# How does a energy generator work?

It has an electrical circuit in it that is designed to produce energy. It has a power output of 2.1 Watts/gallon (W/gallon), and it has a fuel to generate an electrical current to run the device. If it were to run off a fuel, the vehicle would need to use that fuel.

How does an energy efficient engine do that?

An efficiency level of 85% is considered “extremely efficient” by energy efficiency agencies. The reason is because efficiency is not defined by the amount of energy being used. Rather, efficiency is defined by how efficiently the fuel is used. That means that an efficiency level of 85% means that in energy output, 95% of that energy is converted into mechanical work of some sort.

That makes sense, doesn’t it? The energy a gasoline engine produces can be put into any number of applications and processes, because it is only about 10% of the total energy input. However, it is the total amount of energy that’s actually used to produce that fuel that determines that efficiency level.

What the heck does that mean?

“Energy efficiency” is a term that is used to describe a vehicle’s performance, its ability to generate energy, by measuring the energy it uses to run itself and the total energy required to produce. When we use fuel to generate energy, we are actually using more energy than is actually needed. In that sense, you would call your vehicle “energy efficient” if its efficiency rating was 50% or higher.

How can someone explain “extra energy” without understanding “energy efficiency?”

A vehicle’s internal combustion engine is what converts the energy to mechanical work of some sort. We cannot have a vehicle produce all of that energy by itself, only in ways where the mechanical work is provided when the vehicle is in motion. And, like any other process, an energy producing process takes energy to achieve a certain amount of mechanical work. So, we use energy production to describe a driver’s ability to drive the vehicle.

The more power a vehicle generates relative to its weight, the more energy it uses. As such, the more energy needed to fuel the vehicle, the less efficiency is obtained.

Okay, but what about electric vehicles?

An electric car cannot just sit idly there idling, either. The energy required to charge the battery and drive the vehicle goes toward moving the electric motor. The vehicle moves with the electric motor by converting mechanical energy toward electric power until the fuel
