The new District from Trek is the first mainstream production bike to use a belt drive instead of a chain. The carbon fiber composite belt never needs lubrication or the other maintenance associated with mechanically fastened chains. And with less moving parts, you lose less energy to friction/heat and get more energy into moving those wheels.

i wonder how often this belt will need to be replaced? especially in climates of large temperature swings.
Not as often as a chain - belt drives have been used in motorcycles for a while now with fewer problems and less maintenance. Plus - it's a carbon composite material, so temperature swings won't affect it.
