I am researching these topics because it has a lot in common. Fuel energy and technology is a very interesting topic, they are the most useful things by human being, it is used for important things and this will help me know more about the history of fuel and technology, I am a person that likes a lot technology because is different of other things. Without technology, fossil fuels cannot be extracted in an easier way because technology gives details of ground and how fuels companies can extract petroleum from the earth. Fossil fuels provides 66% of the world electrical power and 95% of the world energy demand and we need to have in count that fuel energy and technology is our principal source of transportation.

Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to modern society as we know it. Over 85% of our energy demands are met by the combustion of fossil fuels. Fuel is one of the most used earth product because in the entire world fuel energy is used to make a lot of important things such as vehicles gas, cells, etc. Fuel is any material that can be used to generate energy to produce mechanical work in a controlled manner and the processes used to convert fuel into energy include chemical reactions, such as combustion, and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as metabolism. Hydrocarbons are by far the most common source of fuel in current use, but many other substances can be used as well. The most interesting case about fuel energy is how it was create or how human being in the past thousand years has the incredible idea to perform energy source, fuel energy was first starts with wood. It was one of the first fuels used by humans and is still the primary energy source in much of the world. These discover was performed by home erectus near 2 million years ago. A very important thing to say is that without fuel, our technology never will be developed because without that, cars, airplanes and all types of vehicles will not work.
Fossil fuels exist long before dinosaurs roamed the Earth. These are made up of plant and animal matter. When plants and animals died, their bodies decomposed and were buried under layers of earth. Millions of years later we have the three forms of fossil fuel: Oil, Natural gas and Coal. The advantages of fossil fuels is that they produces a lot of electricity especially coal, its cheap, transporting coal and gas is easy and power station that run on gas are very efficient and the disadvantages is that burning fossil fuels produces carbon dioxide which result in greenhouse gases that mean global warning alert, burning coal produce more carbon dioxide than gas and oil and it also produces sulphur dioxide that causes acid rain. According to scientists burning fossil fuels produces 20 billion of carbon dioxide every year and the earth natural process can only absorbs 20 billion tons of carbon dioxide and the remaining carbon dioxide goes to the atmosphere and contributes to global warning. The oil is found way down in the ground, usually between layers of rock. To get oil out, a well is dug. Digging a well is like putting a straw into a can of pop. The oil is then pumped out of the ground, just like when you suck pop up the straw. Oil is carried in pipelines and large tanker ships. A refinery changes the oil into products like gasoline, jet fuel and diesel fuel. It’s also burned in factories and power plants to make electricity Natural gas is made out of methane, which is a simple chemical compound made up of carbon and hydrogen atoms and this gas is highly flammable. Natural gas is found near oil in the ground. It’s pumped, just like oil, from wells that tap into the source and send it to large pipelines. Because you can’t smell or see natural gas, it is mixed with a chemical to give it a stinky smell like rotten eggs. For thousands of years man has depended on fossil fuels as his primary energy source.
Chapter 3ƒ Technology
Technology is the process by which humans modify nature to meet their needs and wants. Technology means computers and software, aircraft, pesticides, plasma TVs, birth-control pills, and microwave ovens, to name a few. But technology is more than these tangible products. Human being has found the correct way to make life easier and effective. Technology is what the world needs to develop in the faster and easier way, with technology everything can become possible and everyday technology is growing up. The use of the term technology has changed significantly over the last 200 years. Before the 20th century, the term was uncommon in English, and usually referred to the description or study of the useful arts. Technology is meant to be our future of our life. Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. With technology this world will have a better future and we will have a better lifestyle with a healthy and long life because technology is what is changing this world. It is true that technology is also bringing a lot of problems for today’s young society because they are getting in their own world using internet, PlayStation etc…this is making childhood to be dependent of themselves and they don’t do activities like sports going out with friends or interacting with family so this is the mayor problem of technology, people are getting addicted of excessive uses of technology because is more easier so they get lazy. It is the current state of humanity’s knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfies wants. It includes technical methods, skills, processes, techniques, tools and raw materials.
In the world exist a lot of problems about global warming and this is happening because fuel energy extract, but we can be intelligent and take care of our planet and contributes in saving water, don’t destroying our habitat, the world is created for us to live and is our home so it is incredible how humanity is destroying the world without thinking of a world destruction or humanity destruction. Fuel energy and technology is of great importance in the entire world because without this our advanced things like computers, motor vehicles, electronic devices, internet our world will not work as efficient as it is working todays days, everything is easier than the last 100 years. These two resources give a great contribution to the world. Technology gives a better way of communication and fuel a better way of transportation.
