Machine Learning has greatly contributed to the improvement of energy efficiency. By analyzing large amounts of data, machine learning algorithms can identify patterns and insights that humans may miss. This allows for more precise predictions and better decision-making regarding managing energy usage. For example, machine learning can be utilized to optimize heating, ventilation, and air conditioning systems in buildings, leading to significant energy savings. It can also help to identify areas of energy waste and suggest strategies for reducing consumption. Overall, machine learning has the potential to revolutionize the way we use energy and achieve a more sustainable future.
