Despite significant achievements in sustainable energy innovation and market scaling of technologies such as solar, wind energy storage and others, the rate of change is not fast enough. Considering two thirds of Greenhouse Gas emissions are from energy, and demand will continue to grow up to 35% by 2040, a wider spread of technologies and solutions need to be matured for commercial deployment, at a much faster pace. This whitepaper builds on insights from dialogue events and expert interviews. It highlights the critical role of good policies, funding mechanisms and alliances to increase investments and enable the energy innovation ecosystem to prosper, as well as proposing new 'bold ideas' which, if effectively implemented could trigger a significant step change in innovation for sustainable energy.
