South Africa has made promises to decarbonise but is hugely reliable on coal - so this is difficult.
The process of decarbonisation is a complex one for South Africa, as most its power supply comes from coal.
Renewables could be a better answer to India’s power problems.
A new analysis suggests that, all things considered, renewables are actually better than coal at lifting India's energy-poor out of poverty.
Before jumping into the home battery market, make sure you do your research.
The 'early adopters' of home battery storage will pay significantly more than those who come later, but it won't be long until prices drop enough for many more to get on board.
The U.S. could dramatically increase solar and wind power without expensive energy storage. The key is to overlay high-voltage direct current power lines on our system of regional grids.
To decarbonise the electricity sector, Australia could increase the volume of renewables while closing old fossil fuel power stations.

The land of Ikea and apple charlotte is hoping to sell its vision of sustainability at COP21. There are a couple of meatballs in the ointment, though.
NASA once had 400,000 people working on space exploration. We should battle climate change in the same way.
South Africa has installed solar water heaters in low cost housing areas. It should be installing solar PV for energy.
South Africa has been slow to adopt renewable energy sources. One option, which has proved successful elsewhere, would be to install solar photovoltaic panels on rooftops in low-income areas.
A large solar thermal plant in Morocco will provide energy for 1m people – here's how it will work.
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.
When it comes to gas vs renwables, it seems the balance isn’t right.
Who'd want to take part in the UK energy economy when the government keeps changing the rules?
Coal no more? The rise of renewables and climate action will spell an end to Australia’s coal industry.

Renewable energy programmes in South Africa need stronger policies to ensure that communities benefit.
Low carbon choices such as solar power are essential for the African continent, if it intends to stop the harmful global warming effects.
For the sake of mitigating climate change, the African continent needs to make low carbon energy choices.
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.
The new Labour leader has been pilloried for extolling public ownership. In fact, he's bang on trend.
When we talk about saving water, we also need to talk about saving energy. The two are inextricably linked
Australia has 1.4 million solar rooftops. But it is with the addition of battery storage that energy grids will really be revolutionised.
