    because it's kinetic energy.

    Because we can directly measure the solar wind, we know what it is, it is not 'dark'.

    We use the term 'dark energy' for something we can not measure and we don't know what it really is.

    We see that all galaxies outside our local cluster of galaxies are moving away from us. We also see that they are speeding up. We can not see any reason for that speedup. That is why we call it 'dark energy'.

    Because Larry David does a good impression of Jean-Luc Picard?
