In the early 2000s, people were buzzing about the idea that we might soon run out of oil. Fast forward a decade, and the conversation shifted to “There’s oil everywhere!” So, what’s the real story? Today, the world produces about 93 million barrels of oil each day, and there’s still over a trillion barrels left underground. While we’ve tapped into most of the easy-to-reach oil, new technologies like horizontal drilling and hydraulic fracturing are helping us access more. But with the environmental impact of fossil fuels, we have to wonder: When will we finally move away from oil?
How much oil we use and its environmental effects often depend on the availability of alternative energy sources. Let’s take a trip back in time. In the 17th century, the United States had 820 million acres of untouched forest. But after years of using wood for energy, only 138 million acres remained. By the mid-1800s, we hit “peak wood.” Luckily, we found coal, which seemed like a cleaner option back then. Similarly, in 1846, whale oil was all the rage for lamps, and we almost drove whales to extinction. It wasn’t just the dwindling supply that saved them; it was the discovery of kerosene, a new lamp fuel made from oil.
Throughout history, solving one energy problem often led to another. While we once thought using tools defined us as humans, it turns out our ability to harness energy sets us apart. How a society uses energy is a big part of its identity. Humans first used thermal energy, then kinetic energy, and the invention of the steam engine allowed us to convert one form of energy to another. This sparked the Industrial Revolution, a major turning point in history. As societies progress, they tend to use more energy. The 20th century showed this trend with increased energy use for a growing population and various applications.
There’s been a shift from wood to coal to oil, and now to renewable energy sources, which have grown significantly in the past decade. We’re getting more energy per unit of CO2 than ever before. While there’s a push to reduce carbon emissions, this journey started long ago. Despite improvements in efficiency and reduced fossil fuel use over the past decade, total energy consumption has increased, leading to higher emissions than 40 years ago, with fossil fuels still being the main energy source.
U.S. energy use mirrors global trends, showing that energy challenges are shared worldwide. Unfortunately, predictions suggest that our energy sources won’t change much in the next 20 years, raising concerns about climate change. Historically, energy transitions involved newer, cleaner sources replacing older, dirtier ones. However, with most of our energy technologies dating back to the 19th century, developing new energy sources has become less common. As CO2 levels continue to rise, waiting for peak oil may not be an option. For the first time, we might need to create our own peak.
Create a timeline that traces the history of energy use from the 17th century to the present. Include key events, such as the transition from wood to coal, the discovery of oil, and the rise of renewable energy. Use visuals and brief descriptions to highlight how each energy source impacted society and the environment. This will help you understand the evolution of energy use and its implications.
Participate in a classroom debate on the pros and cons of fossil fuels versus renewable energy sources. Research both sides of the argument, focusing on environmental impact, economic factors, and energy efficiency. This activity will enhance your critical thinking and public speaking skills while deepening your understanding of current energy challenges.
Conduct an analysis of your household’s energy consumption over a month. Identify the main sources of energy and calculate the carbon footprint. Propose strategies to reduce energy use and transition to more sustainable practices. This hands-on activity will make you more aware of personal energy consumption and its broader environmental impact.
Work in groups to design and build a simple model of a renewable energy source, such as a wind turbine or solar panel. Present your model to the class, explaining how it works and its potential benefits. This project encourages creativity and teamwork while providing practical insights into renewable energy technologies.
Invite a local energy expert or environmental scientist to speak about the future of energy and the role of technology in shaping energy trends. Prepare questions in advance to engage in a meaningful discussion. This activity will offer you a real-world perspective on energy issues and inspire you to think about potential solutions.

[MUSIC] In the early 2000s, discussions about the end of the oil age were prevalent. “No more oil!” Yet, here we are a decade later, with claims of “Oil everywhere! We’ll never run out of oil!” So, what’s the reality? Currently, the world produces around 93 million barrels of oil daily, with over a trillion barrels still in the Earth’s crust. While we have extracted most of the easily accessible oil, advancements in technologies like horizontal drilling and hydraulic fracturing are allowing us to access more reserves. However, considering the environmental impact of fossil fuels, we must ask: When will we move away from oil?
Historically, the amount of oil we extract and its impact on the environment largely depends on the availability of alternative energy sources. [MUSIC] In the 17th century, there were 820 million acres of virgin forest in the United States, but after centuries of using wood for energy, that number dropped to just 138 million. At some point in the mid-1800s, we reached “peak wood.” Fortunately, we found an alternative fuel that seemed environmentally friendly at the time: coal. Similarly, in 1846, due to the popularity of whale oil as a lamp fuel, we reached “peak whale.” Our reliance on whale oil nearly drove these creatures to extinction.
However, it wasn’t just the dwindling supply that saved the whales; it was the discovery of kerosene, a new lamp fuel derived from oil. The history of energy often involves solving one problem by introducing another. While we once thought tool use defined humanity, we later recognized that our ability to manipulate energy is a unique characteristic.
How a society utilizes energy is a key aspect of its identity. Humans first harnessed thermal energy and later kinetic energy, but the invention of the steam engine allowed for the conversion of one form of energy to another. This capability led to the Industrial Revolution, a significant turning point. Generally, as societies advance, their energy consumption increases, and the 20th century exemplifies this trend with more energy used for a growing population and diverse applications.
However, there’s also a shift from wood to coal to oil to renewables, with renewable energy sources growing significantly in the past decade. We are now obtaining more energy per unit of CO2 than ever before. Although there is a focus on reducing carbon emissions, we have been on this path for quite some time. Despite improvements in efficiency and reduced fossil fuel consumption over the past decade, total energy consumption has increased, leading to higher emissions than four decades ago, with fossil fuels still dominating energy sources.
U.S. energy use aligns closely with global trends, indicating that energy challenges are shared across the world. Unfortunately, projections suggest that our energy sources will not change significantly in the next two decades, raising concerns about climate change. Historically, energy transitions have involved newer, cleaner sources replacing older, dirtier ones. However, with most of our energy technologies originating in the 19th century, the development of new energy sources has become less common. As CO2 levels continue to rise, waiting for peak oil may not be a viable option. For the first time, we may need to create our own peak.
