Work is transfer of energy, so it has the same units as energy.
Power is the amount of energy transferred per unit time, so it does not have the same units of energy. Rather, its units are energy/time.

What is difference between fuel and power?
Power is energy that you can put to work, such as the electric current produced from a generator or engine.Fuel is a material with potential energy, it can be used to produce energy.
What is the difference between work an power?
I think force is a better word than power, but work implies that there is something that needs to be done, while power is the energy that is put into work.
What different between power and energy?
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
What is the difference between energy and work?
I have seen different definitions, but basically you can think of work as the "transfer of energy".
Why it is not correct to say that the potential difference is the work done in moving charge between the points concerned?
Voltage is defined as potential difference (units of volts). Work is equivalent to power (over time), and its' unit is joules. Power is equivalent to the potential difference times the current flow. Without current flow, there is no power, so it is incorrect to define potential difference as work. What I think you're implying is potential energy and potential difference are the same: Potential energy of a rock can be increased by raising the rock into the air. The increase of potential energy of the rock is equivalent to the real work done to raise it higher into the air. This is a true statement. Potential energy (joules) and potential difference (volts) are not equivalent, though, since potential differenence is not defined as work.

What is the difference between energy and momentum?
Momentum is the product of mass and velocity. Energy is the capacity of a body to do work.
What is the difference between temperature and thermal eenergy?
Thermal energy can be used to do work. Temperature cannot be used to do work. Thermal energy is actually heat energy in transit.
Difference between energy and work?
The difference of a Joule of Work and Joule of Energy is the difference between a scalar and a vector, direction! Energy is a quaternion number consisting of a scalar energy and vector energy. Unfortunately, this fact is not realized by physicists. Work is defined as a scalar energy W=F.D = - FDcos(x) Vector energy is Torque T=FxD = FD sin(x).
What is the difference between a energy end power?
By Khalid BetaniA classic analogy used to describe power and energy is based on water towers. Water in the tower is energy and the flow of water out of the tower is power. Energy can be stored, like water. It can also flow. When energy flows, it can do work like moving stuff or lighting a house. The speed at which energy flows is called power. The same amount of energy can be released at high power (which will occur quickly) or at low power (which will take more time).
Relation of power with work and time?
Power = energy / time"Energy" refers to transfer of energy, and it may specifically refer to work (which is the transfer of mechanical energy).
How are work energy and power related?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time
