New York City plans to support electric vehicle (EV) adoption with a $15 million initiative to install 600 new curbside chargers. Can the city’s current grid infrastructure keep pace? New York City is ramping up its efforts to support electric vehicle (EV) adoption as it plans to install 600 new curbside EV chargers. Mayor Eric Adams recently announced that the initiative is part of a $15 million federal grant being awarded to the city to bolster its EV charging infrastructure — with a focus on underserved and low-income communities. “We’re building a cleaner, greener, and more affordable city for all New Yorkers, and through initiatives like this, we’re making sure that no New Yorkers are left behind,” wrote Mayor Adams in a blog post. “This $15 million grant will let us build the nation’s largest EV charging program, focused on low-income and disadvantaged areas so people living in all five boroughs can afford to drive and charge electric vehicles.” By 2050, New York City aims to get 20% of all new vehicles registered as electric. Thanks to incentives like the Inflation Reduction Act tax credits and Drive Clean rebates, a growing number of NYC drivers are switching to EVs. Despite these efforts, the city's grid is already struggling to keep up with the power and infrastructural requirements of current EV owners. Can NYC’s Electrical Grid Keep Up with the Growing Demand for EV Charging? NYC is currently grappling with two key challenges to scale its charging infrastructure — space and available power. For commercial transportation, charging hubs require significant space for infrastructure and larger electric trucks. In dense urban areas, especially NYC, real estate is limited and expensive, making it difficult to find suitable locations to accommodate charging stations and vehicles without disrupting city traffic. “Most of the federal EV infrastructure grants are for chargers deployed along highways (not buildings), limiting monetary incentives available to building developers deploying EV chargers,” Akshay Singh, Industrial and Automotive Industries Principal at PwC Strategy&, told me. “City planners need to work closely with utilities to make sure upgrades are being planned & performed timely, especially to supply dense urban areas with the highest EV adoption.” New York’s grid is already strained as the city attempts to electrify not only its transportation but also its buildings. Singh asserts that developers often do not understand the level of grid upgrades required due to a lack of available information. Moreover, these challenges are expected to become more prevalent with charging sites located in high-rise buildings that have not had capacity upgrades in years. “Major challenges with EV charging today are around how to make the economics of operating EV chargers feasible. DC fast chargers that operate at 100kW+ power output (to charge EVs within 30-45 mins) can cost upwards of $50k per unit which makes upfront costs of a multi-unit charging site very expensive,” added Singh. Electric Vehicles as Untapped Grid Assets? As New York pushes toward its ambitious goal of having 400,000 EVs on the road by 2030 as part of the "Green Rides" initiative, it’s clear that the city needs more fast-charging sites. Conglomerates like Revel are already making strides with its "superhub" in Brooklyn, boasting 25 high-speed chargers. But even with their success, the company faces a significant challenge: finding enough grid power to keep these large fast-charging stations running smoothly. While the city grapples with its grid limitations, some startups are stepping in to offer innovative solutions through A.I. and edge computing. Brooklyn-based Synop, for instance, aims to help stabilize the grid by integrating data from grid operators, EV charging stations, and EV fleet operators. “We focus on edge computing to enhance charging management,” Gagan Dhillon, CEO of Synop, told me. By bringing cloud-based functionality closer to the charging site, the company says it can increase reliability and reduce latency, “which is critical in areas with constrained grids or complex microgrid setups.” Dhillon added that one overlooked aspect of EV adoption is that electric vehicles are essentially batteries on wheels, and with the right infrastructure, they can serve as valuable assets rather than just power consumers. “EVs can act as backup power sources during times of high grid demand, providing energy back to the grid or even powering homes when needed,” he said. “With the integration of smart charging technology, EVs can be programmed to charge during off-peak times when energy is more abundant. This flexibility makes them less of a strain on the grid than often imagined.” With more people driving EVs and a grid under a lot of strain, NYC's EV goal success will hinge on how open it is to new technologies, speeding up infrastructure projects, and investing in sustainable energy solutions. “There will be a need for higher powered EV chargers that will further increase the grid upgrade requirements. Developers need to work together with local utilities from the start to successfully deploy EV projects,” Singh told me. “Along with that, additional [capital expenditure] needed to sustain the grid for more demand needs to be laid out and discussions on who will bear the cost burden.” New York City plans to support electric vehicle (EV) adoption with a $15 million initiative to install 600 new curbside chargers.

NYC's $15 Million EV Charger Initiative: Can the City Grid Handle Rising Energy Demands?

It’s no secret we've stumbled upon a formidable obstacle to our AI-powered future: the staggering energy consumption of our current models. Industry leaders are scrambling to come up with short-term answers to ensure they don’t miss the wave, with ambitious efforts like Microsoft’s reopening of nuclear reactors on Three Mile Island and Google working on “first-of-its-kind” geothermal projects. And while that plays out at the big kid’s table, a flock of new startups are building on the progress made in recent years, re-thinking the fundamentals to see if there are solutions that could serve as the long-term solution. One that doesn’t require hundreds of millions of dollars in infrastructure investment. AI’s Power Demands Are a Ticking Time Bomb Operating large language models in their current iteration is an energy-intensive process that's rapidly approaching unsustainable levels. Training a single AI model can emit as much carbon as five cars over their entire lifetimes. It's not just an environmental concern; it's a scalability nightmare threatening to derail the AI revolution before it fully takes flight. Consider these sobering facts: GPT-3, with its 175 billion parameters, reportedly required 1,287 MWh for a single training run.
The carbon footprint of training a large NLP model is estimated to be around 626,000 pounds of CO2 equivalent.
As models grow, so does their energy consumption – often at a superlinear rate. And as the industry pushes for more advanced AI capabilities, this energy consumption is set to skyrocket. This is not only a problem on an operational level but also in the greater picture, as industry leaders like Google have pledged to achieve net-zero carbon emissions through the purchase of carbon credits from firms doing things like plugging orphaned oil and gas wells - a market where demand is already far out-pacing supply. Efficiency & Minimal Parameter Activation: The New North Star of AI Innovation The solution may be rather simple: smarter, smaller, more efficient models built for a set of specific purposes. Narrowing the scope, if you will. One such example is the open-source Aria model built by Rhymes, which employs minimal parameter activation. While the Aria model boasts a total of 25.3 billion parameters, it only activates a mere 3.9 billion for any given task. Traditional, mainstream models like GPT-3 activate all of their parameters for every task, regardless of complexity, while Aria's approach is like a surgeon using only the necessary instruments for a specific procedure. Many surgeons would tell you they don’t need to deploy the entire operating room's worth of equipment for every operation. Rhyme has deployed this in practice with BeaGo, which they call “a smarter, faster AI search.” Based on my tests, BeaGo’s results were indistinguishable from competing products from Perplexity and other, most energy and time-intensive products. But it’s more than simply narrowing the scope: the startup has built a multimodal open-source mixture-of-experts model that sorts and intelligently manages large, long-context data of all types, including text, video, and images. Rhymes’ solution may be lighting the pathway for AI in 2025 and beyond, all without the hundreds of millions of dollars in infrastructure spending. The Reminder: Innovation Never Stops In the end, the work of companies like Rhymes serves as a reminder that just because we found something that works, doesn’t mean the task of innovating is over. While Microsoft and Google run with our existing large language models, working to productize and bring AI to the mass-market, others cannot stop working on building something even better. I’m heartened by the startup-driven approach that I see here at the end of 2024 – combining multimodal capabilities, selective parameter activation, and open-source collaboration – offers a blueprint for how we can achieve a vision of an AI that both works and works for the planet.

It’s a real shame that I couldn’t get a ticket to one of the landmark events that solidified London’s status as a hub of concentrated creative energy. This year, those who harness this energy – the ones who still burn with the desire to make the world a better place – used it to raise public awareness on a wide range of issues. At the London Design Festival, themes of synergy between nature and humanity took center stage, embodied in the work of Marjan van Aubel. Hot on the heels of her installation, the industrial design team at Diez Office encouraged an unspoken dialogue about ecological responsibility with their project Vert. In general, the program featured numerous innovative solutions, breaking down the boundaries of stereotypical thinking. And we crave that kind of intellectual stimulation! In this piece, I’ll talk about the playful, mesmerizing, light-hearted and literally warming design on display this year! London and design go hand in hand. It is part of our story. London Design Festival is a platform for hundreds of design stories to be told. Each of them speaks to an expanding audience hungry for design ideas and enjoying the quality and diversity of what’s on offer. It all confirms London’s status as the global center of design – says Ben Evans CBE. It’s hard to disagree with the words of this passionate advocate and activist for all-encompassing creativity, which can be found in everything that surrounds us. Today, we’ll spot it in glass, but in a broader sense, we’ll explore the role materials play in design – and in parallels. Parallels not only between the red oak beams of the exhibit at Chelsea College of Arts but also between the architecture of play and real life. The Sun, My Heart The energy within us has the power to create incredible things, especially when we learn to recognize it and channel it in the right direction – one where we create something extraordinary that captivates the world. Energy is the central theme in the work of Dutch designer Marjan van Aubel. Her creations can hardly be described as merely "sunny" although, in reality, each one of them is filled with light. Without this element, we can no longer imagine her work. Energy, as an aesthetic element, has become an integral part of every object crafted by her hands: from glassware, which reflects the flow of matter, to entire installations. We, in turn, have become vessels filled with her revelation: They were transparent and colored. It was the first time I saw that solar energy could be beautiful. From that moment, I started implementing it into different objects: glassware, tables, light installations, buildings. Now, I see all surfaces as a potential to harvest energy Speaking of installations, we can now explore her piece “The Sun, My Heart” a highlight of the LDF collection. The title becomes somewhat rhetorical when you consider van Aubel’s relationship with the primary source of life, with roots that delve deep into Buddhist philosophy. In the language of Vietnamese monks, it calls on us to "open our hearts to new connections". These connections come to life through 77 self-charging Sunne lamps (some of which represent nothing more than rays of light), symbolizing the complete solar cycle, accompanied by harmoniously selected sounds that echo the sun's vibrations. Working in unison, this masterpiece immerses the viewer in a state of total relaxation, stimulating the brain's theta waves. We receive the sun in such abundance. It’s obvious that we need to transition to solar energy, but the current approach is too technical. We shouldn’t only talk about numbers and efficiency. The sun is something holistic; we can feel it. We need beauty and design to make us want to change things. We need to feel it inside – the designer shares. Pavilions of Wonder A fresh perspective with a historical undertone, embodying cultural heritage – the true American dream, brought to life in a trilogy of works by designer Nina Tolstrup. This project has become a symbol of vivid imagination and aesthetics, driven by a spirit of fun and playfulness. The installation consists of three objects, harking back to the time when Palm Springs became the true capital of modernism in the USA, owing to its ability to "grow rapidly" with affordable housing after World War II. This area, dotted with buildings of the corresponding architectural style, would later become a prototype of inspiration for future designers. Among those designers is Nina Tolstrup, who infused the project with the same playful spirit reflected in Barbie’s DreamHouses. It is through her vibrant qualities, captured like film on a reel, that we recognize the essence of the designer. We looked at the evolution of the DreamHouse, informed by Greater Palm Springs architecture. We examined the visual language and iconic elements common to both Vert And here are the very same "parallels" made from red oak, presented in the collaborative work of the American Hardwood Export Council (AHEC), the Munich-based Diez Office, and Frankfurt's Office for Microclimatic Cultivation (OMC°C). This project is far from a cry for help, but rather a message of mindful care for the environment. Vert, which signifies something "green" is an undeniably bold statement, offering a tangible and effective solution to a global issue. It represents a solution through a small, carefully planned, and meticulously thought-out noble endeavor. It can't be achieved just by planting trees or through individual façade and rooftop greening projects, so additional solutions are urgently needed. We need fairly large structures to generate the necessary amount of shade and biomass – explains Nicola Stattmann, co-founder of OMC°C. The architectural installation consists of several triangular structures, each standing 10 meters tall. These are all covered with plants such as morning glory, cheese plant, black-eyed Susan, and night-blooming moonflower, which will act as "killers" of carbon dioxide released into the atmosphere. Interestingly, the modularity of the designed structure allows for Vert to be produced in series in the future. This once again highlights the brilliance of the minds behind the project, brought to life with the support of AHEC, who have long been advocating for the use of durable engineered materials. Red oak glulam's natural beauty, combined with its structural capabilities, makes it a promising choice both functionally and aesthetically – says Stefan Diez, Diez Office founder. The London Design Festival 2024 masterfully demonstrated the power of design in tackling global issues – from sustainable energy solutions to supporting biodiversity and reimagining urban spaces. Through innovative projects, the festival highlighted the crucial role of creativity in shaping a more sustainable and harmonious future. As these projects blur the lines between functionality and beauty, they invite us to envision a world where technology, nature, and human ingenuity coexist seamlessly, encouraging a more thoughtful and responsible approach to life. The London Design Festival week was one of the most anticipated events for us. Our fields are closely intertwined – that much is clear. We keep track of the latest trends to make our 3D visualizations even more realistic, filled with the smallest details that reflect the quality of bringing the 'imagined' to life. We’re interested in everything: from the materials often used in designers' projects to the very concepts behind these works, because this knowledge embodies our commitment to staying current. We don't want to fall behind. We aim to build trust with every client interaction, ensuring that the result meets and exceeds their needs, leaving them fully satisfied – says Alexander Kasperovich, CEO of 3D visualization and rendering studio, Studio57.

Minutes Network Closes In On Its First 1.2 billion Users With Smart Energy Water

As global awareness of environmental impact intensifies, industries across the board are being called upon to adopt sustainable practices. The cryptocurrency sector, particularly Bitcoin mining, has come under fire for its excessive energy consumption, which is often powered by fossil fuels. In a bold move to address these concerns, Digital Holdings Group is setting a precedent by significantly integrating renewable energy sources into its operations. Establishing a Greener Footprint Digital Holdings Group, established in 2017, has not only expanded its presence globally but also its commitment to environmental stewardship. The company operates mining facilities in North America, Europe, and Asia, with a substantial portion of its energy consumption sourced from renewable energies like solar and wind. This shift is not just a nod to environmentalism but a strategic adaptation to the growing regulatory and social pressures facing the mining industry. The decision to switch to renewable sources is backed by compelling data. According to the Bitcoin Electricity Consumption Index by Cambridge University, the Bitcoin network consumes more electricity annually than some countries. By transitioning to renewables, Digital Holdings Group not only mitigates its environmental impact but also stabilizes its long-term operational costs, as renewable energy prices are less volatile compared to fossil fuels. Leveraging cutting-edge technology, Digital Holdings Group has developed highly efficient mining rigs that reduce electricity usage without compromising performance. This technology, combined with renewable energy, significantly lowers the carbon footprint per Bitcoin mined. Additionally, the company is exploring energy storage solutions to handle intermittent energy supply, ensuring consistent mining operations regardless of weather conditions. With an ambitious goal to power 80% of its operations with renewable energy by 2025, Digital Holdings Group is not just transforming its own business model but also setting new sustainability benchmarks for the cryptocurrency mining industry. This initiative could catalyze a shift towards greener mining practices globally as competitors and new entrants look to emulate Digital Holdings Group's strategy. The move towards renewable energy has garnered support from various stakeholders, including investors who are increasingly prioritizing environmental, social, and governance (ESG) criteria in their investment decisions. Customers and partners are also showing a strong preference for companies with responsible environmental practices, enhancing Digital Holdings Group's brand reputation and market position. Digital Holdings Group's integration of renewable energy into its Bitcoin mining operations signifies a pivotal shift in the industry’s approach to energy consumption. By prioritizing sustainability, the company not only enhances its operational efficiency and compliance with global regulations but also contributes to the broader goal of reducing the ecological footprint of digital currencies. As the industry evolves, Digital Holdings Group’s proactive steps may well inspire a new standard for environmental responsibility in cryptocurrency mining.

Coupling Dark Energy to Neutrinos
Impact of the Coupling on Perturbations and Observables

Discussion
Acknowledgment, Appendix, and References II. COUPLING DARK ENERGY TO NEUTRINOS Let us consider a flat universe with vanishing curvature, spatially homogeneous and isotropic, whose expansion is parameterized by the scale factor a associated with the Friedmann-Lemaˆıtre-Roberson-Walker (FLRW) spacetime metric. Further considering that the expansion is sourced by photons (γ), baryons (b), cold dark matter (c), neutrinos (ν) and a scalar field dark energy (ϕ) responsible for the current acceleration, the Friedmann equation reads In this study, we want to test a possible interaction between neutrino species and dark energy, in a mass-varying neutrino model where active neutrinos are coupled to the scalar field [13–20]. Because to leading order cosmological data are only sensitive to the total neutrino mass [36, 37], we assume for practical purposes [38] two massless neutrinos and a massive neutrino non-minimally coupled to the quintessence component. The coupled neutrino has a varying effective mass, which depends on the value of the scalar field and on a dimensionless and constant parameter β, The stress energy tensors of the neutrino fluid and the scalar field are not conserved separately. We have where pϕ is the pressure in the field. The extra source terms vanish without interaction, β = 0, or if the massive neutrino particles are ultrarelativistic, behaving as traceless radiation. To test the model with observations, we adopt a known phenomenological parametrization, first proposed in Ref. [22], where the scalar field depends linearly on the number of e-folds, N ≡ ln a, throughout the cosmological evolution. We introduce a dimensionless constant λ for the slope of the scaling: This simple approach is a powerful alternative to the popular CPL parametrization [40, 41], since a large variety of dark energy equation of state evolutions can be captured by just one additional parameter [42], thereby limiting the degeneracies in Bayesian inferences. An additional advantage is that the scalar field potential can be reconstructed analytically following Ref. [22, 24–26]. This is done by solving the first-order differential equation (2.7) to find ρϕ using the constraint equation (2.1) and noting that ϕ˙ = λH according to Eq. (2.9). The potential happens to be a sum of exponential terms, where the mass scales are given by the following analytical expressions, We can see from Fig. 2 that the coupling with neutrinos changes wϕ during the matter-dominated era. For growing masses (β > 0, dotted line), the field equation of state is smaller compared to the uncoupled case (β = 0, solid line). On the contrary, wϕ is larger when the energy transfer occurs in the opposite direction, i.e. from neutrinos of shrinking mass (β < 0, dash-dotted line). Correspondingly, Fig. 3 shows that the non-relativistic neutrinos which receive energy from the scalar field (β > 0) have lower fractional energy density to reach the same present mass than when they give energy (β < 0). with where ϵ is the neutrino comoving energy.
