Does he have a good answer for the problem of overgeneration during the summer months, and undergeneration in winter? If you run the numbers on battery energy density, cost, and what it takes to run an efficient heat pump, it seems clear that renewables alone aren’t quite a solution yet. I’d love to be wrong, though.
- alfor 4y agoI don’t know for Musk, for Seba the solution now is overgeneration: it’s more cost effective to have excess solar than to have enough batteries. The advantage is that you have period were you have free energy if a business find a way to use it. He think that as that become common more more business will find ways to take advantage of it: H2 generation, heat storage, steel/ciment, and other things we are yet to find. I came to the same conclusion when I installed solar on my motorhome, it’s was way more effective to install "too much" solar so that I have enough for the night of a gray and cold winter day. Otherwise I would had to pay 10X more in lithium batteries. In a summer sunny day I use a fraction of the power. hopefully with a large grid and many free agent and an efficient market the free energy will find uses.
