Our pathetically slow shift to clean energy, in five charts

January 10th, 2020 at 12:11 pm » Comments Off

We’d better pick up the pace in the 2020s. By most measures that matter, clean energy had a stellar decade. The cost of large wind and solar farms dropped by 70% and nearly 90%, respectively. Meanwhile, renewable-power plants around the world are producing four times more electricity than they did 10 years ago. Similarly, electric […]



Impossible Foods’ faux pork is just as convincing as its fake beef

January 10th, 2020 at 12:03 pm » Comments Off

It can be used in dumplings, baos and more. Last year, Impossible Foods made headlines at CES when it introduced a new formulation of its Impossible Burger. It tasted so close to the real deal that we even gave it a Best of CES award. Now, Impossible Foods is back again at the annual tech […]



This leaf-shaped bottle cap condenses and collects atmospheric moisture, turning it into drinking water

January 7th, 2020 at 10:01 pm » Comments Off

Designed to magically ‘turn air into water’, the Limbe is a new sort of dehumidifier that works without electricity, giving its user access to drinking water throughout the day. Its unique leaf-inspired design harks back to how water droplets condense on the surface of leaves, while its 3D printed intricate PET structure helps guide those […]



Heavy-duty trucks and buses must go electric, says new report

December 20th, 2019 at 2:44 am » Comments Off

The electrification of trucks and buses needs to be accelerated, says a new report released yesterday by the Union of Concerned Scientists (UCS).  The UCS report, titled “Ready for Work: Now Is the Time for Heavy-Duty Electric Vehicles,” states that there are currently about 28 million trucks and buses in the US, or 10% of […]



5 emerging energy technologies to watch out for in 2020

December 12th, 2019 at 12:22 pm » Comments Off

2019 was a year of consolidation rather than breakthroughs for clean energy technologies. Will 2020 be different? This year will likely be remembered as a period of technology consolidation rather than breakthrough innovation in the energy industry. Emerging industries such as offshore wind and lithium-ion battery storage have gone from strength to strength. Meanwhile, more […]



New, slippery toilet coating provides cleaner flushing, saves water

Penn State researchers have developed a method that dramatically reduces the amount of water needed to flush a conventional toilet, which usually requires 6 liters. Credit: Wong Laboratory for Nature Inspired Engineering, Penn State Every day, more than 141 billion liters of water are used solely to flush toilets. With millions of global citizens experiencing […]



Large ‘Tesla ships’ all-electric container barges are launching this autumn

The Dutch company Port-Liner is building two giant all-electric barges dubbed the ‘Tesla ships‘. The company announced that the vessels will be ready by this autumn and will be inaugurated by sailing the Wilhelmina canal in the Netherlands. The 100 million-euro project supported by a €7m subsidy from the European Union is expected to have […]



A new floating solar farm shows that renewables can be easy

November 15th, 2019 at 12:19 pm » Comments Off

The Sekdoorn floating solar farm in the Netherlands is completed after a record six weeks of work. This is the fastest construction speed ever for the German company specialized in the renewables sector BayWa r.e., who worked together with its Dutch partner GroenLeven to build the power plant. The construction was done in only six […]



Porous polymer coatings dynamically control light and heat

November 10th, 2019 at 5:12 pm » Comments Off

The porous polymer coatings, which switch from white to transparent when wetted, can be put into plastic enclosures to make panels that control light and temperatures of buildings. Credit: Jyotirmoy Mandal/Columbia Engineering Buildings devote more than 30% of their energy use to heating, cooling, and lighting systems. Passive designs such as cool roof paints have […]



How cheap must batteries get for renewables to compete with fossil fuels?

November 4th, 2019 at 1:47 pm » Comments Off

Production of lithium batteries for environmentally friendly electric cars future of energy  While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can’t provide the 24/7 power we’ve become used to. At present, that’s not big a problem because the grid still features […]



In this “biorecycling” factory, enzymes perfectly break down plastic so it can be used again

October 27th, 2019 at 12:53 pm » Comments Off

In this “biorecycling” factory, enzymes perfectly break down plastic so it can be used again  The process lets any plastic—say a polyester shirt—be recycled into any other plastic (like a clear water bottle). It could fundamentally change the market for recycling. Inside a bioreactor in the laboratory of the France-based startup Carbios, pulverized PET plastic […]



Watch the world’s largest 3D-printer spit out a 25 foot boat

October 25th, 2019 at 11:33 am » Comments Off

…and how this is really about using wood to replace metal If you’re shopping for a 3D printer, a key consideration is bed size; what’s the largest object you’d realistically need to print? For the University of Maine’s Advanced Structures and Composites Center, size limitations aren’t so much of an issue. That’s because they’ve got […]
