Solar and wind-power can compete very efficiently in a free market. They actually outperform all other forms of energy-production (it is the cheapest way to produce energy). Also every year they get much cheaper. I would recommend this video: [VIDEO]

It is unfortunate that the government of Pakistan and their investors (China and the IMF) made poor investment decisions. They should feel free to go back to debt holders to renegotiate the debt, or default on it and hand the stranded assets back to creditors. The death spiral is of their own making, and will only accelerate as solar PV and battery cost declines continue. Electricity consumers will simply go off the grid. Such is the risk of unsophisticated investors not understanding the market in which they invest. Capital being at risk is an inherent component of investment. My condolences and sympathy to the people of Pakistan caught in the mess. The global energy transition will be volatile.

The group that is doing this report suggests batteries reduced by 83% in the last decade and will reduce by a further 80% in the next decade: [VIDEO] They predict similar for wind and solar, and notably they correctly predicted the price drop of solar 10 years ago till today. Which seemed a crazy thing to suggest 10 years ago.
