Over the last 5 years, the price of new wind power in the US has dropped 58% and the price of new solar power has dropped 78%. Utility-scale solar in the West and Southwest is now at times cheaper than new natural gas plants. Even after removing the federal solar Investment Tax Credit of 30%, a recent New Mexico solar deal is priced at 6 cents / kwh. By contrast, new natural gas electricity plants have costs between 6.4 to 9 cents per kwh, according to the EIA.

Tesla batteries are nowhere near "utility scale". They aren't even shipping yet. And yes, other things in the future will be cheaper and better.
