Huh? The main reason heat pumps are being pushed is because they are extremely efficient, not as some kind of sacrifice that we are doing to protect the grid. There is no better option if we are moving away from gas at home.
The only competitive alternative is gas powered heating. However, I believe it’s more energy efficient to use natural gas for electricity generation and use heat pumps for heating rather than piping gas to people’s homes and burning it there. The exception is when it’s so cold that heat pumps do not perform well (although modern heat pumps can work in very cold situations)
