Global Energy Consumption On Fossil Fuels - 1856 Words

Today, global energy consumption heavily relies on fossil fuels, such as oil, coal and natural gas, in 2015, Australia relied 86% of the electricity generation on traditional non-renewable energy sources (73% coal, 13% natural gas).1 The burning of these fossil fuels has been very closely associated with carbon and greenhouse gas emission, resulting changes in the climate such as global warming and extreme weathers. The CO2 emissions had increased from estimated 198 megatons in 1850 to an astonishing 32274 megatons in 2011. The CO2 emission increased 160 times in just the last 160 years.2 As such, the exploration of new, clean renewable energy sources becomes increasing important. To meet the ever increasing demand for energy, renewable energy resources like solar, wind, geothermal, tidal wave and biomass have been introduced and successfully made up almost 22% of the global electricity generation in 2013, and the IEA predicted that this number is going to increase to at least 26% by 2020. †¢ Background Salinity Gradient Energy (SGE) uses the chemical potential difference between two solutions with different salinities. It has recently gained attention as a promising candidate for reducing the reliance on fossil fuels along with the completion of a prototype of the osmotic power plant in Norway, built by a renewable energy company Statkraft. A 2012 study from Yale university concluded that the highest extractable work in constant-pressure PRO (Pressure-Retarded Osmosis) withShow MoreRelatedGlobal Energy Consumption On Fossil Fuels1857 Words   |  8 PagesAbstract Today, global energy consumption heavily relies on fossil fuels, such as oil, coal and natural gas, in 2015, Australia relied 86% of the electricity generation on traditional non-renewable energy sources (73% coal, 13% natural gas).1 The burning of these fossil fuels has been very closely associated with carbon and greenhouse gas emission, resulting changes in the climate such as global warming and extreme weathers.

Each stage in the evolution of human society (the development of farming, domestication of animals, harnessing of wind and water power) increased the average per capita energy use, but it was the Industrial Revolution and theRead MoreFossil Fuel Subsidy Reform :1504 Words   |  7 PagesFOSSIL-FUEL SUBSIDY REFORM Intro The US spent 699 billion dollars to subsidize the fossil-fuel sector in 2015. The removal of fossil-fuel subsidy will enormously benefit energy markets, strengthen climate change policy and government budgets. Not only do fossil-fuel subsidies undermine global efforts to mitigate climate change, but they also aggravate local pollution problems, causing further damage to human health and the environment. They represent a considerable strain on public budgets asRead MoreA Formula for Using Alternative Energy to Reduce Global Oil Dependency1579 Words   |  6 Pagestrade arrangements which contribute to global disharmony. The continued use of oil in its many applications is a dominant cause of air and water pollution, which is substantially contributing to global warming. Only by reducing mankinds dependence on oil can these issues be constructively addressed. Alternative forms of energy are the rational solution for reducing global oil dependency, which will result in positive changes to the global environment and to global political affairs. Oil reservesRead More Renewable Energy Essays1296 Words   |  6 PagesThe most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gasRead MoreEssay on The Threat of Global Warming1667 Words   |  7 PagesThe Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad.   Ã‚  Ã‚  Ã‚  Ã‚  By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human historyRead MoreGlobal Warming1677 Words   |  7 PagesThrough the eyes of most scientists, global warming is seen as a very serious and severe threat.

Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. In nuclearRead MoreUnited States Energy Crisis During 1970 Essay examples1271 Words   |  6 PagesThe energy crisis of the 1970’s caused authorities to search out other renewable sources of energy, which currently remain undeveloped and keep the U.S. today generally dependant on foreign fuel. According to Merriam Webster dictionary, a crisis is a â€Å"difficult or dangerous situation that needs serious attention.† The energy crisis of the 1970’s produced a backlash that affected much of the economy and spread fear and panic over the United States. Energy Crisis (1970’s) states that the crisis officiallyRead MoreHow Can The United States Lessen Its Dependence On Fossil Fuels?1302 Words   |  6 PagesHow can the United States lessen its dependence on fossil fuels? Joan Milton Western Governor’s University How can the United States lessen its dependence on fossil fuels? Introduction The U.S obtains more than 84% of its energy from fossil fuels including oil, coal and natural gas. This is because people rely on it to heat their homes, power industries, run vehicles, manufacturing, and provision of electricity. It is apparent that the country’s transportation industry highly depends on
