Show answer and explanation

Answer: B. It can reduce emissions from electricity used for lighting

Solar-powered streetlights use energy from sunlight instead of electricity generated using fossil fuels. Therefore, replacing half the streetlights can reduce greenhouse gas emissions from lighting. However, factory emissions remain unchanged because their electricity consumption has not decreased. This is an example of climate mitigation.
