The offshore windfarm at Berwick Bank is predicted to kill more than 4,000 birds in its first year alone – among them gannets, puffins and kittiwakes, writes Ashley Davies

Lev Parikian paints a vivid picture of the gannets of the Bass Rock and the impact that avian flu has had on their numbers (Country diary, 31 August). There’s another threat, though, and it’s one that puts some supporters of renewable energy like me in a novel situation: protesting against the construction of a windfarm.

Berwick Bank will be one of the biggest offshore windfarms in the world – a few kilometres from the Bass. This is perilously close, and the RSPB has calculated that it will kill more than 4,000 seabirds in its first year alone, among them gannets, puffins and endangered kittiwakes.

Chief of nuclear watchdog says secret Assad-era facility would have been able to produce fissile material

A nearly complete nuclear reactor built secretly during the rule of the toppled Syrian leader Bashar al-Assad would have been able to produce fissile material for possible use in nuclear weapons, the chief of the UN nuclear watchdog has revealed.

Inspectors from the International Atomic Energy Agency (IAEA) last month visited two sites, one in Deir ez-Zor and a second in an undisclosed location identified to them by Syrian authorities.

Datacentres should generate their own power and control their emissions, writes Richard Lamming, while Michael McClelland says we should reduce our digital communication. Plus a letter from Malcolm Fraser

The case of future datacentres demanding more electricity than the entire United Kingdom (Two planned datacentres will have higher UK carbon emissions than ExxonMobil, analysis finds, 25 August) is an example of corporates transferring their problems to society and the electorate. This must not be allowed to happen.

One solution would be to make each datacentre responsible for generating all its own electricity and for reducing its CO₂ emissions to zero. These installations will have vast areas of roofing and car parks that could be covered in solar panels, space for wind generation and battery storage, and for emissions scrubbers.

A financial model that could cut the cost of installing solar panels for many homeowners is welcomed by Alexis Abramson

The UK proposal to use “solar bonds” to make rooftop solar more affordable is a smart solution to a fundamental problem: the rising cost of capital (Cut cost of loans for solar panels on UK homes, ministers urged, 21 August).

A household that can pay for solar upfront saves money from day one. For everyone else, high-interest financing can consume much of those savings and ultimately deter people from installing the technology. A solar bond structure changes that equation: investors receive a modest, guaranteed return, and homeowners get access to cheaper capital. Because the loan is attached to the property rather than the individual, there’s no issue if the person moves.

Colin Hines says Andy Burnham’s focus should be on drastically cutting fossil fuel use in a way that reduces bills and generates secure jobs

It is hardly surprising that many who were optimistic and supportive of Andy Burnham becoming prime minister, but who also prioritised tackling climate chaos, are becoming increasingly unsure about him, given his tardiness in emphasising this threat as an overriding policy objective (Labour ‘could lose up to 50 seats’ to Greens if new drilling in North Sea approved, 19 August).

One of the problems he faces is that the political debate around energy is obsessed with relatively short-term fossil fuel supplies. Instead, the focus should be on drastically and rapidly cutting fossil fuel use in a way that reduces bills and generates secure jobs through a devolved energy programme for every postcode.
