Energy Efficiency. A large metalliferrous concentrator HIGmill was equipped with the flat discs. In order to improve efficiency of the power draw and prolong the life of the discs, GrindForce rotors were installed into the mill. Immediately after the installation of the castellated rotors, a benefit in the energy efficiency was observed.

While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

Wind turbine efficiency is a useful parameter for comparing performance of wind turbines to other wind turbines. Comparisons of wind turbine efficiency to the efficiency of other forms of power generation is meaningless and misleading (which is worse than meaningless). Though that hasn't stopped people from doing it all over the internet.
