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. **
