Berikut di bawah ini yang tidak termasuk sumber energi yang dapat diperbaharui adalah ….
Correct Answer
A. Gas alam
Explanation
Gas alam is not a renewable energy source because it is a fossil fuel that is formed over millions of years from the remains of plants and animals. Once it is extracted and burned for energy, it cannot be replaced or replenished in a short period of time. On the other hand, sources like hewan (animals), tumbuhan (plants), and air (wind, solar) are considered renewable because they can be naturally replenished within a human lifespan.
