Arizona was just one example, but solar is about the same price across the whole American Southwest including Nevada, Texas, Colorado, New Mexico and California. Good news is that wind is
also getting this cheap in the Southwest.

Solar has a faster rate of cost decline than wind and as most of the cost structure gradually withers away to nothing, the primary remaining costs will be for land and electricity transmission to the load. When land is the main cost, what matters is the price per acre and the amount of insolation per acre. Southern Arizona, with its
dirt cheap land and intense year-round sunshine, will probably in the future have the lowest cost energy generation in the USA. Then, to eliminate transmission costs, southern Arizona may develop into a hotspot for energy-intensive industries like steel and aluminum smelting and metal recycling.
As the map shows, for solar Arizona as a whole has the best long term potential because it’s the sunniest state in the USA and has a lot of cheap land that actually could benefit ecologically from the shade and water concentration a solar farm provides. Parts of southeastern California, southern New Mexico, and western Texas are also strong candidates, and land in these regions is dirt cheap as well.

ranching may also be done to earn extra income and keep the plant growth trimmed.
Solar panels depend on energy from the sun. Energy from the sun creates heat. But do solar panels heat up their surroundings? Read more on solars effects here.

- They provide shade to areas normally exposed to intense sunlight.
- This cools vegetation during the day while warming it at night as panels help retain the heat lost to contact with the cool night air.
- While a solar system can change the light dynamics of an area, crops grow at approximately the same rate with or without solar panels.
- In many cases, a panel system can provide opportunities to grow shade-tolerant or shade-dependent crops that might otherwise struggle to develop.
- Some ranchers even like to graze sheep and cattle around panels as a simple way to maintain overgrown vegetation.
- Protect your soil by blocking the wind and limiting erosion
- Preserve soil nutrients and water
- Provide habitat and food for bees and butterfly pollinators
- Save your irrigation water from evaporation

$20/MWh is currently the low end of solar & wind Power Purchase Agreements in the American Southwest for the last couple years. The average is about $25-30/MWh even with many bids now including storage as part of the package. I think that’s probably about equivalent to the $10-15/MWh projects in the Middle East after accounting for the differential in wages for labor and vehicle fuel costs. Prices have risen since 2020 though because of the supply crunch and logistics hell.
Mexico has even more potential for cheap solar, but in cursory research it looks to me like the Mexican federal government has put up major regulatory hurdles to installing solar and wind. Mexico had bids around $20/MWh on average 5 years ago. Someday I think the dam will break and Mexico will tap the immense solar resource in their deserts to build up their economy and help make AC much more affordable for the 84% of Mexican households that don't currently have AC to help them get through the brutal summer heat that gets worse every year. Canadians will pay more for power than Americans and Mexicans, but it'll still be a lot cheaper than power today that mostly comes from hydroelectric plants.

For bookmarking I’d recommend checking out the annual reports from Lazard, the Energy Information Administration (EIA), the National Renewable Energy Laboratory (NREL), and the Lawrence Berkeley Laboratory.
Prices for power purchase agreements have been rising steadily since the end of last year. According to solar developers, interconnection delays, permitting challenges, and supply chain constraints are likely to keep them high.

According to the auction’s preliminary results, solar may account for 55% of contracted power with 3.0 TWh. Final results will be announced on November 22.
