FOREWORD
We have no time. The window is closing and the pathway to a net zero future is narrowing. This was the message I delivered plainly and unambiguously when we released the World Energy Transitions Outlook preview at the Berlin Energy Transitions Dialogue earlier this year. Science is clear: 45% of global greenhouse gas emissions from 2010 levels must be reduced by 2030. Unfortunately, the recent trends show that the gap between where we are and where we should be is widening. We are on the wrong path, and we need to change the course now.
The choices we make in the coming years will have a far-reaching impact. They could bring us on a path toward the goals we set out in 2015 when we adopted the highly consequential international agreements on sustainable development and climate change. Or they could take us in the opposite direction to further warming, with profound and irreversible economic and humanitarian consequences.
It is unwise to make predictions or pre-empt outcomes at uncertain times. But several trends are shaping an unfolding energy transition and giving an indication of its direction. First, the costs of renewable technologies have plummeted to the point that new fossil-based electricity is no longer an attractive option. Second, the progress in the power sector is spilling over to end uses, allowing a re-imagining of possibilities with the abundance of renewable options at hand. Third, a consensus has formed that an energy transition grounded in renewable sources of energy and efficient technologies is the only way to give us a fighting chance of limiting global warming by 2050 to 1.5°C. Only a few years ago, the renewables-centred approach espoused by IRENA was considered too progressive, idealistic or even unrealistic. Today, our vision has become mainstream, and accepted as the only realistic option for a climate-safe world. And this is reflected in the growing number of commitments to net zero strategies by countries in all corners of the world, creating unprecedented political momentum for a transformative change.
IRENA’s World Energy Transitions Outlook outlines the avenues to take us out of the climate crisis toward a resilient and more equitable world. It clearly shows the options we have today and what gaps need to be filled. The analysis and options presented prioritise existing emission-reduction solutions and those with the highest chance to become viable in the coming years. It does not bet on unproven technologies or pending inventions but encourages much-needed innovation to perfect and advance the fastest path to emission reduction.
The Outlook offers a compelling path for decarbonising all energy uses, with electrification and energy efficiency as primary drivers, enabled by renewables, green hydrogen and sustainable modern bioenergy. But a scenario and its assumptions, however rigorous and comprehensive, are only an instrument to inform policy making. To translate this vision of the energy future into reality, we need to transcend the limits of the existing infrastructure created for the fuels of the past. And these decisions are not made in a vacuum. Economic and human development goals, environmental concerns, and financial avenues must all be reconciled.
It is in this context that IRENA brings its unique value.
The Outlook shows that, when we look beyond the narrow confines of energy supply, a renewables-based transition unlocks a range of valuable benefits. The Outlook thus presents the policy frameworks necessary to advance a transition that is just and inclusive. It provides an improved understanding of structural changes and offers a quantitative framework for impacts such as gross domestic product (GDP), employment and welfare. The report also examines funding structures to show the necessary shift in capital markets.
And this knowledge provides the basis for IRENA to support countries in realising their priorities and turning their strategies into action. With our 164 Members, we see how collective action can drive progress worldwide and where overarching needs and gaps may exist.
This global reach is what gives the Agency the credibility - and privilege - to support international co-operation across the gamut of energy transition issues to help countries learn from each other and tap into the vast expertise of the Agency. And we are actively working with partners, including the private sector, to provide a dynamic platform that drives action, foresighted planning, holistic policy making and investment at scale.
The demands of our time are great and full of uncertainty. We are entering a new era of change, one in which energy transformation will drive economic transformation. This change is bringing unprecedented new possibilities to revitalise economies and lift people out of poverty. But the task ahead is daunting. I hope that this Outlook provides a fresh view on how to turn today’s energy problems into tomorrow’s solutions.
Our shared future will only be bright if we move together, taking everyone along towards a more resilient, equal, and just world.
