The amount of energy required by direct air carbon capture proves it is an exercise in futility
Removing CO2 directly from the air requires almost as many joules as those produced by burning the fossil fuel in the first place, writes Leigh Collins

Consumers, not corporations, saved the power grid. What else can we do?
World leaders are once again preparing to meet next month to discuss how they’ll address climate change. Known as COP27, the two-week conference in Egypt will gather governments, large corporations, and nonprofit groups, representing billions of people and billions of dollars, all aiming to hash out how best to keep the planet from warming up too much.

The Middle East is going green — while supplying oil to others
The world’s green spotlight is tilting towards the Middle East as Egypt and the United Arab Emirates (UAE) prepare to host the next two major world summits on climate change. Egypt’s Sharm El-Sheikh resort will be the site of the next United Nations Climate Change Conference of the Parties (COP27), which begins on 6 November, and the UAE’s oil giant Abu Dhabi will host COP28 in 2023.

Schools are harnessing solar power in record numbers
In 2014, two solar energy groups published a report finding that only about 3,750 U.S. schools — out of a total of roughly 130,000 — were generating electricity from solar panels. But that number is on the rise. According to the fourth edition of the “Brighter Future” report, released last week by the clean energy nonprofit Generation180, the number of U.S. schools using solar power has more than doubled in the last seven years, reaching roughly 8,400 by the end of 2021.

Out of this world: Floating solar farm could power a million homes
It sounds like the stuff of science fiction - but Europe might one day be powered by giant floating solar panels orbiting the planet. The European Space Agency (ESA) has unveiled a plan to harvest the sun’s energy in space and beam it back down to Earth.

The first 'utility scale' renewable energy plant combining solar and wind generation with battery storage opens in the US
A utility-scale renewable energy plant using wind and solar combined with battery storage opened last week, a US first, with the potential of powering 100,000 homes with clean, reliable energy. The project gives us a glimpse into the future as the US shifts from fossil fuels to clean energy sources.

Geospatial Data: Its Value and Types
Geospatial data is one of the fundamentals of digital transformation, linking unconnected data sets. Such data is used in a variety of applications, including digital land registry development, advanced infrastructure planning, public data collection and sharing, or digitization of cadastral records. Geospatial data providers put a huge amount of time, effort, and finances into the transformation of their services so that they benefit people, businesses, and authorities.

Floating Artificial Leaf Turns CO2 Into Fuel
A new artificial leaf is light enough to float on water, where it can soak up sunlight and carbon dioxide from air, and use the water below to produce fuels. Researchers at Cambridge University tested their 100-square-centimeter artificial-leaf device outdoors on a river. Depending on the catalyst used, the device either splits water to produce hydrogen fuel, or converts carbon dioxide into syngas, a mix of carbon monoxide and hydrogen that is used to make other fuels like methanol. Fleets of such devices could be deployed on brackish water ponds, canals, and on seas, so as not to compete with land use, they say.

Lithium-ion batteries: One size does not fit all in application or in assessment
Seeing is believing—or, rather, seeing can aid in understanding, especially when it comes to the mechanisms underpinning lithium-ion batteries. Despite near-ubiquitous use in cell phones, computers and more, the complex electrochemical environments of lithium-ion batteries remain murky.
