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: Please give me a summary of this. 

The first-ever Barbie doll with Down syndrome has been introduced by toy manufacturer Mattel, who made the announcement on Tuesday. The company had worked closely with the National Down Syndrome Society to ensure the doll accurately represented a person with Down syndrome.   

The doll's dress features butterflies, as well as yellow and blue colors — associated with Down syndrome awareness. Accessories that include a pendant necklace with three chevrons represents the three copies of the 21st chromosome. The doll also comes with ankle foot orthotics, which many children with Down syndrome use for support.

"This Barbie serves as a reminder that we should never underestimate the power of representation," said Kandi Pickard, NDSS president and CEO, in a press release. "It is a huge step forward for inclusion and a moment that we are celebrating."

With its latest addition, "the most diverse doll on the market" hopes to continue to its journey of inclusivity. In 2020, the company's Barbie Fashionistas line featured its first dolls with vitiligo, a doll with no hair, and a doll with a darker skin tone and a gold prosthetic limb. 

Down syndrome is a condition in which a person has an extra chromosome, according to the CDC. Each year, about 6,000 babies born in the United States have Down syndrome and is the most common chromosomal condition diagnosed in the United States. 
Response: In the United States, six thousand people a year are born with Down syndrome - a condition where people have an extra chromosome. To work towards inclusion, diversity, and the power of representation, Mattel worked with the National Down Syndrome Society to accurately release the first Barbie doll with Down syndrome. The doll's dress has butterflies and yellow and blue colors to represent Down syndrome awareness. The doll has a pendant with three chevrons representing the three copies of the 21st chromosome and ankle foot orthotics that many children with Down syndrome use. The Barbie is part of a Barbie Fashionista Line, which features dolls with vitiligo and prosthetic limbs. 

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.

Can you summarize the following passage explaining the concept of renewable energy sources?

Renewable energy sources are forms of energy that are naturally replenished and do not deplete over time, unlike finite fossil fuels like coal, oil, and natural gas. Some common examples of renewable energy sources include solar, wind, hydroelectric, geothermal, and biomass energy.

Solar energy harnesses the power of the sun through photovoltaic cells or thermal collectors, converting sunlight into electricity or heat. Wind turbines capture the kinetic energy of the wind and convert it into electricity. Hydroelectric power plants use the gravitational force of flowing water to spin turbines and generate electricity. Geothermal energy taps into the heat stored within the Earth's crust to produce steam for turbines or to heat buildings directly. Biomass energy is derived from organic matter, such as wood, agricultural waste, or even municipal solid waste, which can be burned directly or converted into biofuels like ethanol or biodiesel.

The use of renewable energy sources has several advantages over traditional fossil fuels. Renewables are generally more environmentally friendly, producing lower greenhouse gas emissions and reducing air pollution. They are also inexhaustible and can be replenished naturally, making them a more sustainable source of energy in the long run. Additionally, many renewable energy technologies have become increasingly cost-competitive with fossil fuels as the technologies have advanced and economies of scale have been achieved.

Renewable energy sources like solar, wind, hydroelectric, geothermal, and biomass are naturally replenished and do not deplete over time, unlike fossil fuels. Solar captures sunlight for electricity or heat, wind turbines convert kinetic energy, hydroelectric uses water's gravitational force, geothermal harnesses the Earth's heat, and biomass burns organic matter. Renewables are environmentally friendly, inexhaustible, sustainable, and increasingly cost-competitive compared to fossil fuels. Their use produces lower emissions and pollution.
