The fossil fuels are still used to compensate the fluctuations.

Question

BlackTom AI · Accepted Answer

In evaluating the statement, we consider how energy systems manage variability and unpredictability in supply and demand.
One common rationale is that fossil fuels provide dispatchable, controllable power that can quickly compensate for fluctuations in renewable generation or sudden changes in demand. This aligns with the role of gas-fired plants, coal-fired plants, or other fossil-fired units acting as backup or peaking capacity to stabilize the grid when wind, solar, or other sources are variable.
A potential misconception is to assume that fossil fuels are being phased out entirely in modern grids. While there is a strong push toward decarbonization, the immediate balancing needs of the grid often still rely on fossil-fuel generation because it can ramp up or down quickly and is readily available as a controllable resource. This makes the statement plausibly true in many contexts, especially in regions where storage or alternative balancing resources are not yet sufficient.
Conversely, some might argue that with advances in energy storage, demand response, and interconnections, fossil fuels are less essential for fluctuations. While these developments reduce reliance in some areas, the claim that fossil fuels are still used to compensate fluctuations remains accurate in numerous power systems today, though the extent varies by country and technology deployment.
In summary, the statement reflects a widely observed practice: fossil fuels often serve as a reliable backstop to balance intermittent generation and demand swings, even as efforts toward cleaner balancing solutions continue.
