Net metering helps me, it doesn't help the grid reduce costs. I sell my energy for exactly what the grid sells it for, they earn nothing. But the grid still has to make my electricity with fossil fuels in the winter to give it back to me. It still has to have energy on standby for rainy days in summer. It still needs to pay year-round overhead and staffing for powerplants, even when the energy isn't needed like summer days when I make enough for 4 or 5 houses. My having panels is great for me, but bad for my neighbors electric rates.
