I believe you mean low power, not low energy.
TTL is typically lower power than ECL, but not always. Some TTL devices have been higher power than similar ECL devices.

The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
Why ECL family is fastest?
ECL or emitter coupled logic is faster than TTL type logic because the switching transistors do NOT go into saturation in either the on or off state. The switching time from saturation in a high output to saturation in a low state like TTL requires that the junction capacitance be overcome and that the charge in the saturated junction get swept out. ECL is sensitive to a threshold level only.
Why ECL is faster than TTL in digital electronics?
Because in ECL logic Transistors doesn't go to saturation region hence saving the recovery time and making this family the faster.
What is meant by ttl logic?
TTL stands for "transistor-transistor logic" and consists of using BJT's ("bipolar junction transistors") to conduct the logic for the circuit.
Which logic family has the least propagation delay?
Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.
What is ttl circuit?
A digital circuit composed of bipolar junction transistors (BJTs). Widely used in all variety of electronic applications, especially prior to CMOS circuits becoming popular, TTL superseded the earlier RTL (resistor-transistor) and DTL (diode-transistor) logic designs, which used more power. In TTL, transistors are used to both isolate inputs and perform the logic switching. A "TTL" designation on a circuit input or output indicates a digital circuit rather than analog.Read more: transistor-transistor-logic-electronics
TTL logic is preferred to DRL logic?
TTL is faster and does not lose amplitude

What does TTL applies mean?
TTL is a logic family. A logic family is the set of logic gates designed using a specific approach. Or simply speaking, logic family is the way of implementing logic. TTL stands for transistor - transistor - logic. It involves transistors (BJT) to implement logic. TTL applies means TTL logic family is used or can be applied in that specific application.

What is meant by standard load in digital electronics?
One standard load is the load of a typical input of a specified logic family. This is more relevant with bipolar logic families (e.g. RTL, DTL, TTL, ECL, I2L) than MOS logic families (e.g. NMOS, CMOS). Outputs of devices in these logic families are then rated by the number of standard loads they can drive. However when crossing between logic families (e.g. LS TTL to S TTL) the concept of standard loads is less useful and actual high/low state input current loading and output drive capability calculations should usually be made.
Why do TTl integrated circuits assume unconnected inputs to be at logic?
Unused ttl inputs would normally default to logic 1 if left floating. but these inputs could act as antennas under certain conditions and they could pick up noise which can cause the circuit to malfunction.
