What happened to them

We must do the same with the climate crisis. “Less” is not the strategy you need. It’s “more, but different”. This means we must reorganize our economy and invest in new technologies, recognizing that there is no one-size-fits-all solution. Science and entrepreneurship are a patchwork: takes two steps forward, takes one step back, and two steps sideways then move forward again. In addition, human creativity stimulates economic activity. Even today, electric vehicles indirectly emit a significant amount of carbon dioxide. But in another decade, electric cars will be near-zero emissions, and we will be flying with zero carbon. Innovation and competition are the flywheels that drive knowledge and innovation. Wind turbines of the 1980s and 1990s, with steel blades 17 meters (56 feet) in diameter, produced an average of 75 kilowatt-hours of power (see diagram). Today’s turbines have carbon rotor blades with an average diameter of 126 meters, more significant than the Airbus A380, and produce an average of 7,500 kWh. This corresponds to a 100-fold increase in production capacity in just 20 years.
