Wind turbines and solar panels are the physical signs of consumers’ growing desire for clean, renewable energy. Connecting the new power sources to our grid, bundling and transporting the electricity, is much more complicated than it used to be. Looking ahead, we will also be investing in digital technologies, including creating a central “data hub” that can help to manage the many different ways we will be able to source  electricity.
