#CoastalNotes - Heavy rains last week caused the latest in a series of landslides that has cut off a coastal village in Co Kerry, as TheJournal.ie reports.

Only pedestrian access is currently permitted on the Cliff Road to Rossbeigh after a partial collapse of the roadside into the sea on Thursday (17 September).

But the cliff fall is no surprise to locals who have complained for the last two years over increasing erosion caused by various heavy rains and severe storms.

#CoastalNotes - Solutions to deal with the erosion of Ireland's coastline to not have to cost "millions", a geography lecturer tells The Irish Times.

The comments by University College Cork's Dr Max Kozachenko follow a less heartening scenario described by fellow UCC academic Prof Robert Devoy, who said last month that erosion rates - exacerbated by increasingly extreme weather - will soon force Ireland's coastal counties to look "very clinically" at what parts are most worth saving via expensive engineering works.

However, Dr Kozachenko says that such a take-it-or-leave-it solution is "simplistic" when a co-ordinated approach involving coastal monitoring and new approaches to managing the effects of wind and wave action could stem the damage to Ireland's coastline for little expense.

He cites the placing of rock fragments in front of protective rock armouring or concrete walls to scatter waves and dissipate their energy as a cheap but effective option, and also notes the success of offshore artificial reefs in Japan that have had the added benefit of assisting in biodiversity.

#Coasts - Increasing coastal erosion and weathering will soon force Ireland to make hard decisions about what parts of the coastline are too expensive to protect, according to a university professor.

As The Irish Times reports, Prof Robert Devoy of University College Cork says that with erosion rates threatening to jump far beyond the current average of up to 1 metre a year, Ireland's coastal counties would have to look "very clinically" at what parts are most worth concentrating their engineering efforts - expensive measures that simply cannot be afforded for all coastal areas.

The senior lecturer in the UCC Department of Geography says: "We need to assess which bits of the coast are most vulnerable to flooding and erosion and which bits of coast from a heritage viewpoint are important to retain and protect."

This sobering warning comes after Lorna Siggins' commentary on the state of Ireland's coastal marine environment, as six new marine protected areas are set to be enacted in law.

The six sites around the coast earmarked for designation as Special Areas of Conservation were proposed by Heritage Minister Jimmy Deenihan more than a year ago

But as Siggins states: "There’s turbulence ahead, if the State’s approach to fulfilling the habitats directive on land is anything to go by."

Aside from the "inconsistencies, poor communication and lack of stakeholder engagement" of the likes that have undermined bog conservation efforts, there's also the "survival of the fittest" attitude among the fishing fleet engendered by uneven implementation of the Common Fisheries Policy to contend with.

And according to Siggins, even the reformed CFP spearheaded by Marine Minister Simon Coveney will do "little to protect sensitive spawning grounds".

ESB’s 2040 strategy Driven to Make a Difference: Net Zero by 2040 sets out a clear roadmap for ESB to achieve net zero emissions by 2040. 

ESB will develop and connect renewable energy to decarbonise the electricity system by 2040. ESB will invest in the development of new renewable generation, including onshore and offshore wind and solar, and will significantly increase the amount of renewable generation connected to our electricity networks.

ESB will:

  • Deliver more than a fivefold increase in our renewable generation portfolio to 5,000MW.
  • Reduce carbon intensity of generation fleet from 414 to 140gCO2/kWh by 2030.
  • Decarbonise 63% of our generation output by 2030 and 100% by 2040 (up from c20% now).

Offshore wind

ESB know the importance of offshore wind in tackling climate change and delivering net zero. Ireland has a unique capability given its prime location to take advantage of the potential of offshore wind. ESB are working hard to develop offshore wind projects for the benefit of everyone across society in Ireland and the UK. This includes ongoing engagement with marine users and local communities so ESB can deliver these significant projects.

Offshore wind will play a major role globally in our fight against climate change. It will help to replace energy generated by burning fossil fuels with that from a clean, safe and secure renewable energy source. Ireland’s geographic location on the exposed edge of the Atlantic presents us with a significant opportunity to generate electricity from wind – both offshore and onshore.

Power from onshore wind farms currently provide over one-third of Ireland’s electricity needs. But, whilst its marine area is many times the size of its landmass, Ireland’s offshore wind potential is only starting to be realised. ESB have a coastline stretching over 3,000km but only one operational offshore wind farm – Arklow Bank, with a capacity of 25 MW. In contrast, Belgium’s coastline is only 63km long, but it has already developed more than 2,000 MW of offshore wind. In Great Britain, with a coastline four times the length of ours, offshore wind generation now equates to over 440 Arklow Banks, with an installed capacity of 11,0000 MW as of late 2021.

The Irish Government's target to install 5,000 MW of offshore wind capacity in our maritime area by 2030 is set out in the Climate Action Plan 2021. It also has the objective to source 80% of Ireland’s electricity needs from renewables by the same year. In line with this, ESB is applying its professional and proven engineering expertise to the challenges set within the Climate Action Plan.

ESB are committed to playing a strong role in developing Ireland’s offshore wind potential for the benefit of the people of Ireland. This will be done in consultation with marine users and local communities, and with due care for the marine environment.
