The surge in online shopping, accelerated by COVID-19, has driven up the demand for package deliveries, and that demand continues to rise.

As traditional delivery methods contribute to urban traffic congestion and pollution, cargo bikes - a staple of bike-friendly countries like Denmark and the Netherlands - are becoming a common sight in cities across Europe as a sustainable and efficient alternative to vans.

These larger, typically electric bikes with separate carriers can transport a wide range of loads, from small parcels to larger items, making them ideal for urban deliveries.

In Europe, it is estimated that up to 50 per cent of motorised trips involving the transport of goods in cities could be made by cargo bikes and bicycles, according to a recent study.

On Tuesday, service workers rallied at major airports in Charlotte, North Carolina, and Phoenix. They called for immediate action from employers to ensure their safety in the workplace, including adequate breaks and access to drinking water during periods of extreme heat.

In Phoenix, where earlier this year local officials enacted a heat ordinance mandating many of these protections, workers and legislators sounded the alarm that the ordinance has led to inadequate improvements, and questioned how the protections are being enforced. “Why is it after passing an ordinance we’re still asking for the basics? Water. Breaks. These are humans rights,” said City of Phoenix Councilwoman Betty Guardado at the rally. Later this week, laborers across the country will be taking a coordinated water break to signify the need for access to drinking water at work.

As human-caused climate change continues to make the planet hotter, extreme heat in the workplace is increasingly becoming a lethal threat. Organizers say “Heat Week” is also spurred by the recent sudden deaths of Wednesday “Wendy” Johnson, a postal worker in North Carolina, and Ronald Silver II, a sanitation worker in Maryland. Both Johnson and Silver are believed to have died, in part, because of on-the-job heat exposure, which kills dozens of workers every year.

From January through July of this year, wind and solar in the U.S. generated more net electricity than power from coal, according to recent data from the U.S. Energy Information Administration (EIA).

According to the EIA’s Monthly Energy Review for July 2024, electricity net generation from renewable energy outpaced coal for the first seven months of the year so far, a first for the U.S.

Further, wind energy generation alone beat coal energy generation in two consecutive months: March and April. As CleanTechnica reported, wind energy installations produced 45.9 gigawatt-hours (GWh) in March and a record high 47.7 GWh in April, compared to the 38.4 GWh in March and 37.2 GWh in April generated by coal-fired power plants.

Researchers at Martin Luther University Halle-Wittenberg (MLU) have discovered a new method to increase the efficiency of solar cells by a factor of 1,000. The team of scientists achieved this breakthrough by creating crystalline layers of barium titanate, strontium titanate, and calcium titanate, which were alternately placed on top of one another in a lattice structure.

Their findings, which could revolutionize the solar energy industry, were recently published in the journal Science Advances.

Companies whose futures depend on plastic production, including oil and gas giant ExxonMobil, are trying to persuade the federal government to allow them to put the label “recyclable” on bags and other plastic items virtually guaranteed to end up in landfills and incinerators.

They argue that “recyclable” should apply to anything that’s capable of being recycled. And they point to newer technologies that have been able to remake plastic bags into new products.

I spent months investigating one of those technologies, a form of chemical recycling called pyrolysis, only to find that it is largely a mirage. It’s inefficient, dirty and so limited in capacity that no one expects it to process meaningful amounts of plastic waste any time soon.

Clayton Page Aldern is a former neuroscientist turned environmental journalist. He is currently a senior data reporter at the climate magazine Grist. His work focuses on the intersection of climate change and human health, particularly the neurological impacts of environmental factors.

Below, Clayton shares five key insights from his new book, The Weight of Nature: How a Changing Climate Changes Our Brains.

There are a handful of states that are doing a great job crafting solar policy that makes it affordable and accessible for homeowners and renters alike to go solar. No state has created the perfect set of legislative conditions that make it easier or cheaper for residents to install solar panels, but these are the states that have the best solar incentives right now.

When looking at the majority of comments going on certain online forums you can end up thinking that the vast majority of solarpunks all think the same way on certain issues.

Whether it’s plant-based diets, or the role of traditional media it can seem like 80%+ of the people are in agreement, sometimes very strong agreement and denounce alternative interpretations as not solarpunk at all.

This is why the pioneering research by Benjamin Maldonado Fernandez is so interesting. As part of his studies at the university of Leiden he conducted a survey of people in the solarpunk scene which gained 571 respondents, making it one of the largest, if not the largest so far. It had a wide range of questions which you can see all of in the published results here.

We interviewed Benjamin to unpack some of the findings of the survey.

Peru's reclusive Mashco Piro ethnic group recently used bows and arrows to attack loggers suspected of encroaching on their territory in the Amazon, according to a regional Indigenous organization.

FENAMAD, representing 39 Indigenous communities in the Cusco and Madre de Dios regions, said Monday that it believes illegal logging was taking place on Mashco Piro territory and that one logger was injured in the July 27 attack.

Cooling represents 20% of global electricity demand in buildings, a share that’s expected to rise as the planet warms and more of the world turns to cooling technology. During peak demand hours, air conditioners can account for over half the total demand on the grid in some parts of the world today.

New cooling technologies that incorporate energy storage could help by charging themselves when renewable electricity is available and demand is low, and still providing cooling services when the grid is stressed.

Scientists from across academic disciplines are extremely concerned about climate change. Many of them have already changed their own lifestyles or engaged in advocacy and protest, with even more being willing to do so in future.

This is evident from a large-scale survey of scientists from all over the world, conducted by an international research team led by the University of Amsterdam. The researchers not only looked at the views of scientists and the extent to which they are engaged in climate action, but also at how the involvement of scientists with climate change can be increased.

For the first time ever, California's batteries took over gas as the primary source for supplying evening power demand in April, providing "akin to the output from seven large nuclear reactors" one evening, according to the New York Times.

These records were broken in the Californian spring, when there was plenty of sunshine without the summer heat that causes people to turn on the air-conditioning and consume more power, but it's a sign of the shift underway.
