The top three energy sources in the world, based on global consumption, are:
### 1. **Oil**
- **Overview**: Oil remains the largest energy source globally, playing a crucial role in transportation, industry, and heating. It is refined into various products such as gasoline, diesel, and jet fuel.
- **Usage**: Despite efforts to transition to renewable energy, oil accounts for a significant portion of global energy consumption due to its high energy density and established infrastructure.
### 2. **Coal**
- **Overview**: Coal is the second most consumed energy source worldwide. It is predominantly used for electricity generation and in industrial processes like steel production.
- **Environmental Impact**: Coal is also one of the largest sources of CO2 emissions, contributing significantly to global climate change. Its use has been declining in some regions due to environmental concerns, but it remains a dominant energy source in others, especially in Asia.
### 3. **Natural Gas**
- **Overview**: Natural gas is the third most consumed energy source. It is used for electricity generation, heating, and as a feedstock for chemical products like fertilizers.
- **Growth**: Natural gas consumption has been increasing, partly due to its lower carbon emissions compared to coal and oil. It is often seen as a "bridge fuel" in the transition towards a lower-carbon energy future.
These energy sources currently dominate the global energy landscape, although the share of renewable energy sources like wind, solar, and hydropower is growing rapidly as countries aim to reduce greenhouse gas emissions and combat climate change.
