Oil spills have devastated ecosystems and coal mining has stripped lands of their vitality. Nitrogen dioxide NO2 emissions from transportation sources reduces lung function, affect the respiratory immune defense system and increases the risk of respiratory problems.
In fact electricity is just as effective for propelling vehicles as gasoline is. The shortage of oil would be more manifest in coming times as oil demands are growing world wide, especially in China and India with rapidly expanding economy, transportation system and consequently requirement of petroleum oil.
It is thus difficult to evaluate and to appraise the specific contribution of transportation over various environmental issues, which explains that problems tend to be addressed on a modal basis. But fortunately the world has the capacity to read these signals and develop reliable intermediate technologies and systems such as hybrid electric vehicle, ethanol and public transit systems that would considerably reduce fossil fuel consumption without adding to infrastructure cost thereby extending the life period of petroleum reservoirs.
This is particularly complex as most environmental relationships tend to be indirect and cumulative. It could also create jobs in manufacturing, installation, and maintaining these new energy resources.
The structure of the transport network, the modes used and traffic levels are the main factors of environmental impact of transportation. But fortunately the world has the capacity to read these signals and develop reliable intermediate technologies and systems such as hybrid electric vehicle, ethanol and public transit systems that would considerably reduce fossil fuel consumption without adding to infrastructure cost thereby extending the life period of petroleum reservoirs.
The goal is to use advanced traffic technology and centralized traffic management to reduce urban road congestion through widespread application of wireless or dedicated radio roadway sensors and vehicle transponders. Although carbon dioxide is non-toxic and is a byproduct of efficient and complete fuel burning, there are international and US efforts to limit its production rate and accumulation in the atmosphere.
Historically, transportation was associated with a few negative environmental impacts. Reductions in the relative importance of one type of externality redirect the focus on other types that were less addressed, but probably as important in the overall impacts of transport over the environment.
Sometimes, public stakes in transport modes, terminals and infrastructure can be at odd with environmental issues. But until our renewable energy sources become more viable as major energy providers, the only alternative for our global population is for these companies to continue tapping into the fossil fuel reserves to meet our energy needs.
The fact is that neither one of these projections is very appealing for a global community that is so heavily dependent on fossil fuels to meet basic human needs. These concerns have already spawned intense research in alternative technologies to meet the future energy needs in the face of an impending petroleum crisis.
Natural gas currently plays an essential role in home use and in electric power generation. Hydro electrical or wave and tidal power could have a huge impact when it comes to supplementing or replacing currently highly used fossil fuels such as coal and petroleum based fuel sources.
Other greenhouse gases of concern include chlorofluorocarbons, including freon used for airconditioning in cars, methane, ozone and nitrous oxide.
This is the only Honda FCV being driven by any non industry citizen in the country. Both rail and waterborne freight are projected to increase at modest annual rates 1. It is however only in the 20th century that a comprehensive perspective about the links between transportation and the environment emerged, particularly with the massive diffusion of transportation modes such as the automobile and the airplane.
Research efforts and technology deployment are necessary, but not sufficient, since transportation and related energy consumption are tightly coupled to the economy and to the quality of work and life in our society.
Even if an administrative division municipality, county, state has adequate environmental enforcement policies, the geographical scale of an environmental impact notably air pollutants goes beyond established jurisdictions. Many noise regulations impose mitigation if noise reach a defined level, such as sound walls and other soundproofing techniques.
Fuel economy standards for automobiles, set by the Department of Transportation pursuant to the Energy Policy and Conservation Act, also impact the amount of CO2 emitted by vehicles.For many decades, fossil fuels have always been considered a reliable and well-developed source of energy; they had offered the world the possibility to evolve in terms of transportation, industry and technology.
Fossil Fuels and Alternative Energy; Fossil Fuels and Alternative Energy Essay Sample. Using the textbooks, the University Library, or other resources, answeranswers each of the following questions in to words.
Most types of fossil fuel are used in Cars, Industry in form of Petroleum and its product. Wood, Coal is used to.
Alternative Fuels Essay 8 Alternative Fuels This day in age, one of the world's main concerns is energy. Currently, we rely on petroleum to run our cars, and household central heat, and electricity in our homes.
Ethanol as a Transportation Fuel Essay. A+. Pages:6 Words This is just a sample. In this paper I will explore the use of ethanol as an alternative fuel source. A huge amount of land would have to be cleared, for crop production, to make a significant impact on the amount of fossil fuels that we currently use.
This could have a. - Alternative Renewable Energy “Windmills” Renewable energy is an alternative to fossil fuels and nuclear power, and was commonly called alternative energy in the s and s.
Scientists have advanced a plan to power % of the world's energy with wind, hydroelectric, and solar power by the year Alternative Energy is the Solution to the Fossil Fuel Dilemma If the United States continues to employ fossil fuels for energy, the nation will ultimately become more dependent upon fuel imports from the troublesome nations of the Middle East, and we will continue to damage our precious environment.Download
