Core Meaning

  • Pinyin (with tone marks): nénghào
  • Part of Speech: Noun
  • HSK Level: HSK 5
  • Concise Definition: The consumption of energy or power.
  • In a Nutshell: 能耗 (nénghào) is a formal and technical term for 'energy consumption.' It's not the word you'd use for flipping a light switch, but rather for measuring the total energy used by a machine, a factory, a city, or a whole country. Think of it as the word you'd see in a government report about environmental goals, on a sticker on your new air conditioner detailing its efficiency, or in a news article about the tech industry's power-hungry data centers.

Character Breakdown

  • 能 (néng): This character's most common meaning is “can” or “ability.” However, it is also the root character for “energy” as seen in the word 能量 (néngliàng). In 能耗, it specifically refers to energy.
  • 耗 (hào): This character means “to consume,” “to use up,” or “to expend.” It often carries a sense of gradual depletion over time.
  • The two characters literally combine to mean “energy consume,” forming a direct and precise noun for the concept of “energy consumption.”

Cultural Context and Significance

  • The significance of 能耗 is not rooted in ancient philosophy but in modern China's rapid economic development and its consequences. For decades, China's growth was fueled by energy-intensive heavy industry. Today, the term is at the heart of the nation's push for a more sustainable and high-tech economy.
  • National Policy: 能耗 is a keyword in China's Five-Year Plans and national strategies. The government implements strict “dual control” (双控 - shuāngkòng) policies to limit both the total amount of energy consumption (能耗总量) and its intensity (能耗强度 - energy consumed per unit of GDP). This has a direct impact on which industries are encouraged and which are restricted.
  • Comparison to “Energy Consumption” in the West: While the literal meaning is the same, the cultural weight is different. In Western countries, “energy consumption” is often framed around individual responsibility (turning off lights, buying an electric car) and corporate ESG (Environmental, Social, and Governance) initiatives. In China, while individual action exists, the discourse around 能耗 is dominated by top-down, state-driven industrial policy and national security. Controlling 能耗 is seen as a crucial lever for achieving national goals, from environmental protection to technological self-sufficiency.

Practical Usage in Modern China

  • 能耗 is a formal term, most often encountered in written contexts or formal discussions.
  • Government & Economics: It's ubiquitous in news reports, economic analyses, and government documents discussing environmental targets, industrial upgrades, and GDP quality. Ex: “China aims to reduce its 能耗 per unit of GDP.”
  • Industry & Manufacturing: Factories and businesses are categorized by their 能耗. A “high energy consumption enterprise” (高能耗企业) might face stricter regulations or be targeted for technological upgrades.
  • Technology: The tech world frequently discusses the 能耗 of data centers, cryptocurrency mining (which was banned in China largely due to its massive 能耗), and AI model training.
  • Consumer Products: You will see 能耗 on the “China Energy Label” (中国能效标识 - Zhōngguó néngxiào biāozhì) on appliances like air conditioners, refrigerators, and washing machines, which grades the product on its energy consumption.

Nuances and Common Mistakes

  • Formal vs. Informal: The most common mistake is using 能耗 in casual conversation. It sounds overly technical and unnatural. For daily situations, use more specific and colloquial terms.
    • Incorrect: 我的手机能耗太快了。(Wǒ de shǒujī nénghào tài kuài le.) - “My phone's energy consumption is too fast.”
    • Correct: 我的手机太费电了。(Wǒ de shǒujī tài fèidiàn le.) - “My phone uses up battery too quickly.” (Lit: “is too electricity-consuming”)
  • Energy vs. Electricity: 能耗 is a broad term for all forms of energy (electricity, coal, natural gas, oil). If you are talking specifically about electricity, the term 用电量 (yòngdiànliàng - amount of electricity consumed) is more precise.
    • Example: Don't say “这个月的能耗是300度” (This month's energy consumption was 300 units/kWh). Instead, say “这个月的用电量是300度” (This month's electricity consumption was 300 kWh).
  • Noun, not a Verb: 能耗 is a noun. To talk about the action of consuming energy, you would use a verb like 消耗 (xiāohào) or 使用 (shǐyòng) with 能源 (néngyuán).
    • Example: This machine consumes a lot of energy.
    • Incorrect: 这个机器能耗很多能源。
    • Correct: 这个机器消耗很多能源。(Zhège jīqì xiāohào hěn duō néngyuán.)
