Petroleum Exercise
Imagine you are a government official responsible for creating a policy to address the future of petroleum in your country. You need to consider the environmental impact of petroleum while also ensuring energy security. Based on the information you learned, create a plan outlining three key actions your government should take to balance these factors.
Exercise Correction
There are many possible solutions, but here are some examples:
1. **Invest in renewable energy development:** The government could offer incentives for renewable energy projects like solar, wind, and geothermal power. This would help reduce reliance on fossil fuels and mitigate climate change.
2. **Promote energy efficiency initiatives:** Encourage energy efficiency measures in homes, buildings, and industries through regulations, tax breaks, and public awareness campaigns. This would reduce petroleum consumption without compromising energy security.
3. **Develop and implement sustainable extraction and refining practices:** The government could enforce stricter environmental regulations on oil and gas companies, promoting cleaner extraction techniques and reducing pollution from refining processes.
This plan should demonstrate a balanced approach to addressing both energy needs and environmental concerns related to petroleum.
