This set of briefs, prepared by the International Renewable Energy Agency (IRENA), highlights challenges and opportunities as the world seeks climate-safe energy solutions.

This report provides a comprehensive pathway for the development of a sustainable and cleaner regional energy system.

With solar and wind installation breaking new records each year, countries with ambitious plans for these renewable power-generation technologies must consider the best ways to integrate variable renewables onto the grid. Electricity storage is a key option available to manage variability and ensure reliable, round-the-clock supply. Declining costs and improving capacities have made batteries and other storage technologies increasingly practical for upgrading existing power systems.

This report details a comprehensive pathway for the development of a sustainable and cleaner regional energy system for ASEAN.

This working paper draws on engagement with a Transport Action Team of experts and expands on the transport-related findings published in IRENA’s report REmap: Roadmap for a Renewable Energy Future, 2016 Edition.

Renewable energy needs to be scaled up at least six times faster for the world to start meeting key decarbonisation and climate mitigation goals. Yet the envisaged energy transformation cannot happen by itself. This report identifies focus areas where policy and decision makers need to act.

This report explores technological options in the Greater Metropolitan Area of the Central Valley of Costa Rica to contribute towards achieving the national decarbonisation goal and also improving the sustainability of their jurisdiction.

The Roadmap charts a path for the Government of Antigua and Barbuda, providing options for achieving a 100% renewable energy share in both the power and transport sectors.

This study presents options to fully unlock the world’s vast solar PV potential over the period until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

While the shift to cleaner energy systems is evident across the Group of 20 (G20), it has specific features in each country. In every case, renewable energy plays a significant role.

This study presents options to speed up the deployment of wind power, both onshore and offshore, until 2050. It builds on IRENA’s global roadmap to scale up renewables and meet climate goals.

To ensure a sustainable energy future, use of renewable energy sources and technologies needs to be scaled up not only for electricity generation but also in the end-use sectors of buildings, transport and industry.

This report explores potential for urban communities to scale-up renewables by 2030, based on estimated energy use 3,649 cities around the world. By highlighting the best practices, it examines the policies and technologies by which cities can bring about a renewable energy future.

This working paper considers how renewables and energy efficiency can work together to contribute to global energy decarbonisation by 2050. It also looks and how this synergy affects energy system and technology cost, and the effect it has on air pollution and avoidance of adverse health effects caused by these pollutants.

This outlook highlights climate-safe investment options until 2050, policies for transition and specific regional challenges. It also explores options to eventually cut emissions to zero.

Japan, holding the G20 presidency in 2019, asked the International Renewable Energy Agency (IRENA) for a report on the implications of the global energy transformation for climate and sustainability in a broad sense.

Sustainable bioenergy could even out solar and wind variability and replace fossil fuels for industry, transport and buildings.

This report outlines a pathway for the world to achieve the Paris Agreement goals and halt the pace of climate change by transforming the global energy landscape.

This study examines the policy, regulatory, financial and capacity-related challenges that the country has to address to meet targets for renewables to make up 42% of the country’s electricity mix by 2035.

本レポートでは2050 年までの気候変動に配慮した投資、エネルギー移行に必要な政策の枠組み、及び各地域が直面する課題に焦点を当てている。また、最終的に排出量をゼロにするための選択肢も探っています。

Assets like power plants can become “stranded” by unanticipated or premature write-downs, devaluation or conversion to liabilities. This will happen to some degree in the transition to a low-carbon economy. However delaying action to address climate change would result in significantly more severe asset stranding, according to this analysis by the International Renewable Energy Agency (IRENA). This raises concerns for investors and companies, as well as policy makers and regulators.
