Assignment 1: Discussion—Nonrenewable Resources Today, more than any other time in history, there is growing support to move away from nonrenewable resources towards developing renewable resources to meet current and future energy needs

Nonrenewable resources are finite sources of energy that formed over millions of years through geological processes. Among these, petroleum (oil) is one of the most significant, constituting a major portion of global energy consumption. The formation of petroleum began in ancient marine environments where organic matter, primarily dead plankton and algae, accumulated on the sea floor. Over time, these organic-rich sediments were buried under layers of sediments and subjected to intense heat and pressure, transforming the organic material into hydrocarbons. This process, called catagenesis, typically takes millions of years, which is why petroleum is considered nonrenewable. The major reserves of oil are located in regions such as the Middle East (e.g., Saudi Arabia and Iraq), North America (e.g., the United States and Canada), and parts of South America, notably Venezuela. Extraction involves drilling wells into underground reservoirs where oil is trapped beneath impermeable rock formations. Techniques such as primary recovery, secondary recovery, and enhanced oil recovery are used to extract oil, with methods including traditional drilling, hydraulic fracturing, and thermal recovery.

The environmental impacts of oil extraction are profound. Oil drilling can cause habitat destruction and pose risks of oil spills, which contaminate aquatic and terrestrial ecosystems. Offshore drilling is associated with risks of catastrophic spills, such as the Deepwater Horizon disaster, which resulted in significant marine mortality and long-term ecological damage. The extraction process also leads to air pollution from the release of volatile organic compounds (VOCs) and greenhouse gases, notably methane and carbon dioxide, contributing to climate change. Additionally, the burning of oil releases pollutants such as sulfur dioxide and nitrogen oxides, which cause acid rain and smog formation. Moreover, the refining process consumes large amounts of water and energy, further exacerbating environmental degradation.

Oil is primarily used to produce energy through combustion, powering vehicles, electricity generation, and industrial processes. The combustion of petroleum releases significant amounts of CO2, a greenhouse gas that contributes to global warming. Other pollution problems include particulate matter and other airborne toxins that adversely affect air quality and human health. In developing countries, oil dependence perpetuates environmental and health issues, especially where regulation and infrastructure are inadequate. Despite these concerns, society relies heavily on oil because it provides a dense and easily accessible energy source, supporting transportation, manufacturing, and domestic needs.

Societal dependence on oil is driven by its high energy density, existing infrastructure, and economic importance. Many governments and industries have vested interests in maintaining its dominance, often influenced by geopolitical factors. Political decisions shape energy policies, subsidies, and exploration activities, which reinforce reliance on oil. Currently, there is a significant political debate over energy independence, climate action, and economic stability, influencing policies on fossil fuel extraction and renewable energy investments. If society were to shift toward environmentally friendly fuels, such as wind or solar, political and economic ramifications would include the potential loss of oil revenue for petrostates, job disruptions in the fossil fuel industry, and the need for substantial investments in new infrastructure and technology. Such a transition could also alter geopolitical dynamics, reduce greenhouse gas emissions, and promote sustainable development but would require significant policy support to navigate economic adjustments and ensure energy security.

Nonrenewable resources, such as petroleum (oil), have been the backbone of modern civilization’s energy system for over a century. The formation of oil is a lengthy geological process involving the accumulation of organic material in ancient marine environments. Dead plankton and algae settled on the sea floor, creating rich organic sediments. Over millions of years, these sediments were buried under additional layers of rock and soil. The resulting heat and pressure transformed the organic matter into hydrocarbons through a process called catagenesis, which is crucial in forming petroleum reservoirs. These reservoirs are predominantly located in regions like the Middle East—especially Saudi Arabia, Iraq, and Iran—North America, with the United States and Canada holding significant reserves, and Venezuela in South America. The extraction process involves drilling wells into underground reservoirs, often utilizing advanced technologies such as hydraulic fracturing and enhanced oil recovery to access difficult-to-reach deposits.

The environmental impacts of oil extraction are severe. Offshore drilling and land-based extraction disturb ecosystems, threaten wildlife habitats, and pose risks of accidental oil spills. The Deepwater Horizon spill in 2010 is a prominent example of ecological disaster, causing extensive marine mortality and long-lasting environmental harm. Extraction activities emit greenhouse gases such as methane and CO2, which contribute significantly to climate change. Additionally, the refining process consumes large volumes of water and energy, releasing pollutants like sulfur dioxide and nitrogen oxides, responsible for acid rain and smog formation. Air pollution stemming from oil combustion affects air quality and human health, with particulate matter and toxins causing respiratory issues and other health problems. The oil industry’s reliance on fossil fuels continues despite these environmental costs because of the high energy density of oil, existing infrastructure, and economic dependency.

Oil is predominantly used to generate energy through combustion, powering transportation, electricity, and industry. Its use releases substantial quantities of CO2—an accelerant of global warming—alongside other pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides, which degrade air quality and impact human health globally. The global economy heavily depends on oil, given its dense energy content and established supply chains. The transportation sector, in particular, remains reliant on petroleum fuels, creating a political and economic environment resistant to rapid change. Governments and industries often prioritize energy security and economic stability, which perpetuates dependence on fossil fuels. Political decisions influence exploration, subsidies, and regulatory standards, affecting the speed and extent of renewable energy adoption.

Transitioning to renewable, environmentally friendly energy sources such as solar or wind would have significant political and economic repercussions. These include potential declines in oil revenues for oil-exporting nations, job losses in fossil fuel industries, and the need for substantial investments in new infrastructure and technology. Politically, shifting away from oil could weaken geopolitical power Dynamics centered around oil-producing countries, fostering a push for more renewable-based international cooperation. Economically, the transition could stimulate growth in green industries, create new job opportunities, and mitigate climate change effects. However, such a transition requires strong political will, policy innovation, and international collaboration to manage the economic challenges and ensure energy accessibility and security during the shift toward sustainable energy systems.
