1. Introduction :
We are facing grave dangers due to the depletion of fossil fuels, and hence we are trying to look for alternate sources of energy.
After doing a brief study of major forms of energy both renewable and non renewable- namely solar energy, tidal energy, wind energy, geothermal energy, biomass energy, biofuels, hydrogen energy, fossil fuels etc I realised that fossil fuels i.e coal, oil and natural gas will be meeting our major energy requirements for the next 50 years or so. And hence we need to optimise the oil we get from a reservoir to the maximum for which we use
Now we mostly use fossil fuels and natural gas to produce energy. But these sources are running out. To save our planet we should use a new class of renewable energy sources, like wind turbines, solar panels, biofuels and hydrogen. Because our need for power is constantly increasing in the future we will have to produce more energy, which is associated, among other things, with greater emissions of CO2 and further pollution of the environment and global warming. Most likely oil is going to be the first one that’s not going to be sufficient enough to satisfy our needs in the future. To transition to alternative sources of energy would require a rapid expansion of those sources. Now alternative sources of energy playing a small percent of the world’s energy. To transition we would have to triple or quadruple that percentage.
Throughout the entire modern age, mankind has used fossil fuels to meet its energy requirements. Coal, oil and natural gas have lit homes and powered machinery for centuries, driving civilization forward. But as human
Accounting for most of the world’s source of energy is fossil fuels. These sources are
Fossil fuels are cheap and easy to come by right now. Oil rich countries in the middle east are able to import 9.4 million barrels of petroleum into the U.S. each day for use. For these reasons, Americans may see no need to switch over to a new energy source. However, the burning of fossil fuels produce gases that trap heat inside the Earth’s atmosphere, which cause the global temperature to rise, or Global Warming. Ocean levels are rising and storms such as
Over many decades oil has supplied the global market with a realatively inexpensive method to provide energy and countless products. Without oil the world would not be as well developed as it is today. Large countries such as the USA and China thrive off oil and without it would come to abrubt halt. [1]
The world is not coming up short on oil itself, yet rather its capacity to deliver top-
It is estimated that 50-60 percent of the oil remains in the Gulf, after the use of methods such as burning and chemical dispersion. This event had some serious consequences on our marine environment, including 4,768 dead animals washed up on shore.1 These horrifying numbers have sparked interest in alternative methods for
Despite the positive development of oil and gas industry in this last decade, there is something more valuable have been put on the line. The environment needs to pay for every single mistake made by the human. One of the greatest mistakes in humankind history is an oceanic oil spill. It has become a major environmental problem that the world is facing right now. History has shown how this problem could go. From the first major commercial spill of 1967 in the United Kingdom, up to the most recent one, at BP Deepwater Horizon Oil Rig, that leaked thousands barrel of oil into the Gulf of Mexico since April 2010. Most large-scale oil spills have been disastrous and the marine wildlife is still recovering. Hence, the tension for a better cleanup technology increases.
Because the supply of fossil fuels is quickly running out, scientists are searching for alternative fuel
Coal, coal is our most used resource in the world. It’s dependable but far harder to obtain than you think. We’ll be seeing what, when, where, how and why we use coal. For centuries, humans have had a close bond with coal, fires centuries ago to fuelling technology today. The use of coal is scarce though, meaning it’s a non-reusable resource not only is it unsustainable it prove to be detrimental to the environment. Due to this fact, we cannot use coal in large amounts as there ill be many negative effects.
It is my profound privilege and pleasure to express the over whelming sense of gratitude , devotion and regards to my project guide "Dr. Dolly Sharma"
Through out the history of the United states the main source of energy has been conventional Oil, Coal, and gas energy, or better known as Conventional petroleum energy. However as the demand for electricity sky rockets the pollution produced from the traditional fossil fuel burning plants is reaching dangerous levels. Gas, coal and oil burning power plants are as of now responsible for half of America’s air pollution (tripod/online). Not to mention fossil fuels are the greatest contributors to global warming in today’s society.
[Fossil fuels are expected to continue supplying much of the energy used worldwide. Although liquid fuels—mostly petroleum-based—remain the largest source of energy, the liquids share of world marketed energy consumption falls from 34 percent in 2010 to 28 percent in 2040, as projected high world oil prices lead many energy users to switch away from liquid fuels when feasible. http://www.eia.gov/forecasts/ieo/more_highlights.cfm]
Most people today use fossil fuels, but there is a problem that comes with using them. Soon, the world is going to run out of fossil fuels. The average person uses some type of fossil fuel every single day, and cannot imagine a world without them. Can you imagine a world with no gas, propane, or coal? Better yet, can you imagine the world without the machines, vehicles, and appliances that are powered by fossil fuels. Fossil fuel is not the only form of energy, though. There is also alternative energy. We must start using alternative energy. We must start using alternative energy, or we will deplete our fossil fuels.
I also offer my thanks to honorable Rector Prof. Ch. Abdul Rehman for providing me a chance to work on thesis.
