Every Monday, Jim Cramer answers questions from followers on Twitter. Today he was asked which he preferred as a long-term play, Schlumberger or EOG Resources. Cramer likes them both, but if he had to pick one he'd take Schlumberger for the long haul. Another follower asked about coal names since they spiked on Friday. Cramer conceded that coal seems to be moving as the energy sector goes higher, but in general he does not like coal. Then finally, Cramer talked about alternative energy because many consumers want to know if domestically we can be energy independent. Cramer names his favorite alt energy stocks.
