Intermittency in renewable energy refers to the characteristic of certain renewable energy sources to not generate power continuously. Solar power is intermittent because it only produces electricity when the sun is shining, and its output varies with cloud cover and the time of day. Wind power is also intermittent, as it relies on the presence and strength of wind, which can fluctuate significantly. Hydropower, while generally more reliable, can also experience intermittency due to seasonal variations in rainfall and river flow. Geothermal energy, which harnesses heat from the Earth's interior, and biomass energy, which uses organic matter, are generally considered non-intermittent or baseload power sources.

The challenge of intermittency is that it can make it difficult to match electricity supply with demand in real-time. This requires grid operators to have backup power sources available, often from fossil fuels, to fill the gaps when renewable generation is low. Solutions to mitigate intermittency include energy storage technologies, such as batteries, pumped hydro storage, and thermal storage. Grid modernization, including smart grids and demand-side management, also plays a crucial role in balancing supply and demand. Diversifying the renewable energy mix across different regions and technologies can also help smooth out overall generation patterns, as different sources may be intermittent at different times.
