Renewable Energy

Hyperscalers are large technology companies that build and operate massive, globally distributed data center networks to provide cloud computing, storage, and networking services on an enormous scale. Examples include Amazon, Google, Meta, Microsoft, and Alibaba.

The offshore Revolution Wind project, located off the coast of Rhode Island, is nearing completion after nearly three years of work. The project is 95% complete, with 61 out of 65 turbines fully installed.

The elimination of federal tax credits for solar installations and electric cars have wreaked havoc with sales for these green energy technologies. The Republican Congress voted to have these credits expire at the end of last year. People raced to lock in good deals on both EVs and rooftop solar. Then, with the arrival of the new year, sales cratered – at least for a while.

An energy roundtable in Plattsburgh, New York, Friday brought together labor, utility and conservationists to discuss energy needs in the North Country

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.

Climate Solutions Week explores different environmental challenges and solutions including: a sustainable fashion runway, a how-to on disposing of refrigerators, a heat pump demonstration, and discussions about data centers.

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.

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.

Fusion power is how the sun works. Light atomic nuclei (like hydrogen) fuse together at super high temperatures to form heavier nuclei (like helium). The process releases massive amounts of energy without producing radioactive waste or greenhouse gases. Fusion is considered to be the holy grail of clean energy. But even after many decades of intensive research, there is not yet a way to maintain the temperature, density, and confinement to have a fusion reaction go on long enough to produce continuous net-positive energy output.
