Gurdeep Singh What is Energy Efficiency and Management? Achieving Efficiency Places of application Case study Battery power EE means a reduction in energy consumption for the same service or activity increased/enhanced services for a given amount of energy inputs or Energy efficiency is associated with economic efficiency and includes technological, behavioural and economic changes. EE indicators estimates energy-consumption trends for a controlled set of energy services (the market basket). This method of indexing is a type of "bottom-up" approach. Market-Basket Approach This approach can be thought of as a "top-down" approach. It is like peeling away all the effects until energy efficiency is all that remains. Comprehensive Approach According to this approach, the difference between the current or average practice of producing e.g. a ton of steel and the "best practice" of producing e.g. a ton of steel allows you to look at what is possible. Best Practice Approach Other measurments issues Primary energy is the amount of energy delivered to an end user adjusted to account for the energy that is lost in the generation, transmission, or distribution of the energy Site Energy versus Primary Energy Looks at how much an energy unit costs. Physical Units
versus Economic Units Legal aspects in New Zealand In New Zealand energy efficiency is outlined by Energy Efficiency and Conservation Act 2000. The energy efficiency for

air conditioners,
heat pumps,
low-pressure water heaters,
refrigerators (commercial or domestic),
three phase induction cage motors
fluorescent lamps

is subject to Energy Efficiency (Energy Using Products) Regulations 2002. Those regulations set the minimum efficiency and labelling those specific products must meet in order to be sold in New Zealand Energy Efficiency and Conservation Authority EECA claims delivering energy savings at an effective rate of 6.2 cents per kilowatt hour. Improvements in energy use is achieved in two ways Technology improvement Behaviour change From candle To gas Thomas Edison and the first light bulb Then economic light bulb came along and LED's what's next? Political will While energy management can be done at home or business, at large level is a government job. New Zealand Energy Strategy proposes the Government’s direction for energy and the role energy will play in New Zealand’s economy. It covers the supply, delivery and use of energy. It offers direction for the energy industry, for energy-related aspects of transport, housing, research and development and infrastructure. Also specifies directions for energy efficiency, conservation and renewable energy. According to EECA the residential sector accounts for 13% of New Zealand's national energy consumption per year, including 33% of all electricity consumed. Energy in

In buildings, most of technology to achieve a zero fossil-energy is available but not sufficiently demonstrated Long term perspective long range R&D in building sector is required with opportunities related to advanced ventilation, advanced windows, thermodynamic cycles and ultra-thin insulators A long-term R&D program will be required to develop batteries with much larger capacity than is needed for plug-in hybrid electric vehicles We conclude by emphasizing that technology alone
will not lead to the potential gains in energy efficiency.
Crafting and implementing wise policies are key to any success. That's why we left this star for you to fill in. Presentation made with Prezi
