US utility Dominion Energy has filed grid modernization plans with the Virginia State Corporation Commission.

A European cybersecurity pact has been agreed that is intended to make “the tools of the energy transition safe for citizens and secure for providers”.

The Nevada National Security Site (NNSS) inaugurated the Mercury Solar Project late last month and moved it further down the path of sustainability, giving NNSA its first net-zero-energy building.

A report released this month by PricewaterhouseCoopers (PwC) indicates hydropower development in India can play a crucial role in the country’s sustainable energy security if sites for new installed capacity -- among other things -- are accessible, stable and affordable.
 

In a previous article, I had a conversation with former-CIA chief Jim Woolsey to discuss one of America’s greatest national security vulnerabilities, its power grid. The issues that Woolsey has been concerned with for over a decade has been the ease in which a terrorist group or other actor (think North Korea for example) could attack the grid and plunge the country into darkness for months, if not years. And if that seems far-fetched, just recall how a tree limb fell in Ohio in 2003 and blacked out the entire Northeast and part of Canada for several days.

When you think of superheroes, you probably picture capes and some sort of otherworldly powers. But in the digital world, superheroes are actually normal people like you and me. They just happen to know a thing or two about stopping cybercriminals in their tracks.

These superheroes are in short supply across the world. In fact, there are over half a million cybersecurity job openings in the U.S. alone. That just means this could be your chance to swoop in, superhero style, and save the day. But first things first, you need to learn the ropes and the Ultimate 2020 White Hat Hacker Certification Bundle is a great place to start. Read more...
