Why is it helpful?
Do I save?
Yes, of course you would save! Instead of buying a brand new car, that runs on gasoline, buy a hybrid, instead of gas you could use battery. Like its name it can use 2 things. Gas or electricity.
Do I help someone/something when I buy a hybrid?
Yes, you helpthe earth. All the carbon dioxiode on the planet is causing global warming we want to slow this down. The less waste we create the longer it will take global warming to warm over our planet!
