The long-awaited rains in Australia that have provided relief to the bush fires are having a deadly side effect by creating toxic water systems that have killed fish and put other wildlife at risk. Thousands of fish have been found in the Macleay River in New South Wales. This was a fear of researches who suspected this may happen. This is likely caused by the rain carrying charred debris into rivers through dams and into the ocean

Pleasantly called natural gas and sold to many as a better solution, a good transition fuel, natural gas has been dominating new US electricity capacity alongside renewable energy. Yet, hydraulic fracking absolutely takes the "natural" out of it. Originally, natural gas was successfully sold as a cleaner transition fuel. Who knew there were not even laws on the books to address the hidden pollutants, and that there would be much information lacking about the truth of the acid stimulation, hydraulic fracturing, and other new extraction technologies

When people ask the question, “what could I do to help save the planet?,” it is all too often on the same level as the whiny kid being asked to take on some responsibility. Those of you who have had, or still have, teenage children will know the kind of scenario

It seems like a lifetime ago when at the Rio Earth Summit in 1992, I watched more than 100 heads of state and government queue to sign the original documents of the Framework Convention on Climate Change, the Biodiversity Convention and Agenda 21. Negotiations had been tough, and some leaders were more enthusiastic than others

Let's talk about lithium production. Lithium is the first member of the alkali metal family — elements that make up Group 1 (IA) of the periodic table. Lithium is also the least dense of all of the metals in its group, with a density of about half that of water. It has many uses, including in batteries

Pumped storage hydro has far more resource potential than required for a fully decarbonized grid and it's cheap per megawatt-hour (MWh) of storage. The downside is that it's slow to build, capital intensive, and heavily regulated right now in the United States. The Department of Energy FAST program aims to change that

One of the key take aways from the wind industry experience is that assuming that you have social license because of the virtuousness and safety of an electrical generation technology is a big mistake

Washington State Ferries will be following Ellen's example near the Danish island of Ærø. Washington often leads and succeeds where other states hover, discuss, and are quite too slow to transition. Washington also runs the second-largest ferry system in the world, so switching from diesel to batteries in the early part of a trend toward electrification in shipping is vital to set better standards in marine shipping

Long Tesla Supercharger lines are just like long lines anywhere: frustrating. Especially if you have to wait in line longer than it takes to charge. This problem came around the Thanksgiving holiday season and may pop up again around Christmas and New Year's. After all, many people travel for the holidays
