Every day the world population grows, as does the demand for natural resources. Natural resources are things found in nature that are necessary or useful to humans. However, the most used and in-demand natural resources are non-renewable, which means they have limited availability and cannot last forever. Most of these non-renewable resources are fossil fuels. As the expiration date of these resources approaches, we must rely on finding alternative fuel sources. In this essay we will discuss both the problems associated with the use of fossil fuels and the solutions we have found. Say no to plagiarism.

They were formed through the carbon process called sedimentation (formed by decaying organisms) mainly 360-300 million years ago during the Carboniferous period. When combustion occurs (burning fossil fuels), the hydrocarbons in the fossil fuel create energy. The energy is then converted into electricity and used for all kinds of purposes. Fossil fuels are cheap and easy to export and import. According to the CIA, the world generates more than 66% of its electricity from fossil fuels. But according to the global carbon budget, it also generates 87% of the world's carbon dioxide emissions. Fossil fuels contribute enormously to damaging the environment. National Geographic refers to carbon budgeting, which balances carbon in water, land and air. It is stated that during the combustion process the carbon dioxide that has been stored in fossil fuels is released in the form of carbon dioxide. This has a negative impact on the earth by unbalancing the greenhouse effect. The greenhouse effect is a natural process of warming the earth. The sun sends solar radiation towards the earth, a part of the solar radiation is reflected into space by the earth's atmosphere, a part enters the earth's atmosphere. This is then absorbed by the land and oceans which heat the earth. They release radiation through heat and it heads out into space. The greenhouse gases present in the atmosphere are able to retain part of the heat contained in the Earth's atmosphere while a part is sent back into space. Recently, due to the massive use of fossil fuels and the greenhouse gases (carbon dioxide) they release, many more have increased. the heat is not released back into space. This is what we call global warming, which is causing climate change, animal extinction, plant extinction, etc. Fossil fuels are the cause of such problems affecting the earth and scientists must find alternatives. The alternative fuel I chose is biodiesel; a renewable and biodegradable fuel. It is a cleaner burning substitute made from vegetable oil, animal oil/fats, tallow and used cooking oil. Currently, most biodiesel is produced from waste vegetable oils from restaurants and food manufacturing companies like Birdseye. Biodiesel produces lower levels of most air pollutants than petroleum-based diesel fuel. To lower prices, a common blend of biodiesel is usually sold as a blend of biodiesel and petroleum-based diesel fuel, a common blend is B20 which contains 20% biodiesel. The use of alternative fuels and energy sources such as biodiesel in.
