What’s the weather like on Titan?
Most of the planets in our solar system have some sort of atmosphere and many have dynamic weather systems. But only one moon in the solar system, Saturn’s large moon Titan, can say the same. Source: https://earthsky.org/space/titan-saturns-moon-weather-seasons-methane-rain-storms…
Our world is losing ice at a record rate
The rate at which ice is disappearing across the planet has been speeding up, with 65% since the 1990s, a survey of global ice loss using European Space Agency satellite data reveals. Source: https://earthsky.org/earth/esa-satellites-show-record-rate-ice-loss…
Are We Slowing Global Warming?
This week New York Magazine featured a new article by journalist David Wallace-Wells about the state of the fight against global warming. He warns that “Already, the planet is warmer, at just 1.2 degrees, than it has ever been…” But there’s also some good news:
Just a half-decade ago, it was widely believed that a “business as usual” emissions path would bring…

World’s First Ocean Hybrid Platform Converts Tidal Waves Into Energy
Qusi Alqarqaz writes via IEEE Spectrum: In August I spoke with Philipp Sinn, founder of Sinn Power, a German green-energy startup founded in 2014. This year he and his colleagues began building and testing the world’s first ocean hybrid platform. The floating platform uses a combination of wave, wind, and solar energy to harness renewable energy on the open seas, Sinn…
In World First, 100% of South Australia’s Power Supplied By Solar Panels
1.76 million people live in the 983,482 square kilometer (379,725 square mile) state of South Australia. This weekend Australia’s national broadcaster made a big announcement: South Australia’s renewable energy boom has achieved a global milestone. The state once known for not having enough power has become the first major jurisdiction in the world to be powered entirely by solar energy. For…
One Solar/Wind Energy Company Is Now More Valuable Than Exxon Mobil
The world’s biggest provider of wind and solar energy is now more valuable than the giant oil company Exxon Mobil, “once the largest public company on Earth,” reports Bloomberg: NextEra ended Wednesday with market value of $145 billion, topping Exxon’s $142 billion… NextEra has emerged as the world’s most valuable utility, largely by betting big on renewables, especially wind. Exxon has…
Researchers Use Supercomputer to Design New Molecule That Captures Solar Energy
Iwastheone shares some news from Sweden’s Linköping University:
The Earth receives many times more energy from the sun than we humans can use. This energy is absorbed by solar energy facilities, but one of the challenges of solar energy is to store it efficiently, such that the energy is available when the sun is not shining. This led scientists at Linköping University…
