Renewable Energy Policies for Cities: Buildings is one of a series of three briefs intended to help policy makers accelerate efforts to create sustainable cities powered by renewable energy.

This brief focuses on technologies for the sustainable production of liquid biofuels.

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.

Pacific islands are endowed with a rich variety of renewable energy resources, providing a viable and attractive alternative to fossil-fuel imports. IRENA’s multi-faceted work across the region is reflected in Pacific Lighthouses: Renewable Energy Roadmapping for Islands. The main report, intended to provide a framework for further action, is accompanied by 15 reports on specific islands, as well as a report detailing hybrid power systems for the Pacific.

The Global Atlas for Solar and Wind Energy project aims to create a collaborative internetbased Geographic Information System (GIS) for wind and solar resources that can direct and enhance cooperation on global scenarios and strategies and support decision-making, especially in areas where existing information is insufficient.

A Path to Prosperity: Renewable energy for islands was developed in support of the Renewable Energy Forum, a one-day forum preceding the Third International Conference on Small Island Developing States (SIDS), held in Apia, Samoa, on 1-4 September 2014. The booklet is a collection of case studies submitted by SIDS and development partners to complement Forum discussions.

The brief, released at the global climate meeting COP25, underlines the opportunity to address the climate threat, decarbonise energy use and simultaneously achieve multiple Sustainable Development Goals.

The Global Renewable Energy Atlas, which went live in January 2013 with components for solar and wind energy, is an open-access on-line resource intended to support well-informed energy policy and investment decisions.

Tourism is an important economic driver for island economies. Energy supply, vital for the tourism industry, is still dominated by oil products which increases islands’ vulnerability to the environmental impact of fossil-fuel use, as well as to oil price volatility, which makes it difficult for the industry to remain competitive

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

Panama has vast potential to develop renewables. The National Energy Plan suggests that as much as 70% of the country's energy supply could be renewable by 2050.

The East African Rift region holds significant geothermal potential. This report offers recommendations to fast-track regional geothermal energy development.

This publication aims to increase awareness, share experiences and lessons, and provide recommendations for expanding geothermal heat use in the agri-food sector. The analysis in this document suggests the following six broad critical factors.

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 brief examines ocean thermal energy conversion (OTEC) technologies, one of the key methods for tapping renewable energy from the world’s oceans.

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.

This brief takes stock of the opportunity at hand – detailing the dynamism and the innovations in the off-grid renewable energy sector. Building on IRENA’s growing body of work on the topic, it highlights the latest trends and advances, including innovations in delivery and financing models.   

IRENA's 10th Assembly booklet charts global advances over the past decade and calls for a new Decade of Action on renewables. Comparative graphs and data illuminate the road ahead.

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。

This working paper is part of a set of five reports on hydropower, wind, biomass, concentrating solar power and solar pholtovoltaics that address the current costs of these key renewable power technology options.

Islands around the world rely on costly fossil-fuel imports, often from distant locations, which can burden government budgets and inhibit investment in social and economic development.

The size of wind turbines has continuously increased over several decades to boost power generation from this key renewable energy source. As this technology brief from IRENA and IEA-ETSAP notes, large-scale wind farms and larger turbines drive the ongoing reduction of electricity costs.

This report from IRENA examines the evolution of solar PV simulators, from single-rooftop assessments at the household level to large-scale, aggregate-level analyses undertaken by municipal authorities and other large entities.

With many economies facing slow growth prospects, policy makers increasingly see chances for greater income, improved trade balances, industrial development and job creation through renewable energy deployment. However, detailed evidence on these effects remains limited.

The potential of oceans as an energy source is staggering – more than sufficient to meet global electricity demand well into the future. Ocean resources vary from tidal currents and waves, to temperature and salinity gradients.
