The terawatt-hour and petawatt-hour are large enough to conveniently express annual electricity generation for whole countries.
The hydroelectric plant generates between 1 and 2 terawatt-hours of electricity annually.
An energy saving of 18% is equivalent to a drop in energy consumption of 1 900 terawatt/hours.
Of that generation, 19.7 terawatt hours are currently from nuclear power.
What are the problems in achieving, for example, those 19 terawatt hours?
The laser is capable of a maximum output of 2 terawatts, but is currently operating at 1 terawatt.
Terawatt lasers produce faster electron acceleration.
Terawatt lasers produced fast electron acceleration.
