Admit it. You’ve thought about writing an ebook. In fact, you’ve already imagined the front cover. You can see the main title and, underneath, your name. And when you picture it, you feel a ripple of pride. An ebook would be a big step up for you as a writer. Because while blog posts and freelance writing gigs are great ways to express your ideas and earn a side income, you can’t help feeling they’re a little, well, fleeting. Lightweight even. But your own ebook? That’s more substantial. It’s taken more seriously. It has more gravitas. And having an ebook with your name on the front transforms you from a mere writer into that more impressive beast — an author. But how do you become an ebook author without falling victim to the same mistakes that sabotage the attempts of so many other writers and bloggers?

On the surface, ebook writing seems relatively easy. Lots of writers seem to be doing it, so how hard can it be? But in reality, most ebooks that see the light of day are horrible. Embarrassingly bad. That’s because your average ebook writer doesn’t have a clue how to write an ebook. They can’t afford to hire a ghostwriter, and they don’t have the support system a traditional author would be given by their publisher when writing a print book. They do their best, but they don’t know what they don’t know. The good news? We can learn from their bad decisions. In this post, we’re going to show you the common mishaps first-time authors make when writing an ebook.
Response: We know you've dreamt of writing your very own ebook with a captivating cover and a catchy title as it could spark your writer's career by placing you center stage, unlike those blogs and freelancing gigs. It's a one-way ticket to go from a writer's stage to an author's, but it's not without its obstacles. How can you write an ebook while avoiding bad habits and misconceptions? 

While the popularity of ebooks may lead you to believe it's easy to write one, the truth is, most of them are blatantly bad, because most people don't know the first thing about writing ebooks and they can't afford to hire ghostwriters either. Even with their best efforts, there're some areas they simply can't get the hang of. Fortunately, you can learn from those mistakes as we narrow down some of the most common mistakes made by beginner ebook authors.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the following text: In recent years, renewable energy sources such as wind, solar, and hydro have become more popular due to their environmental benefits. Unlike fossil fuels, which release harmful pollutants and greenhouse gases when burned, renewables produce electricity without emitting pollutants. This makes them an essential tool in the fight against climate change. Additionally, technological advances and increased investment have made renewable energies more affordable and efficient than ever before, paving the way for a cleaner, more sustainable future.
