您的流媒体播放器使用了多少能量？

流媒体电视设备（如 Roku 或 Chromecast）已插入并随时准备就绪。当您的电视关闭时，它会消耗更少的电量，但是流媒体设备呢？他们使用多少能量？

有许多不同形状和大小的流媒体设备。有些是较大的“机顶盒”，而另一些是小型的“流媒体棒”。功耗因设备而异。让我们看看哪些使用最多。

流媒体设备的世界是广阔的。大多数生产此类设备的公司都有多种选择。我们挑选了一些您可能拥有的最常见的流媒体设备。

另一件需要考虑的事情是您使用设备做什么。从 Netflix 流式传输 4K HDR 电影比观看 YouTube 视频消耗更多的能量。不可能衡量你可以用流媒体设备做的每一件不同的事情，但我试图得到一个很好的一般衡量标准。

我使用智能插头测量了 Chromecast Ultra、Chromecast with Google TV 和 Roku Ultra 的瓦数。对于 Apple TV 和 Fire TV，我能够找到信息来源。（“~”字符表示大概数量。）

Device	TV On	Idle
Apple TV 4K	3.03-5.58w	0.30w
Chromecast Ultra	1.5-2.0w	1.5w
Fire TV 4K	~4w	~1w
Chromecast with Google TV	~1.0-3.0w	1.0w
Roku Ultra	~3.0-4.5w	3.0w

There’s some pretty interesting data here. Surprisingly, the Chromecast Ultra uses about the same amount of energy as the Chromecast with Google TV—even a bit more while idle. The Google TV has a full-blown operating system, whereas the Ultra is just a dongle.

The Apple TV 4K and Roku Ultra are very comparable as the “biggest” devices of the bunch, but Apple’s uses very little power while idle. The Fire TV 4K was also comparable to the bigger devices.

How Much Does it Cost?

Let’s put some dollar signs on all these numbers. We’ll use an electricity rate of $0.18 per kilowatt-hour (kWh), four hours of active use, and 20 hours of idle time. Here’s how it breaks down (keep in mind these are estimates):

Apple TV 4K: Around $1.44 per year.
Chromecast Ultra: Around $2.41 per year.
Fire TV 4K: Around $2.36 per year.
Chromecast with Google TV: Around $1.83 per year.
Roku Ultra: Around $4.87 per year.

Due to the higher idle power usage, the Roku Ultra is far and away the most expensive of the bunch. That’s also why the Apple TV 4K is the cheapest, since its idle power usage is very low. Idle power usage is very important for devices you don’t use all the time.

Now, is around $5 per year to keep your Roku plugged in all the time a big deal? Probably not. That’s less than $0.50 per month. Still, it’s interesting to see how much power our daily devices are using.
