As an outright technology, neither. Every model is different. You should look at the detailed technical specifications of the models you are interested in. Most these days will list the power consumption values on there. You can then get an idea of how different models stack up against each other.
Plasma can compete with or equal LCDs now with the new modern models. But matching LED LCDs might be hard, even for the brand new Plasmas. If you're okay spending the money required for an LED LCD, then you can get likely the best power consumption option from there.
Because of how LCD TV sets work, they will enable you to save more on electricity costs than plasma TV sets. But the difference between both energy costs is minimal so this must not be considered as a primary factor in the decision-making process.
