I completely agree... I mainly mean that some resources are less of an impact or more cost effective than others. I'm all for working to reduce pollution for the sake of, and if that means less carbon in the air, awesome. However, if your goal is really reducing some footprints then what materials are used/needed for construction and distribution have a huge impact. Not to mention the infrastructure security of potentially key infrastructure (power grid) relying on parts from an adversarial foreign state.
