Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Sum up this intro Seoul for me in just one sentence:

Whether you want to see the latest K-pop sensation, take a late-night food and drink tour, or find serenity in a spa or temple, South Korea’s capital has something to offer 24/7. Here are the best things to do in Seoul.

Taste the street food at Gwangjang Market
Street food in Seoul is beloved for its spice, variety and affordability, and there’s no better place to try it than at Gwangjang Market. Dating from the early 20th century, this covered market has gained a reputation among foodies for having some of the country’s best street snacks. 

Start with an order of tteokbokki (stir-fried rice cakes in a bright orange spicy sauce), followed by a couple of mandu (Korean dumplings) and a pajeon (savory green onion pancake). For dessert, try hotteok (a pancake filled with brown sugar and cinnamon) or bungeoppang (a fish-shaped pastry filled with sweet red bean paste). Then do it all over again.
Response: Seoul has something to do all the time, including lots of beloved street food like mandu and pajeon.

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 this passage about renewable energy sources: Renewable energy sources such as solar, wind, and hydro power are becoming increasingly important in the fight against climate change. Unlike fossil fuels, these energy sources are sustainable and have a minimal carbon footprint. Solar power harnesses energy from the sun and can be used for heating, electricity, and even transportation. Wind power generates electricity through turbines that convert kinetic energy from wind into electrical energy. Hydropower utilizes the flow of water to produce energy. Investing in renewable energy not only helps reduce greenhouse gas emissions but also decreases dependence on non-renewable resources and promotes energy security.
