One of the biggest myths about renewable energies is their alleged lack of reliability. However, California, a pioneer in this field, proves otherwise. A recent study highlights that during certain periods of last year, renewable energies covered 100% of the state’s electricity needs for durations of up to 10 hours on 98 days, thanks to battery support. While challenges such as wildfires continue, California maintains its transition to a greener energy grid, with about half of the electricity coming from renewable sources such as hydropower, wind, and solar. This ambitious journey faces rising electricity rates, not because of renewables, but partly due to natural disasters and imposed obligations.
The Reliability of Renewable Energies in California
The transition to renewable energies is often tainted by misconceptions, one of the most notable being their alleged unreliability. However, recent studies conducted in California have demonstrated that these energy sources can be both reliable and sustainable in meeting the energy needs of millions of people. In 2023, California achieved a remarkable feat by supplying up to 100% of its electricity needs through renewable energies for 98 days out of a 116-day period, illustrating their potential when properly implemented and managed.
Furthermore, California continues to prove that batteries play a crucial role in stabilizing the electric grid. They recharge during the day, primarily through solar energy, and then release this energy during peak demand periods, typically in the evening. This strategy has allowed the Californian grid to maintain perfect balance without resorting to fossil fuels, which puts an end to the idea that only fossil fuels can ensure uninterrupted production.

Economy and Costs Associated with Clean Energies
One might expect that the shift to renewable energies would result in lower costs for consumers. This is not always the case, especially in California where electricity costs remain high. This disparity is explained by other external factors such as the costs related to wildfire prevention, which are unfortunately common in the region. Thus, while the implementation of renewable energies can lead to cost savings, the additional expenses associated with infrastructure and safety measures sometimes drives prices up for Californian consumers.
Interestingly, other U.S. states, such as Iowa, where renewables constitute a large part of the energy supply, have managed to keep electricity prices lower. This observation highlights the fact that renewables can truly reduce costs, but it depends on the local context and the policies implemented.

The Role of Technological Advancements
Advancements in energy storage batteries and their integration into the Californian electrical grid are essential for maximizing the use of renewable resources. As technology evolves, the storage capacity and durability of batteries increase, allowing for the efficient accumulation and use of energy, even during periods of low solar or wind production. Moreover, the initiative to combine various energy sources such as offshore wind, geothermal, and hydropower ensures continuous and resilient energy production.
These innovations are not limited to storage. The implementation of new solutions for electrical infrastructures helps reduce service interruptions and optimize the use of available resources. Thus, while the transition to a fully renewable model has its challenges, California shows that investments in green technologies are worthwhile for building a sustainable energy future.
