Climate change hampers renewable energy production

energías renovables

The increase in global temperature represents a challenge for the production of renewable energy.

One of the consequences of climate change is the increase in global temperatures. To counteract this, governments have been committed to the development of renewable energy projects for decades. However, rising temperatures are becoming an obstacle to the production of clean energy.

Heat waves and photovoltaic panels

The intensity of heat waves affects cells and modules, reducing their performance in the face of rising temperatures. Contrary to what one might think, solar panels do not generate more energy when the thermometer soars. One study estimated the loss in efficiency at 0.45% for every 1° increase in temperature. In addition, there is the cost of ensuring that the panels are cooled to prevent overheating.

On the other hand, pollution also contributes to this decrease in production. This was revealed in a study that showed that particles from human pollution affect solar panels. Dirt from dust accumulates on their surface, blocking light and causing energy losses.

What happens if it doesn’t rain?

Changes in rainfall patterns are causing periods of drought and soil erosion, as well as heavy rainfall and flooding. All of this ultimately alters the flow and course of rivers.

This daunting scenario will affect the dams where hydroelectric power is generated. If this sustainable resource runs out of raw material, there is no point in minimising its environmental impact. In addition, rising temperatures may cause water levels in reservoirs to evaporate, altering the power generated in hydropower plants. This is a huge problem for the renewable energy.

Consequences for wind energy

Changes in wind speed and direction have a negative impact on wind energy. This is because turbines are designed to operate efficiently for a certain range of speed and orientation. In addition, the increase in global temperature decreases the power generated, as the warm air is less dense.

While green energy is necessary to promote a sustainable energy transition, such energy sources face their own challenges arising from the excessive use of fossil fuels.
