Increased use of renewable energies could help curb climate change, but the water required for their production has dispossessed rural Guatemalans.
The European Investment Bank's funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.

A reliable water supply from Australia's mountain catchments depends on intact and functioning ecosystems.
The Snowy Hydro scheme already provides back-up energy to NSW and Victoria.
In its latest move on energy policy, the Turnbull government has unveiled a plan to boost generation from the Snowy Hydro scheme by 50%.

Catch 22: renewable energy can help fight climate change, but climate change might prove hard on renewable energy.
A red-and-green macaw in the Amazon.
New data have revealed a disturbing trend in forest loss: the hearts of the world's forests are disappearing. To stop them bleeding out, we'll have to say 'no' to some developments.
Tasmanian hydro power had a boom couple of years when the carbon price was in place.
A year after the demise of the carbon tax, we might expect both coal and greenhouse emissions to have bounced back, at the expense of renewables like hydroelectricity. Sure enough, that's what happened.
Investment in technologies beyond the existing wind and solar could stagnate in the face of the government’s reduced Renewable Energy Target.
After months of deadlock, a deal has finally been reached to reduce the Renewable Energy Target, ending the uncertainty for industry but also risking an already sparse pipeline of future projects.
Wind farms: great, unless it’s not windy.
Australia has some fairly ambitious goals for green energy: a renewable energy target (currently under review) of 20% of electricity from renewables by 2020, and a forecast to get 51% of electricity from…
Water storage is used to smooth the output from hydroelectric power - but it can be used with other renewables too.

More and more renewable energy sources are being plugged into Australia’s electricity grids. South Australia, for example, will get 40% of its electricity from wind and solar once the Snowtown wind farm…
Alcoa is to close its Point Henry smelter in Geelong.
Alcoa’s decision to close the Point Henry smelter, at a cost of almost 1000 jobs in Geelong and elsewhere, comes amid a perfect storm buffeting Australia’s aluminium industry. Point Henry will be the second…
South Australia produces plenty of wind power, but it might become more
than the grid can handle.
In late September, the Australian Energy Market Operator (AEMO) released a report investigating how wind can better be integrated into the power grid. AEMO reports that as more wind turbines are deployed…
