Friction affects the efficiency of a system since two objects rub against each other. When this happens, there is created which reduces the energy in the system.
It converts some of the system's kinetic energy to thermal energy
CUZ IT CAN NEEEEEEEEEERD
Energy wasted due to friction is converted mostly to heat.

Friction will slow down the moving object
According to the laws of thermodynamics, energy can never be "lost" or "made". Energy, in a closed system, is always constant. Energy can however be "lost" to the environment, for instance by friction. If you drag a box over the floor, some of the energy you are putting into moving the box is being "lost" to the environment by friction between the box and the ground (and a very small amount to air friction). You could therefor say that friction is a cause for "loss" of energy.
Friction
Friction reduce the velocity, hence, it affect kinetic energy. The potential energy from static pressure is then drawn to maintain the velocity (transformation of potential -> kinetic energy). We then see the friction reduce the static pressure but actually, it affect kinetic first.
The factors affecting kinetic energy are mass and velocity.

Friction always want to retard the motion of a moving object. So friction slows down and finally stops a moving object.

Friction converts kinetic energy into heat. The result is that the moving body slows down.
