Hybrid-cars or fuel cells: are they really necessary
Introduction The world’s energy requirement has seen extraordinary change in the last century. The advancement in transport technology and fast industrialization has made automobiles as the most important unit for economic growth. The use of vehicles as a mode of private transport, public transport and goods transport has caused alarming increase in the rate of consumption of fossil fuels like petrol, diesel and natural gas. Between the period 1999 and 2020, World energy consumption is projected to rise by 59 percent reaching 607 quadrillion British thermal units (BTUS).
But the point of concern is not this increase in demand. It’s the world’s dependence on fossil fuel which is the point of concern. These sources of energy are nonrenewable energy sources and at the same time cause great environmental problems. The Green House effect has caused major change in the world’s climatic pattern. The Kyoto Protocol agreement made under the United Nations Framework Convention on Climate Change (UNFCCC), countries that ratify this protocol should commit to reduce their emissions of carbon dioxide and five other greenhouse gases (Boardman, Darby, Killip, Hinnells, Jardine, Palmer, & Sinden, 2005).
Its not only the environmental effects that has made us think about alternative energy sources but also the economic one. The Oil price is now at around $65-75 per barrel from the figure of $10 per barrel in 2000 and if this trend continues the figure will one day cross all limits and may affect the world so hard that a very long period of recession will the economy.
