What are the main challenges and opportunities for transitioning to a more sustainable and environmentally friendly energy system?

The transition to sustainable energy involves reducing reliance on fossil fuels, mitigating greenhouse gas emissions, and promoting renewable energy sources such as solar, wind, hydroelectric, and geothermal power. Challenges include technological limitations, infrastructure development, policy barriers, and economic considerations. However, investments in clean energy technologies, energy efficiency measures, and climate action initiatives present opportunities for creating jobs, reducing pollution, and addressing climate change.
