It may take some time to pinpoint the exact cause of India's massive blackouts last week, but the underlying issue for India and many other parts of the developing world is that supply is struggling to keep up with the growing demand for power — an imbalance that can affect the reliability of electric grids.
In India last week, surprise grid failures plunged more than half the country into darkness. But power outages in neighboring Pakistan have been intentional — the result of summertime energy rationing.
Despite billions of dollars in U.S. aid, Pakistan has been unable to keep the lights on. Now the situation is getting worse, with riots erupting over factories forced offline.
The 2010 elections were a coming of age for the Tea Party, with big gains in Congress and in statehouses. As 2012 approached, the movement was looking for similar success. Then came this year's GOP presidential primaries, with no surviving Tea Party favorite.
Polls showed public support for the movement falling off significantly after several nasty showdowns in Congress. But the Tea Party remains a force in many states. Its favored candidate for the U.S. Senate won big in Texas last week, sending the strongest signal yet that the movement will be a factor this fall.
