Downlights can be mains powered or low voltage (typically 12 volts) - 'low voltage' does not mean 'low energy', typically the transformer will waste energy, so presuming that you are comparing standard halogen bulbs, overall a low voltage installation will use more electricity than a conventional mains installation.

Installing compact flourescent low energy bulbs is the best option as this will make real savings on the amount of energy that you use to run the fittings.
