Most better-off countries treat electricity as something that if not a right, is at least a strong public-policy priority: something that we believe everyone should have access to. At least, to the extent that the country as a whole is developed enough for it to be feasible. And yes, that includes subsidizing it to improve access; rural electrification in the United States and Canada (at least) was massively subsidized.
But public policy priorities are very different than rights. A public policy priority can be modified or eliminated as circumstances dictate. In theory, anyway, a human right is absolute.
That's why people who campaign for positive rights make a grave error, IMO. It cheapens the entire concept.
