World’s largest air-to-water heat pump to warm 30,000 homes in Finland

Finland’s capital city, Helsinki, is building the world’s largest heat pump to keep as many as 30,000 homes warm in the winter while reducing carbon emissions. The pump can operate at temperatures as low as -4 Fahrenheit (-20 degrees Celsius) while being powered by only renewable energy sources.

District heating is a commonly deployed mechanism to maximize energy efficiency. It centralizes heat production and distributes it to homes and businesses using a network of underground pipes. The approach is used in many cities worldwide but has conventionally relied on fossil fuels to generate heat.

According to the International Energy Agency report, half of Finland’s energy for heating and cooling comes from biomass. As Helsinki aims to become a carbon-neutral city by the end of the decade, the city administration is leveraging its centralized heating system to switch a large chunk of its energy consumption to a greener, renewable source.

“Helsinki has set the ambitious goal to become carbon neutral by 2030, and transitioning our heating system is crucial to achieving this,” said Juhani Aaltonen, VP of Green Investments at Helen Oy, the Finnish energy company that operates the heating unit.

Letters from an American: September 14, 2024

Five years ago, on September 15, 2019, after about a six-week hiatus during the summer, I wrote a Facebook post that started:

“Many thanks to all of you who have reached out to see if I'm okay. I am, indeed (aside from having been on the losing end of an encounter with a yellow jacket this afternoon!). I've been moving, setting up house, and finishing the new book. Am back and ready to write, but now everything seems like such a dumpster fire it's very hard to know where to start. So how about a general overview of how things at the White House look to me, today....”

I wrote a review of Trump’s apparent mental decline amidst his faltering presidency, stonewalling of investigations of potential criminal activity by him or his associates, stacking of the courts, and attempting to use the power of the government to help his 2020 reelection.

Then I noted that the chair of the House Intelligence Committee, Representative Adam Schiff (D-CA), had written a letter to the acting director of national intelligence, Joseph Maguire, on Friday, September 13, telling Maguire he knew that a whistleblower had filed a complaint with the inspector general of the intelligence community, who had deemed the complaint “credible” and "urgent.” This meant that the complaint was supposed to be sent on to the House Intelligence Committee. But, rather than sending it to the House as the law required, Maguire had withheld it. Schiff’s letter told Maguire that he’d better hand it over. Schiff speculated that Maguire was covering up evidence of crimes by the president or his closest advisors.

And I added: “None of this would fly in America if the Senate, controlled by Majority Leader Mitch McConnell of Kentucky, were not aiding and abetting him.”

“This is the story of a dictator on the rise,” I wrote, “taking control of formerly independent branches of government, and using the power of his office to amass power.”

Readers swamped me with questions. So I wrote another post answering them and trying to explain the news, which began breaking at a breathtaking pace.

And so these Letters from an American were born.
