There are 15 different kinds of electrical outlets around the world. One standard would be more convenient, but no one wants to change theirs.
Low-carbon energy sources aren't all equally well-suited to getting us to net-zero emissions.
Labor has pledged to create a A$20 billion corporation to upgrade Australia's energy transmission system. So what's this all about?
Energy-efficiency initiatives are consistently identified as the lowest impact and most cost-effective means of meeting energy needs. Why isn't Ontario focusing on them?
We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
Nuclear threats are serious – but officials, the media and the public keep a close eye on them. There's less attention to the dangers of cyberattacks, which could cripple key utilities.
Proposed rules for managing energy demand could potentially lower prices and reduce blackout risk, but there are reasons to be skeptical.
We need to equip Canada’s financial sector to steer us through a global economic transition on our own terms.
South Africa could become a test bed of technologies that enable households, especially in remote areas, to join electricity trading markets.
Solar and wind can't deliver power on demand. But overbuilding solar and wind, and simply dumping unneeded energy, would go a long way to smoothing out those bumps, study finds.
Electric utilities have a right to make money on their government-granted monopolies, but customers also have a right to know what cyber-protections they would get if they paid more.
Natural gas supplies are growing, but so are other markets for it besides power generation.
Making electric grids better able to withstand extreme weather events will require teamwork from engineers, researchers and the government.
Ensuring that everyone doesn't charge their cars simultaneously will make a big difference.
A year ago, the world's largest lithium-ion battery began dispatching power to South Australia's grid. It has been a remarkable success but there are some concerns that have so far escaped scrutiny
Federal Labor has promised to give rebates of up to $2,000 to 100,000 households to install batteries to store power from solar panels. Is this good energy policy, or just middle-class welfare?
The federal government is primarily to blame for the mess that is Australia's energy policy. It's time for the states to step up, to reduce both prices and emissions.
France, Germany and other European countries are increasing their use of renewable energy sources as well as storage solutions to help overcome their intermittent nature.
The announcement of a new fast-charging network to link the major east coast cities will do much to encourage motorists to buy electric cars. But the power utilities need to get on board too.
There are some good explanations for the mismatch between regional support for climate action and the areas where renewable energy is making the biggest inroads.
