It has never been clearer that collaboration is absolutely essential to success in the energy transition, and to the climate action mission more broadly.
And while technology has revolutionised the way communication happens nowadays, it is also clear that in-person meetings are still the best way of fostering partnerships, sparking innovation and building the kind of trust that is necessary for organisations to engender systemic changes.
In recent years, energy conferences and summits have acted as the crucibles in which these big decisions are made and where pacts are forged.
More than ever before, policymakers, industry leaders, investors and innovators are attending these live events as they look to address the most pressing challenges of our time.
These events can help to facilitate decarbonisation, scale renewable technologies and ensure that energy security can be established around the globe.
With the world racing to meet its net zero targets, these events are imbued with an unparalleled significance. In this week's Top 10, Energy Digital shines a light on some of the most important energy-related events taking place this year.
