Green Transportation

An Introduction

A well-functioning and efficient transport sector is a requirement for economic and social development, bringing people together and enabling the trade and exchange of goods and ideas. However, the transport sector is also responsible for a number of negative social and environmental effects, including a significant contribution to global greenhouse gas emissions and air pollution. A global shift to a greener, low carbon economy will require significant improvement in the ways in which energy is produced and used. The transport sector uses over a quarter of the world’s energy and is responsible for a comparable share of global CO2 emissions from fossil fuel combustion. This will require both systemic and more specific technological solutions, such as: smart growth urban planning for fewer motorized trips, increased modal share of non-motorized and public transport, shifting incentives to more efficient and less polluting modes and technologies, and taking advantage of best available and most fuel and energy efficient technologies.

Electric Vehicles

Electric cars were prevalent in early 20th century, when electricity was preferred in automobile propulsion. Advances in internal combustion technology, especially the electric starter, the greater range of gasoline cars, quicker refueling times, and growing petroleum infrastructure, along with the mass production of gasoline vehicles reduced prices of gasoline cars to less than half that of equivalent electric cars, which led to the decline of electric propulsion. The energy crisis of 1970s and 1980s brought a renewed interest in electric vehicles. Further the global economic recession of late 2000s called to abandon the fuel inefficient SUVs, in favor of small cars, hybrid cars and electric cars.Read more

Bio fuels Vehicles

Biofuels have been around as long as cars have. But discoveries of huge petroleum deposits kept gasoline and diesel cheap for decades, and biofuels were largely forgotten. However, with the recent rise in oil prices, along with growing concern about global warming caused by carbon dioxide emissions, biofuels have been regaining popularity. Gasoline and diesel are actually ancient biofuels. But they are known as fossil fuels because they are made from decomposed plants and animals that have been buried in the ground for millions of years. Biofuels are similar, except that they're made from plants grown today.Read more

Bio-CNG Vehicles

Natural gas vehicles (NGVs) are good for our economy and our environment. Natural gas, like all vehicle fuels, can be used safely if properly handled. Natural gas actually has safety advantages compared to gasoline and diesel, because it is non-toxic, and will not cause contamination in the event of a release. With a very limited range of flammability, natural gas does not burn in concentrations below about 5 percent or above about 15 percent when mixed with air.Read more
