Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ископаемое топливо' when a simpler term like 'нефть, газ, уголь' is more natural in context.
- Note that 'fuel' alone ('топливо') is broader; the compound term is specific.
Common Mistakes
- Using as a plural only ('fossil fuelses').
- Confusing with 'fossil' alone.
- Misspelling as 'fosil fuel'.

FAQ
Frequently Asked Questions
No, nuclear power uses uranium, which is a mineral, not a fuel formed from the remains of ancient organisms.
They form over millions of years from decayed organic matter, so they are being consumed far faster than they can be naturally replenished.
When burned, they release carbon dioxide, a greenhouse gas that traps heat in the atmosphere and drives climate change.
Yes, commonly in compound adjectives like 'fossil-fuel industry' or 'fossil-fuel emissions'. It can also be used in hyphenated verb forms (e.g., fossil-fuelled).
