Significant exported minerals include , , , and . and (LNG) are also significant resource exports. Extractive resources make up 86% of all exports, has their high value has enabled the country to generally run current account surpluses. The biggest mine is a private gold mine on , which is followed by the state-run , and.

In , operates in a flywheel storage power plant with 200 flywheels of 25 kWh capacity and 100 kW of power. Ganged together this gives 5 MWh capacity and 20 MW of power. The units operate at a peak speed at 15,000 rpm. The rotor flywheel consists of wound fibers which are filled with resin. The installation is intended primarily for frequency c.

While a (BJT) can be simplistically thought of as two diodes with a shared terminal (anode for the PNP variety), the transistor polarity is usually expressed based on the prevalence of in the parts of the device: for the regions where the charge flow is primarily due to the electrons (free due to the presence of ), and for the regions where the flow is mostly due to (available spaces for additional electrons.

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196.

Compressed-air-energy storage (CAES) is a way to for later use using . At a scale, energy generated during periods of low demand can be released during periods. The first utility-scale CAES project was in the Huntorf power plant in , and is still operational as of 2024 . The Huntorf plant was initially de.
