There are a number of misunderstandings when it comes to wind and solar I wish more people were aware of.

Wind and solar is only electricity. Electricity is 15-20 percent of our energy needs.

Wind and solar needs backup sources from either gas, coal, nuclear or oil because of the intermittency issue and low capacity factor.

Regardless of whether solar cells become cheaper, it makes energy more expensive as a whole because it makes the energy system more complex and as many might have learned in physics, starting up something take more energy than when it's up and running. This is true for coal plants too and with wind and solar being highly fluctuating and with highly fluctuating demands on the backup sources.

The use of fossil fuel is increasing not decreasing more than wind and solar.

You can't make either windmills or solar cells without fossil fuel.

Wind and solar is only 1% of the worlds energy not projected to be much more than 3-4% in 2040.

In other words, fossil fuels aren't going anywhere anytime soon.
