Dead life forms such as plants and plankton like creatures are covered by layers and layers of rock, mud and sand many hundreds of kilometres deep, resulting in their fossilisation.
The high pressure and bacteria combine to make oil and natural gas deep within the earth’s core. These slowly rise to the surface until they are stopped by cap rock and this is what oil company’s drill through in order to search for the natural reserves underground.
Biofuels are Different
Biofuels are made with biomass (biological material from living or recently living organisms) there are many kinds, for example biodiesel involves growing crops that contain large amounts of natural oil, these plants then go through a refining process and subsequently are mixed in with regular diesel to power cars. Bio petrol is made in a similar way; plants are refined to make a natural ethanol.
Using these types of fuel aren’t as damaging to the environment as using fossil fuels is as they release less harmful gases in to the air. Most of the emissions that are produced are taken in by flowers and trees naturally.
Are they Renewable?
In a certain sense fossil fuels are renewable.
It just takes a couple of hundred of million years for the process to occur, whilst biofuels take much less to produce. Biofuels are also easier to adopt by the population, since they can just use the new fuels in their old cars.
If we take hydrogen or electric cars for example, you have to buy a whole new car, and the info-structure is not yet in place to support a full switch over to these types of vehicles.
Making an Effort
One thing we can definitely see is that the human race is making the effort and trying to switch to more eco-friendly alternatives to fossil fuels by putting in the effort and time to research and study these new industries.
In years to come as fossil fuels become less and less widespread we will see a range of new and innovative discoveries in these fields resulting in even more eco friendlier methods of sustainability.
