Scientists predict that in the next five years, there will be hundreds of thousands of hybrid trucks and buses on the road. Hybrid means these heavy-duty trucks and buses will be smaller, but much more fuel-efficient, reducing the emission of greenhouse gases. The global market for hybrid trucks and buses in 2010 is 9,000 vehicles. This number is expected to increase to 100,000 vehicles in 2015, which means there would be a 63% increase per year, with a total of 300,000 vehicles sold within the 5-year period. Navistar, Freightliner and other mainstream truck brands will start to offer hybrid trucks that run only on electric power. Hybrid sales have dropped since 2007 due to recession, but fuel prices is expected to increase the sales. The biggest problem to getting hybrid trucks and buses right now is the high costs, but in the U.S., there are federal tax incentives and states vouchers to help lower the costs.
This article relates to science concepts, because there will be new hybrid trucks and buses coming out. This means better vehicles, and much better improvements for the world as well, since hybrid means saving more fuel and releasing less greenhouse gases into the atmosphere.
We should care about this matter, because hybrid trucks and buses benefit us greatly, and also because we live within the atmosphere of this planet. When greenhouse gases are released from regular trucks into the atmosphere, it doesn't benefit the Earth and doesn't benefit us at all either. We benefit from these heavy-duty trucks and buses since they are operated for the service of the people and cities.
