In a recent letter to The Economist, Robert Kennedy Jr. said that bitcoin mining is a powerful new tool to support renewable energy-intensive power grids. He pointed out that while electricity networks are facing pressure from manufacturing, electric vehicles and data centers, the electricity consumption patterns of bitcoin mining are different from traditional electricity consumption and can have a positive impact on the grid. Kennedy stressed that unlike facilities such as data centers, bitcoin mining farms only operate when electricity is cheap and abundant. When electricity scarcity causes prices to rise, the mine will reduce electricity consumption within seconds. In addition, Kennedy pointed out that bitcoin miners are actively involved in demand response projects, allowing grid operators to control their electricity consumption to stabilize the grid. The participation of bitcoin miners in these projects helps to bid in open markets and reduce the cost of electricity for consumers.
