Alternative Sources of Energy Essay

will collapse. The sources of the unconventional oil are tight deposits, oil shales, oil sands, and coal liquefaction. At current oil extraction rates, the peak oil extraction rate will be reached.…

planet. This reality creates a slow and steady increase in the earth 's temperature. It affects our everyday life and while many in our society have acknowledged that and attempt to restore the destruction by going "green," there are plenty of alternatives to pollution creating toxins that harm the ozone layer. This ozone layer is destructed by the buildup of atmospheric carbon dioxide and greenhouse gases, which in turn causes global warming. These gases are meant to trap the earth 's heat,…

commercial organic waste and agricultural waste materials and energy crops”. By the process of fermentation in these waste materials, the cleaner form of energy biogas is produced, which can be used for cooking purposes and as a fuel for vehicles that use natural gas. Another step to sustainability is converting from the large scale use of crude oil and coal to natural gas which is a cleaner source of energy, that produce equal amounts of energy to crude oil and coal but with much less CO2…

Onyx: The Practical and Metaphysical Story Onyx is a specific variety of the mineral known as chalcedony. It is a banded mineral, which means that the layering of the rock that formed it has caused “bands” of different colors to appear. Many people mistake onyx for a type of agate, which is another type of chalcedony, but where agate has curved bands onyx has parallel bands instead. Onyx is found in nearly every color, though bands of black and white are the most common. When onyx is banded…

Industrialization occurs when a country transforms from an agricultural society to a society centered on materialism and manufacturing. While industrialization led to economic growth, a booming population and an interconnected world, it also led to environmental damage. When countries become industrialized, they produce more products, and consume more resources. Ultimately, this leads to resource depletion, which causes deforestation and increased carbon dioxide emissions into the atmosphere.…

the use of nuclear energy continue?” Fukushima and many other critical junctures since the start of the first nuclear reactor in Idaho, in December 1951, have influenced changing attitudes towards nuclear energy throughout time. Nuclear power is one of the primary sources of energy, it provided over 19% of the total electrical output in the United States alone. (World nuclear association). While at some points of history the world seemed to favor the existence of nuclear energy, the constant…

These steps are essential and the product produced is in powdered form (Abdelwahed et al, 2006). Air drying is the ancient process of preserving food, it is done by exposure to steam to evaporate moisture. Its only disadvantage is that the mass and energy transport is in a hygroscopic system, thus shrinking the product. The process of lyophilization is then introduced wherein there is no shrinking of the actual product but the removal of water from the system. It is commonly used in culture…

Biodiesel is an alternative diesel fuel for diesel engines that is made from renewable biological sources like vegetable oils, animal fats, and microalgae. Since its main feedstock is a vegetable oil or animal fat, biodiesel is generally considered to be renewable. There are four primary ways known to make biodiesel – (1) direct use and blending, (2) microemulsions, (3) thermal cracking and (4) transesterification. Although the main use is the transesterification of vegetable oils and animal…

their strength and weakness Natural Gas Fuel (- NONRENEWABLE) 1. Propane – Uses LPG 2. CNG – Burns methane Propane engines last twice as long as conventional engines – lower maintenance. Range is 25% less than gasoline cars because of the lower energy content of fuel Performance is similar to a gasoline-powered car Natural gas fuels emit 1/3rd fewer reactive organic gases. HYDROGEN FUEL Hydrogen internal combustion engine (HFCE) produces nitrous oxides. Hydrogen fuel cell vehicle…

Gazprom is a leading energy company which is focused on all stages of gas exploration, production and processing. Another area of focus is sales of oil, gas and gas condensate; sales of gas as a vehicle fuel, as well as generation and marketing of heat and electric power. Gazprom’s primary goal is to ensure an efficient, reliable and balanced supply of natural gas, other energy resources and their derivatives to consumers. Gazprom is among Russia’s…
