Perhaps researching the history of energy usage in the country under question will provide you with, not only data, but also a perspective for your argumentative essay. For instance, nations under Communism were often behind in energy advancement. (Interestingly, there was recently taken an aerial shot at night of Korea. South Korea was lit up everywhere, but large areas of Communist North Korea were in complete darkness. So, it is clear from comparisons of the Koreas, as it was between East and West Germany before and, certainly, after the Berlin Wall came down in 1989 that capitalism provides more opportunities for energy advancement. (There are other factors, of course, that must also be considered.)
Certainly, with energy comes progress; with progress comes improvement (economic, social, etc,) This idea can be one around which you can build a thesis of at least three sound arguments.
Using examples and statistics, you can build your argument. Do not forget, too, to consider the argument from the other side and refute it. a referrall to Enotes "How to write an Argumentative Essay" will, indeed, be beneficial.
The best way to begin an essay is with an introduction that catches your reader’s attention, has a clear thesis, and previews the argument being made.
Any essay should begin with a good introduction. It’s fine if you don’t have any ideas for a good hook to begin your essay. Start with writing the thesis. A thesis statement is a clear, specific statement that describes your argument. You will want to explain what country you are talking about, and what the future of energy is there according to what you will be arguing in your essay.
Once you have a thesis, go back to your first sentence—the hook. The hook is the first sentence of the essay, and its job is to catch the reader’s attention. A good place to start when trying to decide on a catchy hook one a topic like yours is statistics. Find an interesting or shocking fact or statistic, and open with that.
