“What is the simplest type of Solar Controller?”

 

Solar Controllers come in all different types of varieties. But if we are strapped on finances, what is the simplest one that we can make? Well, wouldn’t it be a solar controller that simply turned on when there was sunlight and the battery was not full and off when not? This is the basics behind On/Off Solar Controllers, which are commonly used for inexpensive setups.

“Why do some U.S states like California have a much lower energy consumption rate than others?”

 

Hello everyone, in honor of my recent acceptance to work in the buildings energy department at Berkeley Lab, I’ve decided to write about one of its most important humanistic accomplishments.

 

In the midst of the 1970s, there was an energy crisis happening all around the world. In response to the outcome of the 1973 war, OPEC states had begun an oil embargo to the U.S and its allies. This caused energy prices to skyrocket and supply to dwindle, having tantalizing effects on the world economy. In the U.S, these wounds were worsened by the continuous increase in energy that had been running for decades. Governments had looked to all sorts of solutions. In California, then (and now present) Governor Jerry Brown was considering building a series of new power plants to revive energy production. But he was soon approached by a prominent scientist from Lawrence Berkeley National Laboratory named Arthur Rosenfeld, who had a completely different but more logical solution. Instead of creating more energy production, why not simply consume less of it? Once adopting this idea, the state of California experienced something very peculiar. As the energy consumption of the rest of the nation rose with time, its own energy levels have stayed relatively flat since the 1970s! This empirical fact is known as The Rosenfeld Effect and is a prominent example of the success of energy efficiency.

“What does New York’s new energy efficiency target entail?”

 

In recent news, New York Governor Andrew M. Cuomo has launched an ambitious energy efficiency plan for his state. New York civil infrastructure and policy will now be structured such that the state will reduce 1/3rd of the greenhouse emissions. Earth Day will be used as the annual marker for energy reductions.

“Why is it when offshore wind turbines get larger they have to be split up into more components?”

 

Offshore wind turbines are the future of wind energy. Their ability to be built larger and capture greater winds makes their traditional counterparts look feeble in comparison. However, with this increased size comes increased complexity, which extends to its assemblage. Engineers now have to make new procedures to move around these heavier parts or split them up into multiple components to comply with maximum weight regulations. As such, the increasing size of offshore wind turbines is affecting their assemblage

“How will people trade energy in the future?”

 

With the developing distributed energy world, energy transmission will now take place bidirectionally. One consequence of this is that people will be able to buy and sell energy from one another instead of the utility in a form known as transactive energy. Like online retail for consumer products, transactive energy will enable homeowners to barter and profit from self-generated renewable energy.

“Can Solar Plus Storage make the grid obsolete?”

 

In the 20th century, back when we were reliant on massive power plants to produce energy, if you wanted to have electricity in your home then you had to sign up an electrical utility. But with the advent of Solar Plus Storage Systems, this might become a thing of the past. Now that people can not only generate but store their own electricity at their home, there is no longer a need to be attached to the grid. In some cases, it’s actually cheaper to become off-grid! As a result, many people are undergoing grid defection and turning to generate their own electricity.

“How can we create a central management system for distributed energy resources?”

 

Without a doubt, distributed energy resources are the way of the future. With their ability to efficiently generated clean and renewable energy in optimal locations, they can make a truly sustainable civilization possible. However, if left unregulated, they can wreak havoc on the grid, and destroy an efficiency associated with them. So how can we use our engineering mindsets to solve this problem? Well, what if we were to create a centralized control system that could monitor and actuate upon these systems? Well, this is the main idea behind Distributed Energy Resource Management Systems, and are a very hot topic for the future of energy research!

“How can we charge a device without a cord?”

 

When we think about charging electrical devices, we typically think of using a huge power supplying power cord. However, is it possible to charge without having any physical connection? Well, let’s use our engineering mindset to figure it out. We know that if we were to take two inductive coils, put them close together, and send an electric coil to one, then a current will be induced in the other. So what if we were to have a station with one inductive coil, and a device with another, every time the electromagnetic activity of the station can induce a current in the other? Well, this is known as wireless charging and is a very rapidly developing technology, with voluminous implications for both electric vehicles and cell phones.
