Google and Microsoft consume more power than some countries

Posted by in categories: energy, sustainability

In 2023, Google and Microsoft each consumed 24 TWh of electricity, surpassing the consumption of over 100 nations, including places like Iceland, Ghana, and Tunisia, according to an analysis by Michael Thomas. While massive energy usage means a substantial environmental impact for these tech giants, it should be noted that Google and Microsoft also generate more money than many countries. Furthermore, companies like Intel, Google, and Microsoft lead renewable energy adoption within the industry.

Detailed analysis reveals that Google’s and Microsoft’s electricity consumption — 24 TWh in 2023 — equals the power consumption of Azerbaijan (a nation of 10.14 million) and is higher than that of several other countries. For instance, Iceland, Ghana, the Dominican Republic, and Tunisia each consumed 19 TWh, while Jordan consumed 20 TWh. Of course, some countries consume more power than Google and Microsoft. For example, Slovakia, a country with 5.4 million inhabitants, consumes 26 TWh.

Highly efficient and stable solar cells can now be mass produced like printing newspapers

Posted by in categories: solar power, sustainability

Scientists at the City University of Hong Kong (CityUHK) have developed highly efficient, printable and stable perovskite solar cells to achieve carbon neutrality and promote sustainable development.

The new type of solar cells can be mass-produced at a speed comparable to newspaper printing, with a daily output of up to 1,000 . Owing to their flexible, semi-transparent characteristics, they can also be made into light-absorbing glass windows, realizing the concept of “urban solar farms” in cities with many high-rise buildings.

The research is led by the Lee Shau Kee Chair Professor of Materials Science at CityUHK, Professor Alex Jen Kwan-yue, and the results were published in Nature Energy.

Space Exploration: A Thriving Industry With Tangible Earthly Rewards

Posted by in categories: economics, education, health, law, space travel

Furthermore, the synergy between educational programs, cultural influences and the tangible benefits derived from space exploration not only enriches our present-day society but also ensures a legacy of continuous innovation and exploration. This ongoing engagement with space inspires future generations to look beyond our planetary boundaries and consider what might be possible in the broader cosmos.

Space exploration presents significant challenges, including costs, astronaut health risks and technological hurdles for interstellar travel. Ethical and legal considerations regarding space colonization, resource utilization and celestial environmental impact require careful consideration and international cooperation.

While Silicon Valley visionaries envision a future among the stars, other voices remind us of our responsibilities to Earth. These are not mutually exclusive goals. By leveraging advancements and opportunities from space exploration, we can better protect and enhance life on Earth. Through economic benefits, scientific advancement and social inspiration, space exploration remains a crucial endeavor for humanity, not as an escape from our problems, but as a way to expand our horizons and solve them on our home planet.

Investigating the Origins of the Crab Nebula

Posted by in categories: cosmology, sustainability

A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that is helping to clarify the Crab Nebula’s history.

The Crab Nebula is the result of a core-collapse supernova from the death of a massive star. The supernova explosion itself was seen on Earth in 1,054 CE and was bright enough to view during the daytime. The much fainter remnant observed today is an expanding shell of gas and dust, and outflowing wind powered by a pulsar, a rapidly spinning and highly magnetized neutron star.

The Crab Nebula is also highly unusual. Its atypical composition and very low explosion energy previously have been explained by an electron-capture supernova — a rare type of explosion that arises from a star with a less-evolved core made of oxygen, neon, and magnesium, rather than a more typical iron core.
