More than 80% of serious or fatal cycling collisions occur in daylight and on straight roads, new data from Ireland shows.

The @RSAIreland latest data rebuts claims that cyclists should be made to wear hi-vis clothing at all times!

Good article 👇

Councillor Burke's dystopian vision for Ireland

[TheJournal.ie @thejournal_ie]

A motion passed by Clare County Council has called for making high-vis jackets mandatory for pedestrians and cyclists.

It has been criticised by the Irish Cycling Campaign, which said it would push some people back towards the car.

@thejournal_ie Just a normal day in Councillor Burke's dystopia

@JoeBrad29403090 @XEnergyIreland @kbdolly69 The final report 2026 debunked the idea that high levels of renewables were a primary factor in the blackout, pointing instead to insufficient voltage control.

Integrating high levels of renewables is challenging but manageable using modern technology like grid forming inverters

[Kevin Sheedy @KevSheedy]

@XEnergyIreland @kbdolly69 Wind + solar + storage can supply ~85% the future electricity demand. That's a lot of fossil fuels not burnt.

The remaining ~15% of energy will come from some combination of interconnectors, biofuels, LDES and gas. It's unclear yet what the exact mix will be.

[Kevin Sheedy @KevSheedy]

@kbdolly69 @XEnergyIreland Paid for out of the savings we make not spending billions on gas.

Wind + solar + storage is cheaper than expensive gas.

[Kevin Sheedy @KevSheedy]

@kbdolly69 @XEnergyIreland Since 2020, Ireland has seen a rapid growth in grid batteries, from 0 to 1 GWh in 5 years:

Turlough Hill: 292 MW, 1.8 GWh
Grid batteries: 965 MW, 1 GWh
2030 Projection: ~5,000 MW, ~13.5 GWh

Plus all the home and EV batteries that will store the wind energy.

[Kevin Sheedy @KevSheedy]

@XEnergyIreland Wind still provided 34% of Ireland's electricity yesterday, despite the momentary lull.

I reckon spending billions on wind, storage and grid is cheaper than spending billions on expensive gas.

@Deiscirt @pulse_carbon Next they’ll be saying we’ll depend on rain for our water. What about when it doesn’t rain?!? Madness I tell you

[Kevin Sheedy @KevSheedy]

@PopeSeneca @IrishTimes Global stock index funds return on average 7-8% per year, so it's good for the investor and good for government. Win win.

This seems like a really sensible piece of tax reform, making a complicated tax system (exit tax) much simpler.

[Kevin Sheedy @KevSheedy]

@Pastey_n Ireland has been happily importing nuclear energy from the UK for many years and will now have access to even more from France. While also exporting Irish wind energy.

[Kevin Sheedy @KevSheedy]

@Ben_Scallan Nuclear twice as expensive as renewables so at best it could help with decarbonising the difficult last 15% of electricity.

At worst, we could spend 20 years and vast amounts of money building something that is no longer needed when it's complete.

March sees almost 50% of electricity generated by renewables with new records for grid scale solar

[Kevin Sheedy @KevSheedy]

@garrettmullan Isn't it being implemented gradually to allow businesses and workers time to adapt? Eventually reaching 14%

[Kevin Sheedy @KevSheedy]

@garrettmullan If you want to make additional pension contributions, can't you just setup a private pension and do so?

Also, isn't it normal for schemes like this to launch in a simple format and then have the bells & whistles added later after the initial issues have been fixed?

@XEnergyIreland @AoifeMFoley @EnergyCloud_org @RTERadio1 @UtilityregCRU With plans to scale up to 8GWh:

@XEnergyIreland @AoifeMFoley @EnergyCloud_org @RTERadio1 @UtilityregCRU Some good progress recently on the 100 hour Iron-Air battery project from Form Energy and FutureEnergy Ireland. 10MW / 1,000MWh. First of its kind I believe.

[Kevin Sheedy @KevSheedy]

@XEnergyIreland Nuclear could absolutely do this. I'd worry the high cost, ~15 year setup time and politics could be prohibitive.

Unclear what the most economical solution will be.

I'm fascinated by the innovation in advance geothermal and LDES with Iron air batteries, which could play a role.
