Energy lost during friction can be minimized by using lubricants. Lubricants or oil makes the contacted part work smooth without much sliding or rolling and hence fricton is comparitively lower

THE LUBRICANTS ARE A GREAT WAY TO MINIMIZE THE FRICTION . THEY CAN REDUCE FRICTION BUT CANT EVER FINISH OR END THEM.
THE ROLLER BEARINGS ARE ALSO USED NOWADAYS TO REDUCE FRICTION.WHICH SIMPLY WORK ON ROLLING FRICTION.
