Cramer: Green Trucks Turning a Corner

Brand new developments could mean big things for alternative energy and the related stocks.

"I have been pushing natural gas as a bridge fuel to the future for ages now," Cramer explained.

And according to a report in the New York Times published on Wednesday, the trucking industry may now share Cramer's enthusiasm.

In a piece titled, "Trucking Industry Is Set to Expand Its Use of Natural Gas," the paper said the trucking industry is making sharp advances in the switch from gasoline and diesel fuel to cleaner burning natural gas.

"In the latest sign of how the momentum for natural gas in transportation is accelerating, United Parcel Service plans to announce in the next few days that it will expand its fleet of heavy 18-wheel vehicles running on liquefied natural gas, or L.N.G., to 800 by the end of 2014, from 112. The vehicles will use the new Cummins engines, produced under a joint venture with Westport Innovations," the paper said.

If the Times article is a sign that alternative fuel is starting to get a foothold in the trucking industry, then Cramer thinks it may be a good time to put money to work.

Although there are many related ways to play developments, Cramer thinks Clean Energy Fuels deserves attention. "Clean Energy is building out a fueling station network on major trucking routes across the interstate highway system, from coast to coast and border to border," Cramer said.

If more trucking companies embrace nat gas and also convert their fleets then, "Clean Energy could be the stock to buy," said Cramer

However, the Mad Money host added this play as well as other ideas on alternative energy remain in their infancy. "Therefore, this stock as well as most others are only for speculation," he added.
