I'll be sure to tell all of the progressive liberals that I work with how you feel.... /sigh
"progressives" have had nothing to do with the state of the US nuclear industry... an accident occurred and since people are stupid they ran with it. It sure wasn't the average environmental progressive that lobbied for more coal being that it is "safer." People don't understand radiation, this is absolutely not limited to the left or right.
It is also not the only alternative... at all...
1. Are you talking about fusion or something else? The former isn't viable for at least 30 years or so, as someone already mentioned. On the other hand, fission is possible to implement but an average US person thinks it too dangerous.
I agree with your statement that our increasing energy requirements might endanger the heat and energy balance on Earth, although that seems far off to apply yet. As of now to combat our growing energy demand there are two possibilities that I see. Either to continue to grow, albeit more slowly as the currently developing countries become industrialized and find another energy source, like fusion to satisfy our energy demands. Building colonies off other earth-like planets or death(in Malthusian terms) -all are eventualities if the growth rate isn't sustainable.
A second, more economical approach would be to start limiting our population growth in the near future while still advancing technologically increasing the quality of life for all remaining at the end. Definitely not the most popular idea politically.
2. As for the BP crisis, I don't agree that the US population deserves any blame for the incident. One might as well start blaming every private sector disaster onto the public. I think it was a combination of lax regulations and inspections by BP and lack of oversight by the government. It all depends on how much responsibility BP given in its drilling implementation. The more independence it was possibly allowed and thus it abused, the more blame it deserves. The gov't isn't blameless either and should have known better, although one doesn't want it to become a copy of Venezuela either and control the industry as well. A moderate level of state control is key.
Just like it regulates the pollution and environment through the EPA, it should have done the same in this case. A free market without proper controls is dangerous to the public to the extent that pure capitalism always seeks the most profit without regards to the safety of the public in most cases. For example, see China.
