Hydro is the most widely used renewable energy in the mix, accounting for 16% of power generation, followed by wind (4.8%) and solar (2.2%). In Europe, nuclear energy is the dominant source, accounting for more than 70% of power generation. Wind and solar power combined account for just over 13%, which although small
Solar and wind are already proving they can replace fossil fuels as the main source of our electricity, but what they can’t do (yet) is provide the fuel at enough scale to decarbonise heavy end users like the transport sector. Hydrogen and fuel cell technologies are where a significant part
Concentrated solar power (CSP) is an approach to generating electricity through mirrors. The mirrors reflect, concentrate and focus natural sunlight onto a specific point, which is then converted into heat. The heat is then used to create steam, which drives a turbine to generate electrical power. The process can be
In short, intermittent generation is the irregular availability of electricity over a certain time period. When weather conditions are less than favourable, the efficiency of renewable sources decrease, which can make electricity generation inconsistent and unreliable. Since leading renewable technologies like solar, hydro, wind and geothermal power are weather dependent,
The transfer of energy through empty space is not new. The sun has been practicing this procedure for more than 4.5 billion years. But the losses are gigantic; Most of the energy radiated by the sun is lost in space, and only a tiny fraction reaches the celestial bodies that
AI devs are being stymied by an industry-wide shortage of GPU capacity at server farms, The Information reported, with Amazon Web Services, Microsoft, Google, and Oracle all limiting access. AI development is heavily dependent on graphics processing units (GPUs), which offer parallel processing that helps power through machine learning workloads at
On Nov. 24, 2021, an Alibaba Cloud Security engineer noticed that a certain string of text, when inserted into Java’s logging utility Log4j, could execute remote code. Cue the alarms, as vendors, security experts, and end-users spread the word about the hole in the massively used software, including US Secretary of Homeland
Perhaps it’s no surprise that former Navy pro Jeffrey Wells puts cybersecurity advice in nautical terms: You can’t defend the ocean. You can control your small part of it, however. Mechanisms like allowlists, said Wells, permit only a select set of IT-approved applications, not every single boat in the deep blue
The agency’s Denver office made the announcement in a tweet on April 6. “Avoid using free charging stations in airports, hotels, or shopping centers,” the tweet reads. “Bad actors have figured out ways to use public USB ports to introduce malware and monitoring software onto devices.” The tactic, known as “juice jacking,”
