No they are not. They use energy, a lot of it. They want to run their data centers off of renewable, "carbon-free" energy sources and made some great strides towards that. But they aren't there yet. On top of that, renewables aren't carbon neutral per se, either. And the hardware you put into those things isn't free either. Now you might argue the services google is able to provide with them warrant the environmental costs, but that's another question entirely. And you might argue that google did a lot of things to reduce their footprint (and they did) but it's hardly close to zero, let alone negative.
