Terawattituntia

Terawattituntia is the Finnish term for terawatt-hour, an energy unit used to express the amount of energy produced or consumed over a period of time. It refers to one terawatt of continuous power sustained for one hour and is abbreviated as TWh in international usage. In numeric terms, one terawatt-hour equals 10^12 watt-hours, or 3.6 × 10^15 joules. The term terawattituntia is used in Finnish-language contexts to denote this same quantity.

Terawattituntia is a unit of energy, not a rate. It measures how much energy flows over a period, rather than the instantaneous power at a moment. It is commonly employed to describe electricity generation and consumption on national, regional, or global scales. For example, a country’s annual electricity production is often reported in tens of thousands of terawatt-hours.

Conversions and scale: 1 TWh equals 1,000,000 MWh or 1,000 GWh. In joules, it is 3.6 × 10^15 J. Compared with other energy units, a petawatt-hour (PWh) equals 1,000 TWh, while a gigawatt-hour (GWh) equals 0.001 TWh.

Notes: Do not confuse terawatt-hours with terawatts, which denote a unit of power (the rate of energy flow) rather than total energy. Terawatt-hours are particularly useful in reporting long-term energy trends, electricity markets, and national energy statistics.
