One of the biggest challenges of renewable energy is the unpredictability of production. Unlike nuclear energy, which is always available, solar and wind energy are dependent on natural elements. This leads to strong price fluctuations throughout the day.

When the sun is at its peak, we enjoy an abundance of energy. This leads to an oversupply on the market and pushes energy prices down to very low, sometimes even negative, values. It is a sunny side of renewable energy, literally and figuratively. But when the sun sets and the wind dies down, we experience a shortage of energy, resulting in rising prices.

These fluctuations in energy production and prices raise an essential question: how can we address this imbalance and stabilize our energy grid?

To address these challenges, a two-pronged approach is required. First, we need to ensure that we produce enough energy when the sun is shining, in order to meet demand during periods with less sunlight, such as the winter. However, this can lead to an oversupply of energy in the summer, when there is a lot of energy being produced and prices are low.
