A renewable energy source means energy that is sustainable – something that can’t run out, or is endless, like the sun. It means sources of energy that are alternative to the most commonly used non-sustainable sources – like coal.

Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.

Renewable energy sources are energy sources that are always being replenished. They can never be depleted. Some examples of renewable energy sources are solar energy, wind energy, hydropower, geothermal energy, and biomass energy.

Air and water are renewable natural resources too. There is one other type of renewable natural resource. It includes sources of power like sun and wind energy.

Desalination of seawater is considered a renewable source of water, although reducing its dependence on fossil fuel energy is needed for it to be fully renewable.

Non-renewable resources are things that are extracted or mined from the Earth, such as petroleum, coal and metals. Some non-renewable resources are recyclable in that they can be recovered from their prior use to be used again. A good example of this would be aluminum from aluminum cans, old cars or other products.

Wood is a renewable resource.

Wood is considered humankind’s very first source of energy. Today it is still the most important single source of renewable energy providing about 6% of the global total primary energy supply. Wood fuel is a fuel, such as firewood, charcoal, chips, sheets, pellets, and sawdust.

There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels.

Renewable resources are solar energy, wind energy, geothermal energy, biofuels, cultivated plants, biomass, air, water and soil. In contrast, non-renewable resources are those that are available to us in limited quantities, or those that are renewed so slowly that the rate at which they are consumed is too fast.

Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).

Here is a list of 10 examples of non-renewable energy resources available out there in the world.

• Fossil fuels.
• Crude Oil.
• Coal.
• Uranium.
• Natural Gas.
• Tar Sand.
• Steel.
• Phosphate.

Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago.

Fossil fuels are fantastic at their job; that is, producing energy. Earth’s fossil fuel reserves were formed over millions of years as the organic material of ancient plants and microorganisms (not dinosaurs) were compressed and heated into dense deposits of carbon—basically reservoirs of condensed energy.

Coal

Fossil fuels cause local pollution where they are produced and used, and their ongoing use is causing lasting harm to the climate of our entire planet. First and foremost, damaging the world’s economy is not the way to deal with climate change.

If fossil fuels run out one day, electricity failure will happen. This will produce an undesirable occurrence in hospitals in low-to-middle income countries. When fossil fuels are not available, surgeries will be affected halfway. Ventilators and a lot of medical treatment machines will stop working.

1. Renewables replace fossil fuel energy on the grid. In the U.S. and in virtually every region, when electricity supplied by wind or solar energy is available, it displaces energy produced by natural gas or coal-fired generators.

Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years. Yet, renewable energy is not popular enough, so emptying our reserves can speed up.

Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.

about 47 years

Petroleum, coal, natural gas and orimulsion are the four fossil fuel types.

Pros and cons of fossil fuels

• Fossil fuels are not renewable energy sources.
• Fossil fuels pollute the environment.
• In the case of irresponsible use, they can be dangerous.
• Easier to store and transport.
• It is really cheap.
• It is more reliable than renewable energy.

Fossil fuels get their name because they are literally made from fossils — dead organisms (mostly plants) that didn’t decay because they were squashed under water or mud with no oxygen. The plants that were buried deep at sea were converted to oil and gas, and those buried in swamps became coal.

Biomass is biological material derived from living, or recently living organisms. Fossil fuel such as coal, oil and gas are also derived from biological material, however material that absorbed co2 from the atmosphere many millions of years ago. …

Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

While the advantages of biomass energy are plenty, there are also some shortcomings, including:

• Biomass energy is not as efficient as fossil fuels. Some biofuels, like Ethanol, is relatively inefficient as compared to gasoline.
• It is not entirely clean.
• Can lead to deforestation.
• Biomass plants require a lot of space.
