• Pinyin (with tone marks): diànlì
• Part of Speech: Noun
• HSK Level: HSK 4
• Concise Definition: Electric power as a utility, industry, or large-scale energy source.
• In a Nutshell: 电力 (diànlì) is the standard, slightly more formal term for “electric power.” Think of it as the electricity that flows through the national grid to power cities, industries, and homes. While you might say your phone is out of “电 (diàn)”, you would discuss the “电力 (diànlì)” industry or a city's “电力 (diànlì)” supply. It refers to electricity as a system and a resource.

• 电 (diàn): This character is a combination of 雨 (yǔ - rain) and申 (shēn), which originally depicted a lightning bolt. Thus, 电 originally meant “lightning” and has evolved to mean all things “electric.”
• 力 (lì): This character is a pictograph of a plow or a muscular arm, symbolizing “strength,” “force,” or “power.”
• Together, 电力 (diànlì) literally translates to “electric strength” or “electric force,” a logical and descriptive term for the power that drives the modern world.

The concept of 电力 (diànlì) is deeply tied to China's modern identity and its narrative of national rejuvenation. For much of the 20th century, a stable power supply was a luxury. The rapid expansion and modernization of China's power grid (电网 - diànwǎng) in recent decades is a massive source of national pride and a tangible symbol of the country's development. Unlike the West, where electrification was a slower process spanning many generations, China's electrification was incredibly compressed. Many people alive today remember a time without reliable electricity. This makes the arrival of stable 电力 a profound marker of progress that transformed daily life, enabling everything from basic lighting to the country's manufacturing and tech booms. Massive state-led projects like the Three Gorges Dam (三峡大坝 - Sānxiá Dàbà) are celebrated not just as engineering marvels but as testaments to the nation's ability to harness nature to provide 电力 for its people. Therefore, discussing 电力 in China often goes beyond a simple utility; it touches on themes of national strength, technological advancement, and the state's role in improving citizens' lives.

电力 (diànlì) is used in more formal, technical, or large-scale contexts.

• In Industry and Government: This is where the term is most common. You'll hear it in news reports about the economy, government planning documents, and in business contexts.

The most common mistake for learners is confusing 电力 (diànlì) with the more common and general word 电 (diàn).

• 电 (diàn): Refers to the “stuff” itself—electricity. It's used in everyday, tangible situations.
  • Correct: 我的手机没电了。(Wǒ de shǒujī méi diàn le.) - My phone is out of battery.
  • Correct: 请帮我交一下电费。(Qǐng bāng wǒ jiāo yīxià diànfèi.) - Please help me pay the electricity bill.
  • Correct: 小心，有电！(Xiǎoxīn, yǒu diàn!) - Be careful, it's live! (There's electricity!)
• 电力 (diànlì): Refers to the “system” or “resource”—electric power. It's more abstract and formal.
• Common Mistake Example:
  • Incorrect: 我的手机没有电力了。(Wǒ de shǒujī méiyǒu diànlì le.)
  • Why it's wrong: This sounds overly formal and strange, like saying “My phone has no access to the electric power utility.” The simple, natural way is to say it's out of 电 (diàn).

Think of it this way: You charge your phone with 电 (diàn), which is delivered to your house by the 电力 (diànlì) company through the 电力 grid.
