Clean energy sources, such as solar, wind, and hydropower, are often thought to be «clean» because they produce minimal or no carbon dioxide (CO2) emissions. However, there are still some environmental impacts associated with these clean energy sources. For example, large-scale solar farms can take up large amounts of land, and wind turbines can disrupt bird and bat migration. Additionally, some of the materials used in the construction of clean energy sources, such as the rare earth elements used in solar panels, can be hazardous to the environment if not disposed of properly.

Why clean energy is not possible?

Clean energy is possible, but it is not always the most practical or cost-effective solution. In many cases, clean energy technologies are more expensive than traditional energy sources, and they may require significant upfront investments in order to be implemented. Additionally, many clean energy sources are intermittent, meaning that they may not be available at all times and may require additional storage or backup systems to ensure reliable energy supply. Furthermore, the availability of renewable energy sources can vary greatly depending on the geographic location, making them less reliable for large-scale energy production.

What renewable energy is not clean?

Some of the renewable energy sources that are not as clean as others include biomass burning, nuclear energy, large-scale hydropower, and geothermal energy. Biomass burning produces carbon dioxide, nitrogen oxide, and other pollutants. Nuclear energy produces radioactive waste. Large-scale hydropower can have a negative environmental impact, such as reducing fish populations and disrupting river ecosystems. Geothermal energy can produce hazardous gases and can cause seismic activity.
