Much of India's huge population is still without electricity, perhaps making climate action a tough sell. But India's vision for green development chimes well with the world's climate agenda.
Gas is the solution to some but not all our problems.
UK's decision to close coal power plants is really a statement of the obvious, and does nothing to answer the problem of what to do afterwards.
Mountain to climb? The Greens have set their sights on topping 90% renewable energy.

The Greens have backed a renewable energy goal of 90% by 2030. With wind and solar getting cheaper all the time, it's an achievable challenge.
Ahead of the Paris climate summit businesses have made pledges, including to purchase power from renewable generation.

What have businesses put on the table ahead of the Paris climate summit in December?
Real hot: the Ivanpah solar power plant and others like it use mirrors to produce heat to make steam and drive an electricity turbine.
The massive Ivanpah solar power plant uses natural gas – even more than it expected last year. It's not ideal, but solar power and natural gas are a powerful, and relatively 'green,' combination.
Losing steam? Older power plants are expensive to operate or upgrade.

Anti-nuclear advocates may cheer the closing of nuclear power plants in the US, but thanks to cheap natural gas, less nuclear power means higher emissions.
The University of California intends to be carbon-neutral by 2025 by implementing existing technologies and focusing on public education. Is this a model for decarbonizing at large scale?
Coal no more? The rise of renewables and climate action will spell an end to Australia’s coal industry.

Australia's failure to reassess its commitment to coal will have serious negative consequences, not only for Australia’s economy, but for the health and well being of millions of people and the global environment.
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.
India’s main aim is to get electricity to more of the population - using renewables where possible.

India has pledged to ramp up renewable energy and make its economy more carbon-efficient. And while that will help cut emissions, the main motivation is to give power to the many who still lack access to electricity.

Renewable energy programmes in South Africa need stronger policies to ensure that communities benefit.
Renewables could benefit from more energy storage capacity in the electricity network.
Energy storage is often considered the holy grail of the electricity sector. Great for households, it could be as important in the wider electricity network.
China knows the smart money is on renewables, and not just because of climate change.
China is pouring money into clean energy - not just to tackle climate change but because these are economically fruitful industries. And as China develops them, the technologies will get cheaper for everyone.
Change is coming for Australia’s energy sector. Time for our leaders to embrace it.
The key drivers for energy in the 21st century are managing climate change, shifting community concerns, and radical technology change.

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.
Good governance is a foundation for sustainable development under the new goals.
Later this week, world leaders will gather at the United Nations in New York and adopt a set of Sustainable Development Goals to guide global development.
Solar hot water may be green, but sometimes it can leave you out in the cold.

Solar hot water is an excellent way to heat up without adding to your electricity bill. Unfortunately, it seems Australians are not getting the most from their solar hot water systems.
A cloud of gloom settled over the renewables industry during Tony Abbott’s prime ministership.

Renewable energy investment dried up under Tony Abbott's prime ministership, as he made his antipathy to the industry clear. But Malcolm Turnbull has to do to revive the sector is call a simple truce.
Australia has 1.4 million solar rooftops. But it is with the addition of battery storage that energy grids will really be revolutionised.
