The demand for energy in form of electricity is increasing across the world. The estimated consumption of electricity which was 13250 Twh (Terawatt Hours) in 2007 is expected to rise to 40000 Twh in 2040. With increasing focus on generating electricity from green sources, the gap between electricity supply and demand will grow even larger. If the gap between demand and supply is not closed in a cost effective manner, either the price of electricity to the end consumers will go up or the governments across the word will have to subsidize it. In both cases, the BOP segment which already has a limited access to electricity will continue to be deprived of access to reliable and affordable electricity. Trying to close this demand-supply gap using fossil fuels by increasing supply will have disastrous consequences on climate, which will again affect the BOP segment the most. To close this gap without affecting the quality of life and not much investment, it is also important to improve on the demand side of electricity consumption.

Use of energy efficient lighting
A major portion of electricity generated today is lost because of use of inefficient appliances and lightings. Use of energy efficient appliances and lightings can greatly reduce peak energy load and significantly increase the utilization of available power without having to invest in expensive electricity generation facilities. Around the world the household and commercial sector accounts for around a third of electricity usage and lighting is almost a third of that. Majority of lighting is obtained from incandescent bulbs. Based on a 100 year old technology, the incandescent bulbs converts only 5% of the electric energy into light and waste the rest as heat. A huge amount of savings in electricity consumption can come simply from use of efficient lighting by all sections of customers, both BOP and non-BOP.
From the energy saved by using efficient lighting India would be able to electrify 41 million more homes, and South Africa 8 million homes, without making any new investments in electricity generation.
Lightings are required by all, the process to move away from incandescent bulbs is very easy, switching cost is relatively low, and consumers can see immediate savings with lower electric bills. These incentives should help quick adoption of efficient lighting by all customer segments BOP and non-BOP. Also the grid connected BOP customers use electricity mainly for lighting so compared to development of other efficient appliances, development and easy availability of efficient lighting will help them the most. Use of efficient lighting will also help spread the use of solar powered to off-grid BOP consumers as relatively smaller, cheaper and portable solar panels and batteries can be used to get the same amount of light.

Target Market: All geographies and all consumer segments
A market analysis report by US Global Industry Analysts Inc estimates that by 2018, the global market for lighting fixtures will exceed US USD 121 billion and the market for lighting controls will be USD 8 billion. Countries around the world are beginning to phase out inefficient incandescent lamps by enforcing mandatory minimum energy performance standards for lighting. Companies competing in lighting industry can capture a larger share of lighting market by designing energy efficient lighting fixtures which meet the prescribed energy performance standards.

Innovation: Lighting fixtures based on LED (Light Emitting Diodes) technologies
CFL (Compact Fluorescent Lamps) and LED are the two technologies that have emerged to replace the incandescent bulbs. CFLs which are simply efficient miniature versions of full-sized fluorescents have gone out of favor because of the mercury content in them. The latest invention in lighting, LEDs or Solid State Lighting are more energy efficient than CFLs, have no environmental impact and have a very long life. LED light have an estimated

Energy Efficiency In California

Introduction California has been leading the nation with its energy efficiency programs since the 1970’s. Per capita electricity consumption has remained relatively constant for the state, yet the remainder of the US has increased by about 33 percent (California Public Utilities Commission). With concerns of energy security and climate changes playing a large role in policy making, it is important to understand how California has managed to maintain its electricity consumption. The purpose of this…

Energy Efficiency Through Energy Financing Districts Essay

OVERVIEW OF ENERGY EFFICIENCES There has been much focus over the past decade by the Government and the media regarding the benefits of renewable energy. All across the Midwest and Western United States, utility companies are benefiting from federal subsidies and tax credits to build wind farms and installing solar panel systems. Unfortunately, wind and solar still have major limitations. The unpredictability of wind farms force Utility companies to “cycle” coal plants, making them operate inefficiently…

University Energy Policy

Lancaster University Energy Policy Introduction Many large organisations in the UK have an energy policy. An energy policy is a report on how the company or organisation plans to save, and not waste, energy in their establishment. It usually states how the energy is distributed and how much is used. In this assignment I am going to research one organisation’s energy policy and look at their aims and how effectively they are using energy. Energy Policy Lancaster University recognises that all aspects…

Crockpot Executive Summary

Executive Summary This memo focuses on enhancing the thermal efficiency of a crockpot. The current thermal efficiency of the crockpot was found to be 25.8%. This low efficiency is due to heat loss to the environment, inefficient energy transfer design, and losses from assumptions made during testing. Based on our results, we are confident that insulating the exterior and implementing higher quality materials can greatly enhance the crockpot's performance. Background A crockpot is a kitchen appliance…

Structural Factors Affecting Efficiencies

1.3. Factors affecting efficiencies:[4] Factors which affect efficiencies can be divided into three groups: the structural factors, the functional factors, and the system factors and physical properties. Structural factors that affect efficiencies are for example flow patterns, tray types, outlet weirs, down comers, and tray spacing. Functional factors are for example flow, pressure drop, liquid entrainment, liquid channeling, flooding, capacity and eddy. System factors and physical properties…
