Electricity is the most versatile and widely used form of energy and global demand is growing continuously. Generation of electrical energy is, however, a major source of carbon dioxide emissions, making a significant contribution to climate change. To mitigate the consequences of this, the current electricity grid needs to undergo a big shift.
A considerable amount of future electricity will come from renewable energy sources, reducing dependence on fossil fuels and lowering emissions in the long run. These renewables need to be integrated into grids that are able to manage new complexities such as intermittent supply, more distributed power generation, demand management and electric vehicles. So, the evolving power system needs to be increasingly flexible and interconnected, as well as more reliable and intelligent – what we need, in short, is a stronger, smarter and greener grid.
