South Australia leads way in wind generation
PERTH AUSTRALIA - The premier of South Australia has stated that the states title as a leader in renewable energy will be confirmed when 1,000 megawatts MW of wind power capacity is brought online later this year.
Infigen Energys 39MW Lake Bonney Stage 3 project and Roaring 40s Hobart, Tasmania 111MW Waterloo Windfarm will take South Australia past the 1gigawatt GW mark.
The state expects to meet its renewable energy target of 20 of electricity generated from renewable energy ahead of schedule, and has stated that the next target is 33 by 2020.
Australias Macquarie Green Grid study says that South Australias Eyre Peninsula region has the space and wind resources to host a further 2,000 MW of conventional wind generation operating above 35 capacity.
At the end of June 2009, Australias total wind generation capacity was 1.494 GW, which is 1.2 of the total electricity generation in Australia. South Australia hosts 11 completed windfarms, and more wind power is generated in South Australia that in all other Australian states combined. This is due to its prime position in the Roaring Forties, which, in addition to being the name of a company mentioned above, refers to the latitudes between 40 and 50 degrees south, so called because of the strong and prevailing westerly winds.

How Bitcoin's vast energy use could burst its bubble
LONDON - The University of Cambridge Centre for Alternative Finance (CCAF) studies the burgeoning business of cryptocurrencies.
It calculates that Bitcoin's total energy consumption is somewhere between 40 and 445 annualised terawatt hours (TWh), with a central estimate of about 130 terawatt hours.
The UK's electricity consumption is a little over 300 TWh a year, while Argentina uses around the same amount of power as the CCAF's best guess for Bitcoin.
And the electricity the Bitcoin miners use overwhelmingly comes from polluting sources.
The CCAF team surveys the people who manage the Bitcoin network around the world on their energy use and found that…
