Solar PV costs have fallen about 90% over the last decade. Modern home solar panels often exceed 20% efficiency, with typical residential systems of 5–10 kW. In the United States, over 4 million homes had solar panels by early 2024. Global rooftop PV adoption could reach about 100 million households by 2030. In the United…

Thermoradiative energy generation, nicknamed night-time solar, produces electricity by emitting infrared radiation to the cold night sky when the device is warmer than its surroundings. Unlike conventional solar cells that absorb sunlight, thermoradiative devices emit photons to space, effectively running as a solar cell in reverse and using the Earth–space temperature difference at night. In…

Perovskite-silicon tandem solar cells achieved about 29% efficiency on commercial-size cells, exceeding traditional silicon panels. Bifacial solar panels boost energy yields by up to 30% in reflective environments such as snow or sand. Floating solar farms can raise output by roughly 15% due to water cooling of the panels. Covering 10% of the world’s reservoirs…

In 2024, global clean energy investment was projected to reach $2 trillion, nearly twice the amount spent on fossil fuels. Renewable power, grid upgrades, and storage now attract more capital than oil, gas, and coal combined. Renewable energy jobs jumped to 16.2 million in 2023, up 18% from 2022. Solar PV module prices have fallen…

Global energy investment is projected to reach $3.3 trillion in 2025, with about $2.2 trillion directed to clean energy technologies. Solar is expected to attract $450 billion in 2025, making it the single biggest area of energy investment. China added 198 GW of solar and 46 GW of wind between January and May 2025, with…

Solid-state batteries use a solid electrolyte and lithium-metal anodes, offering 50–100% higher energy density than today’s Li‑ion and 1,000+ cycles with about 95% capacity retention, with Toyota targeting 750 miles per charge and 10-minute charging by 2027–2028. Lithium-sulfur batteries have a theoretical energy density above 500 Wh/kg, and a recent all-solid-state Li‑S cell demonstrated around…
