Conserving Energy and Going Green Class 3 Fall 09 GCCC Encore Program Joe Boisvert, Encore Instructor
Problems with Coal for Electricity (Coal Ash) <ul><li>Over 1 billion gallons of toxic coal ash sludge burst through the dam of a waste pond, located 60 feet above the Emory River at TVA’s Kingston Fossil Plant in Harriman, Tennessee. The waste covered 300 acres below the plant, destroying homes, poisoning rivers and contaminating coves and residential areas. </li></ul>
In yet another controversial development in the case of he Tennessee coal ash spill , the millions of pounds of ash are being shipped from the accident site to a landfill in a poor county in Alabama.
Where is Your Clean Coal Now? <ul><li>We all know that burning coal is a very dirty source of energy . Just the act of mining it out of the ground causes a fair amount of destruction (and costs the lives of many miners, especially in poorer countries), and burning it produces more CO2 than any other source of energy , as well as mercury that makes its way up the food chain and smog-forming emissions of all kinds... But that's not all! Even after all that you are left with literally tons of coal ash (fly ash captured from the chimneys, and bottom ash from the furnace) </li></ul>
Bamboo Flooring 1 - Top Ten Benefits <ul><li>Renewable resource. Easy upkeep. While no flooring surface is completely maintenance free, some are better than others </li></ul><ul><li>Easy to install. While there are several ways to install bamboo flooring, one popular option is the beloved "floating floor," </li></ul><ul><li>Cost. The cost of bamboo flooring can vary greatly, Another cost-saver is the option of self-installation. That particular cost saving can be tremendous, depending on the application. Style points. Style counts, and when it comes to bamboo floors, style is what it’s about. From its mellow light hues and colors, to its widely varying grains, bamboo can match almost any décor </li></ul>
Advantages of Bamboo Floors <ul><li>Adaptability. Bamboo is one of the most adaptable flooring options available today. Material Handling. For some hardwood materials, like mahogany or oak, handling and cutting can prove to be a chore in itself. This isn’t the case for bamboo; general hand tools, cross cut saws, compound miter saws and dovetail saws are perfect for finishing a home project like this. </li></ul><ul><li>Strength. In Japan, bamboo has historically been used for industrial scaffolding, </li></ul><ul><li>Durability. People instantly think of tile or marble when they are looking for a durable flooring surface, but bamboo can certainly be considered a top contender for longest lasting. Material Availability. Since its increase in recent popularity, bamboo has gone from a difficult to find and somewhat obscure material, to a widely available surface found at almost any home improvement center. </li></ul>
Energy Savings - Is Your Computer Deleting What's In Your Wallet? <ul><li>The computer is a vital source for information, business and personal relationships </li></ul><ul><li>In an effort to have their computer at-the-ready whenever it’s needed, many, if not most computer users leave their computers constantly running. </li></ul><ul><li>This type of computing habit can end up costing you more than you realize on your electric bill. </li></ul>
Understanding Your Computer’s Power Management <ul><li>For PC owners, modern versions of the Microsoft operating systems provide easy to manage power settings. With modes like idle, stand-by and sleep, setting up an energy profile is easy. But first let’s look at the difference between energy modes. </li></ul><ul><li>Idle – This is when the computer is left powered on but with no programs other than the operating system running. </li></ul><ul><li>Stand-By – This places your computer in a hibernation mode. You will have to press your computer’s power button to bring the computer back up. When in stand-by, the computer is as close to being actually off as it can be. It only uses about 2 watts of power while in stand-by. </li></ul><ul><li>Sleep – This condition has your hard drives and your monitor turned off but a simple move of the mouse brings everything awake again. </li></ul>
The new Windows Vista operating system features three pre-set power plans. They include <ul><li>Balanced, </li></ul><ul><li>Power Saver </li></ul><ul><li>High Performance. </li></ul><ul><li>If it’s a laptop you’re using, then the power scheme you choose will also affect your battery life as well. </li></ul>
Computer Monitors <ul><li>Another thing to consider when thinking about computer energy conservation, is to look into replacing your big, television-sized monitor with a flat screen model. Flat screen monitors are much more energy efficient and better looking than their boxy predecessors. </li></ul><ul><li>With utility costs rising at incredible rates, it makes complete financial sense to save energy where you have the ability to, and that includes configuring your computer’s power settings. </li></ul>
Conserving Your Computer’s Energy – Things Change <ul><li>Most computer manufacturers agree that you should set your power management profile on your computer to turn your monitor off after 10 minutes of non use. They also advise to configure your hard disks to turn off after 20 minutes of inactivity. </li></ul><ul><li>If you use a screensaver on your computer, you may think that your computer is using less energy, when in fact, the opposite may be true. When you see your screensaver on and you can still hear your computer humming like a locomotive, then you know you’re not saving energy! Set your power scheme to go from your screensaver to sleep mode after a certain period of time to help conserve energy. </li></ul>
It was once believed to be better for your computer if it was left on all the time. It was thought that turning it off every night and back on the next morning would wear out components and shorten the life of the computer. We now know that to be untrue. But what we also know is that by turning your computer and all of your peripherals off every night, you can save anywhere from 100 to 400 kWh per computer! If it doesn’t hurt your computer but it does save you money, why not do it?
PC Power Management Saves Money <ul><li>"Power management is probably one of the easiest, low-cost ways to get big, big savings, </li></ul><ul><li>" Kaplan says, pointing out that using power management features on desktop PCs can save $50 per computer per year. </li></ul><ul><li>Enabling power management tools on monitors can save another $12 to $90 annually per monitor. </li></ul>
Depending on what type of set you buy, a television can consume as little as 45 watts or as much as 500 watts, and cost anywhere from $13 to $145 per year to run.
Low Water Usage Toilets <ul><li>Lowe's wants to help you save water and money. By incorporating some easy fixes and adjustments to your home water use, you can potentially knock off a third of the cost of your annual water and sewer bill. </li></ul><ul><li>Lowe's is proud to offer products that bear the Water Sense® label. </li></ul>
Get Flush With Savings <ul><li>Replace your older toilet with a Water Sense-labeled high-efficiency model that uses 20% less water but doesn't sacrifice performance. A family of four can save more than $90 per year and more than $2000 in reduced water utility bills over the toilet’s lifetime when replacing older, existing toilets with Water Sense-labeled options. </li></ul>
Example of Water Savings <ul><li>Can save a family of four more than 16,000 gallons of water each year when replacing older, existing toilets. That’s enough water to: </li></ul><ul><li>Make more than 250,000 cups of coffee </li></ul><ul><li>Do more than 1,800 loads of dishes </li></ul><ul><li>Take more than 900 showers </li></ul><ul><li>Do more than 300 loads of laundry </li></ul><ul><li>Fill 2 backyard swimming pools </li></ul>
