Expanding markets for clean and efficient technologies will increase energy security and help reduce greenhouse gas emissions. But many promising technologies are still too expensive or face other obstacles to commercial deployment. Governments need to consider deployment policies to create...

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...

Wind energy is perhaps the most advanced of the “new” renewable energy technologies, but there is still much work to be done. This energy technology roadmap identifies the key tasks that must be undertaken in order to achieve a vision of over 2 000 GW of wind energy capacity by 2050....
