I've been hearing about the new "green" cars that run on alternative fuels. Is it true that they're better for the environment?

It depends on what you mean by "better." If you mean that they are more environmentally friendly, then yes, they are. They produce fewer greenhouse gases and use less energy to operate than traditional gasoline vehicles. However, there are still some environmental impacts associated with producing these vehicles, so it is important to consider all of the factors before deciding which type of car to buy.
