Current trends in energy supply and use are unsustainable – economically, environmentally and socially. Without decisive action, energy-related greenhouse-gas (GHG) emissions would lead to considerable climate degradation with an average 6°C global warming. We can and must change the path we...

The solar heating and cooling (SHC) roadmap outlines a pathway for solar energy to supply almost one sixth (18 EJ) of the world’s total energy use for both heating and cooling by 2050. This would save some 800 megatonnes of carbon dioxide (CO2) emissions per year; more than the total CO2...

Producing electricity from renewable energy sources has undeniable appeal, both for environmental reasons and for reducing our dependence on fossil fuels. This book assesses the outlook for six leading renewable energy technologies: small hydro power, solar photovoltaic, concentrating solar...

A review of the experience of IEA countries after the oil crises in the 1970s, which initiated a surge of investments in renewables research and development. While use of renewables has grown rapidly, they still account for only a small portion of the IEA energy mix. This work examines policies...

In 90 minutes, enough sunlight strikes the earth to provide the entire planet's energy needs for one year. While solar energy is abundant, it represents a tiny fraction of the world’s current energy mix. But this is changing rapidly and is being driven by global action to improve energy access...

Renewable energy has received high levels of attention in recent years as an alternative to traditional hydrocarbons.  Governments, industry and consumers have adopted and promoted renewable technologies in response to concerns about energy security and the environment, and as a solution to...

Ce document donne un aperçu du développement des énergies renouvelables dans les régions ultrapériphériques de l’Union européenne (RUP de l’UE), se concentrant sur la capacité de ces énergies à contribuer à la transition verte tout en ouvrant des perspectives de développement...

This paper provides a snapshot of the development of renewable energies in the European Union Outermost Regions (EU ORs), focusing on their potential to contribute to the green transition while creating sustainable economic development opportunities. It reviews the policy frameworks and tools in...

Total fixed investment, also called gross fixed capital formation (GFCF), in real terms. It is defined as the outlays (purchases and own-account production) of industries, producers of government services and producers of private non-profit services to households, on additions of new durable...
