Africa is blessed with an abundance of sunshine.Given the heavy demand for energy, alternatives, such as solar, could provide solutions and help stimulate economic growth.
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.

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.

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.
Low carbon choices such as solar power are essential for the African continent, if it intends to stop the harmful global warming effects.

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 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.
