    Germany hits record production in renewable energy marathon

    In record-breaking weekend, Germany got 85% of its electricity from renewable energy sources

    May 30, 2017

    The sports world is driven by athletes relentlessly driven to deliver their personal best, no matter what the contest.

    Generating renewable energy is reaching a similar level of competitiveness among conservation-minded nations. Witness Germany’s setting of a national record in renewable energy production on a recent weekend in which 85 percent of all electricity consumed was produced through wind, solar, biomass, and hydroelectric power.

      Bluetooth low energy: Control LED color and brightness with a smartphone

      By Majeed Ahmad | March 27, 2017

      Bluetooth mesh networking and beacon functionality are now allowing smart lighting startups like PURillume to simplify installation complexity, reduce energy consumption, and automate lighting controls merely by using a smartphone or a tablet.

      PURillume’s LED lamps for hospitality and residential markets can be color tuned wirelessly using Bluetooth low energy (BLE) encrypted connections from a master lamp, smartphone or tablet.

        Smart lighting and the makeover of LED driver ICs

        By Majeed Ahmad | February 7, 2017

        LED driver ICs such as Fairchild’s FL77944 accommodate higher wattage systems like street lights using parallel connections with LEDs.

        American Airlines Center near the Dallas downtown recently replaced the high-pressure sodium and metal halide light fixtures with LED luminaires in its parking garages. And that has allowed the sports and entertainment arena to reduce an estimated 60 percent energy consumption and $1.26 million in total lifetime savings in parking garage lighting.

          Guest Blog : How the IoT — and the smartphone — are enabling the smart home

          A smart home in San Diego, California combines the best of modern architecture with the best in smart home technology.

          Providing a comfortable space for its occupants is only the minimum requirement for a habitable building, whether it be a primitive shelter, or modern steel and glass structure.

          A building should be more than just a “container” for its occupants.

            Edison’s revenge? Why DC-only distribution makes sense for energy savings

            By Patrick Mannion | January 2, 2017

            The drive for energy conservation, the DC basis of modern electronic systems, and the development of renewable energy sources have converged to challenge the 100-year-old assumption that AC alone is the single best means of distributing electricity.

            Instead, a combination of AC for the main grid and DC for micro and nano grids is shaping up to be a more energy-efficient path, if industries and engineers come together to define the necessary standards and implement them effectively.

              The rise of energy-efficient microcontrollers

              By Majeed Ahmad | January 2, 2017

              The humble microcontroller — also the workhorse of embedded design — has long been battling the dilemma of how to raise the performance bar while conserving energy. A new generation of MCUs is finally turning a corner on energy-efficiency challenges while offering greater processing horsepower for high-end embedded designs.

              Case in point is ST Micro’s STM32H743 microcontroller that boasts the ARM® Cortex®-M7 core running at 400MHz.

                Solar inverter: Before and after GaN

                The inherent low switching losses of the GaN power stage make it possible to reach efficiencies of 99% and higher. Higher efficiencies mean smaller heat sinks and less need for cooling, and facilitate designs that are more compact and very cost-effective

                  How engineers can stop climate change in its tracks

                  The goal of the Paris agreement can be met by more efficient use of energy

                   

                  ei

                  In December 2015, after two decades of negotiations, 195 countries adopted a historic, legally binding agreement on climate change. The primary goal of the so-called Paris agreement is to hold the increase in global average temperature “to well below 2°C,” and “to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change.”

                  The agreement still needs to be approved by the individual governments of the countries involved.
