Ann,

I was thinking in terms of electrical components apparently. Where 48k is 48000, and 48M is 48 million.

Rob,

Thanks!

1. from wiki - A town is only said to have achieved grid connection when it is connected to several redundant sources, generally involving long-distance transmission.

2. from wiki - This redundancy is limited. Existing national or regional grids simply provide the interconnection of facilities to utilize whatever redundancy is available. The exact stage of development at which the supply structure becomes a grid is arbitrary. Similarly, the term national grid is something of an anachronism in many parts of the world, as transmission cables now frequently cross national boundaries. The terms distribution grid for local connections and transmission grid for long-distance transmissions are therefore preferred, but national grid is often still used for the overall structure.

3. The gov is continually looking into grid storage, regulation, and fortification for quite some time now.

4. A lot of the regulation tech is being tested here and there. No overhaul of the electrical grid has been implemented. We still burn a lot of coal. We still lose a lot of energy in heat. I hope to see more work done in this area soon.

Cabe, thanks for the reminder of different technology "vocabularies." I've seen both k and M used in more general contexts to mean thousand, but only MM to mean million. But perhaps general usage is also changing: I just saw M to indicate million in a newspaper article.
