How You can profit from Sustainable Transportation

As populations continue to rise, and the people of China, India and other developing countries gain affluence, fossil fuels will continue to rise in price. This creates both opportunity and danger. Countries that refuse to adopt sustainable methods of transportation will face more problems as current energy supplies deplete. The same can be said for individuals. People who act early and avoid the rising costs associated with transportation stand to profit from having cheaper, renewable options.

Current Transportation Costs

The Huffington Post reports that the average American spends over $2000 per year just to fill up their gas tank. The volatility of gas prices means that this expenditure fluctuates, but prices have been rising regularly for decades and will continue to do so. Forward thinking people can get ahead of others and begin using sustainable methods of transportation now and save time, money and effort.

Methods of Sustainable Transportation

The term sustainable transportation means any form of transport that has minimal impact on the environment. Some methods of sustainable transport have less environmental impact than others, but everything from walking to car pooling creates a more sustainable transportation system. Other methods include cycling, green vehicles and expanded public transportation. Continue reading “How You can profit from Sustainable Transportation”

Why Buses Are Starting to Convert to Electric Vehicles

One type of vehicle which has enjoyed a change for the better with the advent of new EV technologies is public buses. Gasoline-powered buses, in general, get very low gas mileage, due to their size and, in cities, their constant “start and stop” patterns of driving. By converting to EVs, these vehicles save tremendously in fuel consumption and dangerous emissions.

The first attempts at an EV bus met with little success, due to the immense amounts of power needed to run large buses. This situation continued until dual-battery systems were designed. In a dual-battery system, sodium halide batteries, which have the advantage of compact storage space, can be used to store relatively large amounts of power, while still delivering strong power at a high rate.

When combined with lithium-ion batteries, and a computer-managed regulation system, this configuration gives buses the energy needed to power larger vehicles without a sacrifice of reliability. In fact, GE, one of the pioneers of the dual-battery system, estimates that cost can be reduced by 20% or more over traditional single-type battery systems.

Other metallic combinations have also been used with success. At Heathrow Airport in London, a lithium-phosphate battery designed by Valence Technology of Austin, Texas, powers the British Airways employee bus. Designed by Optare, the 25-seat Solo EV is the first full-size all-electric bus in use at the airport. Continue reading “Why Buses Are Starting to Convert to Electric Vehicles”
