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.

Consumers of wind power pay twice: first via their monthly electricity bill and a second time as taxpayers to finance billions of dollars in subsidies.
BP’s energy outlook would make it difficult to keep warming below 2C.
BP's Energy Outlook report forecast an increase in fossil fuel use by a third. That would make it difficult to keep warming below 2C.

A new report shows Australia can and should double its energy productivity, increasing economic productivity while reducing greenhouse gas emissions.
Fossil fuels can only go so far towards meeting our burgeoning energy demands.
A non-metal alternative to platinum electrodes in fuel cells could make them an affordable solution for energy security.

Australia likely has several decades of coal left in it yet.
Australia likely has decades of fossil fuels left to extract, export and burn. That could prove to be a problem if the world comes to an agreement on climate change. Here's four ways to help the economy, and the climate.
Wind energy will be an important part of the world’s energy future - but it won’t be enough to feed growing demand.
Peak fossil fuel and action on climate change will mean we have less energy available to power the future.
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.
People are unlikely to experience ill-health further than 500 metres from wind turbines.
There is no direct evidence that wind turbines affect physical or mental health, according to a review of the evidence by…
Not coming to a motorway near you.
It sounds like something from the pages of books from the 1960s looking to the future: electric cars powered by current drawn from electrified rails beneath the road. However possible such ideas seemed…
Blowhards? The debate over wind turbines is heated, so it’s best to rely on solid science.
Yesterday, The Australian ran a front-page article about what it called a “groundbreaking” new study on wind turbines and their associated health impacts. The study supposedly found a trend between participants…
To find out if the carbon price worked, you have to look at the electricity sector.
Emissions fell by six times the rate in the five years before the carbon tax than they did under the carbon tax. – Environment minister Greg Hunt, The Guardian, January 17, 2015. Australia’s total greenhouse…
