English is a second language for me. If I translate literally from my native language, I'll say, "The electricity has gone." and "The electricity has come".
For the first sentence, we say things like
What is the correct way to express what I am trying to express the second sentence?
In Britain we could say,
The power/electricity is back on.
We (folks in California) sometimes say "Power has been restored."
I have quite often heard the following:
In my experience, the word power is used much more often than electricity when referring to the stuff coming out of a (ahem) power socket, even though, strictly speaking, it is a less accurate term.
Down vs Operational
e.g.
Power is down on the entire peninsula.
vs.
Repairs were completed overnight; power is operational.
On/Off-line and "knocked out"
e.g.
The emergency generator will compensate locally while the mains are still offline.
and
The storm knocked out phone, cable, water, sewage, gas, and power, and it would be weeks before utilities were back online.
Dark vs. Live
Sometimes screenwriters will have characters referring to remote installations using military-sounding jargon, such as Paris is dark vs New York is live --beyond describing broadcast or communication ability, could also indicate whether site has power.
