The power modules of home appliances have poor efficiency, which is one kind of problem. Generally, we have no considered this type of problems due to maximum consumers are used AC (Alternative Current) Energy. AC energy is generated by using conventional energy, which is not environment friendly, but power generation cost is very low that why the power modules of home appliances of efficiency is not major issue.
We use to do more energy efficient device to save the energy and reducing electricity bill. Energy conversion is broader than energy efficiency in including active efforts to decrease energy consumption, for example through behavioral change, in addition to use energy more efficiently. Examples of conservation without efficiency improvements are heating a room less in winter, using the car less, 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. This is especially the case when actions are directed at the saving of fossil fuel. Energy conservation is a challenge requiring policy programmers, technological development and behavioral change to go hand in hand. Many energy reorganizations, for example governmental or non-governmental organizations on local, regional, or national level, are working on often publicly funded programmers or projects to meet this challenge. For Renewable energy, power efficient is most important issue.
