Which alternative fuel?

It is quite well understood that electric cars have the potential to reduce carbon emissions, but it is important to recognize that this potential depends on the type of electricity the battery is charging. Power generation creates a large footprint in our environment, bringing electric vehicles into a less green area. And we must also take the emissions from vehicle production into account in the calculation. When electricity is generated from coils or natural gas, the CO2 emissions of an electric car are higher than those of a car with a combustion engine. It can take decades for most electricity to be generated without burning fossil fuels.For all comparisons with CO2 emissions in production, the vehicle construction of a petrol car is only 40g CO2e/km compared to 70g CO2e/km for an electric vehicle. This is due to the fact that we have achieved both a larger production area and a shorter service life in an electric car.

As a result fuel consumption is lowering through development of new engines. New direct injection engines are being competitive with electric cars in CO2 footprint in most EU countries, and with the use of liquefied petroleum gas LPG they would become greenest, cleanest vehicles on the market. Problem is that technology which enables us to use LPG in new engines is not developing simultaneously in comparison to the development of engines. The development starts later, when the new engines are already on the market.
