Cost-Effective Window Inserts Can Insulate Older Windows Without Replacing Them (Review)

Older windows can be a huge waste of money when you try to heat or cool your home. R values (a measure of insulation, measured in "resistance" of heat passing from one place to another) are very, very low for older windows. Whereas your walls might have an R value of 20-40, depending on local zoning codes, how well built your home was, and how much insulation was added, your windows might have an insulation value of 1 or 2.

A Simple Model Could Predict The Future Of Solar PV Adoption

Utilities across the U.S. are eager to know how much PV their customers will adopt, as this adoption can impact both revenues (from reduction in energy purchases) and costs (linked to distribution operation and intermittency mitigation). Having seen the explosive growth of PV in a few key states across the US, the majority of utilities are heeding the warning of their peers and preparing for similar adoption in their own territories

Explained: Neural networks

In the past 10 years, the best-performing artificial-intelligence systems — such as the speech recognizers on smartphones or Google's latest automatic translator — have resulted from a technique called “deep learning.” Deep learning is in fact a new name for an approach to artificial intelligence called neural networks, which have been going in and out of fashion for more than 70 years. Neural networks were first proposed in 1944 by Warren McCullough and Walter Pitts, two University of Chicago researchers who moved …

Three Examples of How Demand Response Is Morphing as a Grid Resource

As utilities and grid operators face new flexibility challenges, demand response is more important than ever. Applications for demand-side resources are evolving as a result. There are a handful of themes emerging from the industry worth exploring: a strong focus on customer engagement; a growing array of demand response resources; an increased focus on non-wires alternatives to infrastructure; and the slow progress when turning pilots into commercial programs. A community of thought leaders, utilities, …

Water, water everywhere … even in the air

Severe water shortages already affect many regions around the world, and are expected to get much worse as the population grows and the climate heats up. But a new technology developed by scientists at MIT and the University of California at Berkeley could provide a novel way of obtaining clean, fresh water almost anywhere on Earth, by drawing water directly from moisture in the air even in the driest of locations. Technologies exist for extracting water from very moist air, such as “fog harvesting” systems that have …
