Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists have developed a first building block for photonic 'transistors' ...

The ever-increasing use of wireless devices, such as mobile phones, computing, and remote sensing systems, have led to increased demand and dependence on the use of batteries. Currently, most ...

As the first energy circuit rider, Melissa Elander helped transform Stratford with a wide range of energy-efficient and renewable energy projects. (Courtesy photo) When she began her new job in 2019, ...

The global demand for green energy sources is driving strong market growth for solar power systems. Although a great deal of development work is still focused on making PV (photovoltaic) energy ...

Non-volatile bistable memory circuits pave the way for highly energy-efficient CMOS logic systems. Non-volatile bistable memory circuits being developed by Satoshi Sugahara and his team at Tokyo Tech ...

Ultracapacitors (or supercapacitors) have become a primary energy-storage option for designers. Of late, power-IC makers are stepping up with ultracapacitor-specific circuits that address cell ...

Bob Pisani is off; this post was written by CNBC producer Robert Hum. Progress Energy was halted for 5 minutes due to single-stock circuit breaker rules at 12:57pm ET. But were those circuit breaker ...
