Two-thirds of Africa’s population still don’t have access to electricity

Africa is booming. I feel it every time I land in Nairobi, Accra and Lagos. Hotels are filled to the brim and the energy on the streets and boardrooms is tangible. The rest of the world is at long last starting to take note. But the true potential of millions of Africans is still being

Tesla’s Business Model More Similar To Amazon’s Than You Think

Tesla is more than just a car company. According to Miriam Tuerk at Forbes, “The electric-car company is working to decentralize power distribution and offer an alternative to today’s utility… Tesla is demonstrating that if the challenge goes unmet by traditional power utility companies, they’ll have their lunch stolen.” Tesla first took on the auto industry, “reinventing

Template to create superatoms, created by VCU researchers, could make for better batteries

Virginia Commonwealth University researchers have discovered a novel strategy for creating superatoms -- combinations of atoms that can mimic the properties of more than one group of elements of the periodic table. These superatoms could be used to create new materials, including more efficient batteries and better semiconductors; a core component of microchips, transistors and

‘Elegant’ design could lead to more powerful, safer lithium metal battery

Chemical engineering professor Lynden Archer believes there needs to be a battery technology “revolution” – and thinks that his lab has fired one of the first shots. “What we have now [in lithium-ion battery technology] is actually at the limits of its capabilities,” said Archer, the James A. Friend Family Distinguished Professor of Engineering in the

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

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

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

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

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

New polymer manufacturing process saves 10 orders of magnitude of energy

Makers of cars, planes, buses – anything that needs strong, lightweight and heat resistant parts – are poised to benefit from a new manufacturing process that requires only a quick touch from a small heat source to send a cascading hardening wave through a polymer. Researchers at the University of Illinois have developed a new

Engineers upgrade ancient, sun-powered tech to purify water with near-perfect efficiency

The idea of using energy from the sun to evaporate and purify water is ancient. The Greek philosopher Aristotle reportedly described such a process more than 2,000 years ago. Now, researchers are bringing this technology into the modern age, using it to sanitize water at what they report to be record-breaking rates. By draping black,

Energy-efficient light bulbs cost more in high-poverty areas

Energy-efficient light bulbs are more expensive and less available in high-poverty urban areas than in more affluent locations, according to a new study. Researchers explored disparities in the availability and price of energy-efficient bulbs by surveying 130 stores across Michigan’s most populous county. They found that the cost to upgrade from a conventional incandescent bulb

Pulling valuable metals from e-waste makes financial sense

Electronic waste — including discarded televisions, computers and mobile phones — is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it’s been unclear whether it’s reasonable from an economic viewpoint. Now researchers report in ACS’
