Where energy comes from
- Everything we do uses energy — light, heat, transport, factories.
- That energy comes from natural resources.
- Some of those resources refill; some run out.
- This is the first big split in studying energy.
能量从哪里来
- 我们做的每件事都用能量——照明、供暖、运输、工厂。
- 那些能量来自自然资源。
- 有些资源会补充;有些会耗尽。
- 这是研究能源的第一个大区分。
Renewable resources
- A renewable 可再生 resource is refilled by nature as fast as we use it.
- Sunlight arrives every day, wind keeps blowing, rivers keep flowing.
- We can use them forever without running out.
- Solar, wind, hydro, geothermal, and biomass are all renewable.
可再生资源
- 一种可再生(renewable)资源被大自然补充的速度和我们使用它一样快。
- 阳光每天到来,风一直吹,河流一直流。
- 我们能永远使用它们而不耗尽。
- 太阳能、风能、水力、地热和生物质都是可再生的。
A renewable resource is one that… · 一种可再生资源是……
A renewable resource is refilled by nature on a human timescale — sunlight, wind, and flowing water keep coming. · 一种可再生资源在人类的时间尺度上由大自然补充——阳光、风和流水一直到来。
Nonrenewable resources
- A nonrenewable 不可再生 resource exists in a fixed amount and runs out.
- Coal, oil, and natural gas are fossil fuels 化石燃料 — buried ancient life.
- They took millions of years to form, so we cannot make more.
- Nuclear fuel (uranium) is also nonrenewable — the ore is limited.
不可再生资源
- 一种不可再生(nonrenewable)资源以固定的量存在,会耗尽。
- 煤、石油和天然气是化石燃料(fossil fuels)——埋藏的古代生命。
- 它们花了数百万年形成,所以我们无法制造更多。
- 核燃料(铀)也是不可再生的——矿石有限。
Renewable or nonrenewable? · 可再生还是不可再生?
Sort each energy source by whether nature refills it or it runs out. · 按照大自然是否补充它,或它会耗尽,给每种能源分类。
Which is a nonrenewable resource? · 哪个是不可再生资源?
Coal took millions of years to form, so once burned it is gone. Wind, sun, and water are renewable. · 煤花了数百万年形成,所以一旦烧掉就没了。风、太阳和水是可再生的。
Coal, oil, and natural gas are the three ____ fuels. · 煤、石油和天然气是三种____燃料。
Fossil fuels formed from ancient buried life; they are nonrenewable. · 化石燃料由古代埋藏的生命形成;它们是不可再生的。
Why the split matters
- Nonrenewable fuels supply most of the world's energy today.
- But they will run low, and burning them pollutes the air.
- Renewable sources are cleaner and never run out.
- The big challenge is shifting from nonrenewable to renewable energy.
为什么这个区分重要
- 不可再生燃料今天供应世界上大部分能量。
- 但它们会变少,而且燃烧它们污染空气。
- 可再生能源更干净且永不耗尽。
- 最大的挑战是从不可再生能源转向可再生能源。
Solar and wind energy will run out within a few years of heavy use. · 太阳能和风能在大量使用几年内就会耗尽。
Sunlight and wind keep arriving no matter how much we use — that is what makes them renewable. · 无论我们用多少,阳光和风都持续到来——这正是它们可再生的原因。
Select all · 所有 renewable energy sources. · 选出所有可再生能源。
Solar, wind, and hydropower are renewable. Coal is a nonrenewable fossil fuel. · 太阳能、风能和水力是可再生的。煤是不可再生的化石燃料。
"Renewable" is about the rate of refill, not about being clean. A renewable source can still cause harm (a dam floods land; biomass burning releases smoke). And "nonrenewable" does not mean instantly gone — there is coal left, but it is finite and will run out. Judge each source by both: does it refill, and what does it cost?
"可再生"是关于补充的速度,不是关于干净。一种可再生能源仍然能造成伤害(一座大坝淹没土地;燃烧生物质释放烟雾)。而"不可再生"不意味着立即没了——还有煤,但它有限且会耗尽。用两点判断每种能源:它补充吗,它的代价是什么?
Two power stations:
- One burns coal dug from a mine. When the coal seam is empty, that energy is gone forever — and the smoke pollutes the air.
- The other spins turbines with wind. Tomorrow the wind blows again, and the day after. The fuel never runs out and makes no smoke.
- Same electricity; one source is renewable, the other is not.
两座发电站:
- 一座燃烧从矿里挖的煤。当煤层空了,那个能量永远没了——而且烟雾污染空气。
- 另一座用风转动涡轮机。明天风再吹,后天也吹。燃料永不耗尽,不产生烟雾。
- 同样的电;一种能源是可再生的,另一种不是。
A renewable resource is refilled by nature as fast as we use it (solar, wind, hydro, geothermal, biomass). A nonrenewable resource exists in a fixed amount and runs out — the fossil fuels (coal, oil, natural gas) and nuclear fuel. Fossil fuels supply most energy today but are finite and polluting; the shift to renewables is the central energy challenge.
一种可再生资源被大自然补充的速度和我们使用它一样快(太阳能、风能、水力、地热、生物质)。一种不可再生资源以固定的量存在,会耗尽——化石燃料(煤、石油、天然气)和核燃料。化石燃料今天供应大部分能量,但它们有限且污染;转向可再生能源是核心的能源挑战。
