Without energy storage technology we’re leaving good energy blowing in the wind. Danny Lawson/PA

When the wind blows we must capture it for a calmer day

The handling of Britain’s energy strategy leaves much to be desired, subject as it is to short term politics over long term planning. We face a trilemma that stems from the opposing tension of climate…
How selfish! Are solar panels really pushing up the price of power for everyone? Elliot Brown

More solar, less power demand, higher prices: does it add up?

If I install solar panels and a car battery to run my air conditioner, should I pay higher electricity network fees? The electricity industry and Queensland’s Energy Minister would say yes, but is that…

Nuclear futures: renewables blossom in Germany’s post-nuclear vision

When the Fukushima Daiichi nuclear power plant in Japan was hit by a tsunami in March 2011, the disaster had a profound effect on German energy policy. Chancellor Angela Merkel reasoned that “Fukushima…
Ocean power can be harnessed for electricity generation using both wave energy and the tide. Scottish Government

Explainer: what is ocean energy?

Renewable ocean energy harnesses the power of the oceans to produce electricity. This can be done in several ways, but the resources that have the most immediate potential in terms of energy production…

The Federal Budget has attempted to fill a A$6 billion revenue hole left by the collapse of the EU carbon price - but has cut into renewables as a consequence. John Goodridge

Budget defers renewable energy development when it’s needed most

The decision to link the Australia’s carbon price to the European Union emissions trading scheme has wiped A$6 billion from the federal budget. Treasurer Wayne Swan has dealt with that loss of revenue…
