Most people consider algae a nuisance. But it turns out that one man’s pond scum is another man’s gold, to draw on an old expression. An algal species with the right properties could be immensely valuable. That’s why we and others at the National Renewable Energy Laboratory, in Golden, Colo., have been busy “bioprospecting” for promising scoops of slime.

Cutting Carbon Emissions Is Harder Than the Glasgow Climate Pact Thinks

The COP26 demands that we reduce global emissions by two-fifths in just nine years

Three months ago the Glasgow Climate Pact (COP26) declared that by 2030 the world must cut total carbon dioxide emissions by 50 percent relative to the 2010 level, which was 30.4 billion tonnes. This would bring annual emissions to less than 20 billion tonnes, a level last seen more than 30 years ago.

What are the chances of that? Let’s look at the arithmetic.

Electric utility infrastructure habitually falls prey to overgrown Right-of-Way, high winds, and harsh weather. Impactful events causing outages are increasing in frequency, and need to be endured without major disruptions in electric service. This webinar will discuss the application of covered aerial conductor to "harden" the electric utility grid so that unpredictable events don't result in unsustainable outages.
