Australia is no stranger to tight water supplies, and fortunately that means smart water conservation strategies are being devised all the time. Australia is leading the way in everything from strategies to combat desertification to using renewable energy for desalination plants, and now it is putting that knowledge to work on six new infrastructure projects that can save 1.3 billion gallons of water.
There’s some interesting new data out on recent shifts in electricity demand and consumption, courtesy of the DOE/EIA.
In 2008, total U.S. power generation was 4.1 million GWh. In 2009, that fell by 4 percent, to 3.9 million. That’s a 4 percent reduction — clearly the result of the economic slowdown. Nothing surprising there.
What’s interesting, though, is how generation shifted by fuel type. Over the same year, coal-fired power generation fell by 11 percent, from almost 2 million GWh to just under 1.8 million.
Just how important is turning off computers at the end of the day in an office building? Very, if a company wants to save big bucks on electricity bills. According to UC San Diego researchers, 50-80% of a modern building’s electricity use goes to IT equipment, particularly desktop computers. A report last year showed that not shutting down PCs equated to $2.8 billion in wasted electricity. Still, many offices don’t encourage their employees to hit shut-down on their PCs for a variety of reasons, including updating software while everyone is out or being able to keep the computer attached to the network so information on the machine can be accessed at any time. However, Microsoft’s new Sleep Proxy system claims it can help cut energy consumption by 60-80%, without getting in the way of office systems.
At a presentation at the Oxford Energy Futures conference on June 11th, Andy Duff, non-executive chair of RWE npower, made some controversial assertions about the future of electricity in the UK. He focused on three propositions.
a) The UK cannot meet its carbon targets without new nuclear
b) Electricity demand will grow at 1% less than GDP growth
