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...

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...

Biofuels could provide up to 27% of total transport fuel worldwide by 2050. The use of transport fuels from biomass, when produced sustainably, can help cut petroleum use and reduce CO2 emissions in the transport sector, especially in heavy transport. Sustainable biofuel technologies, in...

The technology roadmap for Geothermal Heat and Power offers a strategic plan to maximise deployment of these energy resources by 2050. It projects that 1 400 TWh of electricity per year could come from geothermal power by 2050, up from 67 TWh at present. Additionally, geothermal heat (not...

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,...
