These trains don't break the laws of physics, but rather harness them in a way that results in a round-trip energy surplus.

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.

FISH and chip dinners will soar in price because offshore wind farms are likely to gobble up too much of Britain’s waters, a report warns. Fishermen say Boris Johnson’s plans for more turbines in the sea mean half of their territory could be lost by 2050.

Tesla has stepped up the pace of its utility-scale battery projects, and its Megapack installations in 2022 will help power utilities shut down coal- and natural gas-fired power plants.

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.

Even Exxon Mobil thinks electric vehicles are the future. The oil giant is predicting that by 2040, every new passenger car sold in the world will be electric, CEO Darren Woods told CNBC’s David Faber in an interview. In 2021, just 9% of all passenger car sales were electric vehicles, including plug-in hybrids, according to market research company Canalys. That number is up 109% from 2020 says Canalys.

Faster-charging, safer, longer-lasting solid-state batteries are on their way. The only question now is: How soon until we can plug in?

Hydrogen has a diverse range of applications and can be deployed in a range of industries.

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.

When landfills get capped and grassed over, they have the appearance of lush, rolling hills. Despite their green appearance, however, these sites are known as “brownfields”—a term for an environmentally hazardous site without a promising future. Indeed, landfills are typically unsuitable for development because the contents below the surface are both contaminated and physically unstable.

The world is undergoing a rapid energy transformation, with increasing capacities of renewable energy sources such as wind and solar power dominating. With the rapid decrease in the cost of renewable energy generation, there is an increasing need for energy storage technologies to ensure that electricity supply and demand are properly balanced.

The state of New York had recently passed a bill to introduce a ban on proof of work mining. It prohibited any new Bitcoin mining operations in the state. Passed by the State assembly in April 2022, the proposal was to ban mining operations of Bitcoin for the next two years. The bill is now headed to the governor’s office where the governor shall give his assent and turn the bill into effective law.

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.

One of the myriad issues with hydrogen as a clean energy source is infrastructure, as it's very expensive to move around and store an extremely explosive gas..

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.

The world's first ammonia-powered zero-emissions tractor successfully completed its first demonstration run at the Advanced Energy Center at Stony Brook University in New York last week. The midsized John Deere tractor had its diesel engine replaced with an "ammonia to power" system developed by a startup called Amogy. The system converts the energy-dense chemical into hydrogen, which then powers a 100 kW hydrogen fuel cell.

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

Starting this fall with its locations in California, the Swedish furniture giant Ikea will sell the means to power your Starkvind (that’s an air purifier) and Stjärnstatus (that’s a fridge) by adding solar panels to the company’s offerings. Thankfully, assembly will be handled by the professionals.

Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly.
