Electric motors and heat pumps are far more energy efficient than their combustion counterparts. Solar and wind electricity can be generated in situ or transported via cable. No need to power ships and trucks for fossil delivery to refineries or fuel stations. Thus we will end up with less primary energy.
How does a heat pump helps you firing Portland cement, ceramics, melting glass and metal, fixating air nitrogen? And these are all 24/7 industrial processes.
These are still big challenges, but very bright people already work on them. For example, Germany’s Hans-Joachim Schellnhuber, a top climate scientist, is working on climate-friendly buildings. Other research groups have worked on recycling concrete into more climate-friendly cement as a co-product of electrical steel processes.
The race is about new energy. An old gas plant is still cheap to operate. But when faced with the decision of building new capacity, solar is cheaper and its not close. New gas energy is grinding to a halt.
Electricity for heat pumps and moving vehicles is far more efficient than burning stuff. You need to look up the difference between energy and exergy. Electricity is 100% exergy, and can power heat pumps. Fossil fuels not.

In cement production particularly: Pumps + co 2 capture = 5x efficiency in the process + negative carbon footprint
Add renewables and voila, best cement factory in the world

Do you know a heat pump which operates at 1400-1600 deg C?
