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?

Former President Trump wants to know: Would you rather be electrocuted or eaten by a shark?

On Sunday, during a rally in Las Vegas, the Republican nominee floated the question for what is at least the second time this campaign season (an odd choice, perhaps, given that Nevada is hardly shark territory, and therefore his supporters there are unlikely to have given the question much thought).

Tornado Alley Is Moving East

New research finally sheds some light on what the heck is happening.

If hurricanes, wildfires, heat, and floods are the Big Four of extreme weather in America, then tornadoes are perhaps the equivalent of the National Bowling League.

That’s not for lack of fatalities — tornadoes kill more people annually than hurricanes, per the 30-year average — nor for their lack of star power (see: The Wizard of Oz, Sharknado, Twister, and my most highly anticipated movie of the year, Twisters). But when it comes to the study of extreme weather, robust, detailed data on tornadic supercells has been described as “largely absent,” at least compared to the scholarship on their more popular meteorological counterparts.

A Swiss Army Knife for Clean Energy

These can really do it all — almost.

Before and for the first year or so after the Inflation Reduction Act, clean energy in the United States was largely developed under the aegis of two tax credits: the Production Tax Credit, which primarily useful for wind power, and the Investment Tax Credit, which is primarily used for solar power. (The actual eligibility for each tax credit for each technology has changed various times over the years, but that’s the gist.)

Starting in 2025, however, and lasting (absent any change in the law) through at least 2032, that tax credit regime will be made “technology neutral.” Goodbye, existing credits with their limited applicability. Hello, new tax credits that apply to “any clean energy facility that achieves net-zero greenhouse gas emissions,” according to a release issued Wednesday by the Treasury Department.

“For too long, the U.S. solar and wind markets have been hampered by uncertainty due to the on-again-off-again nature of key tax credits,” Treasury Secretary Janet Yellen said on a call with reporters. “Periods of indecision and the credits being repeatedly allowed to elect to lapse made it too difficult for companies to plan and invest in clean energy projects.”
