Solar panels finally produce more energy than it takes to make them, study finds

Solar energy has a reputation as being a clean energy source but hasn't earned it — at least not up until now. That's because in a darkly ironic truth, the power used to manufacture solar panels still comes mainly from electricity generated by fossil fuels. But a new study from Stanford researchers …
