IRENA report charts pathways to further accelerate energy transformation
Berlin, Germany, 14 April 2019 – 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, launched earlier in the month at the Berlin Energy Transition Dialogue, pathways to meet 86% 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 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% of the energy-related emission reduction needed.”
According to the report, 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 report said. The global economy would grow by 2.5 per cent in 2050. However, climate damages can lead to significant socioeconomic losses, the report added.
“The shift towards renewables makes economic sense,” La Camera said. “By mid-century, the global economy would be larger, and jobs created in the energy sector would boost global employment by 0.2 per cent. Policies to promote a just, fair and inclusive transition could maximise the benefits for different countries, regions and communities. This would also accelerate the achievement of affordable and universal energy access. The global energy transformation goes beyond a transformation of the energy sector. It is a transformation of our economies and societies.”
But action is lagging, the report said. While energy-related CO2 emissions continued to grow by over one per cent annually on average in the last five years, emissions would need to decline by 70% 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 heating and cooling and transport, via greater electrification, promoting decentralisation and designing flexible power grids.
“The energy transformation is gaining momentum, but it must accelerate even faster,” La Camera said. “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.”
Sustainable cooling vital for smart cities, says MIT professor
Dubai, UAE, 24 March 2019: Although cities occupy only two per cent of the world’s surface, they host up to 50% of the world’s population and are responsible for 75% of global energy consumption and 80% of CO2 emissions, said Carlo Ratti, Professor, Massachusetts Institute of Technology (MIT), and Founding Partner, Carlo Ratti Associati, during his keynote address for the ‘Design and the City of the Future’ event on March 19, at the American University in Dubai (AUD). During a comprehensive discussion on how IoT is shaping the built-environment, Ratti underscored the important role that sustainable cooling must play in cities of the future. “Fixing energy usage and occupancy is vital,” he said, “when you think about how much energy you spend cooling your homes.”
Ratti said trends in modern architecture are steadily placing greater emphasis on the importance of designing better ways to control temperature with minimum use of energy. This, he said, is especially the case in office spaces, which continue to evolve based on digital connectivity and individual requirements. Providing an example, Ratti pointed to the redesign of the Agnelli Foundation headquarters, in Turin, Italy, where Carlo Ratti Associati developed a customised environmental bubble that provides personalised heating, cooling and lighting systems to occupants throughout the building. By leveraging IoT technologies, Ratti said the building was able to optimise space and energy usage. While the company was deeply involved in the overall architecture of the historic structure, Ratti said the implementation of key technologies related to heating and cooling was done by Siemens Italy, which equipped the building with sensors for different data sets, including the location of the building’s occupants, temperature, CO2 concentration and the availability of meeting rooms.
Ratti said that he believes such an approach is scalable for other projects. “I really see it happening in high-end buildings,” he said. “Monitoring occupancy in a very fine way to create a climate around ourselves.” This, he said, is a best way to harness energy otherwise wasted from cooling in an inefficient manner.
