Much of the discussion about the benefits of electric vehicles centers about the climate impact of not burning fossil fuels as well as about reduced operating costs. A new study by the University of Toronto looked at the health benefits of large-scale adoption of electric vehicles. The Toronto researchers used computer simulations to show that […]…

Lithium is the critical raw material in the batteries that power electric cars as well as cell phones, computers, and other gadgets. The stuff has been nicknamed “white gold” for good reason. Chile and Australia are the world’s largest producers of the metal, which is mostly extracted from brine in evaporation ponds. The majority of […]…

The global shipping industry is responsible for 90 percent of world trade. The ships crossing the world’s oceans emit nearly 3% of the global greenhouse gas emissions caused by human activity that are contributing to climate change. Among the effects of climate change are sea level rise, which is threatening the very existence of small […]…

Per- and polyfluoroalkyl chemicals, more commonly known as PFAS, are a family of human-made chemicals that have been manufactured and used in a variety of industries since the 1940s. They provide water-resistance, oil-resistance, dirt-resistance, and corrosion-resistance to a wide range of products, including food wrappers and packaging, clothing, …

Researchers predict that climate change will negatively impact the yield and nutritional quality of most staple food crops, including rice, corn, and soybeans, due to factors like extreme weather events, rising temperatures, and altered precipitation patterns, potentially leading to reduced food security globally. As a result, many experts contend …

One of the largest solar projects in the US has recently come online in Texas. Three solar farms built side-by-side in Buckholts, Texas by SB Energy can provide 875 megawatts of electricity, nearly the size of a typical nuclear power plant. The project will supply the largest solar energy purchase ever made by Google and […]…

Wildlife trafficking is the world’s fourth largest form of organized crime, behind only drug trafficking, counterfeiting, and human trafficking. When we hear about wildlife trafficking, we think of elephant ivory, rhino horns, tiger parts, and the like. But so-called forest crimes, which includes poaching protected trees and illegal logging added u…

People’s views and level of concern about climate change tend to vary according to age, political affiliation, and other demographic categories. But one clear trend is that young people are overwhelmingly concerned about climate change. Given that they will ultimately suffer from its effects far more than older generations, this is not really surpr…

The US is the world’s largest user of nuclear power. Its 94 reactors supply nearly 19% of the country’s electricity. But the number of U.S. reactors has steadily fallen over the past 30 years and new nuclear power plants are a real rarity. The reasons are a combination of perceived dangers following several nuclear accidents […]…

According to the U.S. Department of Energy, the United States is the world’s largest producer of natural gas. In fact, natural gas supplies approximately one third of the United States’ primary energy consumption, most of which is used to heat buildings and to generate electricity. While most natural gas is delivered in its gaseous form […]…

Cement production accounts for about 7% of global carbon emissions. It is one of the most difficult challenges for emissions reduction. The emissions associated with producing cement come from both the energy used to provide heat for the process and from the chemical reactions that take place in the formation of cement. Cement is an […]…

Vast areas of South America have been gripped in drought conditions for months. Rivers in the Amazon basin fell to record-low levels in October. The drought has amplified wildfires, parched crops, disrupted transportation networks, and interrupted hydroelectric power generation in parts of Brazil, Bolivia, Colombia, Ecuador, Peru, and Venezuela. Th…

Energy storage is a critical aspect of modern energy systems as they move towards heavy dependence on renewable sources such as solar and wind that don’t produce energy at the same rate all the time. Excess energy generated by solar power needs to be stored for when the sun isn’t shining; excess wind energy needs […]…

The U.S. has nearly half a million school buses providing daily transportation for about 20 million students. Most of these buses are powered by diesel engines which not only dump greenhouse gases into the atmosphere but also fill kids’ lungs with harmful fumes. Thanks to various federal and state incentive programs, this situation is starting […]…

People in remote, low-income regions far from the ocean often need to meet their water needs from groundwater and groundwater is becoming increasingly saline due to climate change. Desalination of brackish groundwater is a huge and largely untapped source of drinking water, but there are challenges in making the process efficient and reliable. Engi…
