The uncertainties around solar power are well understood — when the sun doesn’t shine as much as expected, power grids that rely heavily on that generation must turn elsewhere to meet consumer demand. And while a shortfall in solar generation can be challenging to navigate, the difference between actual and forecast levels is typically only a few percentage points and power grids are usually ready and able to make up any difference. But what happens when the sun is largely obscured by the moon for several hours across a wide swath of the country? In today’s RBN blog, we’ll discuss the impact of the October 14 partial eclipse, preview the path of the April 8 total eclipse, and outline the steps being taken to ensure that power grids are ready for it.
The uncertainties around solar power are well understood. When the sun doesn’t shine as much as expected, power grids that rely heavily on solar must turn elsewhere to meet consumer demand. And while a shortfall in solar generation can be tricky to navigate, the difference between actual and forecast levels is typically only a few percentage points, and power grids are usually ready and able to make up any difference. But what happens when the daytime sun is obscured for hours at a time? Much of the U.S. is about to find out. In today’s RBN blog, we’ll preview the path of the October 14 solar eclipse, detail its expected impact on the generation of electricity, and describe what steps are being taken to keep power grids performing as usual.
Discussions about electric vehicles (EVs) often focus on the additional demands they will put on the power grid in future years, with concerns about the grid’s reliability and ability to meet peak demand often taking center stage. There’s no doubt that a widespread transition to EVs would pose real challenges, but utilities in California and elsewhere are also starting to think creatively about how to transform those challenges into an opportunity — although there are significant hurdles to clear along the way, including the needed buy-in from EV owners. In today’s RBN blog, we explain California’s so-called duck curve, show how certain EV solutions aim to address some of the power grid’s current problems, and look at some ways to get EV drivers to become active (and willing) participants in a vehicle-to-grid (V2G) initiative, which increasingly looks like an essential element in any long-term plan.
Since the first OPEC oil embargo nearly a half-century ago — and more recently with Russia’s invasion of Ukraine — energy producers and consumers alike have learned important lessons about the significance of energy commodity sourcing. It all comes down to this, really: (1) know what you’ll need going forward; (2) diversify your sources of supply, focusing on suppliers who are reliable and friendly; and (3) don’t screw up by becoming overly dependent on suppliers who could prove to be sketchy. For decades, the industry’s focus was on oil and gas — which is still critical, as Europe knows all too well. But as policymakers attempt to transition to renewables and electrification, a whole new set of commodity-supply concerns is coming to the fore. In today’s RBN blog, we discuss the challenges associated with securing the key materials required to build the machinery of the energy transition.
