Let me start with a rather monumental report published by the International Energy Agency: Net Zero by 2050 A Roadmap for the Global Energy Sector There are 400 milestones to get there from here.   For success, the world will need to fully commit.  Hasn't happened yet.

The United Arab Emirates is attempting to gain the travel interest of the world by building the biggest of almost everything.  They figure that people would want to visit a country with these attractions.  It seems to be working. Dubai in particular began with pearls, shifted to oil, and quickly ran out of this resource, so turned to finances and tourism, t hrough having : Ain Dubai, the world's largest Ferris Wheel, which opened last year.  From ground to top, 820 feet.  Each of i
