Interesting discussions... Ive learned a lot about Fukushima that I didnt realize.
Back agian to the points about wind & solar. Don't get me wrong, I really like wind and solar. I'd be all for it if we could do it all with wind and solar, and dump the FF and stop bothering with nukes, but Im still just not convinced.
Why not? Spain sometimes gets a third of their power from windmills. Last time I was there.. I liked the look of all the ridges with windmills on them.
The example of Wind providing 1/4 of Spain's power, and of the occasional mostly solar days in Germany has been mentioned. Thats all well and great, but can it really scale to the entire world? Or put another way, would the western world be able to keep that up if we hadn't already outsourced a large amount of our energy consumption to the east via moving manufacturing?
Excellent point, lets consider the size of China & India and that part of the world compared to our population in the USA. When they start to consume like we do. The world is gonna a be a whole different place. 1.2 billion for India and 1.3 billion for China with India expected to pass china in 2025. The energy demand for soon to be fully modernized populations like that are mind boggling. 2.9 billion: The combined population of four neighboring countries: China, India, Pakistan and Bangladesh. Together, they account for 41 percent of the world's population.
This is key, as the growth of China, India, "Chindia" or the BRIC countries has major energy implications.
- These countries are huge and growing like crazy, so even with only a fraction of our per capita consumption that are straining the available resource base like never before
- They all have large and growing middle classes that DO want to consume like Americans
- By moving 80% of our manufacturing to these locations we have also artificially reduced the western world energy consumption even lower than it truly is. In other words would Spain be all wind if they had to make their own stuff???
As some folks know my job takes me to both India and China on a yearly basis, so I have a keen interest and view of how these countries are developing. I'm writing this from a hotel room in Pudong Shanghai as a matter of fact. When I flew in on Sunday I could see a line of wind turbines on the shore from the airplane. I also see solar water heaters on the roof of many apartment blocks and PV sprouting up all over the city. You might be surprised how much attention is paid to efficiency here as well - everywhere I go in hotels, offices, etc they try to turn off everything that's not in use, have installed high efficiency lighting, etc.
That's all great but doesn't negate the fact that China's consumption of Coal, oil, gas, nuclear is all growing exponentially. Wind is no magic solution here.

Its also easy to look around in the US and see people still merrily driving and think the situation with oil is just dandy. But go to India and ask the locals what they think of prices, or watch the petrol riots and you will have a different view....
