Most smartphone batteries retain about 80% of their capacity after 500 complete charge cycles (roughly 1.5–2 years). Xiaomi demonstrated 210W HyperCharge that can fill a 4,000 mAh battery in about 8 minutes. Qi2 was announced in 2023 and supports up to 15W wireless charging, with the iPhone 15 (late 2024) first to officially support it.…

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…

Rowan University opened the Jean & Ric Edelman Fossil Park Museum in late June 2025, a mass-timber building that runs fossil-fuel-free with geothermal heating and planned solar to achieve net-zero energy, designed by Buro Happold and Ennead Architects. Brooklyn College began drilling a 500-foot geothermal well in early June 2025 to retrofit a 20,000-square-foot building…

Deloitte forecasts global data center electricity use will nearly double from about 536 TWh in 2025 to over 1,000 TWh by 2030. S&P Global projects U.S. data center power demand rising about 12% annually through 2030, with roughly 60% of new demand potentially met by natural gas. Germany passed the Energy Efficiency Act (EnEFG) requiring…

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…
