I think one of the biggest problems that inventors of “green” or environmentally more responsible products face is getting builders to use their products. I might be wrong, but it seems that this is often the case. Usually such products are not as easily obtained and often cost more than what is nationally available for construction.
According to this recent article from the NAHB though, half of new homes are expected to be built using green products by 2010. This is good news and i hope the trends continue in that direction. Green products are not as available as I wish they were in our area, I rarely see people using these types of products.
