When it comes to energy scarcity, I find that highly unlikely. Even if battery technology doesn't improve, or neither do distribution networks.

Perhaps the biggest offender here is the car. But considering how well electric bikes and other lightweight devices work (with one electric car, you can power more than 300 e-bikes), we've got energy to spare for getting around. Plus, we avoid wasting large swaths of surface area on oversized vehicles that are overkill for their actual use. And hey, by taking cars off the road, we also get cleaner air (those tires pollute too), less noise, fewer accidents, and fewer obstacles for more efficient, alternative forms of transport. (I mean, sitting in traffic for 30+ minutes a day isn't exactly efficient, right?) But I won't drone on about that...

What I really wanted to highlight is how incredibly cheap solar panels are becoming. Worried there's not enough sunlight in the winter? Just go big! And the excess energy in the summer can surely be used for air conditioning, powering cloud servers, and for other uses we can't even imagine yet.

As for the battery to store what's produced in a day, it's really not a big deal. They can even be larger than the lithium ones we have now.

So, the real question is, once we ditch fossil fuels, what are we going to do with all this excess energy?
