How solar energy got so cheap, and why it's not everywhere (yet)
A lot speaks for solar energy. It's clean, renewable – and now even cheaper than energy from fossil fuels like coal or natural gas. Sounds pretty great, right? But ...

A strong X1.9 solar flare erupted from the sun's surface at 9:49 p.m. ET on Nov. 30, and NASA’s Solar Dynamics Observatory caught it in action. The flare appears as a bright flash on the Sun’s edge, followed by a plume of hot material rising into space. Solar flares are powerful bursts of energy. They can disturb radio communications, affect navigation signals, and pose risks to spacecraft and astronauts — which is why NASA and NOAA track them so closely. Credit: NASA/SDO | NASA 360

The Sun emitted a strong solar flare on Nov. 30, 2025, peaking at 9:49 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9 class: go.nasa.gov/4alXf6P Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such sp
