If we want surplus power, if we want a strong grid, if we want cheap power, if we want to enable the ability to quite literally waste solar power on inefficient processes (including things like industrial processes that produce less CO2 or generating hydrogen or methane as long term energy storage), we have to get the government to make it happen
