Power from the sun
- The sun pours more energy on Earth in an hour than we use in a year.
- Solar 太阳能 power captures some of that free energy.
- It makes no smoke and no CO2 while running.
- There are two main ways to use it: active and passive.
来自太阳的能量
- 太阳在一小时里倾泻到地球上的能量比我们一年用的还多。
- 太阳能(solar)捕捉那免费能量的一部分。
- 它在运行时不产生烟雾也不产生CO2。
- 有两种主要的使用方式:主动式和被动式。
Active solar
- Active 主动式 solar uses equipment to collect and move energy.
- Photovoltaic 光伏 (PV) panels turn sunlight straight into electricity.
- Solar water heaters use pumps to move sun-warmed water.
- These systems have parts, wiring, and sometimes pumps.
主动式太阳能
- 主动式(active)太阳能用设备来收集和移动能量。
- 光伏(photovoltaic,PV)板把阳光直接变成电。
- 太阳能热水器用泵来移动太阳加热的水。
- 这些系统有部件、线路,有时还有泵。
Solar photovoltaic (PV) panels make… · 太阳能光伏(PV)板产生……
Photovoltaic cells turn sunlight straight into electricity, with no burning and no moving parts. · 光伏电池把阳光直接变成电,不燃烧也没有移动部件。
Passive solar
- Passive 被动式 solar uses smart design, with no equipment.
- South-facing windows let winter sun warm a room.
- Thick walls and floors store daytime heat and release it at night.
- Roof overhangs shade the windows in summer.
被动式太阳能
- 被动式(passive)太阳能用巧妙的设计,没有设备。
- 朝南的窗户让冬季的太阳温暖房间。
- 厚墙和地板储存白天的热量,在夜间释放。
- 屋檐在夏天为窗户遮阴。
Active or passive solar? · 主动式还是被动式太阳能?
Sort each example by whether it uses equipment (active) or just smart design (passive). · 按照使用设备(主动式)还是仅靠巧妙的设计(被动式),给每个例子分类。
Passive solar design uses… · 被动式太阳能设计使用……
Passive solar uses clever design — windows, thick walls, overhangs — to catch and hold heat with no devices. · 被动式太阳能用巧妙的设计——窗户、厚墙、屋檐——来捕捉和保持热量,没有设备。
While running, solar power produces no CO2 and no air . · 在运行时,太阳能不产生CO2,也不产生空气。
Solar power makes electricity with zero emissions while it runs — a major clean-energy advantage. · 太阳能在运行时零排放地发电——一个主要的清洁能源优势。
The catch
- Solar only works when the sun shines — it is intermittent 间歇性.
- Output drops at night and on cloudy days.
- Cloudy or high-latitude places get far less.
- To use solar at night, you need batteries to store it.
问题所在
- 太阳能只在太阳照耀时有效——它是间歇性(intermittent)的。
- 输出在夜间和多云的日子下降。
- 多云或高纬度的地方得到的少得多。
- 要在夜间用太阳能,你需要电池来储存它。
A drawback of solar power is that it makes no electricity at night. · 太阳能的一个缺点是它在夜间不发电。
Solar depends on sunlight, so output drops at night and on cloudy days — it is intermittent. · 太阳能取决于阳光,所以在夜间和多云的日子输出下降——它是间歇性的。
Select all · 所有 advantages of solar power. · 选出太阳能的所有优势。
Solar is clean, renewable, and rooftop-ready — but it works far better in sunny places than cloudy or high-latitude ones. · 太阳能干净、可再生、适合屋顶——但它在阳光充足的地方比多云或高纬度的地方效果好得多。
Keep active and passive straight. Active = equipment (PV panels, pumps) that collects or converts solar energy, often into electricity. Passive = design (windows, thick walls, shade) that captures heat with no moving parts. If it has a panel, wire, or pump, it's active; if it's just the shape and materials of the building, it's passive.
把主动式和被动式分清。主动式=设备(PV板、泵),收集或转化太阳能,常常转成电。被动式=设计(窗户、厚墙、遮阴),用没有移动部件的方式捕捉热量。如果它有板、线或泵,就是主动式;如果它只是建筑的形状和材料,就是被动式。
One sunny house:
- On the roof, active PV panels feed electricity to the lights and fridge.
- Inside, big south-facing windows and a thick stone floor are passive — they soak up the sun's warmth all day and release it after dark, with no machine at all.
- Both cut the fuel bill; only one has moving parts.
一座阳光充足的房子:
- 屋顶上,主动式PV板给灯和冰箱供电。
- 屋内,大的朝南窗户和厚石地板是被动式的——它们整天吸收太阳的温暖,天黑后释放,完全没有机器。
- 两者都削减燃料账单;只有一个有移动部件。
Solar power captures the sun's energy with zero emissions while running. Active solar uses equipment — photovoltaic panels for electricity, pumps for hot water. Passive solar uses building design — windows, thick walls, overhangs — with no moving parts. Its main drawback is being intermittent: no power at night or under heavy cloud.
太阳能在运行时零排放地捕捉太阳的能量。主动式太阳能用设备——光伏板发电,泵供热水。被动式太阳能用建筑设计——窗户、厚墙、屋檐——没有移动部件。它的主要缺点是间歇性:夜间或浓云下没有电。
