在读 How to Avoid a Climate Disaster
Here's the question: How many batteries would they need order to power Tokyo for three days, until the storm passes and they can turn the turbines back on? The answer is more than 14 million batteries. Thats more storage capacity than the world produces in a decade. Purchase Price: S400 billion. Averaged over the lifetime of the batteries, thats an annual expense of more than $27 billion. " And that's just the capital cost of the batteries; it doesn't include other expenses like installation and maintenance This example is entirely hypothetical. No one seriously thinks Tokyo should get all its electricity from wind or store all of it in todays batteries. I'm using this illustration to make a crucial point It's extremely difficult and expensive to store electricity on a large scale, but that's one of the things we'll need to do if we're going to rely on intermittent sources to provide Significant percentage of clean electricity in the coming years And we're going to need much more clean electricity in the coming years. Most experts agree that as we electrify other carbon intensive processes like making steel and running cars, the world's electricity supply will need to double or even triple by 2050. And that doesnt even account for Population growt or the fact that people will get richer and use more electricity. So the world will need much more than three times the electricity we generate now.
