What is the green benefit of an LED bulb?

Correct answer: It uses less electricity

An LED bulb produces useful light with less electrical energy than many older incandescent or conventional lighting options. Because it is energy efficient, using an LED can reduce electricity consumption for the same lighting need. Where electricity is generated by burning fossil fuels, lower consumption can also reduce associated greenhouse-gas emissions. Therefore, option D is the green benefit. Using more water, producing more smoke, or generating more solid waste does not describe the main environmental advantage of an LED bulb. The central concept is efficient energy use and the resulting conservation of resources.
