Renewables require change in the energy supply chain.

Subscribe to our channel! http://goo.gl/0bsAjO

Electricity is incredibly difficult to store, so grid operators have to generate it at the exact moment it is demanded. In order to do this, they create incredibly accurate models of the total electric loads, that is how much energy will be consumed on a given day. But as utilities started to produce more energy from renewable sources like solar, the models started to shift as well.

California researchers discovered a peculiarity in their state’s electric load curves, that started to look more and more like a duck. And that duck shaped chart highlights the greatest challenge to solar energy growth in the US.

Vox writer David Roberts has been covering the issue for a few years now. You can read some of his past explainers on the duck curve, and its solutions at the links below:

The bizarre physics of fire ants

They're not just an animal, they're a material. And that's got engineers interested. // Subscribe to our channel! http://goo.gl/0bsAjO For more information about the Hu lab: http://www.hu.gatech.edu/ Red imported fire ants (solenopsis invicta) are native to South America and an invasive species in the United States. One of the adaptations that makes them so hardy is that they can build large structures by linking their bodies together. This is how they form rafts that can float during floods. When they're aggregated together, fire ants can be seen as a material and the Hu lab at Georgia Tech has been testing that material for years. /// Vox.com...

Nuclear Fusion Energy: The Race to Create a Star on Earth

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy. We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

The high cost of free parking

Hidden parking rules hurt our cities. Will Chilton and Paul Mackie of Mobility Lab explain. Subscribe to our channel! http://goo.gl/0bsAjO The cities we live in are shaped by the way we get around them. Over the past 60 years, with more and more people opting to drive cars, the need for parking spaces has increased with the boom in driving. To accommodate that demand early on, cities and towns started requiring developers to include parking with their new buildings after World War II. These policies, known as mandatory parking minimums, set precise standards for parking spaces for each building. And these...

Why America still uses Fahrenheit

Fahrenheit, explained to the rest of the world Since I've moved to the US in 2010, there's one thing that I still don't fully understand: the imperial system. Virtually every country on earth uses Celsius but America has yet to follow. Although it might not seem like a big deal, not using the metric system puts America at a great disadvantage. For example, American kids have to learn 2 sets of measurements making science education even more difficult. On top of that, American companies have to produce extra products to export to metric countries. So why does the United States still...
