Sustainability

This archive tracks real progress on sustainability — from clean energy adoption and circular economy breakthroughs to policy wins and community-led conservation efforts. Each story focuses on what’s working, where, and why it matters for the long-term health of people and the planet.

House with solar panels, for article on solar power installations

U.S. solar power installations nearly triple in a single year

Solar power in the United States crossed a threshold in 2016, when the country added roughly 14.6 gigawatts of new capacity — nearly tripling the year before and outpacing every other energy source, including natural gas. Behind the numbers stood more than 260,000 solar workers, quietly proving that a cleaner grid was arriving faster than forecasters had dared to predict.

Florida votes overwhelmingly to remove property tax on solar equipment

Florida solar got a boost on Election Day 2016, when roughly 73% of voters approved Amendment 4, exempting home solar equipment from property tax assessments. The measure drew a rare bipartisan coalition and passed alongside the defeat of a utility-backed counter-measure. In the years that followed, Florida climbed from near the bottom of U.S. solar rankings toward the top.

Glowing engine powering a glow-in-the-dark bicycle path at night

Poland’s glow-in-the-dark bicycle path runs entirely on solar power

A glow-in-the-dark bicycle path opened in the rural Polish town of Lidzbark Warminski, emitting deep blue light for up to 10 hours a night without touching the electrical grid. Luminophore particles embedded in the 328-foot surface soak up sunlight by day and release it after dark. A small, quiet experiment in making rural roads safer — and unexpectedly beautiful.

Renewables top all other new power sources for the first time

Renewable energy quietly crossed a threshold in 2015, when solar, wind, and other renewables made up roughly two-thirds of all new power capacity added worldwide, according to an IEA report released the following year. China led the wave, installing more solar and wind than any other country. It was the moment the energy transition stopped feeling hypothetical.
