Spain, Portugal’s energy interruption is linked to the lack of stability of the renewable energy network

Last Monday was a difficult day for citizens Spain and Portugal.

Both countries were subjected to a period of electricity for hours, some say it is the worst such event in the living memory. What they did not get was a clear explanation of how all this happened. At least not from the government.

The potential perpetrators who have been presented to the front include excessive use of renewable energy such as solar energy or wind, electronic attacks, human error, harsh weather, and government policy. However, it appears to be a set of factors instead of one factor, as experts say.

“This was not ordinary black,” Daniel Laccal, the chief economist of the Madrid investment company in Madrid, told Fox Business. “The phones did not succeed; there was no 4G phone.” In addition, some people were stuck in trains or elevators and were unable to access the Internet.

The huge European power outages on the faults of solar energy plants

One of the first allegations about what happened was the so -called “vibration in the atmosphere”. This happens when there are rapid changes in the weather that changes the fluctuations in the upper electrical network lines, according to Professor Gianchong Woo at Cardiff University focusing on multi -party energy systems. He is also an expert in the electricity network, among other things.

However, Wu was not convinced that “vibration” caused the power outage.

Woo wrote in an article: “I am not aware of the harsh weather conditions in Spain today (my daughter on a school trip in Spain, and she told me that the weather was really nice), so I am not sure whether this is the real reason.” Scientific Information Center On the same day, such as power outages.

Another early voltage to direct the prosecution included that the power outage was due to green energy such as solar energy and wind. This was quickly rejected by the Prime Minister in Spain Pedro SanchezThose who claimed that the people who spread this interpretation were “lying”.

“None of the government’s excuses has any meaning,” says Lusal.

Here where things become more complicated. While renewable energy sources did not disrupt the power generation on its own, it was part of the mixture that made it happen.

The background of power outages begins with the efforts made to increase the use of renewable energy sources. “There is a step throughout Europe to reduce fossil fuels and nuclear use,” Ben Habib, Chairman of the Great British Political Action Committee, told Fox Business.

Nuclear energy is subject to a revival in the United States

In 2011, renewed energy in Spain fueled 31 % of electricity, according to Statista data. The share increased to 57 % last year, which means a significant decrease in the joint use of fossil and nuclear fuel. This was part of Spain’s goal to approach clear carbon emissions.

In addition, Spain got its clear desire. For the first time, they achieved this goal on April 16 on the entire network. However, this achievement was both successful and problematic. In fact, the effect of the beating that would lead to the latter’s blackout.

Increased production of massive electricity from wind and solar energy sent energy prices. On January 20, electricity on the immediate market in Spain cost 145 euros ($ 165) per MB hour, according to the new trading economy data. This fell to 11 euros (about $ 12) by March 21.

In turn, the low prices mean that Spain Nuclear power plants Lusal says if he can no longer pay their taxes when producing electricity. The result witnessed that nuclear power plants temporarily stop operation, and can from natural gas stations to generate electricity.

However, the absence of the near natural gas or nuclear energy also created instability in the network. Laccal said that much renewable energy is unreliable (the sun does not always shine, and winds are not always present.) He added that there were warnings about the potential instability on the network.

However, the lack of stability was ultimately on April 28 with a clear electricity network.

Habib said: “The principle of transition to clean energy is worth, but the way to do this is to use fossil and nuclear fuels and wait until we turn to renewable energy sources in this work.”
