In the video feature, Best Trades Now: Healthcare, Energy & More, what does Edward Perks call “a tremendous performer”?

Canadian Oil Sands (COSWF) has been a tremendous performer, really driven by the oil-price performance the last several years.  Others, like Pfizer (PFE - Annual Report), have been a little bit tougher, a little bit more of a long-term value play, with the creation of new drugs there over time.”

On Wednesday, Cramer revealed his Wind Index. Which “Windex” stock was NOT one of his previous calls?

But there are four other names, most likely new to Mad Money viewers, that Cramer’s using to round out the Windex.

Ameron (AMN) deals mainly in water pipeline systems but also has a wind-tower manufacturing business that could double in size this year.

The three other stocks all trade over the counter here in the States. Vestas

 (VWDRY), the largest play on the global wind market, Cramer called it, that makes wind turbines and towers; Broadwind Energy (BWEN), a wind-farm construction and infrastructure play that also makes wind tower; and Clipper Wind Power (CRPWF), a turbine manufacturer based in the United Kingdom.

I have written about another Windex member, Thomas & Betts (TNB) here.

The geothermal industry is molten! But there are only 2 pure plays trading on U.S. exchanges. Name one.

Though there are just two pure-play choices trading on US exchanges - Ormat Technologies (ORA) and US Geothermal (HTM - Annual Report), there are a dozen combined in Canada, Australia, the UK and New Zealand.
