We need to address those kinds of things and the different technologies. Most of it, if you look at a solar panel in your house or thermal energy, it just doesn't pay today for an average person to upgrade their house with modern technology to make it energy efficient. They won't recover the cost. Most of the time it takes 25 to 30 years to recover that cost, so most people won't invest.
As a government we need to encourage industry to develop these technologies and bring the costs down. It's not going to happen unless we work at it that way to get those things.
There's another thing I wanted to mention. Mark, were you the one who talked about contaminated sites, or was that your partner next door to you?
