The range of cars that can run on renewable fuels is increasing. First, there are cars on ethanol (E85) and biogas can be used. There are also a number of cars and hybrid electric drive.
For those who are significantly reduced emissions of fossil carbon dioxide per kilometer.
Gasoline
Gasoline is still the preferred fuel in the world. Sales of 95-octane gasoline is 95 percent of oil and five percent ethanol. Ethanol stock is now at five per cent of the EU directive on fuel quality, limited, but the rules have changed. From January 2011 to increase this share to 10 percent.
Diesel
If you have a diesel car, fuel consumption and emissions of carbon dioxide by 20 percent compared to a gasoline engine the same size and engine power due to higher diesel fuel. The combustion of one liter of diesel to 2.48 kg of fossil carbon dioxide. Instead of considering the life cycle (such as air pollution caused by the refinery, marketing, etc.) 2.98 kg of fuel emissions. Compared to a gasoline engine and diesel cars slightly higher emissions, especially nitrogen oxides – acidifies the soil and water – and the particles that are harmful to the respiratory and cardiovascular systems.
Most new cars have diesel particulate filters (2005PM Environment), alleviates these problems.
Ethanol (E85)
E85 (15 percent ethanol mixed with gasoline, 25 percent in winter) is a fuel made primarily from renewable resources like sugarcane and corn. Ethanol has less energy content than gasoline. Consumption per million is about 35 percent higher than gasoline. From the perspective of the life cycle. The emission of carbon dioxide by 55 percent less than gasoline when you consider that the emission of fossil carbon dioxide in the production and sale of ethanol and gasoline.
Cars can run on E85 and flex-fuel cars because they can run on a mixture of gasoline and E85. Transport Agency estimates that the proportion of E85 ethanol vehicles in 2009, about 60 percent. With this level of E85 ethanol vehicles release carbon dioxide about 20 percent less fuel than the average new car. Emissions of other substances harmful to the environment and health is the same as gasoline cars.
The number of E85 stations is increasing rapidly across the country and beginning of September 2010 there were about 1700 pieces.
Vehicle
Fuel is composed primarily of methane. It is renewable (biogas from organic materials such as sewage sludge, manure and waste) and fossil fuels (natural gas).
Biogas pure, without significant emissions of fossil fuels, but small amounts of methane released into production. Although biogas vehicles, thus influencing the climate, but emissions from 80 to 90 percent less than gasoline. Natural gas reduces emissions of carbon dioxide as well as in comparison with diesel fuel accounted for approximately 20 percent. Emissions of other substances harmful to the environment and health is the same as gasoline cars.
Many models and run a shorter distance with a gasoline engine runs on gas. The fuel tank is small (15 liters), while other models have larger fuel tank, and you can run a greater distance than gasoline.
Hybrid electric cars
In hybrid vehicles combine a conventional internal combustion engine with one or more electric motors and a battery to store energy from the engine and brakes. Thus, fuel consumption is lower. Since the combustion engine stops automatically when you stop at a red light for example, not idle. Hybrid electric cars have their biggest advantage in dense city traffic, where the number of starts and stops are great, but also in the way of highway consumption is relatively low, because hybrid cars are usually equipped with relatively small internal combustion engines internal.
