Kütustest

Kütustest is an Estonian word form derived from the noun kütus, meaning fuel. In usage, kütustest represents a plural or combined form that appears in contexts referring to multiple fuels or to aspects related to fuels. It is commonly encountered in technical, economic, and policy texts discussing energy sources, fuel types, and the composition of fuel supplies.

In Estonian grammar, kütustest is one of the inflected forms of kütus and is typically found in phrases that describe fuels in a general sense or as part of a larger specification. It can appear in statements about the origins, categories, or characteristics of fuels, including both fossil fuels (such as oil, coal, and natural gas) and renewable or alternative fuels (such as biomass-derived fuels and biogas). Because of its plural sense, kütustest is suited to discussions about “fuels” as a group rather than a single type.

In practice, the term is most often seen in technical writing, energy statistics, and regulatory texts where lists or comparisons of fuel types are presented. For example, a report might analyze emissions from kütustest or outline changes in the cost of kütustest over time. As a grammatical form, its exact use depends on the sentence structure and the case required by Estonian syntax. See also kütus, kütuste hinnad, energy policy.
