1. Make your thesis statement, stating the main building blocks of your argument and what you are arguing for. For example, an effective argumentative essay thesis might look like this: “The United States ought to switch their energy dependence from nonrenewable sources to clean, renewable sources of energy like solar and hydropower so that their carbon emissions decrease and the number of available jobs increases.” This states exactly what you are arguing, switching from nonrenewable sources to renewable sources, and the main reasons why you are arguing that.
You want to be able to write the exact opposite of your thesis statement, as the opposing side, and if you cannot do that, then your thesis statement is not contestable enough. Make sure that your thesis is as specific as possible!! You only have two pages, so if your thesis is not specific enough you will not fully argue all the aspects of the issue, making your argument automatically less believable.
