A solar-powered street light is an example of what?

Answer and explanation

Correct answer: Green technology

A solar-powered street light uses photovoltaic panels to convert sunlight into electrical energy, usually storing some energy in a battery for use after sunset. Because sunlight is a renewable energy source, the system can reduce dependence on conventional fossil-fuel-based electricity and may lower operating emissions. It also provides useful public lighting when designed, installed, and maintained properly. Therefore, option D is correct because a device that applies renewable energy to meet a practical need is an example of green technology. It is not inherently fuel wastage, noise pollution, or water pollution, although all equipment should still be managed responsibly at the end of its useful life.
