One of the more drastic approaches to addressing climate change has been the concept of geoengineering, in particular ejecting particles into the upper atmosphere to cool the planet. However, according to the USA’s National Oceanic and Atmospheric Administration (NOAA), such a move would see reduction in electricity generation by solar farms that concentrate the suns energy using mirrors and lenses.
A major challenge for desalination plants is electricity consumption – and in creating that electricity, huge amounts of water are required at the power generation source. This is an area where solar power can again come to the rescue.
Deep cycle batteries can store large amounts of power – but they are rather bulky.Lithium-ion batteries, such as those found in notebook computers, are much lighter and able to store significant levels of energy too – but they can take a long time to recharge. A new battery technology developed by MIT engineers dubbed “beltway battery” gets around this problem and may help propel Lithium-ion technology into the wind and solar related energy storage market much sooner than expected.
Research from the Helsinki University of Technology’s Advanced Energy Systems asserts renewable energy technologies like wind and solar power could supply 40 percent of the world’s electricity by 2050 if given similar support as to what the coal fired and nuclear industry receives.
The Victorian Government yesterday provided further details on a series of projects designed to boost the uptake of solar power in the state and to help Victoria meet its renewable energy targets.
A team at MIT is currently working on a new approach to deep cycle batteries using chemical reactions of liquid materials that could be applied to small and large scale energy storage applications.
There was a flurry of media activity yesterday and today ahead of the release of the Australian Government’s Emissions Trading Scheme draft legislation, which was unveiled a short time ago.
The greenest megawatt of electricity is the one you don’t have to generate – and if last year’s Earth Hour is any indication, quite a few megawatts will be saved during the upcoming event.
The dedication last Friday of Atlantic City Convention Center’s new solar roof heralded the end of the largest single roof-mounted grid connect solar construction project in the United States.
According to researchers at Penn State University, carbon dioxide emissions intensive industries could convert CO2 to a wide variety of hydrocarbons, such as methane. While methane is a powerful greenhouse gas, it’s a useful one that can be used for fuel.
