Enjoying that AC? Thank the mighty power of the sun and the renewable energy source keeping the grid afloat.

A storage device made from sand may overcome the biggest issue in the transition to renewable energy.

Parliament approves measures to use mothballed sites to produce electricity and preserve gas supplies

 Polar Night Energy's first sand-based thermal energy storage system for commercial use has begun running in Finland. The system installed by Polar Night Energy at the location of a power plant run by utility Vatajankoski has started operating. It is based on its proprietary technology.

Global nuclear power capacity needs to double by the mid-century to reach net-zero emissions targets. This will help ensure energy security as governments try to reduce their reliance on imported fossil fuels, the International Energy Agency (IEA) said on Thursday.

Scientists are building a micro nuclear reactor, which aims to be able to be significantly cheaper and faster to build than conventional light water reactors.

To avoid power shortages and keep the grid running smoothly, we may have to adjust our expectations around the transition to green energy.

The technology to turn nuclear waste into energy, known as a nuclear fast reactor, has existed for decades. Now, it's getting a second look.

Island states are often dependent on expensive imported fossil fuels for their power. Ocean thermal energy conversion plants could provide constant power – if technical issues can be overcome.

There are multiple routes to drop carbon emissions by 50% by 2030.

Wires have a lot going for them when it comes to moving electric power around, but they have their drawbacks too. Who, after all, hasn’t tired of having to plug in and unplug their phone and other rechargeable gizmos? It’s a nuisance.

President Joe Biden took some heat on Monday for saying the quiet part of the energy transition out loud. At a press conference following a meeting in Japan with Japanese Prime Minister Fumio Kishida, the President seemed to frankly admit that high gasoline and diesel prices are just part of the overall plan for the transition to renewables.

Tesla CEO Elon Musk has reiterated his skepticism about hydrogen’s role in the planned shift to a more sustainable future, describing it as “the most dumb thing I could possibly imagine for energy storage.” During an interview at the Financial Times Future of the Car summit on Tuesday, Musk was asked if he thought hydrogen had a role to play in accelerating the transition away from fossil fuels.

Exclusive: Oil and gas majors are planning scores of vast projects that threaten to shatter the 1.5C climate goal. If governments do not act, these firms will continue to cash in as the world burns

Scientists have discovered evidence that a key rare resource, called helium-3, is potentially ten times more common on Earth than previously known—though the source of all this extra supply remains mysterious, reports a new study. The finding is important because helium-3 could serve as a foundation of limitless clean power for our civilization, but has been seen as inaccessible since it is largely found in outer space locations, especially the Moon.

It is more urgent than ever for Europe to become self-sufficient in energy. This is accompanied by major power shifts, both within and outside the EU. What will the energy transition mean for geopolitical relations?

President Emmanuel Macron promised on Saturday to make France the "first great nation" to stop using oil, coal and gas as energy sources, in a pitch to young and green voters he fears could abstain in next week's election runoff.

Researchers have revealed a new thermophotovoltaic (TPV) cell that can convert heat to electricity with over 40 percent efficiency.

A breakthrough invention by a team of Stanford researchers allow solar panels to begin generating energy at night.

The future of solar has just got brighter with this ‘ultra-thin’ device for converting stored energy into electricity.
