And in the information era you know what, we really see is a more
extensive diversification of our primary energy resources
but largely defined by in you know,
what I'd like you to be thinking about is largely defined by the type
of work that people are seeking which is electrical work that they are using.
That's what they are consuming or thinking about demand at this point.
So certainly there is, you know, lots of use petroleum products in transportation.
I'm not diminishing that in respect but the
really distinctive aspect of the technologies that are new.
And in wide use in this period are technologies using electricity.
So we have a growing portfolio of types
of primary resources that can be used for electricity.
Not only coal, but also natural gas for gas fire generation, nuclear and other
renewables finally starting to finally take off at the end of, of this period.

So what I'd, I think that this chart illustrates
relatively well, the importance of the technologies and therefore,
the types of work we're deriving from these technologies,
for thinking about the different eras of primary energy use.
Through the U.S. and in principle you could put
this together for any country that you want to.
But [SOUND] I don't think that this
chart explains everything, because what our tech,
what our technological delineation here is show, is suggesting is that we're sort of
substituting from one type of, energy to another type of energy, when in fact,
towards the latter part of this period,
pretty much demand for everything is just exploding.
So what our, our delineation by technologies does is a
good job of, of sort of telling a story how we're,
how we're seeing substitution maybe
between certain technologies and maybe Emergence
of certain energy sources and emergence of new primary energy sources.
But it doesn't really explain everything and so what I'd like to do in the next
video is provide a brief overview of the determinants of demand.
So sort of, we'll, we'll do a bit of a general micro
economic discussion of demand determinates to try
to add a little more context to what's going on
with energy demand as we move into the 21st century.
