Is it better to use solar energy or water heater in rural areas of Yexian County, Pingdingshan, Henan Province?

Each has its own advantages, especially solar energy may save electricity, but the water show is more serious for the local area, so it may have a great long-term impact. Personally, I think it is best to broadcast live with a water heater. Pay attention to safety when using the water heater, especially when using electricity. So personal feeling. For the sake of safety, it is best to use solar energy.
