Come 2050 and the world is likely to be getting 80% of its electricity requirement fulfilled from non-fossil fuel sources. Wind energy capacity will grow 15-fold and solar PV will expand 20-fold from today as these technologies make themselves relevant with low costs and advancing technologies. Their business case will become 'overwhelming' by 2030.
"But the problem is this: even if all electricity was 'green' from this day forward, humanity would still fail to achieve net zero emissions by 2050. Not everything can be electrified," reads the foreword of DNV's Group President and CEO Remi Eriksen in the group's 5th annual edition of Energy Transition Outlook 2021 (ETO 2021). This kind of sums up the sentiment expressed in rest of the report. He adds that the world needs to have 'vastly more' green electricity, and on a 'dramatically accelerated timescale'.
According to the report's forecast, the world is headed towards global warming of 2.3º C by 2100 after the 1.5º C carbon budget is exhausted by 2030 when global energy-related emissions fall only 9% lower than 2019 emissions. The world is clearly not meeting ambitions laid down in the Paris Agreement, and the window of opportunity to close the gap is a short one.
Put this way, the DNV report seems to echo the fears expressed by the United Nations' Intergovernmental Panel on Climate Change (IPCC) as part 1 of its 6th assessment report (AR6) that point towards 1.5º C warming in the early 2030s.
Already cheapest from of new power today, solar PV and wind are likely to become even more cheaper than operating existing thermal power in most places. By 2050, solar and wind energy will account for 69% of grid connected power generation while fossil power will be only 13%.
Some of the other key takeaways from the report are as follows:
Eriksen makes an eerie conclusion, "The window to avoid catastrophic climate change is closing soon, and the costs of not doing so unimaginable."

DNV will present its scenario on how to limit global warming to 1.5º C in its forthcoming publication Pathway to net zero emissions.
