Now that we've had a month to reflect on the horrible aftermath of hurricane Sandy, one thing is very clear: our nation needs a new power grid.

"I think this storm was a wake up call to government officials and the utilities they regulate all over this country to finally start fixing our aging electrical infrastructure," said Jim Cramer.

One of the reasons why it took days or even weeks for people in New York and New Jersey to get their electricity back is because their power grid was outdated. The equipment should have been replaced ages ago.

And Cramer thinks after Sandy the nation will start to take the issue very seriously.
