Coal, natural gas and oil accounted for 87 percent of the world's primary energy consumption last year, the group reported in a new "Vital Signs Online" report.
Fossil fuel is a term used to describe a collection of energy sources formed by natural processes like anaerobic decomposition during the Carboniferous age million of years ago.
During the Carboniferous age, the earth was covered with swamps teeming with plants and organisms. When these plants and organisms died, they sunk to the bottom of these swamps and oceans.
In the course of millions of years, the dead plants and animals began decomposing under huge layers of clay, sand and other minerals. The fossil fuels include petroleum, coal and natural gas. In fact, the whole world is dependent on fossil fuels to fulfill their daily energy needs.
Though adoption of renewable energy sources has increased sharply in last decade, still it will take some more years to reduce our dependence on fossil fuels drastically. The consumption of these fossil fuels is going at an high rate which means once we have used up all of them, we need to rely on alternative sources of energy such as solar, wind and hydro power to meet our daily needs.
This sounds quite scary, but yes, this is the truth. Though fossil fuels have their own advantages but the damage that they cause to the environment can affect entire ecosystem. This world has no choice but to use the existing fossil fuels until scientists come out with a technology that can produce energy at same rate without affecting the environment.
Different kinds of fossil fuel form depending on a blend of factors including organic matter, temperature, time and pressure conditions in the course of decomposition.
Three main kinds of fossil fuels exist today; oil, natural gas, and coal. Most of the coal we utilize in the modern day was formed approximately million years ago. During that time, a large percentage of the earth consisted of steamy swamps.
As the trees and plants died, their remnants were deposited at the bottom of the swamps, resulting in huge layers of plant material. The layers of plants ultimately formed a soggy, thick material known as peat.
Oil was formed from the remains of dead plants and animals that were deposited at the bottom of the ocean. Over the years, the dead plant and animal remains got buried deeper and deeper by accumulated sediment causing heat and pressure to rise. The application of heat and pressure without the presence of oxygen anaerobic decomposition led to decomposition of these dead plant and animal matter, leading to the formation of oil.
Natural gas was formed in the same way as oil; only the intensity of heat and pressure significantly increased causing oil to decompose further into gaseous form. Fossil fuels have a wide range of applications including generation of electricity, transport fuels, making products like plastics, cosmetics, and even certain medicines.
Only profiting companies talk good about fossil fuels. In truth, fossil fuels have numerous upsides that hardly come up in debates.
That said, here are the advantages to fossil fuels: Cheap source of energy Statistically, fossil fuels are some of the cheapest sources of fuel on the planet. Although the process of extraction and refinement is relatively expensive, the return on investment is pretty remarkable.
Today, innovative technologies are available that can extract fossil fuels with high degree of efficiency, substantially reducing the overall cost. In fact in the modern day, extraction of fossil fuels is cheaper than installing wind and solar technologies.Energy Information Administration - EIA - Official Energy Statistics from the U.S.

From India's proposed megawatt solar power plant to China's efforts to curb smog, renewables, alternative fuel vehicles and energy efficiency are moving firmly into the mainstream.
The small, mountainous nation of Bhutan is getting in on the act too. Bhutan could provide itself completely with self-produced energy. The total production of all electric energy producing facilities is 8 bn kWh, which is % of the countries own usage.
Despite this, Bhutan is trading energy with foreign countries. the InternAtIonAl JournAl on Green Growth And development ArtIcle Sustainable Energy in Bhutan: Opportunities for Energy Efficiency SHERAB JAMTSHO1 Abstract: In terms of Bhutan’s energy trade, while the country exports clean energy, the country imports fossil fuels.
On the demand side, transport and industry sectors are the major consumers. The U.S. Energy Information Administration (EIA) released its International Energy Outlook (IEO) this week, reporting that petroleum and natural gas will likely remain the top two global fuels through EIA is forecasting “rapid” natural gas consumption growth over the next two decades as well as strong petroleum consumption growth, as the following graphic from the report shows.
Achieving % renewable ‘total energy’ – for power, transport and heat – will require us to reduce unsustainable demand (overconsumption), as well as increasing energy efficiency, and shifting our transport and heating systems from liquid and gas fuels to electrical power.
