I would say that in terms of major transmission lines we are world leaders in technology. We are some of the most significant innovators in large transmission technology, which is not surprising given the distances that we have to move commodities like natural gas across the country.
Downstream I would say we are further down the list as innovators. Many of our technology applications for natural gas are fairly dated. That's why we recently started this ETIC initiative I referenced, in an effort to start to move us up the value chain, or rather up the technology list of countries that are innovators, because we think there are significant innovation opportunities for natural gas.
The second part of your question is about the technical skills and the technology capacity within the industry. It is remarkable. People assume that, as a resource industry, it is just a hewers of wood and drawers of water kind of industry, and of course it isn't at all. The technical skill level is extraordinary right across the value chain. These are highly paid and highly skilled employees, not only on the extraction side of the industry but in the transmission companies and in the distribution industry. In the distribution industry we're looking at about 13,000 to 15,000 employees across the distribution companies.
