simple past tense and past participle of power
"The old car was powered by a small engine that we installed last week."
In plain English: To be powered means to have energy supplied to you so that something can work or move.
"The car is powered by electricity."
Usage: Do not use "powered" to mean "driven by" or "propelled by," because that is incorrect; instead, use it only for the simple past or past participle of the verb "power," which means to supply energy. For example, say the engine powered the car rather than the car was powered by the engine.
(often used in combination) having or using or propelled by means of power or power of a specified kind
"powered flight"
"kerosine-powered jet engines"
Having its own source of power, or a named source.
"The new electric vehicle is powered entirely by solar panels installed on its roof."
In plain English: Powered means something is running or working because it has electricity or fuel giving it energy.
"The new electric car is powered by batteries instead of gas."
Usage: Use "powered" to describe something that operates using an internal energy source, such as a vehicle running on fuel or electricity. Do not use it to mean simply having electricity available in the area, as that describes being "powered up" or "connected."
Derived from Old French poder (to be able), this term entered English via Middle English as powren, originally meaning to make strong or capable of action. It is now used as the past tense and past participle of the verb "power," indicating that something is supplied with energy or driven by a source.
