Which of the following statements is true regarding renewable energy sources?

The statement regarding renewable energy sources being essential for sustainable energy production is accurate because renewable energy plays a critical role in addressing climate change and reducing environmental impact. Unlike fossil fuels, which are finite and contribute to greenhouse gas emissions and air pollution, renewable energy sources such as solar, wind, hydro, and biomass produce little to no emissions during operation.

Integrating renewable energy into the energy mix helps ensure a more sustainable future by providing cleaner options, reducing dependency on non-renewable resources, and promoting energy security. As countries invest in technology and infrastructure for these energy sources, they contribute to long-term sustainability goals and foster a transition towards greener energy systems.

The other statements do not accurately reflect the characteristics or current realities of renewable energy. For instance, the reliance on fossil fuels and the claim that renewables can replace non-renewable sources immediately overlook the complexities involved in energy infrastructure and market dynamics. Moreover, while operational costs of renewables have been decreasing, suggesting they are generally higher than fossil fuels might not align with the current trend of cost-competitiveness in many regions.
