Solar and wind just passed another big turning point, Cheaper n Better

Solar and wind just passed another big turning point:

So solar and wind power generation is reaching a threshold where renewable energy is cheaper than fossil fuel-based power in Germany and UK. That is before counting the subsidies for renewables, and ignoring the massive externality costs of our historically favorite dirty black fuel.

Note the discussion of the virtuous cycle of renewable fuels. As base load power moves up from 5% renewables the costs of traditional power plants becomes more expensive, essentially they become more peak-power generators and less base-load power.

Solar has the added advantage of offing more distributed power generation, usually at the point of use. So solar starts to really cut down on the massive loss of power over distribution channels.

In the US, really cheap NatGas is a no-brainer decision for converting coal plants. It is so much cleaner in all respects. But new fossil fuel power plants will be harder and harder to justify to shareholders and to the PSC.

In the meanwhile, nuclear sits on the sidelines, leaving fission and fusion as a non option in the foreseeable future.

If momentum builds for homeowners and businesses to move to at-source power generation (say Solar City), the building momentum could be a real game-changer.
