Who is to blame for marine litter?

Members of the public are more likely to blame the global marine litter crisis on retailers, industry and government, according to new research led by the University of Plymouth. However, they have less faith in those agencies' motivation and competence to address the problem, placing greater trust in scientists and environmental groups to develop effective

Energy-Efficient Light Bulbs Harder to Find, More Expensive in High-Poverty Neighborhoods

One of the easiest ways for a household to save energy and money is to install energy-efficient light bulbs in as many sockets as possible. But, according to a new University of Michigan study, the low-income households that benefit most from these savings have a harder time finding CFL and LED bulbs than do households

Devon ‘log bank’ set up to help those struggling with fuel poverty

A band of volunteer foresters working from a base tucked away in a steep West Country valley is pioneering a “log bank” scheme designed to help struggling families and individuals out of fuel poverty. Inspired by the food bank system that has become a feature of austerity Britain, the idea is that people in Devon

How Solar Power Is Changing The Lives Of Some In The Philippines

In many parts of the developing world, tech entrepreneurs are trying to solve long-standing problems. We visit two of these places on this week's All Tech Considered. (SOUNDBITE OF ULRICH SCHNAUSS' "NOTHING HAPPENS IN JUNE") SHAPIRO: First to Occidental Mindoro, an island in the Philippines where power outages are a big problem. They're also an

Global warming can be limited to 1.5°C by changing how we travel, heat homes, use devices

A new study published in Nature Energy shows that dramatic transformations in the way we move around, heat and cool our homes, and buy and use devices and appliances in our cities can help raise living standards in the global South to meet UN Sustainable Development Goals while also remaining within the 1.5°C target set

In desert trials, next-generation water harvester delivers fresh water from air

Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight. The successful field test of their larger, next-generation harvester proved what the team had

Rural Georgians look to the sun to ease energy poverty

In the Georgian countryside, many are reliant on firewood for heating. Can local energy cooperatives help fight the resulting air pollution and deforestation, and help families save cash, with a solar-powered fix? Project aim: Replacing wood-burning stoves and other polluting heat sources with solar water heaters to improve air quality and prevent deforestation. Project partners:

Researchers shine a light on more accurate way to estimate climate change

DURHAM, N.H. – It doesn’t matter if it’s a forest, a soybean field, or a prairie, all plants take up carbon dioxide during photosynthesis – the process where they use sunlight to convert water and carbon dioxide into food. During this changeover, the plants emit an energy “glow” that is not visible to the human

Magic in metal could help put excess carbon dioxide to good use

The chunk of metal sitting on a table in Joel Rosenthal's office at the University of Delaware looks like it should belong in a wizard's pocket. Shiny silver with shocks of pink and splashes of gold, it's called bismuth, and it's currently used to make products ranging from shotgun pellets to cosmetics and antacids, including

Can off-grid renewables close the energy access gap?

BRATISLAVA, Slovakia — Solar lightbulbs, mini power grids, and batteries could soon supply energy to disadvantaged, rural regions that old-fashioned transmission lines and centralized coal-fired generators will never reach. But while prices of renewables have tumbled, and some say the technology offers lower-income countries the chance to leapfrog over more cumbersome ways of delivering energy, significant challenges

Atomically thin nanowires convert heat to electricity more efficiently

Waste heat can be converted to electricity more efficiently using one-dimensional nanoscale materials as thin as an atom -- ushering a new way of generating sustainable energy -- thanks to new research by the University of Warwick. Led by Drs Andrij Vasylenko, Samuel Marks, Jeremy Sloan and David Quigley from Warwick's Department of Physics, in

What does the future of energy look like?

Fossil fuels like coal, oil and natural gas supply 80 percent of the world’s energy to warm homes, charge devices and power transportation. They are also the primary human source of greenhouse gas emissions. Stanford scientists broadly agree that curtailing our use of fossil fuels would have significant benefits – like improving health and reducing

Dusty Rainfall Records Reveal New Understanding of Climate

Ancient rainfall records stretching 550,000 years into the past may upend scientists' understanding of what controls the Asian summer monsoon and other aspects of the Earth's long-term climate, reports a University of Arizona-led international team of researchers in the May 25 issue of the journal Science. The standard explanation of the Earth's regular shifts from

New theory finds ‘traffic jams’ in jet stream cause abnormal weather patterns

The sky sometimes has its limits, according to new research from two University of Chicago atmospheric scientists. A study published May 24 in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like

Major shifts in global freshwater

A new global, satellite-based study of Earth’s freshwater distribution found that Earth’s wet areas are getting wetter, while dry areas are getting drier. The data suggest that this pattern is due to a variety of factors, including human water management practices, human-caused climate change and natural climate cycles. The NASA-led research team, which included Hiroko Beaudoing,

Jobs in renewable energy hit 10.3 million last year, report finds

Over 500,000 new jobs were generated by the renewable energy industry last year, a 5.3 percent rise when compared to 2016, according to a report. The number of people working in the renewable energy sector — including large hydropower — hit 10.3 million in 2017, the International Renewable Energy Agency (IRENA) study said. The world's

America Should Invest In Distributed Renewable Energy Instead Of Natural Gas Plants, Finds RMI Report

Half of all existing conventional electricity generating plants in the US will need to be replaced by 2030 as they reach the end of their useful life. The question is, what should they be replaced with? The Rocky Mountain Institute has studied this question and concluded that investing in distributed renewable energy makes the most
