Thank you, Mr. Chairman.
I much appreciate the fact that you are all talking about the same thing, namely integrating the various energy sources to arrive at something. There is a term that I have not heard often, but it was used here, and it applies to all buildings. I am talking about passive solar, which is of extreme importance. There is nothing to sell, but it is of extreme importance. Codes and requirements could help reinforce this concept, and this is already in place. There are countries that use passive solar on a broad scale. You talked about Germany, and I am very familiar with the situation there.
You talked about geothermal, you in particular, Mr. Oliver. You talked about geothermal within your overall system. Geothermal really represents the future, but we must not forget that deep geothermal can produce electricity. Natural gas remains a non-renewable resource.
There are 24 countries that produce electricity in this way. In the United States, a lot of research is being done. Are you not of the view that Canada should, it too, undertake research on deep geothermy, in other words, at a depth of 2 to 5 kilometres, as a means to produce electricity.
