What causes a heating element to burn out in a water heater?

Will a water heater work with one element?
Yes, a water heater can still run if the bottom element quits. In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.
Will a bad water heater element use more electricity?

There is no mechanism whereby electrical energy could end up anywhere else.
