How much of a problem is this? Is this a merely theoretical possibility, is it actively being exploited? What are the information leakage risks as compared to e.g. internet advertising, NSA surveillance, malware?

How much electricity does this use?

Yes, it is actually a quite problem because this is something you cannot counter with encryption or other similar means.

The power usage is on average 100mA.
