Four things that matter more than the Paris Agreement

In a new report, “Undiplomatic Action: A practical guide to the new politics and geopolitics of climate change,” David Victor and Bruce Jones write:

“Without confidence in new technologies and the policy and investment support that follows from that confidence, even the most advanced and elaborated global diplomatic agreements can only produce an ever-wider chasm between stated goals and realistically achievable outcomes.”

They contend that “real world” actions on the ground, not global goals, will drive energy transitions at the local level and in the private sector.

In the paper, they outline four key factors they believe matter even more than the global agreement:

  1. Facilitate leadership through small groups
  2. Focus on near-term emissions reductions
  3. Invest in technological innovation
  4. Demonstrate success and enable better governance

Leading The Charge: As Battery Storage Sweeps The World, GE Finds Its Place In The Sun
By Tomas Kellner – The “duck curve” has two distinct peaks — one in the morning and the other after sunset — connected by a sagging belly pulled down by the deluge of renewable energy generated by the millions of solar panels sprinkled across California’s roofs and fields.

On a sunny Sunday, this glut of input could even lead to oversupply, a situation where wholesale energy prices drop so much that producers pay utilities to take their energy.

The problem reverses when the sun sinks into the Pacific. Power producers must quickly crank up their plants – many of them burning gas or coal – to replace those missing solar electrons with 11,000 megawatts to keep the state’s homes and businesses humming.

“The peak for solar power generation is at noon,” says Eric Gebhardt, vice president of strategic technology for GE Power. “What if you could store this energy and release it six hours later when the sun goes down and people come home, start cooking dinner and watch TV?” Gebhardt asks.

That’s precisely the point of GE’s Reservoir, a new grid-scale energy storage system the company unveiled today. The grid has to be perfectly balanced, meaning that power supply and demand match, to prevent it from crashing.

The Reservoir will allow producers to “decouple when energy is produced and when it is consumed,” Gebhardt says. “Without it, if you have too much solar during the day, the only option you have is to curtail production.”

The rise of the electric car unleashed innovation in the battery space, and the spread of solar power has brought costs down 50 percent over the last four years, says Keith Longtin, product breakout leader at GE Global Research in Niskayuna, New York. “You are now getting to a point where energy storage starts to make sense,” he says. more>

What is Fiber Densification?
By Helen Xenos – The term “network densification” is being used more often in relation to wireless network deployments, and more recently, “fiber densification” has become a hot a topic of discussion. So, what exactly is densification?

Densification simply describes the goal or end state of supporting more capacity within the same area or footprint. It is borne from the need of network providers to not only keep up with the increase in bandwidth demand they are seeing, but also grow their competitive edge in delivering a better end user experience for their customers.

Cable or Multi-Service Operators (MSOs) are undergoing a multi-year upgrade of their Hybrid Fiber Coax (HFC) access infrastructure. To provide a better quality of experience to subscribers, they are delivering higher capacity to smaller groups of homes and pushing fiber closer to the edge of the network.

HFC Fiber nodes, which on average service 500 homes per node, are being replaced with 10 to 12 Digital Fiber nodes. These nodes will now service 40 to 64 homes, be pushed deeper into the access, and increase per-user capacity.

An incredible amount of digital fiber nodes are expected to be deployed in the next few years, from tens to hundreds of thousands globally in 2018 and 2019. Fiber densification, the ability to pack as much capacity as possible over the limited fiber resources available, is of critical importance to achieve business objectives.

Finally, the simplest example of fiber densification is the hyperscale data center interconnect application. Global content providers are deploying huge amounts of fiber between massive data centers to maintain their aggressive pace of innovation and keep up with the doubling of bandwidth they are seeing on a yearly basis. more>

Head for the Hills with Kopernikk

By Charles Purdy – A love of the outdoors is plainly evident in Kopernikk’s photography, and he comes by it naturally, having grown up on a farm near the Czech city of Pardubice, which he still calls home—that is, when he’s not on the road for a photography expedition. In fact, it was a 2014 trip to the Czech Republic’s Giant Mountains that set Kopernikk firmly on a path to making his living as a photographer.

He remembers, “In November 2014, my friend Jirka invited me to Špindlerův Mlýn in our Giant Mountains. The weather was so magical—I was like Alice in Wonderland, and I made hundreds and hundreds of photos on my mobile phone…. This day changed everything, and I knew then what I wanted to do with my life. It’s also the reason I have Sitka, my Czechoslovakian Wolfdog—I’ve always loved wolves, and when I started traveling I decided I wanted to have my own ‘wolf’ as a travel buddy.” more>
