Energy efficient choices can save families about a third on their energy bill with similar savings of greenhouse gas emissions, without sacrificing features, style or comfort. ENERGY STAR helps you make the energy efficient choice.If looking for new household products, look for ones that have earned the ENERGY STAR. They meet strict energy efficiency guidelines set by the Environmental Protection Agency EPA and US Department of Energy.If looking for a new home, look for one that has earned the ENERGY STAR.If looking to make larger improvements to your home, Environmental Protection Agency (EPA) offers tools and resources to help you plan and undertake projects to reduce your energy bills and improve home comfort.

Energy Efficiency PurposeThe purpose of energy efficient appliances and motors

is to be able to supply the same level of energy service only using less energy.

Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior.

Energy conservation reduces the energy consumption and energy demand per capita and thus offsets some of the growth in energy supply needed to keep up with population growth

Making a DifferenceAlong with saving money, energy efficient appliances

and motors save the plantThe energy used to run a product can be cut up to

80%There is a large potential to make a difference

because all appliances energy usage can be cutFridges, washers, dryers, carsLight bulbs, anything that plugs

Into an outlet.

Buy energy efficientIt may seem like there's little you can do to cut the amount of electricity you use – after all, few of us could function without a fridge or washing machine, and that Sunday roast won't cook itself.But choosing more energy-efficient appliances can cut your electricity bills. Most white goods and common kitchen appliances have an energy-efficiency rating (A to G), through a scheme organized by the European Union(EU). For cold appliances such as fridge-freezers look for A++ or A+ ratings.

Moving toward Energy-Efficient Appliances

Energy Star is an international standard for energy efficient consumer products originated in the United States of America. It was first created as a United States government program during the early 1990s, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program. Devices carrying the Energy Star logo, such as computer products, kitchen appliances, buildings and other products, generally use 20%–30% less energy than required by federal standards. However, many European-targeted products are labeled using a different standard, TCO Certification, a combined energy usage and rating from the Swedish Confederation of Professional Employees (TCO) instead of Energy Star

If you are looking to buy new energy efficient appliances for your kitchen, there are a couple of ways to make sure that you are getting a good deal in terms of energy saving. All appliances are now rated using the EU Energy label so it is easy to spot energy efficient appliances. In addition the Energy Saving Recommended logo from the Energy Saving Trust is applied to certain products.

Compact Fluorescent Lamp

A compact fluorescent lamp (CFL; also called compact fluorescent light, energy-saving light, and compact fluorescent tube) is a Fluorescent Lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.

Page 11: Energy efficient appliances

Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use less power (typically one fifth) and have a longer rated life (six to ten times average). In most countries, a CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.

LED Lighting LEDs (Light Emitting Diodes) are solid light bulbs which are extremely energy-efficient. When first developed, LEDs were limited to single-bulb use in applications such as instrument panels, electr-

onics, pen lights and, more recently, strings of indoor and outdoor Christmas lights . Manufacturers have expanded the application of LEDs by "clustering" the small bulbs. The first clustered bulbs were used for battery powered items such as flashlights and headlamps. Today, LED bulbs are made using as many as 180 bulbs per cluster, and encased in diffuser lenses which spread the light in wider beams. Now available with standard bases which fit common household light fixtures, LEDs are the next generation in home lighting.

Solar water heating

Solar water heating (SWH) or solar hot water (SHW) systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. SWH has been widely used in Greece, Turkey, Israel, Australia, Japan, Austria and China. In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof.

Page 16: Energy efficient appliances

No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground or floor mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors. SWH systems are designed to deliver hot water for most of the year.

However, in winter there sometimes may not be sufficient solar heat gain to deliver sufficient hot water. In this case a gas or electric booster is normally used to heat the water.

Electronic Fan RegulatorElectronic Fan Regulator that is extensively used to regulate and control the speed of the fans. Electronic fan regulator is an electronic device consisting of diacs, triacs, potentiome-tric resistance to provide stepless control of fan speed. This is an energy saving deviceand has advantages over the conventionaltype of fan regulators having more energy losses. These regulators can also be used as a speed regulator for many other small F.H.P. motors used in mixer, laboratory solution mixer etc, with appropriate current ratings.

Advantages of Energy-Efficient EquipmentMore than half the electricity used to power computer sis wasted. EPA estimates that a 1,000 computer office could typically save 200,000 kWh by enabling monitor power management features – That’s about $20,000 a year or emissions from 27 cars. Turning computers off at night can double savings to 400,000 kWh.

LeadershipWhen you specify ENERGY STAR equipment, you are following the lead of State government’s . Governor Pataki’s Executive Order 111 (Green and Clean State

Buildings and Vehicles) sets specific goals for saving energy and requires that State entities purchase ENERGY STAR equipment. Several progressive New York State jurisdictions, like Erie County, are adopting energy efficiency mandates. You can continue this trend and be recognized as a leader by your constituents.

Page 19: Energy efficient appliances

Cost SavingsBy using ENERGY STAR office equipment, your utility bills will be significantly reduced and maintenance costs will be lower. For example, ENERGY STAR computers typically use half the electricity ofstandard computers if they are enabled and turned off at night. And, there is often no purchase premiumwhen buying these products. ENERGY STAR products allow you to reallocate taxpayer dollars to meetthe needs that your constituents value most, for little or no capital investment.

Environmental ResponsibilityBecause it uses less energy, ENERGY STAR equipment produces less greenhouse gas emissions, resulting in a cleaner, healthier environment. In addition, ENERGY STAR products save natural resources (coal, oil and natural gas). The U.S. EPA estimates that the energy saved over the life of 50 high-volume ENERGY STAR copiers is equivalent to removing the annual emissions of 40 cars from the highway.

Ease of PurchasingMost New York counties already buy office products using New York State Office of General Services (NYOGS) contracts, which require ENERGY STAR compliance. NYOGS contracts satisfy New York State’s competitive bidding requirements.
