Cramer's 'Mad Money' Recap: Fight the Panic

Going Nuclear

It's time to take a look at NRG Energy (NRG Quote) because it pays to invest in pollution-reducing companies, Cramer said.

NRG, he said, wants to be a nuclear plant company. He said the company has applied for two new reactors in Texas, and they could go up in 2014 and 2015 if they are granted approval.

David Crane, president and CEO of NRG, joined Cramer on his show; he said the lowest marginal cost alternative is coal, partly because the carbon emissions from coal are free. However, he believes nuclear power eventually will be the significantly cheaper way to create energy. The added bonus with nuclear, Crane added, is that there are zero air emissions related to nuclear power.

The chief executive said NRG has been moving faster than other companies to get approval for their nuclear reactors.

Commenting on other energy plays, he said wind power, though it works in a high gas-price environment, is reaching a saturation point. He also said wind turbines come from Europe, and the cost for them is now is "killing" companies.
