Missing the Bear: Smart Grid spending in perspective: US & China

0
I like to have my data with a bit of perspective don’t you? (& for now I’ll leave aside the necessary discussion we need to have about this US versus them nonsense.)





I have no idea if this is the right way to compare smart grid spending. I know very little about energy technology and infrastructure. An important consideration is that China, presumably, has a longer way to go in terms of its infrastructure improvement than the US.

Some things I'm not sure of:
Is it indeed more expensive to upgrade an old power grid than to build anew?
Is it safe to assume that there's more energy infrastructure in place already in an urban area than a rural area? And is it more easily (i.e. less expensive) upgradeable in an urban area than rural area?

How about it, out there? I really want to learn so please leave a comment!

Figures for Btu projected consumption

US kWh consumed 2008
Note: US electricity consumption down year on year in 2009, 3.6%, so I was being generous here.

China kWh consumed 2009
I used Chinese government figures because presumably, that’s what they are calculating their spending on, so I don’t want to get into a discussion about how Chinese government figures are exaggerated/inflated/false.

rural figures China

rural figures US (assumes 20% in 2000, generalized to 2008 estimate)

Saudi Arabia makes "green" changes? By whose definition is nuclear, green?

0
The Monocle reports in its November edition that Saudi Arabia has 66.5 years of oil left. Their answer: go nuclear. From the Monocle November issue:


"You know the world is changing when Saudi Arabia, the number one exporter
of oil and gas, is toying with the idea of building its first civilian
nuclear power plant."

(issue 28 (2009), p 74)

Let me get this straight: the "world is changing"?! The world will be changing when Saudi invests in purely renewable energy technologies. Going nuclear isn't changing the world, it's running home to what's close and familiar.

Monday evening I attended London's Green Drinks 20th Anniversary where I'm pleased to say that I've had my opinion on nuclear power in developed countries reversed (thanks to a big ginger-haired fellow and an energy infrastructure geek, where I mean geek in the most affectionate way possible). I now understand that in order to achieve emissions reductions necessary to hold the world at a 2 degree Celsius average global temperature rise that developed countries need to utilize nuclear. But Saudi isn't a "developed" country, it's not even an Annex 1 country. It has got more leeway than that and because it has that extra time should devote itself to finishing the development process clean and green.

"World changing"? Sorry Monocle, you've missed the bear.
