A wide range of countries make efforts to track their entire national public energy research, development and demonstration (RD&D) activity on an ongoing basis, also sharing the collected data with the IEA through a standardised template. However, the approaches adopted to collect data vary...

This energy technology roadmap envisions that by 2050, photovoltaic could provide 11% of global electricity production (4 500 TWh per year), corresponding to 3 000 gigawatts of cumulative installed photovoltaic capacity. In addition to contributing to significant greenhouse gas emission...

The emerging technology known as concentrating solar power, or CSP, holds much promise for countries with plenty of sunshine and clear skies. For CSP to claim its share of the coming energy revolution, concerted action is required over the next ten years by scientists, industry, governments,...

The development of smart grids – which the IEA defines as an electricity network that uses digital and other advanced technologies to monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end users – is essential if the global...

Almost one quarter of global electricity could be generated from nuclear power by 2050, making a major contribution to cutting greenhouse gas emissions. This is the central finding of the Nuclear Energy Technology Roadmap, published today by the International Energy Agency (IEA) and the OECD...

Buildings account for almost a third of final energy consumption globally and are an equally important source of CO2 emissions. Currently, both space heating and cooling as well as hot water are estimated to account for roughly half of global energy consumption in buildings. Energy-efficient and...

The report shows how China, already the world’s largest wind market, could reach 1,000 GW of wind power by the middle of the century, an achievement that would reduce carbon dioxide emissions by 1.5 gigatonnes per year, or roughly equivalent to the combined CO2 emissions of Germany, France and...
