Iceland: Powered by the Earth’s Fire – A Geothermal Wonderland
Iceland, a land of glaciers and volcanoes, straddling the Mid-Atlantic Ridge, harnesses the earth’s inner heat like no other.
Geothermal energy, the gift of a fiery core and colliding tectonic plates, has become the lifeblood of this Nordic island nation. Let’s delve into the world of Iceland’s geothermal energy marvel and explore its impact on the country’s landscape, people, and future.
From Humble Beginnings to a National Treasure:
Iceland’s geothermal journey began long ago, with early settlers bathing in natural hot springs. Today, the utilization has reached astonishing heights. Over 25% of the country’s electricity comes from geothermal power plants, with giants like Hellisheidi and Nesjavellir feeding the grid. But the magic goes beyond electricity. A staggering 90% of Icelandic homes are heated by geothermal water, a testament to its efficiency and abundance.
Beyond Electricity: A Web of Geothermal Uses:
The benefits of Iceland’s geothermal bounty extend far beyond powering homes and lights. Greenhouses flourish under the warmth of this renewable resource, allowing Iceland to cultivate fresh produce year-round and reduce dependence on imports. The iconic Blue Lagoon, a milky blue geothermal spa, attracts tourists from around the world, showcasing the beauty and tranquility of this natural wonder. Streets even benefit, with geothermal water keeping sidewalks ice-free during harsh winters.
Sustainability and the Future:
Iceland’s reliance on geothermal energy positions it as a global leader in renewable energy. It’s a beacon of hope in the fight against climate change, demonstrating the feasibility and benefits of harnessing the earth’s natural heat. Research and development continue, pushing the boundaries of geothermal technology and exploring its potential for even wider applications.
Challenges and Considerations:
Despite its success, Iceland’s geothermal journey isn’t without challenges. Environmental concerns around drilling and potential disruptions to delicate ecosystems require careful monitoring and responsible management. Balancing energy needs with the protection of the natural world is a constant balancing act.
A Geothermal Legacy:
Iceland’s story with geothermal energy is one of ingenuity, adaptation, and a deep respect for the power of nature.

North Sea Summit Commits to 100 GW Offshore Wind

North Sea Summit Commits to 100 GW Offshore Wind
Allen covers Equinor’s Hywind Tampen floating wind farm achieving an impressive 51.6% capacity factor in 2025. Plus nine nations commit to 100 GW of offshore wind at the North Sea Summit, Dominion Energy installs its first turbine tower off Virginia, Hawaii renews the Kaheawa Wind Farm lease for 25 years, and India improves its repowering policies.

There’s a remarkable sight in the North Sea right now. Eleven wind turbines, each one floating on water like enormous ships, generating electricity in some of the roughest seas on Earth.
Norwegian oil giant Equinor operates the Hywind Tampen floating wind farm, and the results from twenty twenty-five are nothing short of extraordinary. These floating giants achieved a capacity factor of fifty-one point six percent throughout the entire year. That means they produced power more than half the time, every single day, despite ocean storms and harsh conditions.
The numbers tell the story. Four hundred twelve gigawatt hours of electricity, enough to power seventeen thousand homes. And perhaps most importantly, the wind farm reduced carbon emissions by more than two hundred thousand tons from nearby oil and gas fields.
Production manager Arild Lithun said he was especially pleased that they achieved these results without any damage or incidents. Not a single one.
But Norway’s success is just one chapter in a much larger story unfolding across the North Sea.
Last week, nine countries gathered in Hamburg, Germany for the North Sea Summit. Belgium, Denmark, France, Britain, Ireland, Luxembourg, the Netherlands, Norway, and their host Germany came together with a shared purpose. They committed to building one hundred gigawatts of collaborative offshore wind projects and pledged to protect their energy infrastructure from sabotage by sharing security data and conducting stress tests on wind turbine components.
Andrew Mitchell, Britain’s ambassador to Germany, explained why this matters now more than ever. Recent geopolitical events, particularly Russia’s weaponization of energy supplies during the Ukraine invasion, have sharpened rather than weakened the case for offshore wind. He said expanding offshore wind enhances long-term security while reducing exposure to volatile global fossil fuel markets.
Mitchell added something that resonates across the entire industry. The more offshore wind capacity these countries build, the more often clean power sets wholesale electricity prices instead of natural gas. The result is lower bills, greater security, and long-term economic stability.
Now let’s cross the Atlantic to Virginia Beach, where Dominion Energy reached a major milestone last week. They installed the first turbine tower at their massive offshore wind farm. It’s the first of one hundred seventy-six turbines that will stand twenty-seven miles off the Virginia coast.
The eleven point two billion dollar project is already seventy percent complete and will generate two hundred ten million dollars in annual economic output.
Meanwhile, halfway across the Pacific Ocean, Hawaii is doubling down on wind energy. The state just renewed the lease for the Kaheawa Wind Farm on Maui for another twenty-five years. Those twenty turbines have been generating electricity for two decades, powering seventeen thousand island homes each year. The new lease requires the operator to pay three hundred thousand dollars annually or three point five percent of gross revenue, whichever is higher. And here’s something smart: the state is requiring a thirty-three million dollar bond to ensure taxpayers never get stuck with the bill for removing those turbines when they’re finally decommissioned.
Even India is accelerating its wind energy development. The Indian Wind Power Association welcomed major amendments to Tamil Nadu’s Repowering Policy last week. The Indian Wind Power Association thanked the government for addressing critical industry concerns. The changes make it significantly easier and cheaper to replace aging turbines with modern, more efficient ones.
So from floating turbines in the North Sea to coastal giants off Virginia, from island power in Hawaii to policy improvements in India, the wind energy revolution is gaining momentum around the world.
And that’s the state of the wind industry for the 26th of January 2026.
Join us tomorrow for the Uptime Wind Industry Podcast.

God’s Proud of Trump?
Based on the polls, we can see that most of the American people have a seething hatred of Trump, but at least God thinks he’s done a good job.
