Net Metering and Solar Energy

Net metering is a billing mechanism that allows consumers with rooftop solar panels to send excess electricity back to the grid and receive credits for that energy. It encourages households and small consumers to install solar panels by making solar energy economically viable. The policy allows consumers to offset their electricity consumption with the power they generate. Options (b), (c), and (d) are unrelated to net metering. Net metering specifically promotes distributed solar energy generation at the household level by incentivizing private solar installations.
