The greatest way in which technology has helped in reducing CO2 emissions is through the electric cars. Electric cars have the potential to reduce carbon emissions, local air pollution and reliance on imported oil.
Although there is widespread understanding that electric cars can reduce carbon emissions, depending on the electricity they use can show us how effective they can be.
Even though people from all over the world can benefit from these electric cars, their carbon emissions are four times greater in places with coal dominated electricity than in countries with low carbon power.Where power generation is coal dominated electric cars are the emissions equivalent of average petrol cars, while in countries with low carbon power they result in less than half the emissions of the best petrol hybrids.
At the moment, Toyota and Honda are the greatest automobile manufacturers that have expanded the use of electricity.
