Energy demand and consumption describes the amount of energy required. It is is increasing day by day.
Finned Tubes enhance heat transfer efficiency in HVAC systems by increasing surface area, thereby improving energy efficiency.
It describes how good an engine is at turning fuel into the desired form of energy. High fuel efficiency means that as much as possible of the energy in the fuel has turned into whatever other type of energy that was intended. Low fuel efficiency means there's a lot lost in the transition.
Is it's Energy Efficiency.
Energy management is the discipline and measures executed to achieve the minimum possible energy use and cost while meeting the true needs of the activities occurring within a facility. Actions intended to achieve this energy efficiency focus on reducing necessary end-use, increasing efficiency, reducing wasted energy, and finding superior energy alternatives.
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.

Efficiency describes how well a device transfers one form of energy to another form of usefull energy. High efficiency transforms most of the energy with very little loss. Low efficiency only transforms a small amount into usefull energy and the rest is usually lost to heat energy from friction. For example, a car is a low efficiency device because only a small amount (I forget the actual number. Probably around 50%) of the chemical energy in gasoline actually gets converted to energy of moving the car. The rest is lost to air resistance, friction between all the moving parts & and unused heat out the exhaust pipe.
