The transportation sector accounts for roughly 37 percent of the world’s carbon emission. The annual consumption of an estimated 57 TWh of fuel comes from fossil fuels that are utilized in combusted engines.
The innovative new electric engines are on less polluting than the combusted engines. They are more energy efficient and can support a widespread reduction in greenhouse emissions. The most common type of electric engines is hybrid systems. They use both combustion and electric engines. For example, “Toyota Prius” is a hybrid car model.
Vehicles that are “purely electric” are also coming out in the market. In Norway, January 2010, there were already 2700 electrical vehicles registered. These electric systems are based on battery storage of electrical power. A possible alternative to battery storage is hydrogen, which has the advantage of being able to store more energy in less space. Hydrogen is also a renewable source with no carbon dioxide emission. Nevertheless, hydrogen technology is still in an infant stage of development. This means that the technology is too expensive and not yet perfectly engineered.
In Norway, the industry of electric cars is slowly expanding. A company known as ElBil Norge creates cost-effective Kewet Buddy. It is now increasingly investing in hydrogen technologies. It is likely going to bring new electric car models to the market in the years to come.
