Power generation solar energy price trend chart

What percentage of US electricity is generated by solar?

U.S. PV Deployment In 2023, PV represented approximately 54% of new U.S. electric generation capacity, compared to 6% in 2010. Solar still represented only 11.2% of net summer capacity and 5.6% of annual generation in 2023. However, 22 states generated more than 5% of their electricity from solar, with California leading the way at 28.2%.

How does technology affect the cost of solar power?

This states that the cost of technology falls consistently as the cumulative production of that technology increases. The chart shows the perfect example of this for solar power. This data comes from the International Renewable Agency, Greg Nemet, and Doyne Farmer & François Lafond.

How has solar power changed over time?

Both are measured on logarithmic scales, and the trend follows a straight line. That means the fall in cost has been exponential. Costs have fallen by around 20% every time the global cumulative capacity doubles. Over four decades, solar power has transformed from one of the most expensive electricity sources to the cheapest in many countries.

What are the economic benefits of solar & wind?

The economic benefits of solar and wind technologies – in addition to their environmental benefits – are now compelling. Owing to soaring fossil fuel prices, the 2021-2022 period saw one of the largest improvements in the competitiveness of renewable power in the last two decades.
