Câu hỏi:

As the demand for energy increases worldwide, many countries are turning to renewable sources as an alternative to fossil fuels. Unlike coal and oil, which take millions of years to form and cause significant pollution, renewable energy is sustainable and environmentally friendly.

One of the biggest advantages of renewable energy is its ability to reduce greenhouse gas emissions. By using solar, wind, and hydropower, nations can lower carbon dioxide levels, helping to slow global warming. Additionally, renewable energy enhances energy security, reducing dependence on imported fuels and making countries more self-sufficient. Despite its many benefits, there are challenges to adopting renewable energy. The initial cost of installing solar panels or wind turbines is high, which can make investment difficult, especially in developing regions. Furthermore, renewable energy production depends on weather conditions, making supply less reliable in some areas.

However, with technological advancements and decreasing costs, renewable energy is becoming more accessible. In the long run, transitioning to clean energy will not only reduce pollution but also promote economic growth and create jobs. While fossil fuels will still be used for some time, the future of energy is clearly in sustainability.
