Science: Galaxies Without Dark Matter, High Helium Levels, Solar Energy Jump

Dark matter makes up most of the matter in the Universe, and is thought to be needed for galaxies to form. But four years ago, astronomers made a perplexing, and controversial discovery: two galaxies seemingly devoid of dark matter. 

This week the team suggests that a cosmic collision may explain how these, and a string of other dark-matter-free galaxies, could have formed.

The World Economic Forum is the International Organization for Public-Private Cooperation. The Forum engages the foremost political, business, cultural and other leaders of society to shape global, regional and industry agendas. We believe that progress happens by bringing together people from all walks of life who have the drive and the influence to make positive change.

Renewable Energy: The Political Backlash (WSJ)

Political battles at the most local levels are slowing the pace of decarbonization Property owners in the windy and sunny parts of the U.S. are pushing back against large-scale renewable energy development, opposition that researchers say could slow the transition to a cleaner economy.

Views: Dominican Republic Shifts Into Green Energy

Small solar panels are to be installed on the roofs of houses in the village of Sabana Real, Dominican Republic. The local project is part of a major plan: By 2025, the country hopes to generate a quarter of its energy from renewable sources.

Analysis: How America Can Build & Run A 100% Clean Electric Grid (Video)

The U.S. electric grid is outdated. Designed for a world that runs on fossil fuels, our grid needs some major tech upgrades in order to transition to a more distributed, all-renewable system. That means smart, internet connected hardware working in tandem with advanced data analytics software to ensure that supply and demand are balanced, even when the sun isn’t shining or the wind isn’t blowing.

Investors have been pouring more money than ever into renewable energies such as solar and wind. WSJ looks at how the pandemic, lower energy costs and global politics have driven the rally–and whether it can last.

Net-Zero Tech: ‘Buildings Producing More Energy Than They Use’ (Video)

What if our buildings produced more energy than they used? From the United States to Hong Kong, these projects prove it can be done.

zero-energy building (ZE), also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), net zero building is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site,[1][2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels.

Mobile Living: Modern Shed – ‘The DW’ (Dwelling On Wheels) – “An Amazing Off-Grid Tiny Home”

Having provided customers with small backyard spaces for over two decades, Modern Shed has taken the next step in small space innovation. One that can be taken with you wherever you go. Introducing the DW (dwelling on wheels). This is more than a mobile shed on wheels.

Modern-Shed was born from builders and dreamers—idealists and pragmatic problem-solvers. The Modern Shed team was inspired to embark on a creative project in 2020–creating their first-ever portable dwelling. Drawing on their design/build expertise, the team created a beautiful, self-contained space big enough to call home, yet small enough to take anywhere: The Dwelling on Wheels –the DW– was born. A classic gable form creates a recognizable home, with wall-to-ceiling window placements maximizing landscape views and sunlight.

The Details

The resilient, low-maintenance envelope is contrasted by a bright and spacious wood interior and sustainable linoleum flooring. The DW offers room for three with a large bed–just a few inches short of a queen–tucked below a twin in the sleeping area. Thoughtfully designed, built-in storage accommodates small living while the glass wall orients the structure to capture the horizon in the living room.

With a solar array on the roof equipped with batteries, and a wood stove to provide warmth, the DW is equipped to be used off-grid. The dwelling comes with two electric wall heaters as a backup, and is ready to accommodate water tanks or a composting unit.

The DW exemplifies Modern-Shed’s values: creating beautiful dwellings efficiently, sustainably, and cleverly.
