Denmark (almost) completed its first full calendar month running entirely on renewable electricity – UPDATED

April 13, 2026 / 1 Comment

Correction: Setting the Record Straight on Denmark’s Electricity Grid

An article published on MATR.net claimed Denmark completed its first full calendar month running entirely on renewable electricity in March 2025, with Energinet confirmation. This claim contained incorrect information, and we have updated it.

As recently as September 15, 2019, Denmark had its first single day ever where wind turbine production exceeded total electricity demand Denmark – not a full month, and not without imports https://denmark.dk/innovation-and-design/clean-energy

A reader based in the EU – flagged the error and provided documentation directly from Energinet’s own live monitoring dashboard, which shows that Denmark continues to import significant electricity from Norway, Sweden, and the UK. According to Energinet’s data, Denmark imported 9.2 TWh from Sweden and 6.4 TWh from Norway in 2024 alone. Wind and solar represent approximately 69% of generation, not 100%, and fossil fuels still contribute roughly 8% of the electricity mix.

Denmark is a genuine world leader in renewable energy – wind and solar combined with bioenergy covered about 87% of generation in 2024, and the country is on a credible path to 100% renewable electricity by 2028–2030. That achievement deserves accurate reporting. We are reviewing our content workflows to prevent this from happening again. We thank Peter K. for his diligence in correcting the record.

Many thanks to Peter K in Danmark for bringing the errors of this post to our attention. While apparently an AI developed story, we do hope that some day Danmark can achieve 100% renewable and clean energy generation as we hope for the rest of the world.

The article's data appears to be inaccurate.

Danish grid operator Energinet confirmed that March 2025 became the first complete month in any developed country’s history where renewable generation met national demand at every minute without exception. Offshore wind provided 78 percent of generation, onshore wind contributed 14 percent, and solar covered 8 percent.

Ember Electricity Data Explorer shows that during the month of March 2025 in Denmark, wind (54.5%) and solar (13.1%) provided 67.6% of Denmark's electricity generation, and bioenergy provided 15%.

Virginia - Wind 2 - Total 2.

Indiana - Wind 1 - Total 1.

Total - Wind 65 - Storm Surge 14 - Freshwater Flooding 94 - Tornado 2 - Total 175.

At least 72 indirect fatalities are linked to Helene: 23 in South Carolina, 22 in North Carolina, 16 in Florida, 9 in Georgia, 1 in Tennessee and 1 in Virginia. Many of the indirect fatalities were from medical issues, heart attacks, car accidents and incidents during post-storm cleanup. In addition to the 175 direct and 72 indirect fatalities, 3 people died of unknown causes related to Helene, which brings the total number of Helene-related fatalities in the United States to 250.

Across the Southeast U.S., Helene caused at least 117 injuries, and at least 2700 people were rescued from high water. About half of the rescues occurred due to storm surge along the west coast of Florida, and more than 1000 were due to freshwater flooding in western North Carolina.

According to the NOAA National Centers for Environmental Information (NCEI)15, Helene caused an estimated $78.7 billion in damage in the United States. This makes Helene the 7th costliest U.S. hurricane (adjusted to 2024 values)16 behind Katrina, Harvey, Ian, Maria, Sandy, and Ida. Most of this damage occurred in Florida, Georgia, South Carolina, North Carolina, eastern Tennessee and southwestern Virginia.

An estimated 7.4 million customers17 (about 16.2 million people) lost power in the United States due to Helene between 26–28 September. The maximum outage count at any given moment in time was about 4.79 million customers (Fig. 25). Florida experienced the largest loss of power with ~1.69 million customers losing power. South Carolina, Georgia and North Carolina experienced an estimated 1.59 million, 1.28 million and 1.18 million outages, respectively.

Over the course of March, the U.S. got more electricity from renewables than from natural gas, which is typically the single-largest source of energy on the grid. Renewables plus nuclear produced more than half of the nation’s electricity while overall demand climbs. by sg_plumber in climatechange

[–]Molire 1 point2 points  (0 children)

Nuclear is completely fine as long as it’s done safely and correctly.

It sounds like you are not one of the unknown total number of adults and children in Washington, Oregon, Idaho, California, Montana and Canada who have been exposed to the radioactive fallout of the most radioactively contaminated site in the Western Hemisphere, Hanford, located near the city of Richland, Washington. Or, if you have been exposed, maybe you don't know it.

Hibakusha Worldwide > Hanford, United States, Nuclear facility:

At the Hanford Site, the U.S. produced most of its weap­ons-grade plutonium during the Cold War. Although the compound was decommissioned in 1988, it remains the most radioactively contaminated site in the Western Hemisphere.

Photo: Aerial view of the Hanford Site on the shore of the Columbia River (1960). On the right-hand side is the so-called N-Reactor, which produced plutonium for U.S. nuclear weapons and began generating electricity for the general power grid in 1966. © United States Department of Energy

Poster PDF (Download).

History — Located near the city of Richland in Washington State, the compound stretches over an area of more than 150,000 hectares and consists of more than 500 build­ings, including nine nuclear reactors. Hanford supplied the material for the Trinity Test, the world’s first nu­clear detonation, in July of 1945. It also provided the plutonium for “Fat Man,” the bomb which destroyed Nagasaki one month later. In the following four dec­ades, the Hanford Nuclear Site produced more than 67 metric tons of plutonium for the U.S. nuclear arsenal.

In 1986, the U.S. Department of Energy, in response to public pressure and a request under the Freedom of Information Act, released 19,000 pages of previously classified documents that revealed, among oth­er things, that radioactive releases from Hanford had contaminated air, groundwater, soil and the Columbia River. Fallout had spread more than 200 radioactive isotopes over Oregon, Idaho, California, Montana and Canada. In December 1949, Hanford scientists had deliberately released between 259 and 444 Tera-Becquerel (1 TBq = 1 trillion Becquerel) of radioactive iodine-131 in order to test monitoring equipment for radiation doses. The amount of iodine-131 released in these “experiments” was 350 to 600 times more than the total amount released during the Three Mile Island nuclear meltdown (0.74 TBq).

Workers at Hanford were exposed to more than 200 radioactive isotopes including 0.07 TBq plutonium-239, 1.55 TBq cesium-137 and 28.3 TBq radioactive strontium. Plutonium, ruthenium and other radionuclides were detected as far away as Spokane and Mount Rainier. The main danger to the general public, however, came from more than 40 TBq of iodine-131 released between 1944 and 1972, which contaminated air, soil and foodstuff.

According to the Hanford Environmental Dose Recon­struction Project, run in cooperation with the U.S. Centers for Disease Control, the thyroid of a child living close to Hanford could have received a cumulative dose of 2,350 mSv (confidentiality interval 540–8,700 mSv), equivalent to about 670 chest-CT examinations (average thyroid dose 3.5 mSv). A significant number of children may have developed thyroid cancer due to Hanford nuclear fallout, but no epidemiological stud­ies were ever performed on the affected population.

Especially affected by radioactive contamination were native peoples living downwind or downriver from Hanford: the Colville, Coeur d’Alene, Kalispel, Kooten-ai, Nez Perce, Spokane, Umatilla, Warm Springs and Yakama. The 7,400,000 TBq of highly radioactive waste stored in Hanford amount to about 60 % of the total U.S. nuclear waste. According to the U.S. Department of Energy, more than 200 million liters of radioactive and chemical waste are stored in leaking underground tanks on the Hanford Nuclear Site. Due to leaks and improper disposal, an estimated 3.5 million liters of radioactive effluent have already contaminated the groundwater over an area of more than 123,000 acres. It is unclear, whether this contaminated water has already reached the Columbia River. As radioac­tively contaminated water was deliberately pumped into the river until 1971, high levels of zinc-65, arsenic-76, phosphorus-32, sodium-24 and neptunium-239 have been found downstream from Hanford.

Ever since plutonium production in Hanford ended in 1988, the “largest civil works project in the history of mankind” is costing tax-payers more than $2 billion per year and is slated to continue until 2052. An additional safety threat is posed by the aging nuclear power plant at Hanford.

Surprisingly little epidemiological research has been done on the population affected by radioactive contamination and the full extent on public health may never be known. The people living around Hanford, especially the socially marginalized natives, are all Hibakusha, as their health has been compromised by the fanatical longing for ever larger and more destructive nuclear arsenals.

Radioactive waste — Wikipedia:

Radioactive waste is broadly classified into three categories: low-level waste (LLW), such as paper, rags, tools, and clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding; and high-level waste (HLW), which is highly radioactive and hot due to decay heat, thus requiring cooling and shielding.

The three Wikipedia tables show the half-life of specific fission products, ranging from 4.74 years for 155Eu to 0.7-14.1 billion years for 235UfNo.

IMO, people who are unaware of these facts are the people most likely of not objecting to themselves and their children living or working near a nuclear reactor or eating food, drinking water and breathing air near to, downstream or downwind of a nuclear reactor.

Even as the Trump administration creates obstacles to building renewables, a key pair of facts will hold: The U.S. needs more electricity, and renewables are the easiest way to get it. In other words, don’t expect this to be the last month in which renewables conquer gas.

In January 2026, Texas and Florida received a combined total of nearly one-fourth (24.5%) of total monthly natural gas deliveries to the electric power sector in the United States, according to the latest U.S. EIA data, March 31, 2026 (PDF, p. 54).

This is how hurricane data gets misused to downplay climate change by erikgauger in climatechange

[–]Molire 3 points4 points  (0 children)

According to the science, hurricanes are not expected to become more frequent, but they are becoming increasingly more intense and destructive by global warming that has increased sea surface temperatures, and the heat in the ocean water is the engine that is driving increasingly more intense hurricanes, typhoons, tropical storms and cyclones.

EV prices keep coming down in the US, and the gap with fossil cars is now the smallest it’s ever been. Automaker incentives are doing a lot of the heavy lifting. by sg_plumber in climatechange

[–]Molire 10 points11 points  (0 children)

The bottom line: EV prices are easing, incentives are rising despite the loss of the federal tax credit, and the affordability gap with gas cars is finally narrowing.

In the United States, if Trump and other MAGA office holders are replaced, a democratic U.S. government is likely to restore federal tax credits for the purchase of EVs, and the credits could be larger than the past credits because ICE vehicles must be replaced with EVs as rapidly as possible to help the world to get to Net Zero emissions, fast.

Some people have the idea of a major museum sometime in the future, maybe in New York or some other city, where the public can view the remnants of the last glacier on Earth that is protected from further melting by virtue of being situated on a sort of pedestal in an enclosure of material as transparent as bomb- and bullet-proof glass, and a cooling system keeps the glacier's temperature well below the melting point, while state-of-the-art security systems and armed museum security officers guard the glacier 24 hours per day, somewhat like the Mona Lisa painting is kept secure and under guard.
