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.

Barnaby Joyce says he would be '100%' behind the government constructing coal-fired power stations if that would lower the price of electricity.
South Africa's power utility would do well to consider swapping out expensive new coal-powered capability for renewables.
On Q&A, Minister for Urban Infrastructure and Cities Paul Fletcher said South Australia's high electricity prices were "the consequence" of Jay Weatherill's renewable energy policies. Is that right?
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.
To understand what happened to our love of giant radioactive kettles, take a look at cultural theory.
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?
A new rechargeable 'proton battery' - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
'Virtual power plants' offer extra power to the grid by tweaking the operation of batteries and appliances right across the network. But even this might be too blunt a tool for our future energy needs.
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.
Two decades ago, the then SA premier, John Olsen, defied a campaign promise and announced plans to privatise the state's electricity industry. It's been a high-voltage issue ever since.
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.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
The European Investment Bank's funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
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.
Critical thinking is of paramount importance, especially as it applies to research on the internet -- and to our energy future. Educators have a duty to ensure students avoid fake news on energy.
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.
Fill a tank with water, sugar, and old mobile phones. Add bacteria and stir. Result? Rare earth metals. This is biomining, and it's the way of the future.
Raising the cost of solar panels coming to the US could rekindle interest in a simple but potentially significant technology: solar reflectors.
Slapping duties on imported panels is unwise.
