Consider the fundamental relationship:
Energy = power x time.
That simply precludes energy being instantaneous.

Electrical Energy as Wh or kWh = Power x Time. As I indicated, for the rate to have useful meaning in the context of measurement of energy, the context of the passage of time is implied. Power is the rate at which energy is transmitted. For this to have useful meaning in the context of the articles, it implies time and is little use without time. In the context of the articles, time spans the course of one year.
The articles are remarking about power in yearly terms based on average expectation, being the average amount of work done or energy transferred per unit time. Time is implied in this context in regard to power. In that context of the articles, the power measurement being referred to is not instantaneous and does not have to be, as they are talking about energy and average power expectation over one year and not about
Delta t approaching zero. The articles are still correct to speak about power in the context they have conveyed. It's evident you have tried to alter the interpretation of the articles to try to make a point, that the articles don't make themselves.
Energy is ever present and always instantaneous. Energy exists irrespective of power, but power requires energy to be measured and to have practical meaning, work has to be done.
