If the efficiency is 80 per cent, 80 per cent of the original electrical energy reaches its destination. In this case, 20 per cent of the electrical energy is referred to as power loss. The classic light bulb exemplifies how high this power loss can be. An incandescent light bulb can have an efficiency of as low as five per cent.
These systems typically consist of photovoltaic solar devices and energy storage equipment [, , , ]. Under sunlight, photovoltaic devices can convert solar energy into electrical energy, which is stored in complementary energy storage devices.
This means 340 kWh conversion losses and 131 kWh losses due to self-consumption. The energy available from the storage system minus the losses is then 2,000 - 340 - 131 = 1,529 kWh. In other words, the efficiency in this year is around 76.5 per cent. In principle, a higher degree of efficiency is desirable, as less energy is lost on the way.
Several low carbon energy resources will contribute to tomorrow's energy supply landscape, including solar, wind, and tidal power, yet rechargeable batteries will likely remain the dominant technology for storing this energy and using it in an economic and efficient manner for decades to come.
