Why we think Theia existed

by Paul M. Sutter
February 18, 2025

The giant-impact hypothesis posits that billions of years ago a
Mars-sized body named Theia collided with the early Earth.

The immense energy from this impact not only significantly
altered Earth's rotational dynamics but also resulted in debris
being ejected into space. Over time, this debris coalesced to
form the Moon.

We do not know for sure if Theia existed and if it collided with
the young proto-Earth, but the evidence is compelling.

For one, we are the only rocky planet with a substantial moon.
Mercury and Venus have none, while Mars lays claim to only two
small, captured asteroids. The very existence of our large moon
demands explanation.

Second, there's spin. The Earth spins much faster than the other
rocky planets, and the Moon orbits around us at a surprisingly
swift pace. Something deep in our past must have provided all
that energy, and a collision with another protoplanet explains it
with ease.

Lastly, we have an unexpected piece of evidence from our human
adventures to the Moon. The Apollo missions were more than
pursuits of glory; they were scientific enterprises. Trained by
expert geologists, the Apollo astronauts, beginning with
Armstrong and Aldrin, where taught to search for and extract
interesting findings.

What they returned to Earth revealed an enormous wealth of
scientific knowledge of the Moon's composition, because for the
first time we were able to acquire large amounts of regolith—the
generic term for the loose material that makes up the lunar
surface—and return it to Earth for further study. All told, the
six successful Apollo missions brought back 2,200 samples
totaling almost 400 kilograms of material.

The regolith returned by the Apollo missions displayed a
remarkable property: the lunar surface is oddly similar in
constitution to the Earth's crust, with similar ratios of
elements. The only conclusion is that we must have a common
origin.

So while we are never able to turn the clock back and witness the
formation of the Earth and Moon, we can use the clues scattered
around us to help us understand this cataclysmic event that took
place over four billion years ago.

Major test case for new geothermal technology launches in small
German town

by Jennifer McDermott
February 17, 2025

Residents in the German town of Geretsried have long wanted to
run their buildings with clean heat and electricity from
geothermal energy instead of fossil fuels.

Their hopes were dashed about 15 years ago when a drilling
company couldn't find enough hot water close to the surface to be
profitable using traditional geothermal technology. That
basically left them with natural gas.

"We gave up. We had big hopes," recalled First Mayor of
Geretsried Michael Müller, who was raised in the town.

Today the next generation of geothermal companies is trying to
succeed where previous efforts failed. They don't rely on hot
water close to the surface, but instead use techniques developed
in the oil and gas industry to drill deep and extract heat from
dry, hot rock. One of them, Eavor, is starting up its first
commercial power plant in Geretsried—turning the tiny town of
about 26,000 people, south of Munich, into a proving ground for
the future of geothermal energy.

Can technology like this be scaled and really make a difference
for the future of the planet? The International Energy Agency
thinks so. In a recent report, it said technology breakthroughs
are unlocking huge potential for geothermal energy. Now that
companies are drilling deeper than 3 kilometers (close to 2
miles), nearly every country has the potential to make heat and
electricity this way, the IEA said.

"It has been a niche energy and concentrated in a few countries,"
IEA Executive Director Fatih Birol said in an interview. But
soon, Birol said, "geothermal can contribute to the global energy
picture in an accelerated manner."

Eavor was drawn to Geretsried because the traditional
technique failed there

Eavor CEO John Redfern said the earlier failure in Gerestried
opened up the possibility for a high-profile success—Geretsried's
ordinary geology was appealing. No one would've been impressed if
the Canadian company demonstrated its technology in Iceland, a
place with abundant, easily accessible hot water, he added.

It helped that the town was excited for geothermal and open to
new ideas, he added.

"Our whole point is that we want to have geothermal anywhere,
everywhere," Redfern said. "What better way to prove that than to
put our first well where they tried and failed with traditional
geothermal systems."

Germany is committed to transitioning away from fossil fuels. As
part of the commitment, heating systems must switch to renewable
sources because heating is one of the main sources of carbon
dioxide emissions in Germany. And Germany couldn't depend on
importing natural gas from Russia after Russia invaded Ukraine in
2022.

Eavor, named for the phrase "energy for ever," has a
demonstration facility in Alberta, Canada. Company executives
know Geretsried well. One of them managed operations for the
contractor that drilled there previously.

Eavor says Geretsried geothermal will power up this year.
That would be a milestone

This project will start by generating electricity in Geretsried,
then add heat as the town fully builds out a district heating
system.

With district heating, heat is generated in a central location
and distributed to homes and businesses. Most of these systems
make their heat from burning fossil fuels, especially in China
and Russia, which have the largest number of them, according to
the IEA. Europe has 17,000 district heating and cooling networks,
serving 67 million people, according to Euroheat & Power, the
international network for district energy.

In the United States, district energy systems are most often on
college campuses, at hospitals, on military bases and in some
downtown areas in larger cities. Some universities are switching
their district heating systems off gas or heating oil to
geothermal energy to address climate change. The Trump
administration, while pivoting back to pro-oil and gas policies,
does appear to also favor geothermal.

Eavor has a contract to provide heat in the northwestern German
city of Hanover, too. The city of more than 500,000 people is
phasing out coal.

Eavor is also licensing its technology to utilities and companies
that are trying to curb emissions and want secure energy, Redfern
said. A large Japanese power provider, Chubu Electric Power
Company, is a major investor in Eavor. Japan has many sites
suitable for geothermal but few geothermal power plants.

How does this geothermal method work?

The way it works is that Eavor drills two wells about 4
kilometers (2.5 miles) deep, then branches out and drills a dozen
lateral wells, to maximize contact with the hot rock. The wells
intersect to create a closed loop where water can flow, the
"Eavor loop." The Geretsried project will have four loops, each
with two vertical wells and about 12 lateral ones.

Eavor does not frack, or hydraulically fracture, to create cracks
and increase the permeability of rock.

Instead in Geretsried, it will pump water down to flow through
the hot rock, heating up on contact. It will rise naturally to
the surface through an outlet well.

That hot water can be used to heat the utility's water so it can
be sent through pipes to heat the equivalent of about 36,000
homes. The hot water also can be routed to a power plant to make
steam and then recirculated. When used to spin a turbine, that
steam can generate electricity without any planet-warming
greenhouse gas emissions.

Müller, the mayor, said it's better to start changing the
approach to energy today than push it off to tomorrow. He said
residents can't rely on fossil fuels long term, they have to
address climate change and they need secure energy.

"We want to remain future proof," he said. "So let's start the
future."
