On April 28, a massive blackout affected around 55 million people in Spain and Portugal.
4月28日，西班牙與葡萄牙發生大規模停電，約有5,500萬人受影響。
affect(v.)影響
Data from the electricity grid around that time showed major changes in energy flow.
當時電網的數據顯示能量流動出現劇烈變化。
big data大數據grid(n.)電網、網格系統
However, as of April 30, the exact cause of the blackout remained unclear.
然而，截至4月30日，停電的確切原因仍不清楚。

Early reports suggested that a cyberattack or human error might have been responsible.
初步報導指出，這次停電可能是由網路攻擊或人為疏失造成的。
initial(adj.)初步的cyberattack(n.)網路攻擊human error人為疏失
However, both the Spanish and Portuguese governments have ruled out these possibilities.
然而，西班牙與葡萄牙政府皆已排除這些可能性。
rule out排除、認為～不可能
In addition, energy experts say the blackout was not caused by too much sun or wind.
此外，能源專家也表示，太陽能或風能過載並不是造成此次停電的原因。

According to The Guardian, one possible explanation for the incident is the structure of the electricity grid in both countries.
根據《衛報》的報導，這次事件的一個可能原因是兩國電網的結構。
plausible(adj.)貌似真實(或可信)的
Spain and Portugal are leading the EU’s shift toward renewable energy, with around 80% of their electricity coming from solar and wind power.
西班牙與葡萄牙在歐盟推動再生能源轉型方面處於領先地位，約有80%的電力來自太陽能與風能。
shift(n.)(v.)轉移、轉變renewable(adj.)可再生的、可更新的renewable energy可再生能源
Although this reduces their reliance on fossil fuels, the systems used to deliver renewable energy may have contributed to the blackout.
雖然這減少了對化石燃料的依賴，但用來傳輸再生能源的系統本身可能也導致了停電。
reliance(n.)依賴;仰賴=dependencefossil fuels化石燃料contribute to導致、促成=lead to=bring about
David Brayshaw from the University of Reading explained that grids powered by renewable energy can be more sensitive to sudden disruptions than those using fossil fuels or nuclear power.
雷丁大學的戴維‧布雷肖解釋說，相較於使用化石燃料或核能的電網，再生能源電網對突發狀況更為敏感。
be sensitive to...對～敏感的be susceptible to容易受到～的影響的disrupt(v.)、disruption(n.)打斷;中斷;擾亂
As a result, even if the energy source wasn’t the issue, the grid itself may have made the blackout more serious and widespread.
因此，即便能源本身不是問題，電網系統也可能讓這次停電變得更加嚴重與廣泛。

Pratheeksha Ramadas from Rystad Energy agrees.
來自Rystad Energy的普拉蒂克莎‧拉瑪達斯也表示認同。
She noted that changes in how solar and wind energy are added to the grid can affect the entire power system.
她指出，太陽能與風能併入電網時的變化可能影響整個電力系統。
She recommends investing in more stable grids that can handle renewable energy.
她建議應投資於更穩定的電網，以因應再生能源的需求。
recommend(v.)建議=propose=suggeststable(adj.)穩定的=steady
She also believes that the results of this investigation will be of interest for other countries working to build reliable and secure energy systems based on renewable sources.
她也認為，這次調查結果將對其他致力於建立可靠且安全再生能源系統的國家，具有重要參考價值。
be of interest for sb.令某人感興趣的、對某人來說有參考價值的reliable(adj.)可靠的、可信賴的
