The planet is pretty much ready to go 100 percent renewable by 2050.
, renewable energy sources accounted for roughly 15 percent of total electricity generation and 10 percent of total U.S. energy consumption in 2016. Some of that investment in renewable energy is being led by places that we tend to associate with petroleum, like Texas, where wind energy provided more than 12 percent of that state’s electricity in 2016.from renewable sources. And this is more practical than environmental: A hybrid electric tank uses less gas, and doesn’t need to refuel as often.
For small nation-states, like Singapore, the task of going totally renewable would be hard—but doable. Most countries could manage by mixing energy generation into existing landscapes—putting solar panels on rooftops, for example, or placing wind turbines on ranch land—while also creating dedicated renewable energy power plants like solar farms.the amount of land dedicated to energy production overall.
“With oil and gas, you have to keep drilling and mining, and pollution keeps going on forever,” says Jacobson. “Worldwide, we have more than 4 million air pollution deaths from it. Things have to change—they’re not sustainable as they are.” “When you’re driving a car, only 17 to 20 percent of the energy in the gasoline goes to move the car. The rest is waste heat,” says Jacobson. “Whereas in an electric car, 80 to 86 percent of the electricity goes to move a car. You need one-fourth to one-fifth of the energy to drive an electric car than to drive a gasoline car.”
