The Australian government’s chief energy forecasting body has published a dramatic revision of its cost estimates, predicting that onshore wind and solar PV will deliver the cheapest forms of energy by 2030 — with solar PV dramatically cheaper than all other energy forms by 2050.
The Australian Energy Technology Assessment (AETA) prepared by the government’s Bureau of Resources and Energy Economics (BREE) slashes its previous estimates of the cost of a whole range of renewables technologies, and in some cases doubles the predicted cost of coal-fired generation in the decades to come — with or without the addition of carbon capture and storage.

A new research report from the Worldwatch Institute states that China leads in the global growth capacity for installed wind power.
The global growth rate for wind power capacity is continuing to grow at a lower rate than before due to various factors.
In 2011, the global installed wind capacity was four times more than that in 2005. In 2011 it grew at 21%, in 2010 at 24% and in 2009 at 31%. The investments for global wind energy installations in 2011 went down by 22% to $75 billion.

Not surprisingly, there was little excitement on the environmental policy front from this year’s Federal budget. This partly reflects the extensive environmental policy in the government’s Clean Energy Future Policy (CEFP) and partly their obsession with achieving a surplus in 2012/13.

VOTERS in Scotland appear to be turning away from wind farms, a new survey has shown, in a blow to the Scottish Government’s renewable ambitions.
A poll carried out for Friends of the Earth has revealed that just 18 per cent of people north of the Border put wind power as their first choice for future energy supply.
The YouGov survey showed that while 65 per cent believe wind should be part of the mix, this was down from 78 per cent seen in a similar survey by Scottish Renewables in 2010.
Instead the preferred choice in Scotland is for tidal and wave energy to become the main supplier with 32 per cent backing the option, even though it is still in its early development stage.
The latest survey was published as US billionaire Donald Trump arrived in Scotland to give evidence opposing wind turbines to a Holyrood committee on Wednesday.
