While we need to add energy to Earth to take it further from the sun's gravitational well, this actually results in us slowing down (while increasing the radius of orbit). In order to orbit farther away the year _must_ get longer. I have no idea what distance would be necessary relative to Mars/Jupiter/asteroid belt.

It is less delta-v expensive if you increase velocity to change orbit rather than a direct push away. Not sure how else you'd propose changing the orbit.
