From the news to late-night shows, much of the media makes it sound as if renewables are on the verge of taking over. But that’s far from reality. In 2019, the latest complete year of data, 81% of the world’s energy supply came from fossil fuels, according to the International Energy Agency. Even if all nations were to fulfill their current climate promises, the IEA estimates that fossil-fuel use would still make up 73% by 2040.
And most electricity isn’t green—almost two-thirds is still generated by fossil fuels, with nuclear and hydro supplying another quarter. The solar and wind favored by environmentalists generate only 8%. Though renewables are often touted as the cheapest energy source, it’s only true when the sun is shining and the wind is blowing. If it’s a still night you need backup power, typically from fossil fuels—which makes electricity costlier because you need to pay for both the solar panel and the gas turbine. The European Union, which gets 17% of its electricity from solar and wind—the highest percentage in the world—also has some of the highest consumer electricity costs.
California uses more electricity on its pools and hot tubs than all 44 million inhabitants of Uganda consume in total.
I thinks this is another great illustration of the insanity.But to fulfill the Paris climate accords completely, the United Nations says that global emissions would have to plunge even further every year for the rest of the decade. In 2021 emissions would have to drop by more than double the lockdown-induced decline. By the end of 2030, they’d have to have fallen by 11 times what they did in 2020. Not exactly realistic.
If they spun at high speed all the time, they would be a great and inexpensive power source. Problem is that there is a whole lot of time they are not spinning at all. Even someone like me that can still run a 4.4 40' would be able to get through the gauntlet.Maybe fencing along the southern border. Orrrrr..... place windmills near the ground, spinning at high speeds, very close together from Texas to the Pacific. That would make running the gauntlet like something from Hunger Games.
So....we should hook them up to coal powered energy sources?If they spun at high speed all the time, they would be a great and inexpensive power source. Problem is that there is a whole lot of time they are not spinning at all. Even someone like me that can still run a 4.4 40' would be able to get through the gauntlet.
