Solar goes up on a rooftop in Nevada
NRDC and SolarCity have published a new analysis on costs and benefits of rooftop solar energy in Nevada that shows it’s benefitting all utility customers in the state and benefits could significantly increase under good solar policies.
The results of the paper, coauthored by Dylan Sullivan, show
Jim Ahlgrimm has been a manager in the U.S. Department of Energy Wind and Water Power Technologies Office since 2002
When the U.S. Department of Energy (DOE) commissioned a 1.5-megawatt (MW) wind turbine in 2009, it became a key player in our research to improve the performance and lower the costs of wind energy systems. In 2015, researchers at the National Wind Technology Center (NWTC) near our National Renewable Energy Laboratory
A diagram of the spectrum-splitting, four-junction mini-module developed at UNSW
A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device.
The record was set
At this year's Intersolar exhibition KOSTAL is introducing two new functions for three-phase PIKO string and battery inverters. A new shadow management feature, part of the PIKO smart optimisation concept, ensures maximum yield from partially shaded PV systems, providing better flexibility.
the Energy Department announced five additional military bases will join Solar Ready Vets, a solar jobs training program that prepares service members for careers in the solar industry when they leave active duty. The Department is also awarding $10 million to 10 new projects through its Solar Training and Education
The U.S. Department of Energy announced up to $10 million in funding for six projects representing innovative technologies and solutions to advance bioenergy development. These projects, located in Arizona, California, North Carolina, Delaware, and Illinois, will support the Bioenergy Technologies Office's (BETO)
The Power Electronics Industry Collaborative (PEIC – pronounced peak) announced that Oak Ridge National Laboratory (ORNL) has joined its growing list of members working together to accelerate innovation and advocate for investment in new power electronics technologies.
“We are excited to be joining
In this PSDcast Dr. Ranbir Singh, founder of GeneSiC, talks to Alix Paultre of Power Systems Design about their position and products in the wide-bandgap semiconductor space. GeneSiC is a pioneer and little-known IP leader in Silicon Carbide technology, and their Silicon Carbide Junction Transistor (SJT)
As coal dependence falters in the U.S., wind-powered electricity generation is on the rise. In less than a decade, the mix of fuels used for generating electricity has gone a major shift. Twelve states, most of them in the wind-rich Great Plains or the upper Midwest, are getting more than 10 percent of their
Solliance demonstrates a record 10% aperture area power conversion efficiency for its up-scaled thin-film perovskite photovoltaic modules. The efficiency was measured on an aperture area of 168 cm2. Twenty-five cells were serial connected through an optimized P1, P2, P3 interconnection technology. The PV module
Overvoltages and the associated high surge currents can damage, or even destroy electrical and electronic devices. Reliable overvoltage protection is therefore essential. On the basis of a new ceramic material, TDK has now developed a high-surge series of multilayer varistors that combine compact dimensions
Part 1 of this article provided an overview of TT Electronics’ AEC Q200 qualified and certified transformers, which are optimized for use with a gate drive optocoupler to improve and simplify the design of isolated power supplies. This introduction looked at the theory of operation and how this impacts on
In the age of the ‘Internet of Things’ (IoT) economy, smartphones are replacing hotel keys, and facilities managers (FM) are beginning to notice the reward in using big data to monitor customer behavior in hotels, shops and restaurants, as well as monitoring employee engagement and wellbeing in offices.
Isolated power supply systems are prevalent in server systems, industrial applications, and telecommunication and networking equipment. In this bandwidth-hungry age of the Internet of Things (IoT), a growing number of these systems need to be efficiently powered, driving up the need for power-efficient, cost-effective
Now more than ever, the blooming of the Internet of Things (IoT) has been putting emphasis on the longevity of battery life. Every IoT node demands a battery to operate. A household of two people can have anywhere from 20 to 60 batteries in use at any time, and consumers can’t be burdened with the need to
Being a Sci-Fi geek, I am a fan of the late 1950’s Hollywood “cheesy” low budget Ed Wood movies typical of this genre. One of my favorite films is “Plan 9 from Outer Space,” in which aliens come to Earth to stop humanity from building a doomsday weapon that could destroy the entire universe. However,
The term “hot swap” refers to the practice of inserting or removing modules from a powered system. Hot-swap controllers are sometimes categorized together with power distribution switches; however, there are key differences that must be understood for proper system design. A hot-swap controller uses an external
Materials are needed to replace the estimated 50,000 metric tons of tin-lead solder currently used each year, but there are no "drop-in" replacements for eutectic tin-lead solder. $1.2 billion of electrically conductive adhesives (ECAs) are already selling each year, and they are becoming increasingly
