Energy Storage as a Service

“How can we turn energy storage into a business?”

 

Traditionally, facilities had only two options for receiving electricity, generating their own or purchasing from a utility. But with the advent of renewable energy and advanced energy storage, this picture is starting to change. Facilities can now enter contracts with organizations to receive energy from energy storage systems. This venture known as Energy Storage as a Service has the potential to generate revenue, create savings, and improve electricity resiliency by providing clean energy at affordable rates

“What is the link between food, water, and energy?”

 

Although commonly thought of as separate issues, our use of food, water, and energy are actually highly interrelated. For example, agricultural produce is the largest consumer of freshwater resources and takes up to a quarter of energy use, while outdated energy generation techniques such as fracking consume a voluminous amount of water during operation. Because of this, the United Nations has created the concept of  The Water-Food-Energy Nexus to educate people about this phenomenon. This problem will become more apparent with the advent of an increasing population.

“How can Neuroscience impact economic theory?”

 

Neuroscience is one of the fastest expanding fields of science. And its findings have serious implications for other fields of research, far and wide. And one of these includes something not usually thought of as being related, economics. Since economics is becoming increasingly driven by how humans make decisions, one of the factors is must consider is the operating framework of the mind. As a result, the field of neuroeconomics has been born, which has serious implications for the future of the study of human behavior.

“What is the official building energy efficiency standard for California?”

 

In the U.S, most building efficiency standards are regulated by ASHRAE 90. However, some states go a little bit further with their regulations. In California, a series of codes known as Title 24 is the law of the land. Title 24 contains all of the specifications that a construction firm must consider before going through with a project. These include a requirement for LED lights, motion sensors for buildings, a specified minimum reflectivity for roofs,  electrical service panels for disaggregated measurement, and many other variables. California Title 24 is updated every 3 years such that the next set of rules saves more energy than the last.

“What is the basis for building energy efficiency in the U.S and much of the world?”

 

With the onset of global warming, energy efficiency has become a great necessity. As such, buildings in the U.S must now follow a certain standard so that after construction they will meet the sustainability requirements dictated by ASHRAE Standard 90.1. ASHRAE Standard 90.1 is a compilation of all of the codes for building energy efficiency (with the exception of low rise residential units) and is updated every three years to ensure that the next set of codes will be 15 percent more efficient than the previous.

“What happens to electronics when they wear out?”

 

Electronics are embedded into the fabric of everyday life. Whether it be in the computers we work with, the batteries to run our cars or the smartphones that we use to communicate with our friends. However, after a while, these items will become worn down by continual use and must be discarded.  So how exactly does the waste process for electronics work?

 

Before we begin any process, we must recognize that electronics have toxic chemicals. These chemicals make it particularly difficult for dealing with electronic waste in any normal sort of fashion since improper disposal in a landfill can wreck hazards on the local environment. Since electronic waste fits into its own special category, such material has been labeled as E-waste.

 

To properly get rid of E-waste, individuals must bring it to a special E-waste processing facility. These units can intake all discarded electronics such as monitors, cell phones, radios, televisions, and computers and recycle all useable parts. E-waste facilities are a great way to deal with hazardous electronic waste.

“How can we maximize or minimize a set of linear equations?”

 

Often times, when working on problems, we have multiple variables related by multiple equations. For example, let’s start out with this situation. Let’s say we have two machine parts x and y that cost 2 dollars and 5 dollars to make respectively, symbolically p(x,y) = 2x + 5y. And let’s also say that we have to make a total of 100 machine parts respectively, or x + y = 100 (blue). And let’s also say that 202 times the number of part x and 5 times the number of part y must be equal to 1400, or 20x + 5y = 1400 (green). So how can we find the minimum price that meets all of our production needs? Well, let’s plot it on a graph (pictured), check all of the points of intersection (In this case (0,100), (60,40) and (100,0) ), and then see which of these points return the minimum desired quantity (In this case (0,100) –> $200). Linear programming can be applied to all forms of applications, ranging from engineering economic systems to control theory and even to general business!
