Answer
Our current fuel usage may be a crisis, as we are relying heavily on nonrenewable resources such as coal, petroleum and gas, which are finite and cannot be quickly and easily replaced. To improve our fuel usage, we should focus on transitioning to renewable energy sources such as solar, wind and water, which are more sustainable and can be replenished through natural processes. Evidence collected from investigations has shown that renewable energy sources are becoming increasingly cost-effective and efficient, making them a viable option for reducing our reliance on fossil fuels.
