Option 1 -> The passage does not mention anything about renewable energy producing higher quality energy.
Option 2 -> This contradicts the passage, which states "The initial cost of setting up a renewable energy infrastructure is high."
Option 3 -> The passage explicitly states that "Unlike fossil fuels, which are finite and release harmful greenhouse gases when burned, renewable energy sources... are sustainable and environmentally friendly," indicating they don't emit harmful gases.
Option 4 -> This is incorrect as the passage mentions "some technologies, like solar and wind, depend on weather conditions."
Hence, Option 3 -> Renewable energy sources are environmentally friendly precisely because they don't release harmful greenhouse gases when used, unlike fossil fuels that emit carbon and other pollutants. This minimal emission characteristic is what makes them sustainable alternatives in combating climate change -> correct
