The transition toward zero-carbon energy is crossing an irreversible economic tipping point. Solar and wind are now cheaper per megawatt-hour than new coal or fossil gas across more than 90 percent of the world’s power markets.
Next-Generation Perovskite Cells
By pairing conventional silicon wafers with ultra-thin perovskite crystal coatings, laboratory solar efficiencies have surged past 33 percent, promising to cut the cost of rooftop and utility-scale installations in half over the next five years.
