Analysts hope that South Africa’s new energy plan will have wind and solar plans.
South Africa's new energy plan is set to be announced.
Can Walmart go green while maintaining its commitment to low prices?

Two business professors spent five years studying Walmart's ambition project to bring sustainability to its millions of budget-conscious customers – a plan that began with the birth of a granddaughter.
What if it were a lot easier to install solar power?
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
Energy experts are getting excited about a proposed solar farm in Kent and what it could mean for a clean energy future.
Understanding how certain proteins deal with light absorption can inspire modern solar technology.
Proteins guard their secrets closely, but once you get them to "sing", there's an enormous amount to learn.
As the name suggests, Windy Hill near Cairns gets its fair share of power-generating weather.

There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.
The latest research suggests that in Australia, rooftop solar photovoltaics are more likely to be adopted by middle-class households.
Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.
The Khi Solar One concentrating solar power plant in South Africa.
Solar power technology has huge potential for Africa. But there are some barriers.
Solar lowers prices and shifts when daily peak demand hours are.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Rising seas, harsher weather, rainier days. The impacts of climate change make it harder for Caribbean countries to plan their transition toward renewable energy sources.
The 2017 hurricane season showed that Caribbean nations urgently need more resilient power grids. But the effects of climate change – including more severe storms – complicate the shift to renewables.
Block Island Wind, the first offshore wind energy project in the U.S., started operation in 2016.
A recent survey of electric utility leaders finds that Trump administration efforts to promote coal energy and roll back air pollution regulations have had little impact on their long-range plans.
The coils winding facility building in France, where a global effort to build the ITER fusion energy reactor is underway.
As fusion becomes more technically viable, it's time to assess whether it's worth the money because breakthroughs in the lab don’t guarantee success in the marketplace.
Grid-scale energy storage systems may make it easier to rely completely on renewable energy.
Saving power to use later lets consumers, businesses and utilities generate energy when it's cheap and deliver it when they need it most. There's not much of it today, but the industry is growing fast.

SA Liberal Party leader Steven Marshall said that state Labor policy had left South Australians with 'the highest energy prices in Australia' and 'the least reliable grid'. Is that right?

The fossil fuel era won't last forever. And a new set of countries will find their reserves of lithium, copper and rare earth metals are in high demand.
Looking through semitransparent cells – one day these could be big enough to make windows.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Puerto Rico’s power utility, PREPA, has been decimated by years of scarcity and bad management. But will privatizing it really turn the lights back on for Puerto Ricans?

Many Puerto Ricans are happy to see their broke power utility sold off to whoever can get the lights turned back on. But privatizing the island's energy grid may bring more problems than relief.
The Loy Yang power station ‘tripped’ early in the year, triggering fears of a summer of blackouts.
February is the riskiest time of the year for blackouts, as the nation returns to work and school and soaring temperatures put pressure on the system.
Now that panel costs in U.S. will go up, will reflectors make a comeback?
Joshua M. Pearce
Raising the cost of solar panels coming to the US could rekindle interest in a simple but potentially significant technology: solar reflectors.
