In this, the fifth posting in a series that is focused on humanity's challenges in the 21st century and how science and technology can help, we look at energy. It seems appropriate since today is a celebration of Energy Efficiency Day (EE DAY 2021). 

Established five years ago by energy utilities, and manufacturers in the industry, EE DAY promotes the sharing of information regarding programs, technologies, and policies that focus on efficiency whether it be in production, distribution, or consumption. This year's EE DAY message is "Save Money. Cut Carbon. Breathe Easier." 

Our challenge as a species is to be able to achieve these three goals while dealing with the growing demand for energy around the globe both in the Developed and Developing worlds. Can we cut carbon and deliver more energy where it is needed? Do we have the capacity and solutions to achieve net-zero emissions globally by 2050 or sooner without negatively impacting consumers?

Do we need to produce 879 exajoules of energy in 2050 for all of humanity to have access to reliable electricity sources? How else can the power gap between now and then be addressed?

I love the way you highlight the numbers that are frankly staggering. Shows simultaneously that 1) no, EE alone of course won't solve all our energy challenges but 2) the challenge is so huge that any gaps EE can fill will be crucial
