PG&E provides electric service for approximately 16-million people in northern and central California. (Image credit: PG&E)   Several days ago, California’s electric utility provider PG&E (Pacific Gas and Electric) announced it would proactively cut power during days of strong winds and extreme fire danger in an effort prevent wildfires, as it’s widely believed overhead power lines were responsible for sparking last year’s deadly Camp fire. The intentional out ...
Hunstable Electric Turbine claims the same range on smaller batteries! (Image credit: HET)   Linear Labs, a family-founded company, run by father-and-son, Fred Hunstable and Brad Hunstable, have developed “a new class of electric motor” called the Hunstable Electric Turbine (HET). The duo promises their HET will, for the same size, weight, volume, and exact amount of input energy into the motor, always deliver two to three times torque output of any electric motor in the world. ...
Researchers discovered uranium ditelluride exhibits a rare phenomenon known as re-entrant superconductivity, making it a promising material for use in quantum computers. (Image credit: University of Maryland)   Researchers from the University of Maryland, NIST (National Institute of Standards and Technology), the National MagLab (National High Magnetic Field Laboratory), and the University of Oxford have observed an unusual phenomenon known as re-entrant superconductivity in uranium ditell ...
The researchers were able to synthesize a forbidden compound of cerium and hydrogen (CeH9), which demonstrates superconductivity at low pressures. (Image credit: MIPT)   Researchers from the US, Russia, and China have seemingly done the impossible by synthesizing a ‘forbidden,’ or ‘impossible’ compound, known as cerium superhydride (CeH9), that exhibits superconductivity at low pressure. Superconductors are capable of conducting an electrical current with little to ...
Researchers from Australia National University (ANU) have set a new record for solar cell efficiency, reaching a rate of 21.6%, the highest amount ever recorded for a perovskite solar cell measuring 1cm². This means that 21.6% of sunlight converts into energy when it hits the cells. It’s an impressive boost in efficiency for solar cells when taking into account that solar panels being installed on rooftops in Australia have an efficiency rate of 17-18%. The results were independently ...
The Powerhouse Brattørkaia has an eye-catching design. (Image credit: Ivar Kvaal/courtesy Snøhetta)   A new landmark building recently opened in Trondheim, Norway and it may be a leap forward in renewable energy. Snøhetta’s Powerhouse Brattørkaia is a new sustainable office building that’s been dubbed as the most “energy-positive” building in the world. By using numerous solar panels, it produces more than double the amount of electricity it cons ...
Typically, car batteries can last for up to five to six years, which would then need to be replaced, but sometimes sooner, if they get worn out quickly and easily. Engineers working for Tesla are aiming to change that. They claim to have developed batteries that could power a vehicle for up to a million miles, which can be run for over a decade.   Tesla’s new battery could be equipped into existing electric vehicles, giving them a boost in battery power.

By 2050, nearly half of the world’s electricity will be supplied by solar and wind, effectively putting an end to energy created by coal and gas. Owners of EVs will also be able to hook up their automobile to a power grid, transferring energy back and forth between cars and houses, allowing car owners to carry renewable energy wherever they go.   However, it requires storage battery systems. Switching from a system that supplies energy through power plants running on fossil fuels to ...
On July 18th, New York’s governor, Andrew Cuomo granted contracts for two offshore wind projects based off Long Island, expecting to reach 1,200 megawatts in capacity. The deal is the largest for offshore wind power in U.S. history, and it’s a vital part of the plan to get all power emissions-free by 2040. Equinor ASA and a joint venture between Denmark’s Orsted A/S and Massachusetts Eversource Energy were awarded the opportunity to construct the farms, creating enough energy t ...
A new study shows the rise of renewable energy and how close it is to dethroning nuclear energy. Renewable energy is growing at a fast pace. Will it be the main source of energy in the future? (Image credit: gong hangxu/iStock)   As concerns about global warming and climate change grow, the call for renewable energy keeps growing. A new article from Forbes tracks the rise of renewable energy around the world. Their findings show that while coal is still the main source of electricity aroun ...
As an engineer, I expect about 10% of everything will fail. Imagining having to fix 320,000 solar panels sounds rough...   On June 29th, the world’s largest solar plant project with 3.2 million solar panels installed across an 8-kilometer site, the Noor Abu Dhabi became fully operational, with a capacity of 1,177MW. There are also differences between this project and a ‘solar park.’ A solar park is usually an area of land marked to harness solar power and usually boast mu ...
Tesla’s secret lab in Freemont, California is currently in the process of developing battery cells. Present and former employees of Tesla have made reports on recent developments, with plans to manufacture them into their own electric vehicles. The company is dependent on Panasonic to develop battery cells at the moment and may affect future production roles, especially since Tesla signed a partnership deal with Panasonic in 2014.   Tesla’s secret battery could cut costs, ad ...
Scottish Power has announced plans to undergo a massive power project in Europe to harness UK’s wind and solar farms. The company will be connecting a massive battery, half the size of a soccer field, to the Whitelee onshore windfarm in early 2020 to acquire more power from its 215 turbines.   Scottish Power’s newest battery will help to power UK and can help with any small power fluctuations. (Image Credit: Danny Lawson - PA Images via Getty Images)   This project will ...
  The demand for electric vehicles has exploded, but supporting infrastructure still has a long way to go to realize the vision of a fossil-fuel-free world.   When is the last time you’ve seen an electric vehicle charging station? If you’re like most Americans, it has probably been a while. That is going to have to change to support the anticipated 3 million electric vehicles (EV) expected to be on the road by 2025.   Image: International Council on Clean Trans ...
The Powerpack units allow trains cutbacks on energy consumption and can be used as a backup power generator if an outage occurs. (Image Credit: Tesla)   Tesla's latest installation of their Powerpack units in Osaka, Japan invites backup power to trains in the region. Installation included 42 Powerpack units that will help to reduce peak energy demands on the grid. If an outage were to occur, trains and passengers would still be able to travel to the nearest station due to the functionality ...
