Eco-Friendly cars

What make these cars eco-friendly? Why are they called such?
They reduce greenhouse effect, polluting of rivers and air . If such cars are used then no one will have asthama or any other disease due to polluted air. China has announced that it will give US$ 15 billion to initiate industry within its borders. But solar cars are much better. But are they not yet launched.

These cars were popular in the late 19's and the early 20's until advances in internal combustion engine technology and mass production of cheaper gasoline vehicles led to decline in the use electric drive vehicles. The most important thing is that they are environment friendly and burning of fuels does not take place so no air pollution. There adoptions has several hurdles and limitations. There are more expensive than cars that drive on fuels due to additional cost of their lithium-ion battery pack .
