uusiutuneet

Uusiutuneet is a Finnish adjective derived from the verb uusiutua, meaning to renew or regenerate. It is commonly used as the past participle form to modify plural nouns and can describe items that have undergone renewal. In everyday language, uusiutuneet literally means renewed or regenerated, but in technical contexts it is closely associated with the concept of renewability.

In energy terminology, the phrase uusiutuvat energialähteet, meaning renewable energy sources, is standard. The opposite category consists of non-renewable or finite energy sources such as fossil fuels. The term emphasizes that the resource is replenishable within a human timescale, allowing long-term sustainable use.

Representative renewable energy sources include solar power (aurinkosähkö), wind power (tuulivoima), hydro power (vesivoima), biomass energy (bioenergia), and geothermal energy (geoterminen energia). These sources are characterized by natural replenishment and lower greenhouse gas emissions over their life cycles compared with fossil fuels.

Policy and statistical frameworks in Finland and internationally track the share of uusiutuvat energianlähteet in electricity generation, heating, and transport. Growth in the sector is linked to energy security, climate objectives, and technological advances in storage and grid integration.
