Since 2007, the use of coal for electricity generation has generally been in decline, while the use of renewables has been on the rise. Electricity generation from nuclear had remained relatively flat over the last two decades but has experienced a slight decline in recent years. In 2022, net generation of electricity from renewables reached 0.91 billion megawatt-hours, topping both coal and nuclear (0.83 and 0.77 billion megawatt-hours, respectively). In 2022, renewables accounted for about 21% of all net generation of electricity.
