Renewable energy sources do not replace coal, oil or gas plants, they only meet part of the growing demand. In spite of the impressive development of wind power, Spain is now 3 times more dependent on fossil fuels for electricity generation than a decade ago Regardless of the growing share of renewable energy sources, we burn up more and more fossil fuels every year.
June 11, by April Klazema For years, the world has run on fossil fuels, with humankind using these ancient non-renewable resources to power cars, airplanes, machinery, trains, home heating systems, and more. Modern technology is working toward developing renewable energy methods that would replace these fossil fuels as the main source of gas and power for the world, largely because fossil fuels have become a scarce and wildly expensive property.
Worst of all, since fossil fuels were derived hundreds of millions of years ago by a long and laborious geological process — transforming from plants into a spongy composite called peat, which in turn morphed into the fuels we use today, they are completely un-renewable. There is no hope of more fossil fuels being created, or of scientists figuring out how to synthesize petroleum or coal in a lab through experimentation of plant matter.
Because of this, mankind is in a tight spot as far as energy is concerned. Still, while scientists strive to create new alternative energy possibilities or to increase the efficiency of existing ones, such as solar powerfossil fuels remain the most robust and effective means we have of powering vehicles and other machinery in reliable fashion.
To understand precisely why that is, we need to look at the different types of fossil fuels and examine why they have long made for such effective sources of energy.
The Different Fossil Fuels Though different terms are occasionally used that are interchangeable for each, there are three primary varieties for fossil fuels.
These are coal, oil, and natural gas. Coal Of the three types of fossil fuels, coal is the only one still in a solid state. It appears as chunks of midnight black rock, which are harvested from the Earth by workers in mining operations.
Coal is composed of five different elements: In fact, because of these differing elemental make-ups, there are actually three different types of coal, each with different energy properties.
The highest in energy content is anthracite coal, which is harder and has a higher distribution of carbon than the other varieties.
Lignite is high in oxygen and hydrogen instead of carbon, while bituminous occupies a sort of happy medium between the two extremes.
Coal is a dynamic fossil fuel in terms of how it is used. In any case, coal today is used for everything from producing steel and cement to keeping the lights on in homes and businesses. Over million years, according to scientific consensus.

The three main forms of fossil fuels are coal, oil and natural gas. These three are also known by different names, such as petroleum for oil, and each type of fossil fuels exists in a different chemical state. Coal has been used for centuries for heat and to power steam engines.
Of those million years, civilizations have been making use of oil for about five or six millennia. From the Sumerians who used oil to invent asphalt to the Native Americans who used it for treating wounds and waterproofing canoesoil has a long history of maximizing efficiency and convenience for human civilization.
Today, we think of oil as the fuel that we pump into our cars at gas stations, but refined gasoline is not what comes out of the ground at oil wells.
On the contrary, crude oil is the type of petroleum that occurs naturally. In the United States, we get our crude oil from multiple sources, though unfortunately, most of it is not mined domestically and must be purchased from the Middle East.
Once crude oil arrives in the United States, it is taken to refineries, where it is processed into fuel that we can actually use. From any given gallon of crude oil, these refineries produce a range of different oil substances that are then used for different applications. A little less than half of the average barrel of oil is refined into gasoline, which is indeed the type of petroleum that we use to fuel our cars.
However, other parts of the barrel are refined into oil for asphalt, jet fuel, kerosene, lubricants, and more.Having one fewer child is the most effective way an individual would have to fight climate change.

Fossil Fuels The energy-rich substances formed from the remains of plants, animals, and other organisms that lived hundreds of millions of years ago that died and remains piled up under layers of sand, rock and mud and over time, heat and the pressure of the .
The world will need greatly increased energy supply in the next 20 years, especially cleanly-generated electricity. Electricity demand is increasing much more rapidly than overall energy use. Nuclear power is the most environmentally benign way of producing electricity on a large scale.
Coal: Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in the development of anthracite and even graphite.
