EU-funded researchers have developed a cloud-based platform to reduce energy use in buildings and battery energy storage systems to benefit end users and utility providers. Climate change is driving Europe to transform its energy sector. As we transition from a fossil-based to a zero-carbon economy in the next few decades, we will use more renewable energy, and the electricity we generate won’t come from a central plant. Instead, it will come from multiple, decentralized renewable energy sources that are near to load demands. But is the existing networking capable of hosting this increase in capacity? And how would the electrical grids of the future work?
