Energy efficiency as necessary complementary measure Energy efficiency is a complementary strategy to the promotion of renewable energy. Indeed, the combination of low-carbon energy production with well-managed and effective energy use will pave the way towards sustainable energy systems. The industrial sector in developing countries is commonly characterized by relatively high energy intensity. While energy efficiency measures are often presented as low-cost (or even negative cost) options for reducing the energy demand, significant barriers of various kind remain for a wide-spread deployment and application of such measures. It is therefore of utmost importance to put emphasis on promoting technologies and policies to allow for the potential energy savings to occur. A regional support initiative focused on promoting business competitiveness and mitigating climate change, by raising companies’—preferably SMEs’—awareness and enabling them to adopt energy efficiency measures and use clean technology
Energy Usage in modern office buildings The main reason that contractors and building owners install AC inverter drives is to provide an efficient method of controlling the speed of the AC motors on the air conditioning machinery. Reducing the speed of the motor results in a reduction of the flow of air or cooling water and a corresponding reduction in the energy used. AC inverter drives are normally the most efficient means of controlling speed. This control method allows the air conditioning system to be constantly adapted to the demand on the building (number of people working, outside environmental conditions etc.) with the building owner benefiting by way of a lower electricity bill. There have been mechanical methods of adjusting flow rates available for many years. The AC inverter drive, however offers advantages in terms of efficiency and control which will be discussed in this presentation. In a modern building more than 50% of the energy used is consumed by the air conditioning system. The potential for savings is therefore very significant. In many countries government offers incentives to optimize the savings. Consequently new installations are invariably fitted with AC inverter drives.

An MNC in Delhi NCR was using SVLs and CFLs for their street lights and general lighting purposes and the cost of electricity and maintenance was high. They needed a reliable solution to cut their costs.
It was suggested the use of LED technology to decrease consumption and maintenance costs. 70 nos of LED street lights and 2448 nos of LED down lights were used. Savings for the first year were higher than INR 1,75,000 and 17,57,664 respectively
