Are we using less energy because of LED lighting, or more?

It is wholly a confusion to suppose that more efficient lighting leads to diminished consumption. The very contrary is the truth. LEDs use a lot less energy per lumen produced; according to IHS Market, a consultancy, LED lighting uses an average of 40 percent less power than fluorescents, and 80 percent less than incandescents, to produce the same amount of light. They determined that "the use of LEDs to illuminate buildings and outdoor spaces reduced the total carbon dioxide (CO2) emissions of lighting by an estimated 570 million tons in 2017. This reduction is roughly equivalent to shutting down 162...

Weak links in US power grid vulnerable in event of catastrophe

In July 2012 India experienced the largest power outage in history. More than 620 million people were left without electricity after a transmission line in the northern part of the country failed, buckling under too much electrical load. Nearby power lines that took up the slack also failed, and lights across 22 Indian states went out. All power grids are at risk of this rare domino effect, called a cascading failure, and pinpointing which parts of the grid are most vulnerable could prevent future costly blackouts. Takashi Nishikawa at Northwestern University in Evanston, Illinois and colleagues modelled this risk in...

This new battery runs on seawater

There have been so many new approaches to batteries lately that it's hard to keep track of them all, but most of them have one thing in common: they are all cheaper and safer than lithium-ion batteries. Listen, lithium-ion batteries are the best we've got on the market right now. They can store a lot of energy in a small, lightweight package -- that's why they're in basically everything we own -- but they also have some drawbacks. The materials needed to make them aren't earth-abundant, which makes them more expensive, especially as you scale up in size. They are...

Man Solves Tesla’s Secret To Amplifying Power By Nearly 5000 Percent

Jim Murray has been electrifying the world for over 50 years. His lifetime of experience has produced dozens of patents, inventions and now a truly remarkable discovery that can fundamentally change the way that human beings use energy forever. When he was just five years old, Jim tells the Free Thought Project that he had already developed an affinity for motors and electricity. This curiosity was piqued by his father’s model train sets which Jim spent hours tinkering with. His natural gift and childhood passion fostered the creation of his first electromagnet when he was only six years old. Over...

Offshore Wind Arrives in U.S. Waters

NEW ORLEANS—The first offshore wind farm in the United States is set to begin delivering power to Rhode Island’s electricity grid by year’s end, a milestone that could help reshape energy markets from New England to South Florida, experts say. But for U.S. offshore wind power to achieve its full potential, as much as 4 gigawatts of capacity, it will need a major influx of capital and know-how, much of which will come from Europe, where the technology has a 25-year performance record and now accounts for 11 GW of generation capacity on the continent. Representatives of top U.S. and...
