Baseload matters. The power we use in our homes 24/7/365 comes from many sources, including power plants that convert fossil fuels like coal and natural gas into electricity, nuclear power plants, and renewable energy sources like wind turbines, solar farms, and hydroelectric dams. The electricity supplied from these sources is categorized as baseload, peaking, and intermittent.
The majority of the electricity we use comes from baseload power sources. These always-available power sources are designed to constantly generate large amounts of electricity to ensure the reliable supply of energy we need 24/7/365. As you may expect, these power sources are not designed to ramp up or down quickly in response to a sudden change in electricity demand.
When the demand for electricity spikes suddenly, peaking power plants, usually fueled by natural gas, are designed to quickly power up and come online to meet the sudden demand. These sources run for a short time to meet the increased demand, then quickly power down as the need wanes.
Renewable power sources such as wind and solar are increasingly used to supply the call for cleaner energy. However, these power sources are unreliable and must depend on Mother Nature for fuel. Solar panels are unable to generate enough electricity on cloudy days, and wind turbines will only spin when the right amount of wind speed is present, not too little and not too much.
Batteries are a promising technology to provide storage for renewable energy when there is excess generation to be used at a later time when there is not. Battery storage is an evolving technology but faces its own obstacles, such as production and lithium mining.
Those who are concerned about climate change may wonder why electric suppliers aren’t rushing to replace fossil fuel power with more renewables. The answer is there simply would not be enough power available to meet the needs of today, much less the increasing electric demand of tomorrow. An energy policy that forces early retirement of fossil-fuel plants only exacerbates the energy supply problem and pushes the grid closer to being unable to provide reliable electricity 24/7/365.
