Methods of Achieving Sustainability In this project suggests several ways to make the system more sustainable. (Variable speed appliance for energy saving included curtain pullers, trains themselves, automatic screen door, moving walkway, lift and escalator, compressors and pumps, catapults and launchers.) There are many discussed with respect to their "Efficiency of use and Conservation". These are defined as follows:
Conservation: Changing policy and/or processes of the MTR system so that it requires less energy to operate.
Efficiency of Use: Changing the nature of technologies within the MTR so that they require less energy to operate. While both these approaches are valid ways of increasing sustainability, it is important to tackle the problem of sustainability from numerous angles. It can be assumed that developments will be made to achieve both conservation and high

Energy has easily become one of the most important necessities for our everyday lives. Without it we would simply not be able to have transportation or be able to gather any of our other resources that we depend on. If at anytime our energy supply ceases or no longer attainable the results may be horrific. However, it is quite easy to keep this from happening, It is crucial that our current population realize the importance of sustaining our present non-renewable resources. An examination of all the present energy issues and human impacts of energy conservation along with the a resource plan will show importance of energy

Horizon Utilities Corporation is pleased to recognize the efforts of National Steel Car (the only producer of railroad cars in Canada) for saving an estimated 2,192,400 kWh per year . Horizon Utilities’ conservation and demand management teams worked with National Steel Car to assist in finding greater efficiencies. The company
Case Background: - In transportation industry, one of the biggest challenge is how to deal with carbon dioxide emissions and how to reduce the energy. According to the Natural Resources Canada, one third of the greenhouse emission is because of transportation industry.
I agree with Winona Ryder in the sense that Abigail Williams craved attention and led people to believe that witchcraft was present in Salem to gain power; however, I don’t think she was entirely innocent. Abigail essentially sparked the idea of witchcraft in her attempt to be with John Proctor, when she tried to get rid of Elizabeth Proctor. In Act I, Betty calls Abigail out, saying she drank a charm to kill John Proctor’s wife, to which Abigail threatens her. After being seen in the woods together, the girls are all accused of witchcraft, but they twist it around on others in the town. Abigail convinced all her friends to go along with this plan, even threatening to harm them if they speak against her. In Act III, when Mary Warren confessed
Three quarters of emissions in 2004 were coming from road traffic (Woodcock, p.1930, 2009). Emissions used from transportation are forecasted to increase from the year 2007-2030 by about 80% according to studies done by James Woodcock who is currently studying climate change and health from car fuels (Woodcock, p.1930, 2009). This is due to the fact that the emissions from vehicles are increasing significantly and are higher than any other energy fragment (Woodcock, p.1930, 2009). The only way to lower this percentage is to decrease the number of individual automobiles on the road and increase the number of public transit systems, starting long distance walking to work or school, carpooling or even biking to destinations. These principles would
Pursuant to energy efficiency policies, controversy swirls as climate changes are experienced in the U.S. and around the globe. When energy efficiency steps are put into place, economic outlooks turn positive. Obama’s policymaking in this arena makes “critical investments in advanced vehicle and fuel technologies, public transit, and high speed rail” (United Press International). With new fuel efficiency standards that will improve fuel economy by 2025, and other initiatives that he enacted, “12 billion barrels of oil will be saved and American consumers will save $1.7 trillion at the pump, and greenhouse gas emission standards for commercial trucks, vans, and buses for are projected to save over 500 million barrels of oil and save vehicle owners and operators an estimated $50 billion in fuel costs” (United Press
There are many potential pathways to decarbonisation, but one in particular covers all the important aspects. This pathway involves having ambitious energy efficiency, which leads to a
Town of Banff has a new “environmentally innovative public transit system”(www.ecovert.ca). The purpose of these busses are to increase ridership, to reduce greenhouse gas emissions and support Banff’s “Environmental Stewardship Policy—to nurture a sustainable community with a balanced approach to social and economic development”(www.ecovert.ca)
In order to live sustainably in a world with limited resources and increasing environmental, social and economic inequity it is vital for institutions, individuals and companies to examine the way
【介绍】Confucianism and Daoism are not only two of the most influential beliefs in ancient China, but also in contemporary society. They have played important roles in development of Chinese civilization. Both Confucius and Laozi were born in a chaotic period and their thoughts were originated in the late Warring States Period that there were wars among the subsidiary countries. In front of the dark society, they all produced rich thoughts of life. Confucius and Laozi had same moral thoughts of focusing on self-discipline and social progress.
