Boilers obviously play an important role in the power generation industry, providing the mechanism to convert heat produced by burning fuel into steam that can be used to drive a turbine to generate electricity. But many other industries also use boilers to produce steam for a variety of purposes. Boilers are commonly used for space […]

Life cycle analysis or assessments (LCAs) are a quintessential tool for power and utility industry professionals and tradespeople. They determine the environmental and financial value of new technologies. Consumer products get the most attention, but LCAs for renewable energy systems (Figure 1) should be discussed more. It is time to synthesize known information to create […]

Negotiators from nearly every country in the world closed COP28 with a decision that—for the first time—formally recognizes the necessity of moving away from fossil fuels to achieve Paris Agreement targets. The decision, adopted on the last day of the two-week 28th Conference of the Parties (COP 28) to the UN Framework Convention on Climate […]
