What are renewable energy sources?

Renewable energy sources are defined as energy sources that can be replenished naturally over a short time frame. This includes sources such as solar, wind, and hydro power, all of which are derived from natural processes that are constantly replenishing. For instance, sunlight is abundant and can be harnessed into energy as long as the sun exists, wind is generated by atmospheric phenomena, and water can be cycled through natural processes, making these energy sources sustainable and environmentally friendly.

This characteristic of renewable energy is crucial for addressing energy demands without depleting the resources permanently or causing significant environmental harm, unlike non-renewable resources such as fossil fuels or uranium used in nuclear reactions, which are finite and can lead to ecological issues during extraction and use. Thus, renewable energy sources play a vital role in sustainable development and the transition towards cleaner energy solutions.
