(Tokyo University of Science) Plastic waste often ends up in river bodies and oceans, posing a serious threat to the marine ecosystem. To prevent the accumulation of plastic debris, we must find out where plastic emission is prevalent. To this end, scientists in Japan have come up with a new method to track plastic emissions from inland areas to sea. This method is useful to identify the 'hotspots' of plastic emission and can even help to implement appropriate measures to avoid plastic pollution.

In recent years, multi-access edge computing (MEC) is a key enabler for handling the massive expansion of Internet of Things (IoT) applications and services. However, energy consumption of a MEC network depends on volatile tasks that induces risk for energy demand estimations. As an energy supplier, a microgrid can facilitate seamless energy supply. However, the risk associated with energy supply is also increased due to unpredictable energy generation from renewable and non-renewable sources. Especially, the risk of energy shortfall is involved with uncertainties in both energy consumption and generation. In this paper, we study a risk-aware energy scheduling problem for a microgrid-powered MEC network. First, we formulate an optimization problem considering the conditional value-at-risk (CVaR) measurement for both energy consumption and generation, where the objective is to minimize the loss of energy shortfall of the MEC networks and we show this problem is an NP-hard problem. Second, we analyze our formulated problem using a multi-agent stochastic game that ensures the joint policy Nash equilibrium, and show the convergence of the proposed model. Third, we derive the solution by applying a multi-agent deep reinforcement learning (MADRL)-based asynchronous advantage actor-critic (A3C) algorithm with shared neural networks. This method mitigates the curse of dimensionality of the state space and chooses the best policy among the agents for the proposed problem. Finally, the experimental results establish a significant performance gain by considering CVaR for high accuracy energy scheduling of the proposed model than both the single and random agent models.

Pooled computer resources. Grid computing, or simply grid, is the generic term given to techniques and technologies designed to make pools of distributed computer resources available on-demand. Grid computing was originally conceived by research scientists as a way of combining computers across a network to form a distributed supercomputer to tackle complex computations. In the commercial world, grid aims to maximize the utilization of an organization's computing resources by making them shareable across applications (sometimes called virtualization) and, potentially, provide computing on demand to third parties as a utility service. When used with specifications such as WSRF and WS-Notification, grid resources can appear as web services within a service-oriented architecture.

Ingrid Newkirk isn’t sure exactly how many times she has been arrested. “Definitely a few dozen,” she’ll say, if you ask. I’ve just done exactly that, so right now the British-born founder of People for the Ethical Treatment of Animals (PETA) is running me through a sort of greatest hits of her law-baiting exploits and the jailtime they have brought her in the name of animal rights.

Today, solar power has become cheaper than the production cost of any other existing conventional power generation technology. The arrival of grid parity heralds a milestone in the history of energy production. It means solar energy being commercially viable without any subsidies or state support; producing energy with the lowest possible environmental impact.

Given the diverse benefits that microgrids provide – reductions in energy costs, business risk, and carbon emissions, and increases in resiliency and power reliability – one wonders why discussion of microgrids has only started to take off recently.

Energy generation and consumption is rapidly transforming into a decentralized, decarbonized, and digitized model due to a number of market forces. The declining costs of solar energy systems, as well as the increasing price of energy from the grid has led to grid parity. This has caused PV proliferation to accelerate to such an extent that in the past five years alone, PV installed capacity has increased by 300%. Simultaneously, the EV market is also on the rise and is expected to reach the electrification tipping point by 2030. This is due to support from governments trying to limit the effects of climate change, thus leading to automotive manufactures transitioning their fleets from standard petrol- and diesel-powered cars to EVs. As a result of the acceleration of both of these markets, EV charging has created demand patterns causing an even steeper and faster ramp-up in the evenings than the PV duck curve. , This is causing the grid’s balancing act to be increasingly complex. In order to support this new energy dynamic, advanced management software is required to ensure grid stabilization and to unlock the value of these energy resources.

Yesterday, National Grid, through its competitive non-regulated unit National Grid Ventures (NGV), completed its $100 million acquisition of Geronimo Energy - a wind and solar developer in North America.

A pale orange-and-gold sunset bathes the macadamia plantations and avocado orchards that sweep down to Australia’s Byron Bay. The coming dusk is a cue for two sleek Tesla battery packs in the garage at Amileka, a secluded holiday villa nearby. They stir silently into action—powering the appliances in the five-bedroom home’s twin kitchens, recharging a $100,000-plus Model X SUV, driving a filter pump for an 18-meter swimming pool sparkling in the shade of a century-old native black bean tree.
