The rise of renewable energies on the peninsula
As the world progresses to a cleaner energy model, the Iberian Peninsula begins to experience significant change. Renewable energy sources, such as solar, wind and hydroelectric energy, are taking center stage in electrical production. In fact, in certain time slots, these sources are responsible for most of the electricity consumed, thus eliminating the emission of carbon dioxide during their generation.
A path full of challenges for Catalonia
However, Catalonia is in a difficult position on this journey to sustainability. Currently, only 19% of its electricity comes from renewable sources, a percentage that reveals the urgent need to accelerate energy transition in this region.
The intermittent of green energies
One of the great obstacles that face renewable energy is its intermittent nature. Unlike traditional sources such as gas or coal, which can constantly generate electricity, the sun and wind are not always available. This means that during night or in poor days, fossil fuels are needed to ensure energy supply.
Innovations to ensure supply
In order to face this intermittent, it is essential to implement new technologies and strategies. The flexibility of demand, such as lighting appliances during hours of solar production, can be a solution. In addition, lithium batteries, despite their price fall, are still under development to guarantee their long -term viability.
The key role of reversible hydroelectric power plants
One of the most promising systems is reversible hydroelectric power plants. These installations function as a water battery, where excess renewable energy is used to pump water in a upper raft. When energy production decreases, water is dropped to generate electricity, offering an effective solution to maintain the stability of the electric system.
Economic and environmental benefits
In addition to their stabilizing function, these plants provide economic benefits. They can consume electricity during the cheapest hours, even when it is free, and generate energy during the hours of maximum demand. This not only helps to stabilize electricity prices, but also avoids the waste of renewable energy surplus.
A sustainable future
With this mechanism, reversible hydroelectric power plants already represent up to 5% of the electricity consumed during rush hours in the peninsula. Collaboration between energy and institution experts is essential to advance this energy transition. Next week, this topic will continue to be explored, with the participation of several professionals in the energy sector.
