UK Faces Power Blackouts In Squeeze for Profits, Low-Carbon Energy
"Britain could face a return within 18 months to 70s-style power rationing to prevent blackouts, screamed one tabloid front page on Friday, conjuring up a vision of coalminer militancy and the three-day week.

Now private sector companies such as Centrica, which owns British Gas, and the other big six energy generators mothball or close any power plants that are not making good returns.
Currently many gas plants have been taken offline because gas is considered too expensive compared with coal,
which is very cheap because of exports from places such as America where shale gas has led US power plants to shift in the opposite direction."

In case you were deluded into thinking Obama's cuts in U.S. carbon emissions would have any significant impact on climate change (if the UK won't burn American coal, there are plenty of countries that will).
