The silicon solar cell was invented in 1954. In the 1970s and 1980s, solar panels first started appearing on roofs. But even by the turn of the century, the total global capacity was below 5 GW. Over the next decade, European and Japanese programs drove early adoption and by 2010, the global total was about 40 GW. The next decade saw dramatic reductions in the cost of solar modules and a period of rapid growth ensued.

Enhanced or next-generation geothermal energy has massive potential in the western United States. This energy source could provide hundreds of gigawatts of clean energy around the clock. Currently, there are only 4 gigawatts of geothermal energy being used nationwide.

Global sea-level rise is one of the greatest challenges of climate change. And for the more than half a billion people living in low-lying coastal areas, this threat is even greater.

People skeptical about the environmental benefits of driving an electric car often argue that the emissions associated with building the car cancel out the emissions reduction in driving it. They then argue that the greenest car is the one already sitting in your driveway. The claim is that it is better for the planet to keep one’s gas car running as long as possible.

Starting at the end of May through mid-August, Europe has suffered through five rounds of dangerously high temperatures, breaking records in 18 countries. Temperatures were the highest ever recorded for May. Western Europe was the most affected area, with reports of record-breaking temperatures in France, Ireland and the United Kingdom.

New York Governor Kathy Hochul recently announced that $35 million has been made available for public sector entities to install and operate Level 2 electric vehicle chargers in the state. The funding will reduce the purchase and installation costs of chargers thereby expanding consumer access to charging at public sites and reducing air pollution in communities across New York.

Cultivating flowering plants for gardens, farms, and landscapes commonly involves the use of herbicides to control weeds. Honeybees are drawn to these flowering areas and play an important role in their success. So what happens when bees encounter weedkillers?

Solar panels produced 51% of California’s electricity during the month of May. This was the first time the clean energy source produced more than half the state’s power for an entire month. But it wasn’t just a milestone for California; it was a milestone for the whole world. California was the first major economy to cross the 50% threshold for an entire month. In June 2025, Hungary produced 47% of its power with solar, but Hungary’s GDP is far smaller than that of California.

El Niño is a natural climate pattern during which sea surface temperatures in the central and eastern tropical Pacific Ocean become significantly warmer than average. This drives hotter weather around the world. Since the world is already warming, El Niño only amplifies that warming. The El Niño of 2023 and 2024 resulted in the hottest years ever recorded. The strong El Niño currently taking place is shattering temperature records from Europe to Asia.

Coal-fired power plants emit large amounts of carbon dioxide, sulfur dioxide, nitrogen oxides, and toxic heavy metals like mercury. The plants drive global climate change, create smog and acid rain, and produce millions of tons of toxic ash that can pollute local water supplies.
