What type of energy sources are emphasized in sustainable energy practices?

Sustainable energy practices emphasize renewable sources because they are inherently sustainable and less harmful to the environment. Renewable energy comes from natural processes that are replenished constantly, such as sunlight, wind, rain, tides, waves, and geothermal heat. Harnessing these resources allows for energy generation without depleting the Earth's natural capital or contributing significantly to pollution and greenhouse gas emissions.

In contrast, non-renewable sources, which are derived from finite resources like fossil fuels (coal, oil, and natural gas), contribute to environmental degradation and climate change. Importing energy is also not aligned with sustainability, as it often relies on non-renewable sources and may create dependencies on external supplies. Therefore, focusing on renewable energy sources is essential for achieving long-term sustainability goals. This shift not only mitigates climate impacts but also promotes energy independence and security for communities.
