Renewable energy generates electricity. Renewable energy sources such as solar, wind, hydro, and geothermal power are used to generate electricity through various technologies. For example, solar panels convert sunlight into electricity, wind turbines harness the power of the wind to generate electricity, and hydroelectric power plants use the energy of flowing water to produce electricity. Therefore, renewable energy is a key source of electricity generation that can help reduce reliance on fossil fuels and mitigate climate change. **

Electricity from renewable energy sources has become increasingly competitive in terms of cost, and in many cases, it is now cheaper than electricity from traditional sources such as coal or natural gas. The cost of renewable energy technologies like solar and wind power has been steadily decreasing, making them more affordable and cost-competitive. Additionally, the long-term costs of renewable energy are often lower due to the lack of fuel costs and the potential for lower maintenance expenses. As a result, many regions are now seeing renewable energy as a cost-effective option for electricity generation. **

In 2020, renewable energy sources made up 46.3% of electricity generation in Germany. This is a significant increase from previous years and reflects the country's commitment to transitioning towards a more sustainable energy system. Renewable energy sources such as wind, solar, and biomass have played a key role in reducing Germany's reliance on fossil fuels and lowering carbon emissions in the electricity sector. **

I cannot determine whether the subscribers were purchased or not without more information. If the subscribers were acquired through legitimate marketing efforts and organic growth, then they are likely genuine. However, if the subscribers were obtained through purchasing fake accounts or using unethical methods, then they would be considered purchased subscribers. It's important to build a genuine and engaged audience through authentic means to ensure long-term success. **

As of now, the YouTube subscribers are not decreasing. YouTube continues to be one of the most popular platforms for video content, and many creators are gaining new subscribers every day. The platform's user base is constantly growing, with more people creating and consuming content on YouTube. **

YouTube stopped showing exact subscriber counts on channels in 2019 in an effort to reduce the emphasis on numbers and to focus more on the quality of content. This change was made to create a more positive and less competitive environment for creators, encouraging them to focus on creating engaging content rather than just trying to increase their subscriber count. **

As of September 2021, the YouTuber with the most subscribers is T-Series, an Indian music label and film production company. **

Subscribers see YouTube as a platform that provides them with access to a wide range of content creators and videos that align with their interests and preferences. They view it as a source of entertainment, information, and inspiration, where they can discover new content, engage with creators, and connect with like-minded individuals. Subscribers also appreciate the ability to customize their viewing experience through subscriptions, notifications, and personalized recommendations. **
