The potential solar energy that could be used by humans differs from the amount of solar energy present near the surface of the planet because factors such as geography, time variation, cloud cover, and the land available to humans limit the amount of solar energy that we can acquire.
Irony Definition. Irony is a figure of speech in which words are used in such a way that their intended meaning is different from the actual meaning of the words. It may also be a situation that may end up in quite a different way than what is generally anticipated. In simple words, it is a difference between the appearance and the reality.
Irony is a literary device where the chosen words are intentionally used to indicate a meaning other than the literal one. Irony is often mistaken for sarcasm. Sarcasm is actually a form of verbal irony, but sarcasm is intentionally insulting. When you say, Oh, great after your drink has spilled all over your expensive new clothes, you don't actually mean that the incident is positive.
