Your Choices for Alternative Energy

While using alternative sources of energy is a right way for you to save money on your heating and cooling bills, it also allows you to contribute in vital ways to both the environment and the economy.  Alternative energy sources are renewable, environmentally sustainable sources that do not create any by-products that are released into the atmosphere like coal and fossil fuels do.

Burning coal to produce electricity releases particulates and substances such as mercury, arsenic, sulfur and carbon monoxide into the air, all of which can cause health problems in humans.

Other by-products from burning coal are acid rain, sludge run-off and heated water that is released back into the rivers and lakes nearby the coal-fired plants.  While efforts are being made to create “clean coal,” businesses have been reluctant to use the technology due to the high costs associated with changing their plants.

If you are considering taking the plunge and switching to a renewable energy source to save money on your electric and heating bills or to help the environment, you have a lot of decisions to make. The first decision you need to make is which energy source to use in your home or business.  Do you want to switch to solar energy, wind power, biomass energy or geothermal energy?

Emissions from homes using heating oil, vehicles, and electricity produced from fossil fuels also pollute the air and contribute to the number of greenhouse gases that are in the atmosphere and depleting the ozone layer.  Carbon dioxide is one of the gases that is released into the air by the burning of fossil fuels to create energy and in the use of motor vehicles.  Neither coal nor fossil fuels are sources of renewable energy.

Replacing those energy sources with solar, biomass, geothermal or wind-powered generators will allow homes and businesses to have an adequate source of energy always at hand.  While converting to these systems can sometimes be expensive, the costs are quickly coming down, and they pay for themselves in just a few short years because they supply energy that is virtually free.  In some cases, the excess energy they create can be bought from the business or the homeowner.

While there are more than these three alternative energy options, these are the easiest to implement on an individual basis.  Other sources of alternative energy, for instance, nuclear power, hydroelectric power, and natural gas require a primary power source for the heat so it can be fed to your home or business.  Solar, wind, biomass and geothermal energy can all have power sources in your home or business to supply your needs.

1. Solar Energy

Solar power is probably the most widely used source of these options.  While it can be expensive to convert your home or business over to solar energy, or to an alternative energy source for that matter, it is probably the most natural source to turn over to.

You can use the sun’s energy to power your home or business and heat water.  It can be used to passively heat or light up your rooms as well just by opening up your shades.

2. Wind Power

You need your wind turbine to power your home or office, but wind energy has been used for centuries to pump water or for commercial purposes, like grinding grain into flour.  While many countries have wind farms to produce energy on a full-scale basis, you can have your wind turbine at home or at your business to provide electricity for your purposes.

The cost of alternative energy systems has dropped sharply in recent years

3. Biomass Energy

Biomass energy has rapidly become a vital part of the global renewable energy mix and account for an ever-growing share of electric capacity added worldwide. Biomass is the material derived from plants that use sunlight to grow which include plant and animal material such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal wastes.

Biomass comes from a variety of sources which include wood from natural forests and woodlands, agricultural residues, agro-industrial wastes, animal wastes, industrial wastewater, municipal sewage and municipal solid wastes.

4. Geothermal Energy

A geothermal heat pump helps cool or heat your home or office using the earth’s heat to provide the power needed to heat the liquid that is run through the system to either heat your home in the winter or cool it off in the summer.  While many people use it, it doesn’t provide electricity, so you still need an energy source for that.

Gasification of Municipal Wastes

Gasification of municipal wastes involves the reaction of carbonaceous feedstock with an oxygen-containing reagent, usually oxygen, air, steam or carbon dioxide, generally at temperatures above 800°C. The process is largely exothermic but some heat may be required to initialise and sustain the gasification process.

utishinai-gasification-plant

The main product of the gasification process is syngas, which contains carbon monoxide, hydrogen and methane. Typically, the gas generated from gasification has a low heating value (LHV) of 3 – 6 MJ/Nm3.The other main product produced by gasification is a solid residue of non-combustible materials (ash) which contains a relatively low level of carbon.

Syngas can be used in a number of ways, including:

  • Syngas can be burned in a boiler to generate steam for power generation or industrial heating.
  • Syngas can be used as a fuel in a dedicated gas engine.
  • Syngas, after reforming, can be used in a gas turbine
  • Syngas can also be used as a chemical feedstock.

Gasification has been used worldwide on a commercial scale for several decades by the chemical, refining, fertilizer and electric power industries. MSW gasification plants are relatively small-scale, flexible to different inputs and modular development. The quantity of power produced per tonne of waste by gasification process is larger than when applying the incineration method.

The most important reason for the growing popularity of gasification of municipal solid wastes has been the increasing technical, environmental and public dissatisfaction with the performance of conventional incinerators.

Plasma Gasification

Plasma gasification uses extremely high temperatures in an oxygen-starved environment to completely decompose input waste material into very simple molecules in a process similar to pyrolysis. The heat source is a plasma discharge torch, a device that produces a very high temperature plasma gas. It is carried out under oxygen-starved conditions and the main products are vitrified slag, syngas and molten metal.

plasma-gasification

Vitrified slag may be used as an aggregate in construction; the syngas may be used in energy recovery systems or as a chemical feedstock; and the molten metal may have a commercial value depending on quality and market availability. The technology has been in use for steel-making and is used to melt ash to meet limits on dioxin/furan content. There are several commercial-scale plants already in operation in Japan for treating MSW and auto shredder residue.

Advantages of MSW Gasification

There are numerous MSW gasification facilities operating or under construction around the world. Gasification of solid wastes has several advantages over traditional combustion processes for MSW treatment. It takes place in a low oxygen environment that limits the formation of dioxins and of large quantities of SOx and NOx. Furthermore, it requires just a fraction of the stoichiometric amount of oxygen necessary for combustion. As a result, the volume of process gas is low, requiring smaller and less expensive gas cleaning equipment.

The lower gas volume also means a higher partial pressure of contaminants in the off-gas, which favours more complete adsorption and particulate capture. Finally, gasification generates a fuel gas that can be integrated with combined cycle turbines, reciprocating engines and, potentially, with fuel cells that convert fuel energy to electricity more efficiently than conventional steam boilers.

Disadvantages of Gasification

The gas resulting from gasification of municipal wastes contains various tars, particulates, halogens, heavy metals and alkaline compounds depending on the fuel composition and the particular gasification process. This can result in agglomeration in the gasification vessel, which can lead to clogging of fluidised beds and increased tar formation. In general, no slagging occurs with fuels having ash content below 5%. MSW has a relatively high ash content of 10-12%.

Role of Gas Turbines in Power Plant Reliability

Gas turbines play a huge role in power plant reliability. In most cases—whether it be simple-cycle or combined-cycle applications for gas turbines—the gas turbine is the first major piece of equipment in the process that needs to start. So, without a reliable control system or a well-maintained and cared-for control system, your primary piece of major equipment is out of the game or unavailable.

GE_H_series_Gas_Turbine

In this article, we will explain the role of gas turbines a little more, and why they so important for the reliability of your power plant.

Start Permissives: Ready to Start or Not?

Typically, when most frames 7FA, 6FA, 5A, or any industrial frame size gas turbine owner starts the plant with the gas turbine control system, there is typically a page with start permissives, indicating the system is ready to start or not ready to start. Start permissives are conditions on the unit that need to be met before it can start.

In many cases, the rest of the equipment at the plant depends on the gas turbine control system because it is often the first thing that plant managers will start before the other equipment. 

Therefore, if you receive the “not ready to start” indication, then you won’t be able to start your gas turbine—or the rest of your plant at all, especially if there are other drivers behind the gas turbine. 

How the Control System Works

A control system is made up of a bunch of subsystems, pretty much like everything in a power plant. So, the control system as a whole has subsystems under it, and that can kind of be broken down and analyzed in an engineering mind state. 

The primary parts of the control system are the software and logic, which are really reliable. They don’t typically break; they are just computer code that is programmed.

Typically when we see problems, malfunctions, abnormalities in logic or software, it’s because of some type of human interaction. Most control systems or any other equipment for that matter don’t fail on their own. Of course, failures without human interaction can happen, but they are rare.  

The relays in the system that bring the logic from the software are typically control cards and other communication devices. These devices can fail. In these cases, when the devices can fail, the logic and software fails as well.

Why Reliability is So Important

If you don’t have a reliable gas turbine control system, then you usually can’t even get the plane off the ground, so to speak. You can’t even really gain any momentum!

Therefore, it is important to perform check out and regular inspections of your control system equipment. To put it simply, it involves a clean and inspect of the system to check the control system, clean it out, perform some file management, and ensure that there aren’t any warning lights and that everything looks healthy and functional.

5 Points to Consider Before Switching Electric Suppliers

There are several reasons why homeowners want to switch electric suppliers. Some might feel like they’re paying more for their electricity, and they want to find something that will cost them less. Others might be moving to a new home or looking for renewable energy alternatives and more reliable service.

Whatever the reason may be, homeowners are now more able to explore and acquire the energy plan that suits their needs and resources. They can change their electricity providers anytime they want. But with numerous options in the market, it can be easy to feel lost and make a snap decision.

Before you get thrilled about cheaper energy tariffs and better customer service, here are essential points to consider before switching electric suppliers. It may save you a load of potential hassle and stress, especially if it’s your first time to do so.

electric-suppliers

1. Determine Your Needs and Preference

The first thing that you should think about when changing your electric supplier is your needs and preference. This way, you’d be able to point out specific reasons why your current provider is not right for you anymore.

You can ask yourself a few questions to sort what you need and prefer so you can come up with a more informed decision. Does your bill vary from month to month, or are you searching for a plan that your budget can comfortably afford more? Do you want to reduce your carbon footprint, or are you looking for better customer support?

Once you’ve identified the things you need and want that you didn’t get from your current supplier, it would be easier for you to choose a much better one. Take your time to ponder about them before you rush into the market.

2. Check Your Current Electric Bills

It’s also significant to look at your current electric bills, especially if your concern is a high and fluctuating statement every month. Before you review other supplier’s prices, it would be helpful to examine a recent electric bill from your current supplier. Evaluate how much you’ve been paying for your electricity.

By checking the costs that constitute your monthly electric bill, you’d be able to know whether the problem is on the consumption or with the rate. It would also prepare you to choose a new electric supplier that will surely meet your needs.

3. Research Your Options

Of course, doing some research before changing suppliers is essential. You can start an electric consumption comparison on Eligo Energy. When you do so, it will help best in finding better electric rates. When researching your options, you can break down the factors you want to look for in your new electric supplier.

Here are a few things you may not want to miss out on:

a. Price and Plan

Rates may vary in every supplier, and they are often linked to the unpredictable energy market. You must consider what kind of supply rate would work best for your home’s monthly budget before shopping for any electricity plans.

Opting for a fixed-rate plan might be a good idea if your concern is about fluctuations. But if you use most of your energy at night, you can look for a company that offers time-of-use plans. Note that each project comes with a cost, so it mostly depends on how much you’re willing to pay.

b. Products and Services

Suppliers provide many different types of products and services. It’s a must to check out what each company offers to assess better which one would best serve your needs.

Some companies use renewable energy resources, while others do not. If it’s something important to you, you can cross out from your options to those who don’t offer it.

c. Reputation

Many suppliers are using marketing tactics to capture your attention. Don’t get tempted by cheap rates that have hidden fees in the end. Be sure to switch to a company that has an established reputation. Check on their background before you sign up by looking at the reviews of previous customers.

4. Compare Offers

When looking for the best deal, you would have to compare offers from different providers. If you want to find out how much you could save, compare their electricity rates. However, consider all the other factors as well. Bear in mind that the lowest price isn’t always the best deal.

5. Review Your Current Contract

It is a must to review your contract with your current supplier. Take a look at the terms if there are charges if you leave your contract early. Make sure to ponder whether it would be worthwhile to change your electricity provider right away if there are any exit fees. You won’t have to worry about it, though, if you have an open contract.

Takeaway

It’s so tempting to dive into any electric supplier with cheaper rates and better offers than your current one. But doing so may cause you tons of money and regrets in the end. You would not want to experience the same frustration again. Therefore, take the time to research and weigh all your options before you sign up for anything.

5 Energy-Saving Measures for Homeowners

There are many easy ways to save money and electricity every month around your home. And as you will see from the following examples, they don’t all require you to downgrade your lifestyle or make major sacrifices in your everyday life. Some of these energy-saving measures will apply more during hot times of the year or cold times, but most will serve you well all year long.

save energy concept

And keep in mind that many of these energy-saving tips can apply just as well to businesses trying to save money as they do to homeowners.

1. Use Energy-Efficient Appliances

Your major household appliances use up a lot of electricity year-round, so when it comes time to repair or replace one of them, consider upgrading to a more energy-efficient model. Many manufacturers make refrigerators, dishwashers, ranges, washing machines and dryers that meet or exceed EnergyStar guidelines and can save you hundreds of dollars per year in lower energy bills.

2. Eliminate Electricity “Leaks”

Most homeowners are aware of water leaks in their homes such as leaky faucets, cracked garden hoses and poorly sealed pipe fittings in the walls. But your home could also be leaking electricity every day.

A lot of electricity gets wasted needlessly due to so-called “energy leaks”. These could include appliances that draw power 24/7, even when not in use. Other energy leaks could be simple things like leaving the lights turned on in empty rooms or falling asleep with the television on.

Fortunately, there are easy ways to reduce energy leaks without putting a drain on your lifestyle, such as using power strips, timers and motion sensors to cut off these devices when nobody is using them.

3. Improve Your Home’s Insulation

Another factor that drives up your monthly electric bill is the hot or cold air outside making its way into your home. There are two main ways to address this:

  1. Seal your doors and windows
  2. Put in better insulation

If your doors or windows are old and have cracks or holes, then go ahead and get those replaced. Double-paned glass windows and sliding doors can add an extra layer of protection to regulate your internal temperature.

home-insulation

If there are any gaps around the perimeter or frame of your doors and windows, then replacing the weatherstripping should seal those off easily. This is actually good DIY project for beginners that will only cost you a few bucks and a few minutes per door/window.

Replacing your insulation can be a big job and will likely require some professional help, not only to get the job done right, but also to ensure compliance with all building codes and regulations. The main question for you to discuss with your chosen contractor will be to decide what type of insulation will work best for your needs and your budget. Common materials include natural fibers, plastics, foam, minerals and fiberglass insulation.

When hiring a contractor, be sure they include air-sealing services in the estimate, since leaks, gaps and cracks in the walls, ceilings and floors should be done prior to putting in the insulation. Some insulation types, such as fiberglass insulation, are installed using techniques that literally blow the materials into place and do an excellent job of sealing off leaks.

4. Properly Use and Maintain Your HVAC System

Your heating, ventilation and cooling (HVAC) system can also make or break your power bill every month, especially during the winter or summer seasons. These heating and cooling systems are comprised of many motors and moving parts which are subject to wear and tear and will require ongoing maintenance.

While your HVAC system is designed to last for several years, some individual components can become worn out and create inefficiencies which overload the entire system, wasting energy and causing additional damage. So you do need to be diligent in maintaining or repairing these systems as needed. Many HVAC repair companies in your area offer free inspections of heaters, air conditioners and centralized ventilation systems, so take advantage of those when they are available.

5. Use Green Building Materials

When constructing a new home or adding on to your existing property, using green building materials can also help you save money on construction costs. Here are some examples of commonly-used green building materials:

  • Recycled steel and wood
  • Reclaimed doors, windows and lumber
  • Plant-based polyurethane foam
  • Bamboo
  • Wool

While you might not see much difference on your own personal utility bill, using building supplies made from recycled or reclaimed materials can save money on construction costs. And you can also save a lot of energy and resources on a larger scale – at the community level and eventually global level. Plus, many reclaimed material just a nice aesthetic to your home.

Saving energy at home can be easy, and with a little creativity and investment you don’t necessarily have to make any radical changes to your lifestyle either. Pick one or two of these energy-saving tips for homeowners and put them to use today.

The Impact of Machine Learning on Renewable Energy

Machine learning, as well as its endgame, artificial intelligence, is proving its value in a wide variety of industries. Renewable energy is yet another sector that can benefit from machine learning’s smart data analysis, pattern recognition and other abilities. Here’s a look at why the two are a perfect match.

Predicting and Fine-Tuning Energy Production

One of the biggest misconceptions about solar power is that it’s only realistic in parts of the world known for year-round heat and intense sunshine. According to Google, around 80% of rooftops they’ve analyzed through their Sunroof mapping system “are technically viable for solar.” They define “viable” as having “enough unshaded area for solar panels.”

Even with this widespread viability, it’s useful to be able to predict and model the energy yield of a renewable energy project before work begins. This is where machine learning enters the equation.

Based on the season and time of day, machine learning can produce realistic and useful predictions for when a residence or building will be able to generate power and when it will have to draw power from the grid. This may prove even more useful over time as a budgeting tool as accuracy improves further. IBM says their forecasting system, powered by deep learning, can predict solar and wind yield up to 30 days in advance.

Machine learning also helps in the creation of solar installations with physical tracking systems, which intelligently follow the sun and angle the solar panels in order to maximize the amount of power they generate throughout the day.

Balancing the Smart Energy Grid

Predicting production is the first step in realizing other advantages of machine learning in clean energy. Next comes the construction of smart grids. A smart grid is a power delivery network that:

  • Is fully automated and requires little human intervention over time
  • Monitors the energy generation of every node and the flow of power to each client
  • Provides two-way energy and data mobility between energy producers and clients

A smart grid isn’t a “nice to have” — it’s necessary. The “traditional” approach to building energy grids doesn’t take into account the diversification of modern energy generation sources, including geothermal, wind, solar and hydroelectric. Tomorrow’s electric grid will feature thousands and millions of individual energy-generating nodes like solar-equipped homes and buildings. It will also, at least for a while, contain coal and natural gas power plants and homes powered by heating oil.

Machine learning provides an “intelligence” to sit at the heart of this diversified energy grid to balance supply and demand. In a smart grid, each energy producer and client is a node in the network, and each one produces a wealth of data that can help the entire system work together more harmoniously.

Together with energy yield predictions, machine learning can determine:

  • Where energy is needed most and where it is not
  • Where supply is booming and where it’s likely to fall short
  • Where blackouts are happening and where they are likely
  • When to supplement supplies by activating additional energy-generating infrastructure

Putting machine learning in the mix can also yield insights and actionable takeaways based on a client’s energy usage. Advanced metering tools help pinpoint which processes or appliances are drawing more power than they should. This helps energy clients make equipment upgrades and other changes to improve their own energy efficiency and further balance demand across the grid.

Automating Commercial and Residential Systems

The ability to re-balance the energy grid and respond more quickly to blackouts cannot be undersold. But machine learning is an ideal companion to renewable energy on the individual level as well. Machine learning is the underlying technology behind smart thermostats and automated climate control and lighting systems.

Achieving a sustainable future means we have to electrify everything and cut the fossil fuels cord once and for all. Electrifying everything means we need to make renewable energy products more accessible. More accessible renewable energy products means we need to make commercial and residential locations more energy-efficient than ever.

Machine learning gives us thermostats, lighting, and other products that learn from user preferences and patterns and fine-tune their own operation automatically. Smart home and automation products like these might seem like gimmicks at first, but they’re actually an incredibly important part of our renewable future. They help ensure we’re not burning through our generated power, renewable or otherwise, when we don’t need to be.

Bottom Line

To summarize all this, machine learning offers a way to analyze and draw actionable conclusions from energy sector data. It brings other gifts, too. Inspections powered by machine learning are substantially more accurate than inspections performed by hand, which is critical for timely maintenance and avoiding downtime at power-generating facilities.

Machine learning also helps us predict and identify factors that could result in blackouts and respond more quickly (and with pinpoint accuracy) to storm damage.

Given that the demand for energy is only expected to rise across the globe in the coming years, now is an ideal time to use every tool at our disposal to make our energy grids more resilient, productive and cost-effective. Machine learning provides the means to do it.

Everything You Should Know About Electricity

Electricity, we use it every day but what is it? The dictionary defines it as a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current. This may sound confusing, but by breaking it down we can understand how it works. Electricity is used for many everyday things but breakthroughs of how to use it have resulted in many cool inventions, some of which you can explore on thehomesecuritysuperstore.

A Closer Look at Atoms

So, what is electricity? To understand how electricity works we have to break it down, starting with the charged particles. Everything is made of atoms, and these atoms are mostly empty space. Moving around in the empty space are electrons and protons. These each carry an electric charge, electrons being negative and protons being positive. These opposite charges attract each other. The atom is in balance when there are an equal number of protons and electrons. The number of protons determines what kind of element the atom is, and these numbers and elements are shown on the periodic table.

Imagine the atom as having rings around the nucleus, the center of the atom. These rings can hold a certain number of electrons which move constantly around the nucleus which holds the protons. When the rings hold electrons that are attracted to the protons the strength of this attraction can push an electron out of its orbit and even make them shift from one atom to another. This is where electricity occurs.

Traveling in Circuits

Now that we know the basics of electricity, we can look at how it works. For a basic understanding of how electricity travels through circuits and how we use electricity we will look at batteries and light bulbs. Batteries can produce electricity through a chemical substance called an electrolyte.

The battery is attached to two metals, one on either end, and produces a negative charge in one metal and a positive charge in the other metal. When the battery is then connected on either end by a conductor such as a wire the electrical charge is balanced. If you were to attach a light bulb to the wire in between the sides of the battery, the electrical current would then travel through the light bulb to get to the other side of the battery and thus powering the light.

LED-lighting-workplace

Electricity moves through electrical circuits and must have a complete path for the electrons to move through. The switch or power button on electronic devices opens and closes this path. When you turn on the light switch the circuit is closed and electrons can move freely to turn on your lights. When you turn off the switch it opens the circuit not allowing the electrons through and turning off your lights. When light bulbs burn out the small wire connecting the circuit inside the light bulb breaks and stops the flow of electrons.

Final Thoughts

Energy flows through our entire world and understanding how electricity works is just the beginning. Of course, most of the electricity in your life is not connected to a single battery as in the example above, but the understanding on a basic level is very interesting.

Electricity literally powers everything in our lives and a world without it would be very different. Understanding how these things work lets us enrich our knowledge of the world around us and provides us with practical information we can use in our everyday life. Electricity is all around us and is used in more interesting ways than just light bulbs and batteries.

How to Become More Energy-Efficient at Work?

Nowadays, smart business owners are taking steps towards making their company more efficient in every way. By establishing more efficient processes, these businesses are capable of getting more done in a shorter amount of time, and they’re also saving money along the way. But, beyond helping their employees perform better, business pros are also working on implementing tools and strategies for becoming increasingly more energy efficient so that their business can be greener and so that they can save money on their energy bill.

save energy concept

If you are ready to take your basic eco-friendly office to the next level, keep reading for some helpful information on how to become more energy efficient at work.

1. Make the Switch to Laptops

Desktop computers that are always plugged in are always consuming some level of energy, even when they are turned off. Unless you have all of your electronics plugged into a power strip that is turned off at the end of every workday, those devices will continue draining energy, and you will see it on your energy bill. For this reason, a lot of businesses are opting to make the switch to using laptops rather than desktops.

Laptops only need to be plugged in when they are in need of a charge; the rest of the time, they use a built-in battery to function. This can help you save quite a bit of money on your energy bill, and it can also help you save much-needed space because laptops are smaller than desktop computers with separate monitors. This is one of the easiest ways to make your office more energy efficient, and your employees will likely welcome the change to laptops as well.

2. Purchase Products Having Energy Star Seal

Another way to save money on your energy bill while making your office more energy efficient is by switching to Energy Star appliances and office products that will use up far less energy than their counterparts. Properly dispose of old appliances, such as your office’s refrigerator and microwave, and replace them with Energy Star appliances so that you can start to save money and allocate it towards more important aspects of your day-to-day operations.

Beyond appliances, office products like printers, scanners, copiers, and computers can also come with the Energy Star seal, so be sure to stick with those as well. Because you use these products every day, and for hours on end, making the switch to energy efficient office equipment is wise.

3. Get Smart About Lighting

Another way to become more energy efficient at work is by focusing on the lighting throughout your office. It is important to replace outdated light bulbs that are less efficient than modern options. So, for example, you could replace incandescent light bulbs with LED bulbs, which do not contain the harmful mercury that compact fluorescent light bulbs contain. Beyond that, you can check to see if there are any light fixtures that you do not really need to have in place after all. Plus, simply turning the lights off when you leave a room can be a great way to save money really easily.

LED-lighting-workplace

You can even opt to install light fixtures that use sensors to determine when there are people in a room, thereby allowing the lights to turn on and off automatically. And, finally, whenever possible, take advantage of natural light during the day so that you can rely less upon artificial, energy-consuming light.

4. Keep Your Staff Comfortable, but Save Money Too

What temperature is your office thermostat currently set to? Do you think that you can maybe tweak the temperature a bit so that you could save money, while also keeping everyone comfortable? Many times, office thermostats are set at temperatures that end up costing the business a lot of money. Small changes in temperature can make a big difference in your energy savings, but your staff are not likely to notice the changes because they will still feel comfortable while they work.

To keep the workers productivity high enough, you should definitely keep your office warm with the minimum cost incurred. It is more reasonable to use the energy efficient radiators that enable you to control the heating easily from anywhere you want. For instance, you can use BestElectricRadiators to not spend much money and keep the heating as well as the productivity of the workers.

eco-friendly-business-practices

For example, you can save money during the summer by setting the thermostat to 78-80°F. When the workday is over, you can allow the office to reach 80°F because no one will be there anyway, so you don’t need to bother keeping the air conditioner going. In the winter, on the other hand, you can keep your thermostat set anywhere from 65-68°F, and you can let it drop to 60°F overnight when no one is in the office. Go ahead and change the temperature setting by a degree or two for a month to see how much you can save.

Conclusion

It is pretty clear to see that it is very important to become more energy-efficient at work. The first step involves setting up an eco-friendly office. But, once you have set the foundation, you can go even further by becoming energy efficient for the planet and for your bottom line.

The Issues and Impact of Energy Storage Technology

Renewable energy has taken off. Wind and solar in particular had grown rapidly, since they can be installed on a small scale and connected to the grid. This has created a number of problems for utility companies while failing to deliver the promised benefits because energy storage technology has not caught up. Let’s look at some of the issues with renewable energy before explaining how advances in energy storage technology will ease these concerns.

The Instability of the Power Grid

The rapid growth of renewable power has added to the instability of the power grid. First, the introduction of many variable power sources forces utilities to deal with varying power supply relative to demand. Second, the relative lack of energy storage systems means there is far more wasted energy than before. When there is a spike in solar or wind power, they can’t store most of it for future usage. This adds to the instability and risk of failure of local portions of the power grid.

If we had more widespread, efficient energy storage, energy producers could save power above the expected power created locally instead of leaving power companies to turn on and off natural gas turbines to meet variation in demand. It would also eliminate the need to build natural gas turbines as backup power sources for when new renewable power sources aren’t meeting expectations.

The Lack of Backup Power

Solar power has long been a source of power for off-the-grid properties. However, this is dependent on having energy storage on site, typically batteries. Yet many solar roofs were set up to minimize cause and maximize tax credits to the detriment of home owners. We can look at the multiple disasters that hit California along with their wildfires. Utility companies couldn’t raise rates to pay for more fire-resistant infrastructure. They could be sued for any new wildfires blamed on the power equipment. The utility company’s only solution as to turn off power to areas that were burning or at risk of catching fire, if they didn’t want to be shut down entirely.

California has one of the highest rates of solar roof installations in the world. Unfortunately, most of those solar roofs were connected directly to the power grid, and the home owner receives power from the grid. This minimized how much equipment had to be installed while giving them the ability to sell power to the grid and get power from the grid. The problem is that they couldn’t get power from the grid when the power grid was shut down unless they paid several thousand dollars extra for renewable energy storage; note that less than two percent of customers did this. That hurt the broader power grid, as well, since solar roofs couldn’t deliver power to the power grid when the power grid was shut down.

The greatest irony was suffered by electric car owners. Imagine being told that you need to flee the wildfires, and all you have is an electric car that you can’t charge. A few homeowners made matters worse by tapping into their Tesla car battery to try to power their homes for a while, draining it dry.

Yet those few people with battery storage systems were fine. Their homes were wired in such a way that they could pull from the battery power when the power grid was down, assuming they were ever connected to the grid. They could continue to run their air conditioners and other appliances though no one else had power. For those that had solar roofs connected to the grid and energy storage systems, the grid being down means all of their power went into the battery. That energy wasn’t wasted, and the family could use it.

Biomass Cogeneration Systems

Biomass fuels are typically used most efficiently and beneficially when generating both power and heat through biomass cogeneration systems (also known as combined heat and power or CHP system). Biomass conversion technologies transform a variety of wastes into heat, electricity and biofuels by employing a host of strategies. Conversion routes are generally thermochemical or biochemical, but may also include chemical and physical.

The simplest way is to burn the biomass in a furnace, exploiting the heat generated to produce steam in a boiler, which is then used to drive a steam turbine. Advanced biomass conversion technologies include biomass integrated gasification combined cycle (BIGCC) systems, cofiring (with coal or gas), pyrolysis and second generation biofuels.

Biomass Cogeneration Systems

A typical biomass cogeneration (or biomass cogen) system provides:

  • Distributed generation of electrical and/or mechanical power.
  • Waste-heat recovery for heating, cooling, or process applications.
  • Seamless system integration for a variety of technologies, thermal applications, and fuel types into existing building infrastructure.

Biomass cogeneration systems consist of a number of individual components—prime mover (heat engine), generator, heat recovery, and electrical interconnection—configured into an integrated whole. The type of equipment that drives the overall system (i.e., the prime mover) typically identifies the CHP unit.

Prime Movers

Prime movers for biomass cogeneration units include reciprocating engines, combustion or gas turbines, steam turbines, microturbines, and fuel cells. These prime movers are capable of burning a variety of fuels, including natural gas, coal, oil, and alternative fuels to produce shaft power or mechanical energy.

Key Components

A biomass-fueled cogeneration facility is an integrated power system comprised of three major components:

  • Biomass receiving and feedstock preparation.
  • Energy conversion – Conversion of the biomass into steam for direct combustion systems or into biogas for the gasification systems.
  • Power and heat production – Conversion of the steam or syngas or biogas into electric power and process steam or hot water

Feedstock for Biomass Cogeneration Plants

The lowest cost forms of biomass for cogeneration plants are residues. Residues are the organic byproducts of food, fiber, and forest production, such as sawdust, rice husks, wheat straw, corn stalks, and sugarcane bagasse. Forest residues and wood wastes represent a large potential resource for energy production and include forest residues, forest thinnings, and primary mill residues.

Energy crops are perennial grasses and trees grown through traditional agricultural practices that are produced primarily to be used as feedstocks for energy generation, e.g. hybrid poplars, hybrid willows, and switchgrass. Animal manure can be digested anaerobically to produce biogas in large agricultural farms and dairies.

To turn a biomass resource into productive heat and/or electricity requires a number of steps and considerations, most notably evaluating the availability of suitable biomass resources; determining the economics of collection, storage, and transportation; and evaluating available technology options for converting biomass into useful heat or electricity.
