What did you do in the time before peak oil Granma?

The story so far. Once there were two adults and two small boys who created the carbon footprint of a small African village. We burned oil, clocked up a 60 mile-a-day commute, lit a drafty old house with incandescent lightbulbs and left them on when we left the room. (Well one of us did that anyway). Now six months into a radical life shift the commute is gone, I've waved goodbye to my car, shoe-horned my family into a small house and started to plan an eco house. Not the typical house that springs to mind when you hear that phrase. (I picture a straw bale mound by a lake in deepest Leitrim where blonde children play with wooden toys under the gaze of their woollen jumpered parents.) No this eco house is a plain old end-of-terrace in Dublin that I want to drag into an oil-free future by applying the best available green building techniques and renewable energies. Why am I doing this? Yes the future of the planet is a factor. But already I am beginning to realise that a greener life has the potential to be a happier life.
