    Engineers: your decisions shape our energy future

    By Richard Wallace | February 5, 2017

    “The politicians have done their job; now it’s up to the engineers.”

    That sentiment – first expressed by Jeffery Sachs, the director The Earth Institute of Columbia University, following the signing of the Paris Agreement – is resonating with engineers worldwide.

    The Paris Agreement calls for the world to limit global warming to less than 2 degrees Celsius (°C) compared to pre-industrial levels, and its political unity reflects a broad consensus on addressing climate change.

      Guest Blog: Calculating the accuracy of a battery fuel gauge

      February 2, 2017

      battery fuel gauge

      By Onyx Ahiakwo

      A battery fuel gauge obtains data from the battery to determine how much juice is left. Do not misconstrue gauging accuracy for measurement accuracy. A gauge’s ability to accurately report state of charge (SOC) and predict remaining battery capacity depends on measurements including voltage (‘V’), current (‘I’) and battery temperature (‘T’).

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

        January 23, 2017

         

         

         

        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.

          The notion of smart home has been making headlines for many years, but it’s actually the energy efficiency part where homes are making the most tangible gains through what designers call inverterization of appliance designs.

          Take the case of home appliances like air conditioners and ceiling fans.

            Chipmakers warming up to 48V datacenter movement

            By Majeed Ahmad | January 19, 2017

            With the emergence of 48V datacenter architecture on the server rails, is there a greener cloud on the horizon in 2017? A lot depends on the availability of chips that can efficiently facilitate the 48V single conversion to the point-of-load (PoL) while providing the projected 16x reduction in distribution loss and 30 percent lower conversion loss.

              From smartphones to automobiles and the electric grid, energy storage is becoming more critical. For mobile devices, the need is clear for safe, longer-lasting, energy-dense chemistries. For automobiles, the move to hybrid, electric, and autonomous vehicles has increased the bounty to be had for denser and lighter storage.

                The Internet Of Things 2017: one analyst’s outlook

                January 13, 2017

                The full impact of major technological shifts play out over years, if not decades.
                When the Internet spilled over from its roots in research into the business realm, people were certain – and concerned – that Internet commercialization would inevitably change the nature of the Internet itself.

                Years on, people had it all wrong. Commerce did not change the Internet – the Internet in fact, completely upended and changed the world of commerce – and it continues to do so at an accelerating rate – throughout the world.

                  China powers up $360 billion renewable energy future

                  We’ve all seen the images from Beijing, millions of residents chocking on dirty yellow smog. It’s the result of China’s dependency on coal as a primary fuel – something the current government plans to attack in a bold energy initiative focused on solar, wind and other renewable sources.

                  The goal is to curb greenhouse gases, a plan that will create 13 million jobs and pump $350 billion into China’s economy between now and 2020 according to the New York Times.
