It will draw a small amount of power all the time, but it will be a
switch mode supply, so it will use a very small amount of power when
it is not in use.
All the power used is turned into heat, so you can assess how much
power is being used by feeling how hot it gets. Then compare that in
terms of a 5 watt light bulb.

Alternative energy. Was: Red diesel. ... The two most common methods used to describe the "break even point" of alternative energy systems are "when the device has produced the same amount of energy as was used to make and install the thing in the first place" OR "when the device has produced the same amount of electricity as could have been bought from the national grid for the cost of the device". ... Either the system can A) store the generated power when available and use it from storage when power is not being generated or B) the system can be connected to the national grid and use the grid as the storage medium. ...
