Here is an example of how to make the best use of the home you have – however un-eco it was to start with.
Pete Vigs has slashed his family’s energy use by converting to a net-zero solar powered home that uses no oil or gas.
His 4 part video (click keep reading to see it) shows all the changes he’s made, three years into a 10 year peak oil preparedness plan. To his surprise, his life is now better while using much less energy and having less impact on the environment.…

A sunspace is usually a light-frame enclosure made of glass or other transparent glazing, aluminum or wood framing, windows, skylights and sliding glass doors. Also known as conservatory, greenhouse, solarium, or sunroom.
Pre-engineered sunspace kits (such as this one) are available in a variety of sizes and styles but be careful to find one which specifically aims to enhance the solar heating capacity if that is what you are after.…
