Study Notes
Energy resources are sources from which useful energy can be extracted for human activities, classified into renewable and non-renewable resources. Understanding these classifications helps in planning sustainable energy strategies.
- Renewable Energy Resources — resources that can be replenished naturally within a human timescale. Example: Solar energy, wind energy, and hydroelectric power.
- Non-Renewable Energy Resources — resources that cannot be replenished within a human timescale and will eventually deplete. Example: Fossil fuels like coal, oil, and natural gas.
- Energy Security — the reliable availability of energy sources at an affordable price, considering environmental impacts. Example: A country having diverse energy sources and stable supply chains.
- Long-Term Energy Security — focuses on economic development and meeting environmental needs over decades. Example: Investment in sustainable infrastructure and renewable technologies.
- Short-Term Energy Security — concerns the immediate ability to respond to sudden changes in energy supply or demand. Example: Maintaining grid stability and managing price volatility.
