The first rooftop solar panels were installed in 1883

In 1883, New York inventor Charles Fritts created the first solar cell by coating selenium with a thin layer of gold. The cell achieved energy conversion rates of 1 to 2% compared to the 15 to 20% of modern photovoltaics.

Light energy can be transformed into electricity in solar cells via the photovoltaic effect

When light strikes semiconducting material, it can knock electrons out of atoms, creating a charge imbalance within the material. A wire connecting the oppositely charged regions can allow electrons to flow back, balancing the charges and producing an electric current that can be harnessed to power devices.

Using a drone, Chinese photographer Weimin Chu captured the deployment of solar and wind power installations across the country, which accounted for half of all global installations in 2025. The images show modern infrastructure juxtaposed with natural landscapes and was featured in an award-winning exhibition presented by Greenpeace in 2025.

Wind turbines are limited to capturing no more than 59.3% of incoming wind energy

In 1919, German physicist Albert Betz applied the laws of conservation of mass and momentum to airstreams to calculate the theoretical limit. However, real-world turbines only convert 35 to 45% of available wind energy into electricity.

Many of the images are captured at different nonvisible wavelengths, such as UV, and then colorized into the visible range to illuminate the sun's magnetic field and magnetism-driven solar activity, including coronal loops and filamentary prominences. Close-up imaging also reveals solar granules—Texas-sized cells of material that bubble to the surface from the convection zone.

Solar panels can create pollinator-friendly habitats by protecting flowering plants

An example of agrivoltaics, where land is used for solar energy production and agriculture, the panels provide clean energy while also shading plants from excessive sunlight. Pollinator-friendly plants can improve water quality and reduce soil erosion by obstructing the wind.

As of 2025, most EV batteries retain 95% or more of their range after three years

Data from over 30,000 electric vehicles shows that their batteries are lasting much longer than initially projected, which researchers suggest is due to improved battery management systems and real-world use often being less rigorous than high-performance testing. Cars with 150,000 miles or more that have not had a battery replacement retain at least 83% of their original range.

Artificial photosynthesis turns CO₂ into sustainable fuel

Carbon conversion focuses on a central perplexing question: if carbon dioxide is a leading driver of climate change, and fossil fuels are made of carbon-based molecules, can we devise a way to convert CO₂ into useful alternatives efficiently? This video breaks down a potential pathway using artificial photosynthesis, which uses sunlight to convert CO₂ into fuel.

The Kardashev scale measures a civilization's advancement based on energy use
