Lubrication and/or bearings, of various types, were the new techniques adopted by human beings to reduce energy loss due to friction.
Energy wasted due to friction is converted mostly to heat.
Friction can produce energy in the form of heat
false
Friction converts movement into unusable energy.
Friction converts kinetc energy into heat energy.
One of the examples is vehicles are designed in "AERO DYNAMIC" model.
The human body creates synovial fluid, which is found in our joints. This is a lubricating fluid, which reduces friction. When a joint loses its synovial fluid, bones can touch each other, which causes joint pain. This can be alleviated medically by having a series of joint injections with an artificial synovial fluid called hyaluronic acid. There are two common supplements, which are also used to reduce joint friction, glucosamine and chondroitin.
No, energy transfer is not the same as friction.
Energy wasted due to friction is converted mostly to heat.
Friction can produce energy in the form of heat

Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
from friction
Friction is NOT energy. Friction is a FORCE (rather than a form of energy). It can be used in the formula: W = F·d where "W" stands for work (which IS energy), F stands for force (like friction), and "d" stands for distance over which the force is exerted. Typically when friction is present some kind of energy of motion such as mechanical energy or kinetic energy or potential energy is being transformed into heat.
