Producing power from the wind and sun isn't as simple as just swapping a wind turbine for a coal-fired power plant. Every source of power we use has to work with our electrical grid, an old, imperfect, complex system that wasn't put together with the needs of renewables in mind. For instance, because renewable generation is intermittent generation, using it goes hand-in-hand with ramping production from traditional generation up and down. When you don't have enough wind, you turn up the gas-fire generators. That kind of treatment can put stress on machinery and rack up costs in maintenance and repairs. But new research from the National Renewable Energy Laboratory suggests that, at least in monetary terms, those costs are dwarfed by the cost savings you get from using more wind and solar power and, thus, not having to pay for fuel sources.
Antti Lipponen of the Finnish Meteorological Institute created this troubling but unsurprising chart of almost 140 years of temperature anomalies by country. The data used was from the NASA GISS, Land Ocean Temperature Index. You can probably guess what will happen.
NASA’s AIRS instrument captured this image of Tropical Storm Fay around 2 p.m. local time on July 10, 2020, as the storm swept through New England. Image: NASA/JPL-Caltech From NASA’s Jet Propulsion Laboratory: Tropical Storm Fay is sweeping across New England, with the center of the storm making landfall about 10 miles (15 kilometers) north-northeast […]
The deadly 2013 El Reno tornado was 2.5 miles (4 km) wide and killed a team of tornado experts. But as Anton Seimon explains, his colleagues turned that tragedy into an opportunity to confirm a key element of tornado formation.
The average US household replaces their mattress about every seven years. So if it’s been more than that, or even a lot more than that, it might be time to invest in a new slumber HQ. And most sleep experts will tell you the right mattress really should be looked at as an investment. Because […]
If there’s any knock on most smartwatches, up to and including the industry-leading Apple Watch, it’s probably that the bands aren’t…well, they aren’t usually the greatest. While Apple is certainly making strides in the watchband game, most models are just as black, boring and nondescript as you’d expect from a tech company. And where many […]
For all their obvious similarities, language learning apps will often each take unique approaches to teaching a foreign tongue. Or, in the case of many services, a whole bunch of foreign tongues. While some providers give you access to training across overwhelming menus of more than 150 different languages, the people behind the Busuu Language […]
