Democratization of energy

The ‘Chain-of-things IoT, Blockchain and Security Conference’, that took place in London on 1st June, saw the presentation of a full stack data-logger, that connects multiple blockchains to the digital output of solar energy plants.

“We think we are onto something here; by connecting a data-logger that grabs solar energy output in near-real time and then pushing that securely to multiple blockchains for different purposes we can help democratise energy wherever it is generated,” explained Luke Johnson, co-founder of ElectriCChain and CEO of Solcrypto.

The full-day event examined potential use cases for the full stack, and a two-hour ‘hackathon’ midway through the event allowed for the brainstorming of some wider use cases, with a $100 prize presented to the winner by the Intel Software - Code for Good initiative.

Representatives from Solcrypto, the company producing the node and data-logger software, Bitseed, the node manufacturer, and the SolarCoin Foundation, who distribute the SolarCoin digital token to incentivize solar power production, were present to discuss the solar power case study.

In addition, representatives from IOTA, a new type of blockchain 3.0 technology termed a ‘tangle’ that allows for direct machine-to-machine token discovery on a shared ledger seamlessly and efficiently, allowing for zero-fee microtransactions and quantum security, and the Chain-of-things (CoT) research laboratory, a research consortium for blockchain and Internet-of-things (IoT), were present.

Various speakers working in the IoT space also discussed the security, or the lack thereof, in the IoT space and “how blockchains could be employed to address the multiple attack vectors that have been hampering the development of the IoT industry throughout its history.”


“Trusted data about energy production and consumption is key to managing small grids and finance for the bottom of the pyramid,” says ElectriCChain.

ElectriCChain is the blockchain behind the SolarCoin digital asset. It helps to gather and publish non-confidential data related to solar owners for scientific (e.g. climate change), meteorological (e.g. weather/microclimate forecast), and financial (e.g. solar hedging/derivatives tools) applications.

It is aiming to deploy a network of over 7 million of these solar power-data-logger installations around the globe, according to IEA numbers, and exceed 200 million installations within 15-25 years.

However, co-operation is still ongoing as the data-logger transitions to a minimum viable product. Eventually, multiple blockchains could be integrated into the Bitseed node to serve different purposes, including interfacing with apps installed on the data-logger and with distributed apps written as smart contracts for Ethereum. The only limit to the number of blockchains that can be added to the stack is the size of the physical storage on the device and associated hardware.

Francois Sonnet, co-founder of ElectriCChain and solar industry veteran, says of the burgeoning solar power-blockchain collaborative industry:

“With Solar Energy, IoT and blockchains all on their own growth paths, we believe that this is a significant beginning to a new industry that could be phrased as ‘Blockchain-Energy’ with many applications from micro-finance of small solar home systems in developing countries to rewards based mechanisms for large scale solar plants to increase their return on investment.”

To fight climate change, we need to ‘Uberize’ the energy industry

Written by Hemant Taneja, Managing Director, General Catalyst Partners

Organizing capital, in isolation, isn’t enough to get hundreds of Elon Musks dedicating themselves to building companies that develop critical new wind, solar, nuclear and battery technology.

In June, I attended a breakfast organized by Energy Secretary Ernest Moniz and Bill Gates, with top business and policy leaders from around the world. The investors in the meeting were dedicated to increasing funding of early-stage energy companies. Of course, that’s a much-needed step. As the data below shows, exponential decrease in solar costs has led to exponential increase in solar capacity, despite limited technology investment. This has been principally driven by consistent, long-term policy that drove deployment at scale.

But while entrepreneurs recognize the importance of the mission and want to work on advanced energy, markets aren’t creating long-term opportunities to lure them. I’ve lived this myself. I started investing in this space a decade ago because entrepreneurs began moving in. I witnessed the market design problem companies ran into and created Advanced Energy Economy to help policy, technology and finance come together to create long-term markets. But persistent unwinding of policies made entrepreneurs give up and instead go into sectors that were more likely to pay off. Today, in Silicon Valley, I just don’t hear great entrepreneurs wanting to take on one of the most important challenges of our time.

Look at just one example of the market hurdles: earlier this year, regulators in Nevada gave in to push-back from NV Energy, and significantly dropped the price paid to homeowners who sell excess energy generated by their rooftop panels back to the utilities firm. The price drop was so damaging to solar customers that the nation’s biggest rooftop solar company, SolarCity, decided to pull out of the state. While technologies that could significantly reduce carbon emissions are within our grasp, the energy market conditions get in the way and slow progress.

Uber and Tesla show that when companies create amazing consumer experiences, large, fragmented markets can organize fast around a new solution. Customer adoption of Uber, the enthusiasm for Tesla electric cars, and advances in self-driving vehicles have brought the transportation sector to a point of no return. The days of internal combustion engine and gasoline are numbered. Just think about that: in less than a decade, cars running on electric power will be a utility that we can access on demand. Far fewer of us will own cars. The most in-demand new cars will be electric. That is an amazing step forward towards reducing CO2 in the atmosphere.

The swift change to electric-powered transportation makes it all the more important to transform the 21st-century electricity system. An effective way to do that will be to employ the lessons from Uber and Tesla and let entrepreneurs lead the established companies.

How? A crucial early step will be to align utilities with entrepreneurs instead of against them. Let’s create regulatory and business models that give utilities a path to evolve their role from operating mammoth power plants and transmission grids to operating software-powered platforms that interconnect the small-scale power solutions in homes and small businesses. This then becomes a platform that supports entrepreneurial solutions, much like the internet or the iPhone and app store. Utilities can prosper, providing reliability and resiliency in the power network, while faster-moving entrepreneurs create ever more effective ways to generate, move, trade, market, share and store power.

Entrepreneurs will come in hoards to tackle this great mission if they can take advantage of the economies of unscale that have propelled other sectors. Airbnb is an unscaled response to hotels, re-assembling demand for places to stay in a whole new way. The Honest Company took advantage of unscaling to profitably compete against Procter & Gamble in consumer brands.

Time after time, we’re seeing small companies win in established sectors by building on existing platforms and finding a new market. That’s what has to happen in energy. If the right technologies get developed, entrepreneurs will unscale the energy industry, turning it into an ecosystem of small companies and producers generating and moving power in a distributed way.

What can entrepreneurs do in the field of energy? One important role: solve the problem of power storage. A major barrier to unscaling electricity is that it can’t be stored effectively. Tesla and a number of global companies are racing to build affordable battery technology for homes and businesses. Once energy can be stored cost effectively in small quantities, much less of it needs to be produced centrally and distributed on power grids.

Put all of this together, and this is systems thinking about the problem. It follows market principles, centering solutions around what customers actually want. We need to bring to the power industry the same mindset we apply to internet-based “utilities” like Facebook and Google. After all, how are they any less important to life today than energy?

If we do this right, no utility will ever again build a large-scale carbon-based power plant. Such a thing won’t be necessary if every home is generating electricity on its roof and the grid works more like the internet, moving power to where it’s needed and storing excess in new-age batteries for reliable access. Just as anyone can now be a hotelier because of Airbnb, in a decade anyone will be able to be a power company once these new technologies are in place. In an unscaled era, the mini power plant in a home or small business will be better, cheaper, cleaner and more resilient than the next massive power plant.

Customers will have choices, and if new energy technologies are better, cheaper and cleaner than old ones, that’s what customers will choose. And this is what COSOL offers with its crowdfunding model and community solar farms throughout Brazil.
