| > First, it only refers to the US, while the headline makes no such qualification. Yes the title should be "Land-Based Wind Market Report: 2021 Edition Released" but it still won't say US cause it's not in the title. > Second, this refers only to electricity generation, which is roughly 25% of US energy use, or 20% if you include energy embedded in imports, mostly fueled by fossil fuels in China. Of course it's only about electricity generation? > Third, this refers only to gros capacity. For those who have been asleep, the effective energy capacity is far lower for renewables than for stable power sources due to intermittency. That's what you usually mention when you build something that generates energy. Nothing unusual here either. > inb4 By referring to facts you have shown you are clearly on the wrong team. What's with this unhealthy polarization? What teams are you talking about? |
This latter number is about 3x higher than the useful output since if you need something other than heat, say a car to move, or grid electricity then 2/3rds of the energy will be lost as heat while converting the energy to motion (and then to electricity).
And if you do need heat, then an electric heat pump will provide 2-5 times the heat if you feed it one unit of energy.
This is why electrification of everything that can be electrified will reduce total energy requirements substantially (while increasing the amount of electrical energy we need slightly).
