South Africa to become wind energy hot spot (and why we should care)
As recently as 2012, South Africa had very little wind energy capacity—10 MW to be precise—and it had taken ten years to get to that point. Now, in 2016, it is right around 2 GW. That's something like a 1900% increase in four years by my (admittedly math-addled) brain. And according to Read More...
Chinese people want renewable energy more than anyone, but nobody’s selling it to them
It turns out a staggering number of Chinese people are willing to pay more for renewable energy. But businesses that sell green power to consumers, prolific elsewhere, haven’t yet got a single foothold in the biggest market on earth. A survey of 3,000 Chinese city-dwellers by Ipsos Mori, a Read More...
'Smart energy' revolution to balance electricity demand
A "smart energy" revolution could help ensure that the UK does not suffer blackouts, according to National Grid's new UK chief. Nicola Shaw, its executive director, said technological advances will reduce the need to build new conventional power stations in the UK. An "internet of energy" will Read More...
Why you'll be seeing a lot more electric cars on the road this year
Have you noticed more electric cars on the roads these days? How about an increase in electric charging stations or lanes dedicated to zero-emissions vehicles? If you have, it’s because the world is getting set for the transition to electric vehicles. The infrastructure to support such a Read More...
It’s not just solar panels. Electric cars can be contagious, too.
We already know that solar power can be contagious. Studies have found that if you install a rooftop solar system, it increases the odds that your neighbors will too. Now along comes tantalizing evidence that electric vehicles have a similar dynamic. When charging stations are more visible, people Read More...
Millions of used electric car batteries will help store energy for the grid. Maybe.
Once or twice a year, Bloomberg New Energy Finance (BNEF) founder Michael Liebreich posts a magisterial summation of some trend or set of trends in the energy world. His latest report is about electric vehicles. It’s worth reading the whole thing, but it was an aside about discarded EV Read More...
New solar powered device revives hydrogen economy dream
Despite a plethora of naysayers, research is progressing apace on deploying hydrogen as a sustainable fuel that also doubles as an energy storage opportunity. The latest development illustrates just how quickly that pace is accelerating. A research team based at Switzerland’s Ecole Read More...
Wave power is going to revolutionize renewable energy
There's enough wave energy in the oceans to power the world, and scientists are finally close to harnessing it. For decades wave energy has lagged behind wind energy and solar because harnessing it is more complex. However, the potential is huge: According to the U.S. Department of Energy, waves Read More...
Forget self-driving cars. Let’s make self-driving living rooms
The imminent arrival of the self-driving car will change how people move around city streets, but they could do so much more. The Tridika is a conceptual driverless electric vehicle I created to change how we use cars in our ever-growing cities, where space is expensive and limited. Inspired by Read More...
Renewables now provide 43% of new electricity capacity in U.S.
The grid continues to get cleaner and cleaner. Renewable energy accounts for a large percentage of new electricity generation capacity quarter after quarter in the United States, while old coal power plants close down quarter after quarter. However, due to the massive size of the electricity Read More...
