In the most recent century, the primary sources of energy have indeed included natural gas, coal, and also oil. Additionally, while these fossil fuels have played a significant role in energy production, there has been a growing focus on renewable sources such as solar, wind, hydroelectric, and geothermal energy, especially in the past few decades as concerns about climate change and sustainability have increased.
If you’re looking for a more comprehensive overview of energy sources over the last century, here’s a summarized breakdown:
-
Fossil Fuels:
- Coal: Historically one of the main sources of energy, especially during the industrial revolution.
- Oil: Became dominant in the 20th century, significantly powering transportation and electricity generation.
- Natural Gas: Gained prominence in the late 20th century and is now widely used for heating, electricity production, and as a cleaner alternative to oil and coal.
-
Nuclear Energy:
- Provided a significant source of electricity generation since the mid-20th century.
-
Renewable Energy:
- Hydropower: One of the oldest sources of renewable energy used for electricity generation.
- Wind and Solar: Gained traction in the late 20th and early 21st centuries, with substantial growth due to technological advancements and decreasing costs.
The energy landscape continues to evolve as new technologies emerge and the focus shifts toward sustainability.
