A couple of posts caught the attention of Earth’s Energy this week on how humans can reduce their electricity bills by reducing wasted energy.

newsnet5 tells us about appliances in our homes that use the most electricity at night and drive up our electricity bills. The biggest users include our cable tv and satellite tv boxes and coffee makers.

On a global note, the International Energy Agency (IEA) says wasted energy from electronic devices such as smart phones, tablets and game consoles cost the planet $80 Billion (€53 billion) last year. EurActiv adds that by the end of this decade, the sum lost due to inefficient product design is expected to grow to $120 billion (€88 billion).

Around 14 billion electronic devices are currently used by a small proportion of the world’s population, but that number could rocket to 500 billion in 2050, causing ‘alarming’ increases in energy demand and wasteProducts such as set-top boxes, modems and printers often use as much power when on ‘network standby’ as they do in power mode. In 2013, such devices collectively gobbled up 613 TeraWatt hours (TWh) of electricity, more than Canada’s entire electricity consumption that year.

Studies show that 80% of energy demand from games consoles is used just to maintain network connection and 65% of this figure could be cut by implementing best available technologies.

Meanwhile, in Biting back at power-draining ‘energy vampiresTech Page One explores efforts businesses and governments can take to reduce their growing electrical and heating costs in their offices and buildings. High users of electricity include water coolers, space heaters, vending machines and coffee makers that tend to be left on all the time and consume large amounts of energy.

On a national basis, standby power accounts for more than 100 billion kilowatt hours of annual US electricity consumption and more than $10 billion in annual energy costs (and)…many plug loads [any device plugged into an electrical outlet] are projected to use even more energy than they already do….Plug loads are responsible for up to 30 percent of companies’ electricity costs, according to a 2013 plug-load research summary published by the U.S. General Services Administration. 

The post discusses how automated systems and smart technologies can power down energy wasters at the end of the day to reduce the drain on the planet’s electrical grids.
