The Top Ten Energy Efficiency Best Practices and Best Available Technologies Task Group (TOP TENs)
This indicator has also served to track improvements in energy efficiency and to see how the actions we have implemented have helped us to dramatically cut costs. There are two types of energy saving actions: those that do not require investment and those tha do. Both are very interesting and should be combined, but obviously, zero-cost actions are the most appealing. As an example of a zero-cost action, in companies without an energy efficiency policy much of their energy is wasted during periods of inactivity holidays, weekends or idle machines etc.
This is referred to as passive consumption. I recommend that this entire process be guided by specialists or partners in energy management. Finally, internal buy-in is crucial if you want to implement an energy efficiency system in your industrial facility. Regular cleaning and planned maintenance of your electrical and mechanical equipment will go a long way towards optimising its performance and lifespan, which can translate to energy efficiency savings. Performing regular maintenance on your equipment will prolong its lifespan. Air conditioning and heating.
Newer heating and cooling systems will be far more efficient than old ones, so it may be worth getting systems more than 10 years old replaced. Both blow heaters and portable radiators use significant amounts of electricity and will chew through the power bills so discourage their use. Lastly ensure your air conditioning and heating are set to the optimum points during the seasons. Reduce your energy consumption by ensuring your air conditioning is set at the right temperature. Insulation acts as a barrier against temperature shifts, making it much easier to keep the workplace warmer in winter and cooler in summer.

By installing insulation in the roof, and walls of your workspace, you can reduce the amount of energy needed to maintain room temperature during heat loss and heat gain. This is one of the most practical and cost effective ways to make your facility more energy efficient. Often, the primary source of heat entering a building is via unprotected windows. This will reduce the impact of those extreme Australian summer temperatures, improve comfort and save energy.
LED bulbs use about a quarter of the energy to produce the same light as halogens and can last five to ten times longer. This makes them the logical lighting choice for energy savings, particularly when manufacturing workspaces need adequate and plentiful lighting. Comparative illustration of LED bulb and incandescent bulb.
IoT Impact Inserted of two further decay coefficients in the Method to ensure proponents can calculate abatement in the event they decide to delay the start of their crediting period. Energy audits and energy management can be seen as important instruments to recognise and observe existing economic energy efficiciency potentials by systematic procedures to gain knowledge and developing a strategy to achieve energy efficiency targets. While several energy efficiency measures are already in place for small and medium enterprises SMEs , more tailored programmes are needed to address their special needs.

Opening a window, or building door is a simple energy saving technique that can help reduce air conditioning and heating costs by relying on natural ventilation for climate control. Especially as many places in Australia experience up to one hundred days per year with nice enough weather that you can open windows or a roller door. Make sure that pipe lagging on all refrigerant lines are intact as insulation is absolutely crucial , especially if the air conditioner is an outdoor unit. If the air conditioner lines are not insulated, it's just absorbing heat from the environment and cooling the outside air instead of the building and vice versa in winter.
Depending on the appliances used in the workplace, you can optimise their settings to increase energy savings. For example, you can increase the drinks fridge temperature in the kitchen by one or two degrees to save energy without impacting employees or business. Advanced boilers and furnaces can operate at higher temperatures while burning less fuel.
These technologies are more efficient and produce fewer pollutants. Over 45 percent of the fuel used by US manufacturers is burnt to make steam. The typical industrial facility can reduce this energy usage 20 percent according to the US Department of Energy by insulating steam and condensate return lines, stopping steam leakage, and maintaining steam traps. Electric motors usually run at a constant speed, but a variable speed drive allows the motor's energy output to match the required load.
This achieves energy savings ranging from 3 to 60 percent, depending on how the motor is used. Motor coils made of superconducting materials can also reduce energy losses. Industry uses a large number of pumps and compressors of all shapes and sizes and in a wide variety of applications. The efficiency of pumps and compressors depends on many factors but often improvements can be made by implementing better process control and better maintenance practices.
Compressors are commonly used to provide compressed air which is used for sand blasting, painting, and other power tools.
Improving energy efficiency for manufacturers
According to the US Department of Energy, optimizing compressed air systems by installing variable speed drives, along with preventive maintenance to detect and fix air leaks, can improve energy efficiency 20 to 50 percent. Using improved aerodynamics to minimize drag can increase vehicle fuel efficiency. Reducing vehicle weight can also improve fuel economy, which is why composite materials are widely used in car bodies. More advanced tires, with decreased tire to road friction and rolling resistance, can save gasoline. Fuel economy can be improved by up to 3.
The design of a car impacts the amount of gas needed to move it through air. Aerodynamics involves the air around the car, which can affect the efficiency of the energy expended. Turbochargers can increase fuel efficiency by allowing a smaller displacement engine.

The performance of the two-cylinder is not only equivalent to a 1. Energy-efficient vehicles may reach twice the fuel efficiency of the average automobile. Cutting-edge designs, such as the diesel Mercedes-Benz Bionic concept vehicle have achieved a fuel efficiency as high as 84 miles per US gallon 2.
The mainstream trend in automotive efficiency is the rise of electric vehicles all electric or hybrid electric. Electric engines have more than double the efficiency of internal combustion engines. Finally, all-electric cars are also growing in popularity; the Tesla Model S sedan is the only high-performance all-electric car currently on the market. Cities around the globe light up millions of streets with million lights.
Energy Efficiency Trends and Policies in Industry. 6. KEY MESSAGES. TRENDS. • Industrial energy consumption has remained roughly stable at EU level. This report proposes an evaluation of energy efficiency progress achieved in industry since at EU level. The analysis includes both a review of energy.
There are several ways to reduce energy usage in air transportation, from modifications to the planes themselves, to how air traffic is managed. As in cars, turbochargers are an effective way to reduce energy consumption; however, instead of allowing for the use of a smaller-displacement engine, turbochargers in jet turbines operate by compressing the thinner air at higher altitudes. This allows the engine to operate as if it were at sea-level pressures while taking advantage of the reduced drag on the aircraft at higher altitudes. Air traffic management systems are another way to increase the efficiency of not just the aircraft but the airline industry as a whole.
New technology allows for superior automation of takeoff, landing, and collision avoidance, as well as within airports, from simple things like HVAC and lighting to more complex tasks such as security and scanning. Alternative fuels, known as non-conventional or advanced fuels , are any materials or substances that can be used as fuels , other than conventional fuels. Some well known alternative fuels include biodiesel , bioalcohol methanol , ethanol , butanol , chemically stored electricity batteries and fuel cells , hydrogen , non-fossil methane , non-fossil natural gas , vegetable oil , and other biomass sources.
The production efficiency of these fuels greatly differs. Energy conservation is broader than energy efficiency in including active efforts to decrease energy consumption, for example through behaviour change , in addition to using energy more efficiently. Examples of conservation without efficiency improvements are heating a room less in winter, using the car less, air-drying your clothes instead of using the dryer, or enabling energy saving modes on a computer. As with other definitions, the boundary between efficient energy use and energy conservation can be fuzzy, but both are important in environmental and economic terms.

Many energy intermediary organisations, for example governmental or non-governmental organisations on local, regional, or national level, are working on often publicly funded programmes or projects to meet this challenge. The National Renewable Energy Laboratory maintains a comprehensive list of apps useful for energy efficiency. Commercial property managers that plan and manage energy efficiency projects generally use a software platform to perform energy audits and to collaborate with contractors to understand their full range of options.

Both strategies must be developed concurrently in order to stabilize and reduce carbon dioxide emissions. Efficient energy use is essential to slowing the energy demand growth so that rising clean energy supplies can make deep cuts in fossil fuel use. If energy use grows too rapidly, renewable energy development will chase a receding target. Likewise, unless clean energy supplies come online rapidly, slowing demand growth will only begin to reduce total carbon emissions; a reduction in the carbon content of energy sources is also needed.
A sustainable energy economy thus requires major commitments to both efficiency and renewables. If the demand for energy services remains constant, improving energy efficiency will reduce energy consumption and carbon emissions. However, many efficiency improvements do not reduce energy consumption by the amount predicted by simple engineering models. This is because they make energy services cheaper, and so consumption of those services increases. For example, since fuel efficient vehicles make travel cheaper, consumers may choose to drive farther, thereby offsetting some of the potential energy savings.
Similarly, an extensive historical analysis of technological efficiency improvements has conclusively shown that energy efficiency improvements were almost always outpaced by economic growth, resulting in a net increase in resource use and associated pollution. The rebound effect may be particularly large for lighting, because in contrast to tasks like transport there is effectively no upper limit on how much light could be considered useful.
