Energy

I plug my netbook in at airports, coffee shops, in my office, and at home. I pay the electricity bill at home, but I can't discern any marginal increases when I charge my netbook. I have started turning off my desktop when not in use, but I haven't been able to tell much difference in my bill because of that either. I've read where these electric cars (specifically the Chevy Volt) won't be as cheap as people think because of the increases in electric bills due to charging them. I've heard the cost of electricity will increase in the near future. I know that my electricity bill was high in the winter when my heater had to run all day and night.

The point here is that uncertainty about technology, regulations, government, fossil fuel supplies, etc. abounds. No one knows what is going to happen. But the world keeps spinning. And that is the only energy that matters.
