The cosmological constant is the energy density of empty space. It's positive.
Space is expanding, distant galaxies are all redshifted etc. There's now more empty space than there was before.
More empty space than before means more energy than before with positive cosmological constant.
To make matters worse the expansion is accelerating. The universe's increase in energy is increasing at an increasing rate.

The universe is creating energy from nothing.
How is this allowed?

Could you seal a cubic meter of vacuum in a strong steel box to keep it at a constant size and siphon off the expansion energy to power a small city?
