Responding to a Gleneagles G8 Summit request, this book shows how changes in energy efficiency, economic structure, income, prices and fuel mix have affected recent trends in energy use and CO2 emissions in IEA countries. The results are a “wake-up call” for us all. Since 1990, the rate of...

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...

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...

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...

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...
