Berlin-based climate research institute Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study indicating that, in the last decade, the cost of solar power has dropped by 87 percent, and the cost of battery storage by 85 percent.
Solar power and storage prices have dropped almost 90%::undefined
I hate to be pedantic, but the things in the picture are windmills... you know giant whirly things that are powered by wind... kind of very different from things that lie around and absorb sunlight.
You want pedantic? Those are wind turbines, champ. Windmills are used to mill grain, no matter how many people like yourself try to bastardize the term to apply to anything that rotates with air.
What's next for you people, pinwheels are now windmills?
But, but... what if we put solar panels on the windmills? ;-)
Actually I double checked and solar-assisted windmills are a thing though not likely what's shown in the picture. Actually now I'm wondering if you could also use solar to concentrate a local heat differential and power a wind turbine (though liquid is probably more efficient)
