“How does a flat rate work for electricity usage?”

Utilities produce revenue through electricity tariffs. Although not the simplest, another simple type of tariff is the Flat Rate Tariff. Despite the name, these tariffs still charge in proportion to electricity usage. Rather, they are called flat rate since they do not discriminate based on time of use. What differentiates flat rate tariffs from simple tariffs is that they can distinguish between different types of consumers, such as residential or commercial. The advantages of flat rate tariffs is their simple implementation, while their primary drawback is their inability to incentive different times of use, a necessity to mitigate the duck curve.

“What is the simplest type of energy tariff?”

In order for energy companies to survive, they need to find a way to charge money for the energy they produced. This is usually done through an Electricity Tariff. The most simple type of electricity tariffs is known as Simple Electricity Tariffs. These tariffs simple charge money in direct proportion to energy consumed. The advantages of this is that it simple, easy to understand and implement, and directly responds to how much electricity is used per-capita. However, the drawbacks is that these tariffs cannot be tailored to specific group’s needs, which can lead to higher cost, provides no incentive to consume more electricity, and if no electricity is purchased during the month then the utility can die.

“How can rooftop solar be utilized for the grid’s needs?”
Rooftop solar is one of the fastest growing types of distributed energy resources. However, right now they are only used to provide power to the buildings of the owner. But what if we could use that extra energy to provide power for the grid? This would increase grid flexibility and allow for further decarbonization. This is How Rooftop Solar Can Be Used a Grid Resource.

“Why is undergrounding power lines not recommended for flood-prone areas?”

Undergrounding power lines is a recommended course of action to build resilience against forest fires, storms, and heavy winds. However, this also makes them more prone to flood damage, as they will become submerged in water in the event of one. This is Why Undergrounding Transmission Lines Makes Them More Vulnerable to Flood Damage.

“How do we design cities and municipalities?”

Today, around 55 percent of the world lives in urban areas and that number is rapidly growing. That means as cities expand and new towns are built, there must be significant planning done to ensure livability and proper operation of all infrastructure, whether it be in transportation, utilities, or amenities. This can be accomplished through the use of Urban Planning, or the study of how to design urban conglomerates.

“How can a large-scale power outage occur from just a single component failure?”

The modern power grid is a feat of human ingenuity. One of the most interconnected systems in existence, it allows for terawatts of power generated to reach millions of consumers. However, this great interconnection comes with one drawback. If even one component fails, then the additional stress on other parts can cause more failures which can cascade until a completed blackout occurs. These Cascading Power Failures are a utility’s bane and resilience strategies must be developed to counter the probability of these events.

“Why would microgrids be helpful to protect against floods?”

With the advent of climate change, ocean levels are rising and storms are becoming more powerful. This will make floods occur more frequently, causing continued devastation to critical infrastructure such as the grid. In order to continue to live in this new world, communities will need to adapt their infrastructure around this new reality. One way to accomplish this is to implement microgrids. When the main power system shuts down, batteries and distributed energy resources can ensure that electricity stays running. This is Why Microgrids Would Be Great for Flood Resilience.

“How can we predict the value of an item at the end of its lifetime?”

Due to the second law of thermodynamics, materials are bound to degrade over time, lowering both its function and value. Since an item might become less worthy in the future, then it would be very useful to know how it will change. Through analytical modeling and past experience, we can calculate something the Residual Value, or final worth of a product. Many leasing companies will calculate monthly payments based on this final value.

“What are the dangers of liquid hydrogen fuel in vehicles?”

Hydrogen fuel cell vehicles are a very hot research topic. However, liquid hydrogen vehicles present some strong dangers. Although sealed hydrogen is relatively safe, exposed hydrogen has some factors which can make it less so. First of all, hydrogen can catch fire really easily as it only requires 1/10th of the energy to combust compared to gas. Hydrogen flames are also nearly invisible and can displace oxygen in human lungs, making it a very silent killer. This is Why Liquid Hydrogen in Vehicles Can Be Very Dangerous.
