Renewable Energy Can Deliver 86% Of Global Power Demand — IRENA

Renewable Energy Can Deliver 86% Of Global Power Demand . As the urgency to take bold climate action grows, new analysis by the International Renewable Energy Agency (IRENA) finds that scaling-up renewable energy combined with electrification could deliver more than three quarters of the energy-related emission reductions needed to meet global climate goals.

According to the latest edition of IRENA’s Global Energy Transformation: A Roadmap to 2050, pathways to meet 86 per cent of global power demand with renewable energy exist. Electricity would cover half of the global final energy mix. Global power supply would more than double over this period, with the bulk of it generated from renewable energy, mostly solar PV and wind. The roadmap was launched at the Berlin Energy Transition Dialogue which held recently, from April 9 to 10, in Germany.

“The race to secure a climate safe future has entered a decisive phase,” said IRENA Director-General Francesco La Camera.

“Renewable energy is the most effective and readily-available solution for reversing the trend of rising CO2 emissions. A combination of renewable energy with a deeper electrification can achieve 75 per cent of the energy-related emissions reduction needed.”

A release by the agency has it that an accelerated energy transition in line with the Roadmap 2050 would also save the global economy up to USD 160 trillion cumulatively over the next 30 years in avoided health costs, energy subsidies and climate damages. Every dollar spent on energy transition would pay off up to seven times. The global economy would grow by 2.5 per cent in 2050. However, climate damages can lead to significant socio-economic losses.

But action is lagging, the report warns. While energy-related CO2 emissions continued to grow by over 1 per cent annually on average in the last five years, emissions would need to decline by 70 per cent below their current level by 2050 to meet global climate goals. This calls for a significant increase in national ambition and more aggressive renewable energy and climate targets.

IRENA’s roadmap recommends that national policy should focus on zero-carbon long-term strategies. It also highlights the need to boost and harness systemic innovation. This includes fostering smarter energy systems through digitalisation as well as the coupling of end-use sectors, particularly transport, and heating and cooling, via greater electrification, promoting decentralisation and designing flexible power grids.

“The energy transformation is gaining momentum, but it must accelerate even faster,” concluded Mr. La Camera. “The UN’s 2030 Sustainable Development Agenda and the review of national climate pledges under the Paris Agreement are milestones for raising the level of ambition. Urgent action on the ground at all levels is vital, in particular unlocking the investments needed to further strengthen the momentum of this energy transformation. Speed and forward-looking leadership will be critical – the world in 2050 depends on the energy decisions we take today.”
