Contributors To Global Warming And Pollution

Pollution from cars and trucks is finally receiving attention from the public as global warming is discussed more openly and frequently. The transportation sector is the largest single source of air pollution in the United States today. It causes almost 67 percent of the carbon monoxide (CO), a third of the nitrogen oxides (NOx), and a fourth of the hydrocarbons in the atmosphere. Cars and trucks pollute the air during manufacturing, oil refining and distribution, refueling, and, most of all,...

Electricity Generation

Electricity can be generated for on-site use or for sale to a power grid. Different technologies can be used to generate the electricity, including internal combustion engines, turbines, microturbines, stirling engines (external combustion engines), organic Rankine cycle engines, and fuel cells.

Energy Sourcesfossil Fuels

Fossil fuels are hydrocarbons, derived from coal and petroleum (fuel oil or natural gas). They are formed from the fossilized remains of buried plants and animals that have been subjected to the heat and pressure in the Earth's crust over hundreds of millions of years. Fossil fuels also include substances like oil shale and tar sands, which contain hydrocarbons that are not derived solely from biological sources. These are referred to as mineral fuels. Today, most of the developed world's...

Energy Fossil Fuels and Global Warming

Global warming is the most urgent environmental challenge of the 21st century. Because of the world's continued dependence on fossil fuels as an energy source, greenhouse gas levels are steadily increasing in the atmosphere and warming the Earth. If corrective action is not taken now, temperatures will continue to rise, causing the worldwide destruction of ecosystems and extinction of species. The biggest contributor to warming the atmosphere is the excessive use of fossil fuels for energy. If...

Biofuels And Clean Vehicles

It is well understood that one of the biggest contributors to global warming is the burning of fossil fuels and that the United States is one of the largest contributors to the problem. Transportation-related emissions are responsible for 40 percent of the U.S. total global warming pollution. Because of this large contribution, this is one area where people can make a significant difference. One way is by conserving and driving less, combining multiple errands into one trip, and by using new...

Biodiesel

Biodiesel is a renewable alternative fuel that is made from soybeans, biomass, vegetable oil, animal fats, and recycled restaurant greases. Biodiesel can be used in its pure state (B100) or it can be blended with petroleum diesel. B2 is 2 percent biodiesel there is also B5 and B20 blend. The liquid fuel is comprised of fatty acid methyl esters (FAME) or long-chain alkyl esters. Biodiesel is produced from renewable sources such as new and used vegetable oils and animals fats. It is also a much...

Methanol

Methanol, also known as wood alcohol, is considered an alternative fuel under the Energy Policy Act of 1992. Currently, most of the methanol production is accomplished through a process that uses natural gas as a feedstock. Methanol can be used to make methyl tertiary-butyl ether (MTBE), an oxygenate that is blended with gasoline to enhance octane and create cleaner burning fuel. MTBE production and use has declined in recent years, however, because it was responsible for some ground-water...

Fossil Fuels And Global Warming

Oil and coal are commonly referred to as fossil fuels. The burning of fossil fuels is one of the leading contributors to global warming. Fossil fuels are made up almost entirely of carbon. In the case of oil, there are other toxic materials that when burned, or when the fumes are inhaled, are known to cause cancer in humans. When coal is burned to generate electricity or oil is burned in the form of gasoline or diesel fuel for transportation, carbon is released into the atmosphere in the form...

Cogeneration and Alternate Fuels

Cogeneration uses LFG to generate both electricity and thermal energy, usually in the form of steam or hot water. The production of alternative fuels is still in the early stages of development. According to the EPA, landfill gas has been successfully delivered to the natural gas pipeline system as both a high-Btu and medium-Btu fuel. It has also been converted to vehicle fuel as compressed natural gas (CNG) and liquefied natural gas (LNG). Projects to convert LFG to methanol are in the...

Emissions And OiL il Quick Facts

According to the Electric Drive Transportation Association EDTA , the following facts about oil, emissions, and the environment were gathered from leading authorities worldwide The United States' demand for oil is projected to increase by nearly 50 percent by 2025 Hydrogen Posture Plan, U.S. DOE, February 2004 . The clean commute program in New York, in which commuters drove electric vehicles to public charging outlets in rail stations, saved 6,664 gallons of fuel in one year NK clean commute...

Evolution since the Industrial Revolution

Civilization has progressed tremendously since the industrial revolution began in the mid-18th century. Until that time, society was largely agrarian, but as discoveries were made, inventions developed, and various industries started, people flocked to cities where the jobs were. This marked not only a turning point in human history, but in environmental history as well. The anthropogenic influence on the Earth's natural greenhouse effect began in earnest at this time. People's lifestyles were...

Biobutanol

Biobutanol is a 4-carbon alcohol butyl alcohol , produced from biomass feedstock. Its primary use today is as an industrial solvent in products like enamels and lacquers. Similar to ethanol, biobutanol is a liquid alcohol fuel that can be used in today's gasoline-powered internal combustion engines. Its chemical properties make it a good fuel to blend with gasoline. It is also compatible with ethanol blending and can improve the blending of ethanol with gasoline. The energy content of...
