- High extraction and production costs
Facts and Statistics about Nonrenewable Energy Consumption
- Fossil fuels account for over 80% of global energy consumption.
- The United States is the world’s largest consumer of nonrenewable energy.
- The burning of fossil fuels is a major contributor to greenhouse gas emissions.
Renewable Energy
Renewable energy refers to energy sources that can be naturally replenished on a human timescale. These sources are derived from ongoing natural processes and are virtually inexhaustible.
Examples of Renewable Energy Sources
- Solar energy
- Wind energy
- Hydropower
- Geothermal energy
- Biomass energy
Advantages of Renewable Energy
- Sustainable and environmentally friendly
- Reduced greenhouse gas emissions
- Decentralized and locally accessible
Disadvantages of Renewable Energy

- Land use requirements
Facts and Statistics about Renewable Energy Production
- Renewable energy accounts for over 25% of global electricity generation.
- Solar and wind power are the fastest-growing renewable energy sources.
- The International Energy Agency (IEA) predicts that renewable energy will account for over 50% of global energy supply by 2050.
Comparison of Nonrenewable and Renewable Energy
| Characteristic | Nonrenewable Energy | Renewable Energy |
|---|---|---|
| Availability | Finite | Virtually inexhaustible |
| Reliability | Reliable and consistent | Intermittent and variable |
| Environmental impact | Significant pollution and greenhouse gas emissions | Minimal pollution and low carbon footprint |
| Cost | Lower upfront costs, but higher long-term costs | Higher upfront costs, but lower long-term costs |
Key Differences between Nonrenewable and Renewable Energy
The key differences between nonrenewable and renewable energy lie in their availability, reliability, environmental impact, and cost. Nonrenewable energy sources are finite and have a limited supply, while renewable energy sources are naturally replenished and virtually inexhaustible. Nonrenewable energy sources are reliable and consistent, but they have a significant environmental impact due to pollution and greenhouse gas emissions.
Renewable energy sources are intermittent and variable, but they have a minimal environmental impact and low carbon footprint. The upfront costs of renewable energy are higher than nonrenewable energy, but the long-term costs are lower.
