Cramer's 'Mad Money' Recap: It's Easier Being Green

Moving on, Cramer named Fuel Tech (FTEK Quote) as his "ultimate" speculative play on Green Day.

Fuel-Tech is a play on power companies "forced or incentivized to pollute less," he said. Earlier in the week, Cramer said, he told viewers that Foster Wheeler (FWLT Quote) and Shaw Group (SGR Quote) were his picks for cleaner power. And they still are, for the more conservative of investors.

But for people who don't mind more risk, Fuel-Tech is the stock for them, Cramer said. It has the technology that enables power companies to burn clean coal fuel, he said. It reduces nitrogen oxide emissions and has a fuel chemistry business aimed at saving power. The company "has been getting contract after contract ever since Green Day," Cramer said.

Moreover, because coal provides more than 49% of our electricity, he said, "it's pretty important." We can't solve our problem with ethanol, he said, because it's too inefficient. Therefore, in addition to Green Day, which should force coal-burning utilities to become cleaner, Fuel-Tech is also a play on efficiency, Cramer said.

On a separate note, he told viewers it's a great time to be a bull. And even though the market is up significantly, "there is still room to run."

"I am not exaggerating when I say the best is yet to come," Cramer said. "We are going to be up 17%" this year.
