“How can we use sensors to synchronize the grid?”

 

The electric grid is one of the modern technological wonders of the world. However, its dynamism means that it often goes out of sync. To solve this, utilities can place Phasor Measurement Units onto the grid that can estimate the magnitude and phase angle of current or voltage.

Why Dry Climate Snow is Different From Humid Climate Snow

“Why is dry climate snow different than humid climate snow?”

 

An area’s climate affects everything, and the snow is no different. In humid climates, which tend to be closer to a body of water and lower in elevation, snow tends to be imbued with water, making it extra wet and messy. However, in dry climates, the ice crystals lack this problem and therefore are more tightly bound. This is Why Dry Climate Snow is Different From Humid Climate Snow.

“What is one tough thing humanity needs to adopt to fight climate change?”

 

Right now humanity is on track to shoot past a rise of 2-degree centigrade from pre-industrialization by 2030. And one of the primary reasons behind this is because human energy consumption and population has been rising over the years. Much of the global focus to fight this has been increasing technological energy efficiency. But according to the equation I = PAT, if population and affluence rise then it would offset more efficient technology. If humanity does not want to quickly decrease its population then it must change its culture of affluence. This is A Simple Reason Why Humanity Needs to be Less Wasteful to Curb Climate Catastrophe.

“How can we represent environmental impact based on resource consumption?”

 

Every society has an environmental impact. But since each society has different levels of resource consumption and utilization, each one is different. So how can we quantify this? Well, we can measure impact based on the average of the amount used multiplied by its energy efficiency and the total population. This is known as the I = PAT equation where I is the Environmental Impact P is the Total Population A is the Level of Affluence (how many resources are used) and T is the Technological Efficiency.

“How can superconductors be beneficial for the transmission grid?”

 

Losses by electrical resistance are one of the largest contributors to inefficiency in the power grid system. However, if the normal wiring materials were replaced by superconductive materials which lack any resistance, then this issue would dissipate away.

“How is the US power grid divided up?”

 

The United States is a large country. Spanning between two major oceans, it is truly a wonder to behold. But this might be too large for a single interconnection. Instead, the US is divided up into multiple separate interconnections, which together make up The US Interconnections. It is mainly divided between the Western and Eastern Interconnections, with the Texas Interconnection being a small subset.
