Electric and Gas Cars
The popularity of such cars is rising mainly due to the increase in petroleum prices, as hybrid cars can consume a lot less fuel, or get a much better miles per gallon of fuel out of the car in other words. In fact, you can check out how much better mileage these cars get from the EPA (Environmental Protection Agency) website that aims to promote environmentally friendly driving habits at fueleconomy.gov/feg/hybrid_sbs.shtml The increase in petroleum prices is further made more apparent as the heavy taxes on car fuel make the problems more profound, particularly in places such as most of Europe. Also, due to worsening climate change / greenhouse gas emissions, the resulting tightening of environmental laws hurts the demand for traditional gasoline cars, particularly in environmentally progressive places such as California. Also, alternative fuel and power systems for vehicles is one of the most financed areas of research and development by both private capital sources and governments around the world. The combinations that use gasoline and electric engines on same vehicle are the most popular combination of two power sources, but by no means the only alternatives. These other forms of powering vehicles include fuel cells, compressed air, and natural gas, either as a standalone engine, or as a hybrid model with gasoline engine.
