In two to three more years there will be plenty of home/building energy products that will be lowering the amount of heating and cooling - this is where 60% of our energy expense is not in cars. The City of Dallas has new commercial building codes that will require better building efficiency.
The end of the stone age did not happen because of a lack of stones.
What are some of these new home/building energy products that will lower the cost of home heating? I could use some of those right now.
