The way you drive has a major play in fuel economy.. ! If you push through the gears, always want to be doing the speed limit where ever you are going, overtake everything you consider too slow... you use a LOT more fuel than if you ease along, are happy to give a nice big space between you and the car in front to avoid speeding up and braking all the time, are happy to do 60mph when the limit is 70 etc...
I'm not saying you should drive as slow as possible, keeping to the minimum revs you can get away with, rolling down hills, making sure you have the smallest amounts of water in the spray bottle, only wearing a thing t-shirt and shorts while in the car, cutting your hair short and shaving body hair to reduce weight etc.. but gentle smooth driving can save you hundreds of pounds in fuel, not to mention brake pads and tires etc per year..

ps .. even if you got a car that had enviromentally safe batteries... what are you plugging it into ?.. the mains?.. and how is that electrickery produced?..burning fossil fuels?.. splitting the atom and creating waste that takes thousands of years to become safe?... its all as bad as each other... don't let them kid you...its all about adding tax ! Did you know that in the UK that farmers can be paid a small fortune per year to have a wind generator put on their land because basically you have ruined the land and it will no longer be of any use for farming ? When they did a massive great crater and fill it with concrete as the base for the heavy machinery going on top, its rendered useless... again not enviromentally friendly is it... !
PS hugging trees- Ivy (the climbing weed) hugs trees... its hugging action grips around the trees trunk and over time stops the tree from being able to grow thicker as it does naturally... this means it struggles to grow, it struggles to feed its growing limbs and eventually it is strangled to death... even tree hugging isn't good ...
