The International Energy Agency’s net zero emissions (NZE) roadmap by 2050 sets out the massive investment required to cut emissions and achieve the Paris goal of restricting global surface temperature increase to below 1.5 degree Celsius.
Under the NZE roadmap, the use of unabated fossil fuels declines sharply to just over a fifth of the total energy supply. More than two-thirds of the energy supply in 2050 will come from renewables and around a tenth from nuclear.
To meet these targets, total annual energy investment will have to surge to $5 trillion by 2030, more than tripling from just over $500 billion annually over the last five years to more than $1,600 billion in 2030. Further, the NZE roadmap requires annual investment in transmission and distribution grids to expand from $260 billion in 2021 to $820 billion in 2030.
Also, the number of public charging points for electric vehicles (EVs) will have to rise from around 1 million to 40 million during the same period, requiring annual investment of almost $90 billion by 2030.
