Why go to all that bother when you can just half-fill the kettle?
The potential to harm local birdlife is often used to oppose wind farm development. But research into how birds die shows wind farms should be the least of our concerns.
Wind turbines kill some birds, but their contribution to total bird deaths is extremely low, as three studies show.
Why were so few complaints about wind farms investigated further? And who made these complaints anyway?
Have the hordes of wind farm complainers all gone shy?
Public rally against wind farms failed to really draw a crowd.
At a time when we are seeing unparalleled increases in renewable energy and reductions in fossil fuels all over the world, one wonders why this is still under public discussion in Australia.
Connecting renewable energy across Australia will help generate reliable electricity.

We always hear that renewable energy is getting cheaper, but what does that really mean?
The Canadian study found turbines produce a maximum of forty six decibels, around the same as a dishwasher.
During the Abbott government, the often recalcitrant Senate cross bench was thrown a big, juicy bone plainly intended to sweeten their disposition toward government bills which needed their support to…
Tony Windsor at his Werris Creek property with Mackdog, who’s a hit on social media.
There is one question that Tony Windsor, the high-profile former crossbencher from the Gillard years who is attempting a comeback in New England, is unwilling to answer. That is: in the (admittedly unlikely…
How long do we wait for evidence of harm before accepting something is safe?

A moratorium on wind turbines until we know they're safe sounds like a good idea, but it's likely that those calling for a ban will never be satisfied with the evidence.
A solar array goes up in New York. Is this the best place to locate solar, given the relatively clean New York state grid?
The wind and solar industries scored a huge win by getting extended tax credits, but research shows this isn't the best policy for lowering emissions through renewable energy.
Infrasound is generated by wind turbines, air conditioners, and a host of natural phenomena.
At the centre of claims about wind farms allegedly causing health problems is the infrasound that wind turbines generate as they turn in the wind. Infrasound is sound below 20Hz, which is generally inaudible…
Renewable energy developers choose sunny locations, which can be near protected lands.
Study shows that many of the utility-scale solar power plants in California have been placed near protected and environmentally sensitive lands.

The UK's first new nuclear power station since the 1990s is coming at the expense of renewable energy and leaving us unnervingly in hock to the Chinese.
A cloud of gloom settled over the renewables industry during Tony Abbott’s prime ministership.

Imagine a wind turbine, but underwater, not fixed to the seabed, and able to work 24/7.
To no one’s surprise, a US study found that solar panel cells produce infrasound and low frequency noise which is way below audibility.
Internoise is the world’s premier research conference for acousticians. The 2015 meeting is being held right now in San Francisco. Buried among the hundreds of papers is one that you could easily take…
Broadcaster Alan Jones said on Q&A that the cost of wind power far outstrips the cost of coal power.

Broadcaster Alan Jones told the Q&A audience this week that coal fired power costs about $79 a kilowatt-hour, while wind power is about $1502 a-kilowatt hour. Is that right?
The research never mentions wind turbines, only low-frequency noise.

The Australian newspaper’s campaign against wind farms continued this morning with a page one story from the paper’s environment editor Graham Lloyd.
The confirmation by Trade Minister Andrew Robb that the Clean Energy Finance Corporation (CEFC) has been ordered to cease future investments in wind power is a major setback to renewable energy, investment…
Badly sited wind farms may pose a threat to Bearded Vultures in southern Africa.
Wind farms are responsible for a large number of bird deaths. Finding a way to ensure that they can co-exist is vital.
