Scientists find the factors behind rechargeable battery decay

Rechargeable lithium-ion batteries don't last forever. After enough cycles of charging and recharging, they'll eventually go kaput, so researchers are constantly looking for ways to...

Lunar soil could generate oxygen and fuel, shows study

Soil on the moon contains active compounds that can convert carbon dioxide into oxygen and fuels, scientists in China report in the journal Joule. They...

New tandem solar cells deliver record efficiency of 29.2%

EPFL scientists in Neuchâtel have developed a tandem solar cell that can deliver a certified efficiency of 29.2%. This achievement was made possible by combining...

Elon Musk: Why Tesla builds gigantic battery factories

Tesla’s mission is to accelerate the world’s transition to sustainable energy through increasingly affordable electric vehicles and energy products. To ramp production to 500,000 cars...

Most California incentive programs meant to reduce energy use have the opposite effect, shows...

The state of California spends about $1 billion per year on programs that subsidize the installation of energy-efficient appliances, from lightbulbs to whole-house retrofits. But...

Elon Musk: My view about Tesla competitors in the self-driving car market

The automotive industry is witnessing a rapid evolution of safety features, which is expected to increase exponentially in the coming years to provide a...

Reversible fuel cells could offer cheap energy storage

A major challenge for producers of electricity from solar panels and wind turbines is akin to capturing lightning in a bottle. Both solar and wind...

Cheaper solar cells could be soon on the market

Traditional solar cells are made from silicon, which has good efficiency and stability, but is relatively expensive to make and can only be manufactured...

Scientists reveal how lithium’s narrow paths limit batteries

If you could shrink enough for a fantastic voyage across a lithium battery electrode, you’d see the level of charge at every scale is...

New solar cells set world record efficiency: 24%

Scientists have developed a tandem solar cell that reaches 24 percent efficiency. This sets a new world record as the highest efficiency achieved so far...
