Dear brother, Thesis statement is the distinctive feature of argumentative essays, a thesis statement actually is your stance about a given topic which you have to justify in your arguments. Descriptive essays, such as Energy crisis, causes and consequences, do not require any Thesis statement because there is a given topic on which you have to write, its not like an argumentative essay where you have to take the sides.

For example, look at your thesis statement, was it really required? No, because we all know from title what this essay is about, on the other hand, the argumentative essays do not have titles such as Energy crisis, rather these have titles like Gender Equality is a myth, Free speech should have limitations etc, where you could have said "Gender Equality is not a myth, its a fact" and "Its is better for free speech to have limitations" respectively.

Regards,
