5 ways energy efficiency is changing the world
Eco-Business, April 6, 2015
1. It’s making energy smarter
The power generation industry is the world’s largest energy consumer, and some fuel sources and technologies can be extremely inefficient. A plant’s electrical system can consume between seven and 15 per cent of all the energy it produces, taking away from its revenues and profitability.
2. It’s making your energy cheaper and cleaner
The process of generating power to users typically result in electricity losses of about 9 per cent globally. Technology innovations, such as high-voltage direct current (HVDC) systems could reduce these losses.
Power systems have historically transmitted electricity using alternating currents (AC), where the current flowing through the network alternates in direction at a predetermined frequency. While AC power was chosen over direct current (DC) – where current flows in a single direction – because it was seen as easier to interrupt or change voltage, it is less suitable than DC for carrying electricity over long distances.
