1、Technology 2020 Perspectives Energy Technology 2020 Perspectives Energy The IEA examines the full spectrum of energy issues including oil, gas and coal supply and demand, renewable energy technologies, electricity markets, energy efficiency, access to energy, demand side management and much more. Th

2、rough its work, the IEA advocates policies that will enhance the reliability, affordability and sustainability of energy in its 30 member countries, 8 association countries and beyond.

Reaching net-zero emissions in 2050 would require a much more rapid deployment of low-carbon power

4、generation. In the Faster Innovation Case, electricity generation would be about 2.5 times higher in 2050 than it is today, requiring a rate of growth equivalent to adding the entire US power sector every three years. Annual additions of renewable electricity capacity, meanwhile, would need to avera

On top of the surging demand for electricity from across different parts of the economy, a large amount of additional generation is needed fo

In order to produce the low- carbon hydrogen required to reach net-zero emissions, these electrolysers would
