Ireland Just Set a New Wind Energy Record

A whopping 70% of the island’s electricity was generated by wind turbines on Wednesday.

The “green” puns pretty much write themselves. On Wednesday, Ireland set an all-time high for wind output on the Irish grid at 4,629 megawatts, Green Collective reports.

By midnight Thursday, wind had accounted for a smidgen over 70% of Ireland’s total electricity demands for the day.

In 2022, Ireland ranked third in the world, alongside Uruguay, when it came to its share of electricity generated by wind power: 33%. Only perennial wind leader Denmark, which generated a whopping 55% of its electricity from gusty weather last year, and surging Lithuania (38%), edged it out.

It’s not just — forgive me — luck, either. According to the COP28 Global Offshore Wind Update, a new report from industry consultancy ERM published yesterday, only two countries out of the 19 that have 2030 offshore wind targets are expected to hit them: Ireland being one, and Poland being the other, Recharge writes. Most of its current wind capacity, however, is from onshore wind farms.

Ireland’s wind generation information is easily accessible from EirGrid, making the region a favorite case study among energy nerds — including the creators of the charming Irish Energy Bot (which later evolved into Green Collective). Earlier this year, the account also celebrated wind generation exceeding “all-island electricity demand” in Ireland for the first time, during overnight hours and Storm Agnes-related gusts. According to EuroNews, such trends have translated into significant savings:

[As of September, the] latest figures mean that in total, Irish wind farms provided 32% of the country’s power over the first eight months of 2023. Electricity prices on days with the most wind power dropped by an average of 5% to €88.34 [$95] per megawatt-hour.

On days when Ireland relied almost entirely on fossil fuels, that cost rose to €123.07 [$132] per megawatt-hour.

With numbers like that, who needs a crummy old pot of gold?

The Best Idea From Today’s Big Oil Hearing

It was always a fantasy to think that the Senate Committee on the Budget’s hearing on oil disinformation would actually be about oil disinformation. It was still shocking, though, how far off the rails things ran.

The hearing concerned a report released Tuesday by the committee along with Democrats in the House documenting “the extensive efforts undertaken by fossil fuel companies to deceive the public and investors about their knowledge of the effects of their products on climate change and to undermine efforts to curb greenhouse gas emissions.” This builds on the already extensive literature documenting the fossil fuel industry’s deliberate dissemination of lies about climate change and its role in causing it, including the 2010 book Merchants of Doubt and a 2015 Pulitzer Prize-nominated series from Inside Climate News on Exxon’s climate denial PR machine. But more, of course, is more.

Air Quality Data for the Rich

Wealth bias shows up in the strangest places — including, according to new research, PurpleAir sensor data.

Everyone loves a public good, and one of the classic examples is clean air. When I breathe in clean air, no one else gets any less of it, and you can’t exclude people from enjoying it.

But how do we know whether the air we’re breathing is clean? And is that information a public good?

It’s Never Too Early to Start Thinking About COP

The United Nations’ climate summit in Dubai ended last December with a mad dash to lock in a location for this year’s gathering. Which is how we wound up with yet another petrostate — Azerbaijan — as the host.

On Thursday at a climate conference in Berlin, Azerbaijan’s minister of ecology and natural resources and COP29’s President-Designate Mukhtar Babayev outlined his vision for the November get-together. “Our previous promises now need to be delivered, not re-interpreted. Fulfilled, not re-negotiated,” he told participants in the Petersberg Climate Dialogue, according to a transcript of his prepared remarks. “Everyone has a duty to make sure their actions match their words.”
