Yes, infact vehicles are considered to be the main contributor to the Co2 in the atmosphere
Yes, they are still using fossil fuel as the energy supply
They run on more miles for one gallon, needs less resources!the emit less Co2 and other harmful gases
This depends upon how the electricity is generated. Electric cars powered by electricity from coal fired power plants reduce local CO2 emissions, but increase them overall. Cars powered by wind, solar, nuclear, or hydrological power emit very little CO2.
Animals emit CO2 when they exhale.
It absorbs Co2 through the process of Photosythisis.
No. Plants emit their own CO2 through respiration.
Hardly any at all ... hard to believe from what we perceive as exhaust emitting from their tall pipes, but some semi trucks emit less emissions than some older passenger cars.
1% of the worldds emissions
Once a flower is cut and starts dying it does emit CO2 as it decomposes.
The impact hybrid and electric cars will have on our environment is a very negative one. Just because they emit no or less Co2 doesn't make them good for the environment. Ask yourself, what is more harmful, emitting Co2 (Plant food) or using rare unsustainable minerals and metals for use in batteries? Not to mention you can use Co2 to grow plants for the use of food or biofuels.
Yes they do.
Too much !
