Critics say energy-saving technology is a threat to rare species already suffering from low numbers

The Royal Society for the Protection of Birds has completed construction of a 100 metre wind turbine at its headquarters despite warnings they are a deadly danger to some birds and bats.
The turbine will save an estimated 800 tonnes of carbon emissions a year as it generates the equivalent of half the electricity the RSPB uses across its 127 sites.
Critics of the technology warn turbines pose a threat to birds, particularly rare species which are already suffering from low numbers or migratory species, as well as to bats.
The Scottish Gamekeepers' Association (SGA) has previously claimed wind turbines are killing killed more birds of prey than deliberate poisoning or shooting.
But RSPB's turbine got the go-ahead as an article in the journal Nature claimed they killed far fewer birds than than other human causes such as buildings, cars, power lines, pesticides and pet cats.
