.
Fossil fuels are technically more efficient than safer compared to renewable sources of energy like solar and wind.
However, alternate use of by-products from fossil fuels are highly productive and have high value, which act as offsets to the environment pollution caused from fossil fuels.
Though coal and oil reserves are limited in availability, gas reserves on other hand are found to be replenished quickly and are considered safer and reliable alternate option to solar and wind energy.
I think you want to say fossil fuel is renewable, that is true; but this will take many decades or centuries as the theories say. So for us it is non-renewable..
Some countries lack fossil fuel resources, and developing renewable energy can enhance their national energy security.
All energy sources have negative effects. But they differ enormously in size: as we will see, fossil fuels are the dirtiest and most dangerous, while nuclear and modern renewable energy sources are vastly safer and cleaner. From the perspective of both human health and climate change, it matters less whether we transition to nuclear power or renewable energy and more that we stop relying on fossil fuels.
Energy has been critical to the human progress we’ve seen over the last few centuries. As the United Nations rightly says: “energy is central to nearly every major challenge and opportunity the world faces today.”
But while energy brings us massive benefits, it’s not without its downsides. Energy production can have negative impacts on human health and the environment in three ways.
The first is air pollution: millions of people die prematurely every year as a result of air pollution. Fossil fuels and the burning of biomass – wood, dung, and charcoal – are responsible for most of those deaths.
The second is accidents. This includes accidents in the mining and extracting of fuels – coal, uranium, rare metals, oil, and gas. It also includes accidents in transporting raw materials and infrastructure, the construction of the power plant, or their maintenance.
The third is greenhouse gas emissions: fossil fuels are the main source of greenhouse gases, the primary driver of climate change. In 2020, 91% of global CO2 emissions came from fossil fuels and industry.1
No energy source is completely safe. They all have short-term impacts on human health, either through air pollution or accidents. And they all have long-term impacts by contributing to climate change.
But, their contribution to each differs enormously. Fossil fuels are both the dirtiest and most dangerous in the short term and emit the most greenhouse gases per unit of energy. This means that there are thankfully no trade-offs here: low-carbon energy sources are also the safest. From the perspective of both human health and climate change, it matters less whether we transition to nuclear power or renewable energy and more that we stop relying on fossil fuels.
Nuclear and renewables are far, far safer than fossil fuels

Before we consider the long-term impacts of climate change, let’s look at how each source stacks up in terms of short-term health risks.
To make these comparisons fair, we can’t just look at the total deaths from each source: fossil fuels still dominate our global electricity mix, so we would expect that they would kill more people.
*** This is my point if view, fossil fuels are safer compared to other forms of energy existing on earth. Because the excessive exploitation of solar energy or wind energy causes an imbalance in the ecosystem because it is exploited more than it can support.
