Electricity Efficiency
Electricity is among the most important and commonly used forms of energy. Unfortunately, because it is so important, discovering ways to make it more efficient is an important part of the energy research and debate. By improving efficiency, we can reduce the demand upon natural resources, reduce the cost of energy, and limit the release of pollution into the environment.
Efficiency measures are the most cost-effective way to reduce energy consumption and climate change, since it does not require any new technology or tools. The most popular efficiency measures are improvements to the many small ‘point sources’ of electricity use, such as light bulbs and household appliances. For instance, compact fluorescent light bulbs (CFLs) use only a fraction of the energy of an incandescent bulb, producing the same amount of light. Other efficiency measures include identifying and understanding how buildings and industrial processes use energy and then using this information to increase their efficiency. Improvements to electrical grids, such as better insulation and better design, can also increase efficiency.
Industrial processes, which account for more than 70 percent of global energy use, are some of the most energy-intensive systems in existence. By discovering new ways to make these processes more efficient, energy waste can be reduced and money can be saved. For instance, industrial processes can be improved by improving the design of equipment and processes, reducing energy losses in transmission and conversion, and introducing techniques such as waste heat recovery.
Another important aspect of electricity efficiency is smart grid technology. Smart grids enable electricity to travel more efficiently along power grids by using intelligent controls and automated decision-making tools. These tools can help match the supply of electricity with demand in real-time, which means electricity use is optimized. Smart grids can result in greater efficiency, improved reliability, and lower electricity bills.
Finally, many companies are turning to renewable energy sources such as solar, wind, and geothermal power to reduce their reliance on traditional, non-renewable sources of electricity. All of these renewable sources are becoming more efficient, as well as less expensive, providing additional incentives for companies to switch to them.
Overall, improving electricity efficiency is an important part of the effort to reduce energy consumption and combat climate change. In addition to improving the efficiency of individual items and processes, the use of smart grids and renewable sources of energy will play an important role in improving efficiency. Companies that are able to improve their energy efficiency stand to benefit from not only improved performance, but also lower energy bills.
