In 2023, China, Europe, and the US each achieved record solar installations, with China leading at 180-230 gigawatts, and Europe growing by 40% from the previous year to 58 gigawatts. Solar energy, now the most affordable electricity source in many countries, saw a significant price drop in Europe, making solar panels more accessible than ever....Continue Reading

  James Hansen, professor of Earth and Environmental Sciences at Columbia University, former NASA scientist, and the planet’s preeminent climatologist, was among the first to sound the alarm on climate change during his 1988 testimony before Congress. Since then, he has continued to shine a light on the problem through lectures, interviews, TED talks, and his...Continue Reading

This gure shows greenhouse gas emissions (positive values) and sinks (negative values), by source, in the United States from 1990 to 2014. For consistency, emissions are expressed in million metric tons of carbon dioxide equivalents. All electric power emissions are grouped together in the “Electricity generation” sector, so other sectors such as “Residential” and “Commercial”...Continue Reading

Increasing renewable energy consumption. Consumption of renewable fuels that do not produce carbon dioxide increased 9% during the first six months of 2016 compared with the same period in 2015. Wind energy, which saw the largest electricity generating capacity additions of any fuel in 2015, accounted for nearly half the increase. Hydroelectric power, which has...Continue Reading

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2014, CO2 accounted for about 80.9% of all U.S. greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth’s carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals)....Continue Reading

US solar energy industry added more jobs in 2015 than the US oil & gas extraction & pipeline industries added combined, and grew 12x faster than the US economy as a whole.Continue Reading
