energy reserves
Backup power sources
Energy reserves are stored sources of energy available for future use.
The term applies at multiple scales: a nation's energy reserves include untapped oil, natural gas, and coal deposits; a power grid maintains reserves to meet sudden demand spikes; a body's energy reserves are stored fat and glycogen that fuel activity when food intake falls short.
The country is investing in renewable energy to reduce dependence on finite fossil fuel reserves.
