Which statement best describes a major environmental disadvantage of using fossil fuels for electricity generation?

Q: How do I try a free CXC Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which statement best describes a major environmental disadvantage of using fossil fuels for electricity generation?

Accepted Answer

They release carbon dioxide which contributes to the enhanced greenhouse effect — Burning fossil fuels releases carbon dioxide (CO₂), a greenhouse gas that enhances the greenhouse effect and contributes to global warming — this is the primary environmental criticism of fossil fuels. Radioactive waste is associated with nuclear power. Large land use and bird disruption apply mainly to wind farms. Weather dependence is a limitation of renewable sources like solar and wind, not fossil fuels.

Answer

They produce radioactive waste that lasts thousands of years

Answer

They release carbon dioxide which contributes to the enhanced greenhouse effect

Answer

They depend on weather conditions and are therefore unreliable

Answer

They require large areas of land and disrupt bird migration
