Tackling Climate Change with Machine Learning

arXiv.org Artificial Intelligence

Climate change is one of the greatest challenges facing humanity, and we, as machine learning experts, may wonder how we can help. Here we describe how machine learning can be a powerful tool in reducing greenhouse gas emissions and helping society adapt to a changing climate. From smart grids to disaster management, we identify high impact problems where existing gaps can be filled by machine learning, in collaboration with other fields. Our recommendations encompass exciting research questions as well as promising business opportunities. We call on the machine learning community to join the global effort against climate change.


Multi-agent Reinforcement Learning Embedded Game for the Optimization of Building Energy Control and Power System Planning

arXiv.org Machine Learning

Most of the current game-theoretic demand-side management methods focus primarily on the scheduling of home appliances, and the related numerical experiments are analyzed under various scenarios to achieve the corresponding Nash-equilibrium (NE) and optimal results. However, not much work is conducted for academic or commercial buildings. The methods for optimizing academic-buildings are distinct from the optimal methods for home appliances. In my study, we address a novel methodology to control the operation of heating, ventilation, and air conditioning system (HVAC). With the development of Artificial Intelligence and computer technologies, reinforcement learning (RL) can be implemented in multiple realistic scenarios and help people to solve thousands of real-world problems. Reinforcement Learning, which is considered as the art of future AI, builds the bridge between agents and environments through Markov Decision Chain or Neural Network and has seldom been used in power system. The art of RL is that once the simulator for a specific environment is built, the algorithm can keep learning from the environment. Therefore, RL is capable of dealing with constantly changing simulator inputs such as power demand, the condition of power system and outdoor temperature, etc. Compared with the existing distribution power system planning mechanisms and the related game theoretical methodologies, our proposed algorithm can plan and optimize the hourly energy usage, and have the ability to corporate with even shorter time window if needed.


The two key reasons the world can't reverse climate emissions

MIT Technology Review

Global energy demand and related carbon emissions both rose again in 2018, according to new figures out this week. This comes as no surprise. The analysis from the International Energy Agency is in line with other preliminary reports from other organizations. But it raises an awkward question: if renewables are growing and the prices of solar, wind, and batteries are falling, why is the world's climate pollution still going up? The first answer is the growing global economy, which pushed energy demand up by 2.3% last year, the IEA says.


A Hierarchical Genetic Optimization of a Fuzzy Logic System for Flow Control in Micro Grids

arXiv.org Artificial Intelligence

Bio-inspired algorithms like Genetic Algorithms and Fuzzy Inference Systems (FIS) are nowadays widely adopted as hybrid techniques in commercial and industrial environment. In this paper we present an interesting application of the fuzzy-GA paradigm to Smart Grids. The main aim consists in performing decision making for power flow management tasks in the proposed microgrid model equipped by renewable sources and an energy storage system, taking into account the economical profit in energy trading with the main-grid. In particular, this study focuses on the application of a Hierarchical Genetic Algorithm (HGA) for tuning the Rule Base (RB) of a Fuzzy Inference System (FIS), trying to discover a minimal fuzzy rules set in a Fuzzy Logic Controller (FLC) adopted to perform decision making in the microgrid. The HGA rationale focuses on a particular encoding scheme, based on control genes and parametric genes applied to the optimization of the FIS parameters, allowing to perform a reduction in the structural complexity of the RB. This approach will be referred in the following as fuzzy-HGA. Results are compared with a simpler approach based on a classic fuzzy-GA scheme, where both FIS parameters and rule weights are tuned, while the number of fuzzy rules is fixed in advance. Experiments shows how the fuzzy-HGA approach adopted for the synthesis of the proposed controller outperforms the classic fuzzy-GA scheme, increasing the accounting profit by 67\% in the considered energy trading problem yielding at the same time a simpler RB.


Japan to Solarize Its Burgeoning Digital Economy, Expert Take

#artificialintelligence

Society is now witnessing the implementation of digital currencies, artificial intelligence (AI) and blockchain technology worldwide. These new digital technologies necessitate very high consumption of electric energy, which is currently produced with coal and fossil fuels that have adverse environmental effects. A global shift toward green energy will require the removal of the technological/infrastructural, financial and regulatory/tax-policy barriers. In this series, we evaluate the tax, digital technology and solar policies (including a space solar power satellite) of the top carbon dioxide-emitting countries. In 2009, Japan -- the Land of the Rising Sun -- undertook important initiatives that set the tone for how it intended to solarize the world's third-largest digital economy.
