U.S. power grid operator PJM, the nation's largest covering much of the East Coast and Midwest, on Friday ordered customers in emergency alert to curb their use, as it battled generator outages, overloaded transmission lines and surging air-conditioning demand during a prolonged heat wave.
PJM Interconnection, which manages the electricity system serving 67 million people in 13 states and the District of Columbia, has issued emergency energy alerts amid expectations that hot summer weather will drive up power demand.
The 13 states are Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia.
The firefly converts 98 percent of the energy it consumes into light—whereas the efficiency of modern LED lights is only 50 percent. Interesting text!
Hey Rediators-
Lately, there's been a ton of talk about blending ethanol into petrol and diesel. The government says it's a game-changer with minimal impact on car performance, according to new research. But a lot of car makers are saying their vehicles, right down to the smallest parts, aren't built for ethanol mixes.
What do you all think about this?
Just wanted to share whats happening in Germany right now because I feel like the rest of the world doesnt really know about it. We have this thing called Balkonkraftwerk which is basically a plug and play solar panel you stick on your balcony, 800W max feed in. Theres now like 3 million of these installed and the storage market is exploding because people realized they produce way more than they use during the day. The interesting part is the new regulations keep the 800W feed-in limit but panel input can go well beyond 2000W now, some systems take up to 5.000 Wp of panels, so with storage you can capture everything the panels make and use it at night. Brands are competing hard right now on capacity, cycle count, smart features. Some are doing 5kWh single units, others are modular. Its like the early days of powerwall but for apartments
