Does litecoin take more electricity to mine than bitcoin?

Does litecoin take more electricity to mine for it that bitcoin or are they the same?

Are there any energy efficient coins to mine?

Thanks

I think https://bitcointalk.org/index.php?topic=163306.0 has some power consumption stats.  In general I think it is... my cards seem to run the fans more than when I mine SHA-256.

PPCoin has some grounding in enviromnental concerns but I haven't read into it that much.  They have a white paper on the coin on their site. http://www.ppcoin.org/static/ppcoin-paper.pdf
