A curious thing recently happened in Southern California. One of the largest utilities in the country scrapped a proposal to build a new peaker plant, opting instead to build a battery system that could store excess electricity from solar and … Continue reading
This groundbreaking new project in Germany is testing the use of salt as an ingredient for a fossil fuel-free future.
The Reuter power plant in Berlin recently launched a new system of technology that is using calcium oxide, also known as quicklime, to store heat for long periods of time.
Germany already has the renewable energy capacity to power more than half of the country, but since many green energy sources are dependent on consistent weather conditions, the nation is forced to continue using fossil fuels as backup energy sources.
Quicklime, on the other hand, generates large amounts of heat when it is simply exposed to water.Continue reading
Texas, home to the world’s largest oil reserve and America’s biggest source of coal-fired power, is on the verge of a clean-energy boom. Wind already supplies about 15 percent of Texas’s electricity, and now developers are about to quadruple the … Continue reading
The US Army is not particularly shy about adopting the latest high-tech gadgets, and renewable energy is a case in point. Despite all the fossil friendly rhetoric emanating from the White House, the Army is still pursuing microgrids with renewable … Continue reading
Whale blubber and buggy whips were once fine industries, but progress moved us away. And today we know the days are over of a false choice between environmental protection and economic growth. Since when did the simple concept of leaving … Continue reading
History shows whale blubber and buggy whips were once fine industries, but progress moved us away. And through progress today we know the days are well over of a false choice between environmental protection and economic growth. And similarly it’s … Continue reading

We have many ways of measuring methane and CO2 levels. When we measure it we can manage it…if we really want to know and manage it. Polluters can’t hide anymore. Source: Meet the Satellites That Can Pinpoint Methane and Carbon … Continue reading
San Antonio’s public utility, CPS Energy, faced blowback from city leaders and environmental groups Thursday on its newly released strategic power plan that takes decades to fully transition to renewable sources of energy. “A lot of folks felt blindsided by … Continue reading
Renewable energy might be clean, but it's not always reliable if the Sun ducks behind clouds or the wind slacks off. To counter that variability, the grid will need to combine a range of different sources, such as solar, wind, … Continue reading
Across the U.S., energy users of all sizes are taking control of their power supply and relieving stress from the grid. That’s the idea behind distributed energy. Atlantic Re:think and Siemens partnered to explore this burgeoning energy revolution in 360º … Continue reading
Members of a local energy-efficiency initiative collectively reduced their carbon impact by more than 10,200 metric tons of carbon dioxide in 2016, according to an annual report from San Antonio 2030 District, which is leading the effort. The initiative, led … Continue reading
Last week, I walked into the San Antonio City Council Chambers to present the Council members with nearly 700 petition signatures urging them to press forward with their pledged commitment to develop a Climate Action Plan for the city. While … Continue reading
The country’s energy mix is under scrutiny. A report commissioned by Energy Secretary Rick Perry acknowledges that low natural gas prices—not renewables—are behind the recent closure of coal energy plants, and that the grid has managed to withstand the increasing … Continue reading
