Worldwide solar and wind power generation increased faster than the growth of electricity demand in the first six months of the year, according to a new analysis. (Produced by Julián Trejo Bax) By ALEXA ST. JOHN
Wind and solar are growing faster than any other sources of electricity in history, according to new analysis from thinktank Ember. It says they are now growing fast enough to exceed rising demand, meaning there will be a peak in fossil fuel electricity generation – and emissions – from this year.
Solar technology generated 5% of U.S. electricity in 2024. 1 Electricity demand peaks at different times than PV generation, creating energy surpluses and deficits. Energy storage and demand management help match PV generation with demand. 6
In 2022, the world added more new solar capacity than all other energy sources for electricity combined. Global energy generation from solar photovoltaic (PV) panels, which convert sunlight into electricity, rose by 270 terawatt hours (TWh), marking a 26% rise on the previous year.
The short answer is yes, solar panels do work when it's cloudy, but they don't make as much power. Advanced solar technologies, like bifacial panels and systems with battery storage, can help maximize energy production even in overcast. . Absolutely, photovoltaic systems do indeed function on overcast days! While their efficiency may dip compared to sunny conditions, the solar panel still allows them to produce about 10-25% of their maximum output. Factors such as panel quality and system setup. . Even on overcast days, the atmosphere contains a significant amount of diffuse radiation, which is sufficient to maintain system generation. In Central Europe, for example, irradiance levels on cloudy days typically range from 15% to 30% of those on clear days.

Future of DALI Wireless DALI (Bluetooth Mesh, Thread, Zigbee). AI-driven lighting analytics. Digital twins for smart buildings. D4i in smart cities – luminaire-level intelligence. The DALI Lighting Control Protocol is the most reliable and flexible lighting control standard available today.
DALI (Digital Addressable Lighting Interface) Lighting Control System is a type of lighting control system that uses a digital signal to control the intensity and color of lighting fixtures.
DALI Sensors: DALI sensors detect motion, light levels, or occupancy and send signals to the DALI controller to adjust the lighting levels accordingly. They help reduce energy consumption by automatically dimming or turning off lights when unnecessary. DALI Switches: DALI switches are devices that manually control the lighting system.
With DALI-based digital lighting, any ballast or group of ballasts on the network can be given an ON/OFF or DIM command without rewiring the circuits. This enables compliance with prevailing energy code requirements for automatic shutoff in controlled spaces without the need for a control panel with a scheduling function.
