A new Grattan Institute report suggests solar panels in Australia might be more trouble than they are worth.
The Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
Tesla’s lithium-ion powerwall isn’t the only technology available for household batteries.
Lithium-ion is currently the leading battery technology for home installation, but others are just over the horizon that might be even better.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
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.
Batteries to store excess solar power will be a game-changer. But energy-efficient appliances will mean you can use a smaller battery.

The unveiling of Tesla's Powerwall home battery has been hailed as a huge moment in renewable energy. But don't forget the other innovations that can help you use that stored power more efficiently.
Amid the fanfare over the launch of the Powerwall, has Tesla’s Elon Musk struck a decisive blow for renewable energy?
Tesla's new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.
Elon Musk says the the Powerwall solar charged batteries could take a home off the electricity grid.
Not everyone will get the chance to cut their household electricity bills from solar powered batteries.
If Tesla Energy has its way, these big batteries will soon help power businesses and utility companies across the country.
Many of the targeted behavioral responses to climate change involve reducing energy consumption. This makes sense as the majority of energy consumed (pretty much throughout all history) has involved burning…
Coming to a grid near you.
Batteries combined with digital technologies will improve the efficiency and reliability of the electric grid, transforming how people use their energy.
The Tesla Model S - mean, and green?
The Tesla Model S is only as green as its electricity source - which is not very in brown-coal powered Victoria.
Both electric cars and renewable energy stand to gain significantly from cheaper storage.
Battery prices are falling faster than anyone expected: that's good news for solar power and electric cars.
Rooftop solar panels are disrupting Australia’s electricity market, and competing with networks.
The federal government's keenly awaited Energy White Paper is firmly focused on cutting prices and red tape, and boosting industry competitiveness - and less so on climate change and renewable energy.
Cool, now whose turn is it to make the tea?

A solar eclipse knocks out Europe's solar power generation while also causing a huge surge once people get bored. It's a unique energy challenge.
From Abu Dhabi, Solar Impulse 2 will travel east to India, China, and across the Pacific.
Solar powered aircraft might carry one pilot in relative discomfort, but don't expect airliners soon.
Use your solar photovoltaic panels to heat your water too, and you could cut the amount of excess electricity you give away cheaply to the grid.
Most solar power households feed excess electricity back into the grid, for very little financial reward. A hot water heat pump could put that power to better use, by heating water for evening use.
Renewables or oil? The former means betting each-way on energy storage. The latter means hoping to pull off a trifecta on carbon storage.
The question of whether the future will be powered by coal and oil or by renewable energy is crucially important, both to the medium-term future of the Australian economy and to the long-term future of…
Increasing Chinese investment in renewables is driving costs down.

Mining is the fourth-largest energy consumer in Australia, using roughly 10% of Australia’s total. Some of this comes from the electricity grid — but much is supplied offgrid in the form of diesel and…
It’ll come down to politics in the end.
Is solar power the technology of the future? It is certainly the fastest-growing energy generation technology in the UK. By the early 2020s, according to a new report, it will be cost-competitive with…
If Australia’s to have nuclear power, there’ll have to be policies to support it.
No sooner had foreign affairs minister Julie Bishop announced that Australia should take a fresh look at nuclear power than Prime Minister Tony Abbott responded that nuclear power would only be supported…
Roof-top solar panels are just one part of the micropower revolution.
There is no shortage of shouting and dire warnings about the state of the climate and our need to phase out fossil fuels. But there is a more silent revolution happening too — in micropower. Small-scale…
