California's energy generation and consumption rely on a diverse mix of sources. As of recent data, the top three sources of California’s energy generation are:
### 1. **Natural Gas**
- **Share**: Around 40%-45% of California’s in-state electricity generation.
- **Details**: Natural gas power plants have been the leading source of electricity in California for several decades. Although the state has been transitioning towards renewable energy, natural gas still plays a vital role in meeting energy demand, especially during peak hours or when renewable sources are not sufficient.
### 2. **Renewable Energy**
- **Share**: Approximately 30%-35%.
- **Breakdown**:
- **Solar**: Leading the renewable category, solar energy alone contributes around 15%-20% of California’s electricity generation.
- **Wind**: Contributes about 7%-10%.
- **Geothermal, Biomass, and Small Hydropower**: These contribute the remaining portion of renewable energy generation.
- **Details**: California has aggressively expanded its renewable energy portfolio in recent years, aiming to reduce greenhouse gas emissions and combat climate change.
### 3. **Hydropower (Large)**
- **Share**: Roughly 5%-15%, depending on water availability (varies annually).
- **Details**: Large hydroelectric power has historically been a significant source of electricity in California, but its share can fluctuate due to drought conditions and water resource management.
Other sources include nuclear energy (specifically the Diablo Canyon plant), which still contributes a small percentage, and imports from neighboring states, which also play a role in meeting California’s electricity demand.
