Using a Blockchain for a Smarter Energy Grid

Blockchain technology stems from Bitcoin and provides a platform for change greater than Bitcoin itself. Researchers in the renewable energy industry have realized that blockchains can be used to replace outdated billing and tracking. Presently when a company produces energy it requires verification form other companies and each step eats into profits – a more efficient system would be use blockchains to verify the system by cutting out the middleman. The blockchain also provides a transparent solution that makes for easier monitoring and accountability than what’s currently provided.

The blockchain being used the example below is powered using my favourite cryptocurrency Ethereum. It is another way that distributed ledger systems mixed with computing power can alter our economies for the better.

Keeping track of renewable-energy certificates is one of dozens of potential applications of blockchain technology that could solve data management challenges in the electricity sector without disrupting business as usual, according to Morris. He and many others believe that in the long term, the technology could help transform the very architecture of the grid itself.

To unleash the potential of blockchain in the energy sector, Jesse Morris’s team at RMI has joined with Austria-based blockchain startup Grid Singularity to create a new nonprofit called the Energy Web Foundation. Earlier this month, the EWF launched its own blockchain, which Morris says is “purpose-built for the energy sector.” Based on Ethereum, the network will be a test bed for promising use cases. To validate transactions during the test, EWF will rely on 10 major energy companies that have signed on as affiliates.

Using Math to Solve for Inequality

Inequality has been increasing globally for years, and developed nations have seen inequality rise in rates comparable to the start of the great depression. This situation is understandably problematic and worrisome. Accordingly, a lot of thinkers have looked into the problem, most solutions come down to some level of redistribution of wealth. The New England Complex Systems Institute has used a complex math approach to conclude that tax cuts will only make the gap between the rich and poor worse. The solution is, indeed, wealth redistribution.

Bar-Yam and his colleagues’ new research shows that a purely monetary solution to the US economy’s current imbalance is insufficient. Bar-Yam likened this to trying to drive a car by focusing only on the gas and brake pedals, and ignoring the steering wheel. In addition to interest rate regulation, Bar-Yam’s research points to a transfer of wealth to the less wealthy sectors of society as the most effective way to rebalance the consumption and production cycles.

This conclusion is based on response theory, a way of looking at complex systems by changing the environmental conditions to see how the system responds. Bar-Yam and his colleagues analyzed historical data to create models that showed how the US economy responds when the distribution of wealth between the production and consumption cycles are altered. Their models demonstrated that the Trump Administration’s current approach to economic growth—cutting government spending while slashing tax rates for the rich—is misguided.

Good Health Stems from Walking, Biking, and Transit

Regularly walking and biking are good for one’s health, but did you know taking public transit is too? That’s right just by not taking a car to work like most North Americans you can be healthier. A simple life change can have a large impact on your life, plus by not using a car you can save the lungs of your neighbours and improve your city. Urban designers and doctors are starting to take this into consideration when talking about personal health and cities.

An efficient, affordable transit network is one key to better health. This can be as basic as a solid bus service, or can include a plethora of enhanced bus options and rail. Whatever the system, people who use transit “get more than three times the amount of physical activity per day than those who don’t,” just by walking to and from it, according to TransLoc – 19 minutes of exercise daily versus six minutes for those who don’t use transit.

Transit also reduces air pollution, making everyone healthier. Not to mention that city buses today often have cleaner engines than do cars.

Public transit also causes fewer accidents than individual cars, is far safer, is known to reduce stress, and improves the quality of life for vulnerable populations.

After Going Green, Cities Need Turn Blue

Cities need to work with their local ecosystems and not against them. This is evidently true when it comes to waste management and overt displays of green initiatives. There is a harder aspect of ecological thinking for cities and it’s usually beneath our feet: water.

Water systems are complex in every direction – getting drinking water in and storm water out. The way cities plan for water issues is more important than ever before as we enter a time of water scarcity and extreme weather. What we should be doing (and smart cities already are) is designing our urban spaces with the flow of water in mind.

“We need to acknowledge that the water is eventually going to do what the water wants to do, and shift our approach, as human populations living on the Earth, from one of trying to dominate nature to one that acknowledges the power of nature and works in synchrony with that,” says English. “We’ve already set ourselves down this path of dams and levees and water control systems, and it’s really hard to turn back. But we don’t need to keep replicating that. We don’t need to make the situation worse. It’s time to step back from the approach of control and fortification.”

“Cities that today start to embrace water and take advantage of the skills of water, will be the cities that have a better performance economically and socially and politically in 20 to 30 years,” says Koen Olthuis, founder of Waterstudio, a Dutch firm that has found designing around water to be more than a niche market. “When situations change—and that’s happening now, the environment is changing, the climate is changing—cities have to react. You have to change the skills and the performance of the city to give a reaction to this situation, and the reaction should be not fighting it, it should be living with it.”

Yes in my Backyard!


For too long cities have been plagued by NIMBYism – people who chant not in my backyard. People who oppose change have held back communities for too long and now people are shouting yes in my backyard – YIMBY. In Toronto the rise of this movement has led to annual event called YIMBY Toronto. The movement is international though and it’s primarily driven by people who have been negatively impacted by previous generations’ poor urban design choices. A whole generation is taking a negative and making it a positive.

The movement is fuelled by the anger of young adults from the millennial generation, many of whom are now in their late 20s and early 30s. Rather than suffer in silence as they struggle to find affordable places to live, they are heading to planning meetings en masse to argue for more housing – preferably the very kind of dense, urban infill projects that have often generated neighbourhood opposition from nimbys (“not in my back yard”).
