Energy deregulation gives consumers choices when it comes to the companies that provide their home electricity. Suppliers can compete for your electricity dollars in a variety of ways, offering low prices, short and long-term contracts, fixed or variable rates, and a choice in how your energy is generated. The sheer volume of options can seem so complicated that you need to ask an electrician to help you tangle out the pros and cons of the available plans. One area in particular that can trip up consumers has to do with whether the source of their electricity is green or renewable. Read on to learn the difference.

Green Customers are Loyal Customers

Currently, 15 states plus Washington, D.C. have active electricity deregulation programs, according to the U.S. Energy Information Administration, and these states are largely concentrated in the Northeast. Consumers who live in deregulated states are likely to be flooded with energy offers, often promising electricity that is derived from green or renewable sources. Purchasing this environmentally friendly power usually costs a bit more than electricity that comes from more traditional sources like coal, but some homeowners like to put their money where their mouth is when it comes to reducing carbon emissions.

Those customers who go green are valuable to the supplier because they are less likely to jump ship based on the availability of a cheaper energy source. "A customer on a renewable-energy product has actively decided what is important to them and has selected their supplier accordingly," Ritchie Hudson, Pennsylvania chairman of the Retail Energy Supply Association, said to the Philadelphia Inquirer.

A Question of Semantics

However, while many suppliers and consumers treat green and renewable sources of electricity as synonymous, there is a distinction. Green energy is that which comes from specific sources that have the highest environmental benefit, including solar, wind, geothermal, biogas, eligible biomass and small hydroelectric sources, according to the Environmental Protection Agency. Meanwhile, renewable energy “includes resources that rely on fuel sources that restore themselves over short periods of time and do not diminish,” which includes all the green options but also other sources such as large hydroelectric dams, which present certain environmental tradeoffs.

That means that if you really want to limit your impact on the Earth as much as possible, go green in lieu of simply choosing renewable energy. You can further refine your choices by asking about the specific source of the electricity, if you have a preference for solar, wind or another option.

Ask an Electrician About Your Options

Deregulated energy markets give you flexibility, but can also sow consumer confusion. If you need help deciphering the offerings of your state's electricity providers, ask an electrician who can walk you through your choices.

Electricity is an important part of our life. However, when it comes to electricity distribution, it needs to be done in a safe and secure manner. It entails several handling hazards, which, when not done safely, can easily turn into a deadly trap. There are times when accidents and mishaps happen due to the lack of safety at different power distribution units.

Therefore, to maintain the security levels at all distribution units and sub stations, it is critical to install safety devices and mechanisms. While there are many mechanisms that help in safeguarding electrical connections at residential and industrial areas, switchgear is one of the most popular ones due to its various functions and features.

Analyzing switchgears from the perspective of commercial, industrial, and institutional MV (medium voltage) distribution system, its functions are as follows:

Types of Switchgears

There are two main types of switchgears which are necessary for various commercial, residential, and industrial electrical connections. They are:

2. Ghosts in the yard.

If you have handy lights lining a path or driveway at your house, this idea will take no time at all. You just need to collect a bunch of old plastic milk jugs with the tops cut off or white paper bags (I suggest making the decision after you get the weather report for All Hallows’ Eve). Simply draw eyes on the jugs/bags with a black marker, and slip them one by one over each Image via MarthaStewart.com

Here’s an ultra affordable Halloween lighting project, if your preferred poison is the frightening beyond of unexplained extraterrestrial phenomena. Just fill your house (or yard) full of anchored helium balloons containing green glow sticks. Add faces with traditional alien eyes or something even more creative! If you really want to play it up, you and your family could dress up like extraterrestrials and pretend the real you has been abducted.

4. Mini mummies.

If you prefer cute décor over the more macabre, a quick project to make mini mummy candles holders only requires a jar or glass cup, some white gauze, and some googly eyes. Simply scrunch up the gauze around the jar to look like the mummy’s linen wrappings. Add the eyes, and ta-da, you’ve got a precious little mummy come back to life with candlelight. They’re a crowd pleaser, trust me.

Automation lies at the core of much of our modern lives. However, it evolves at radical speeds. The simple concept, to build a machine to perform a task without human intervention, was the engine of the industrial revolution. Now that concept is the driving force behind robotics, self-driving vehicles, and a wide range of advanced technologies.

Most automated tasks are part of a closed-loop system. This system is designed so that the outputs are monitored and fed back to the controller. The controller changes its operation as needed. An example of a closed-loop system is a home thermostat, which monitors the air temperature. When the low set-point is reached, a contact closes in the thermostat, beginning a furnace lighting cycle. As the furnace runs, the room air temperature increases until the high set-point is reached. The contact opens and ends the furnace burn cycle. This is automation.

With electrical relays, it is possible to achieve a variety of automatic functions. A motor starter uses a relay to close a contact that sends electrical power to a motor. In addition, it closes a set of auxiliary contacts that keep the main relay closed. A control mechanism, such as a temperature input or a stop button, can be wired in series with the auxiliary contact. This allows for control of the motor. An expansion of relay logic is the programmable logic controller or PLC. Instead of mechanical relays, a PLC uses a set of input and output contacts connected to a computer controller. Software in the controller then dictates how the inputs and outputs interact. They additionally execute specific patterns of operations, based on programmed ladder logic.
