This Is The World's Most Efficient Black Silicon Solar Cell

Solar power is getting much, much better. Now, a team of scientists has created the world’s most efficient nanostructured black silicon solar cell — which converts an impressive 22.1 per cent of incident light into electricity.


This Could Be The World's Most Efficient Solar System

A Swedish company claims that this small-scale concentrated solar energy system — which leans on ideas from a 19th-century Scottish clergyman — converts 34 per cent of sunlight into electricity. That could make it the most efficient solar system in the world.


Here's How Much Energy We Waste On Cat GIFs And Twitterbooks

Are you sitting comfortably? Good, because you’re about to get a good old-fashioned dose of guilt. The folks at SciShow have put together a video examining how much energy we waste on running the internet, and the number is embarrassingly large.


The Beginning Of The End For Fossil Fuels

While wind and solar power have made great strides in recent years, with renewables now accounting for 22% of electric energy generated, the issue that has held them back has been their transience. The sun doesn’t shine at night and the wind doesn’t blow year-round — these are the mantras of all those opposed to the progress of renewables.


Tesla's Gigafactory Isn't Big Enough For Its Battery Orders

As Elon Musk revealed in an earnings call earlier this week, heaps of people preordered Tesla’s new batteries — over 50,000 Powerwall units were reserved. Now some interesting maths, courtesy of Bloomberg: The 465,000 square metre Gigafactory planned outside of Reno probably isn’t big enough to make them all.


The Future Of Energy Is Hidden In The Guts Of Insects

This presentation from Berkeley Lab scientist Javier Ceja-Navarro hints at a strange new future for agriculture and energy production. I’m willing to bet it’s like nothing that you ever imagined.


Tesla Battery Economics: On The Path To Disruption

Elon Musk announced Tesla’s home / business battery last week. tl;dr: It will get enthusiastic early adopters to buy. The economics are almostthere to make it cost effective for a wide market. And within just a few years, it almost certainly will be cheap enough to be cost effective for a broad market. Not a complete game changer today, but a shot fired in an incredible energy storage disruption.


How Tesla's Powerwall Stacks Up To Regular Energy, By The Numbers

I think about big, cheap batteries for a living, so I stayed up late and listened to the Tesla announcement. My first thoughts: These are fantastic prices for an uninterruptible power supply — but they’re still expensive as day-to-day electricity.


Farmers Without Water In The US Are Installing Solar Panels Instead

Due to the unprecedented drought, many of California’s farmers won’t be allocated any water this year, thanks to the way that the state’s water rights work. But what actually happens to the farms that don’t get water? Some of the farmers are ditching produce altogether for a more profitable alternative to crops — they’re installing solar farms.


Tesla's New Battery Could Solve One Of Solar Power's Biggest Problems

So far, specific details are thin on the new battery designed for home use that Tesla’s announcing next week. But just based on what we do know, it’s a pretty big deal. The quest for a good battery that can store home-generated power is kind of like the holy grail for a renewable energy future. This one product might change everything.
