<p>The future outlook for the use of oil, coal, and gas as sources of energy includes current reserves of over 22 billion barrels of oil, over 800 gigatons of coal, and 180 trillion cubic meters of gas. Projected consumption is expected to increase, with estimates of undiscovered oil reserves and significant expansion in coal usage.</p> Signup and view all the answers

<p>Strip mining is a production type used for extracting petroleum and involves significant environmental impact such as land disturbance, habitat destruction, and the release of impurities like sulfur, mercury, and arsenic. Challenges include managing and mitigating these environmental issues.</p> Signup and view all the answers

<p>Fossil fuels account for over 80% of primary energy production by humans, but their use leads to the release of CO2 into the atmosphere, contributing to climate change. The significant reliance on fossil fuels raises concerns about the planet's changing climate and the need for sustainable energy alternatives.</p> Signup and view all the answers
