No two ways about it, "car" era of gas-oil. Within 2 decades ahead. Are expected to have cars on the road around the world more than 2000 million vehicles in the same time? Energy-saving cars and hybrid-power cars or "hybrid", it will be more widely used. New technologies that support mass transit systems that use electric power, it will have to develop extensively as well. However, in the majority of the power for another 5 years ahead, expect car-bus, will no longer have to rely on the use of energy from oil & gas anymore. Because future cars will be powered by a new type of "battery", which supports applications for several days or several months. Before charging again. Depending on your driving habits that often use. Now scientists are designing new kinds of batteries that make cars run up to 400-800 kilometers per charge one time increased from the current rush has just 80-160 km. Intelligent electricity transmission networks (Smart Grid), based on the large cities will help cars can charge up in public, and even the use of "alternative energy" can be reused, such as wind power to charge the battery without relying on power plants that use coal power anymore. This will give each city can reduce the amount of carbon emissions into the atmosphere, coupled with reduced noise pollution because of the electrical engine, very quiet.
