High voltage electrons from Morocco to the UK. The blueprint for a global ‘internet of energy’?
12:53 | Electrifying everything with renewable technologies like solar PV, wind turbines and battery energy storage is a ‘holy grail’ that energy transition naysayers tell us is an impossible dream.
The mind-blowing thing we get WRONG about energy
9:49 | Fossil fuels still supply 80% of our energy. And people point to this number to say it’s impossible to switch to renewables. But their argument overlooks just how much energy we waste – and how we could do it better.
100% wind and solar is coming!
17:30 | 100% electrification from renewables, backed up with interconnections and energy storage is now just around the corner. But there are still bumps in the road. Can we overcome them in time?
Ocean Electricity Grid. How do they do that?
13:05 | What if you could build your electricity grid out at sea and just bring cables to shore where they’re needed?
Rethinking electricity grids
11:58 | The cost savings, energy efficiency improvements, and speed of installation that new materials are facilitating may just make the difference in the race for decarbonisation.
Heat Pumps: How cold rivers could heat your home
11:33 | Heating our homes with cold water! Sounds absurd? It’s not. Heat pumps are revolutionizing the way we heat and cool our homes and cities. We went to the German city of Mannheim to find out how.
Global renewables: Pioneering the energy transition
42:25 | To stop climate change, the energy system must be transformed worldwide. Very little time remains to accomplish this. But there are places where this renewable future has already arrived.
How to Harness Abundant, Clean Energy for 10 Billion People
13:06 | We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann.
Moving waste heat from industry to homes
12:44 | How about a well insulated shipping container that can handle 1300 degrees Celsius and be delivered to small operators who need low grade heat, or to district heating systems to keep you toasty warm in the winter?
Why You Should Ditch Deadly Fossil-Fuel Appliances
10:23 | Donnel Baird’s ambitious plan to rip the fossil fuel infrastructure out of aging buildings and upgrade it with smarter, cleaner, healthier technology.
Can You Run a Grid on 100% Wind + Solar? South Australia Shows Us How
12:06 | Welcome to South Australia, a place where the winds of change are quite literal and the sun doesn’t just warm our homes but also powers them.
Cheap, multi-day grid energy. FINALLY!
11:12 | A US company called FORM Energy is on the cusp of installing its first 10MW / 1 gigawatt hour iron-air energy storage facility.
The insane potential of Pumped Storage Hydropower
12:43 | Pumped Storage Hydro could literally be the lynch pin to get us to 100% renewable global electricity grids without having to pillage the earth (and deep seabed) of critical minerals.
Have we got enough minerals?
13:05 | Will batteries for hundreds of millions of future electric vehicles rob the planet of all its precious minerals? And what about all the minerals and materials for billions of wind turbines and solar panels?
In-pipe energy: The hydro power nobody is talking about
9:06 | Around 4% of global electricity is used for providing tap water. That number is only going to increase and its carbon emissions rival that of aviation. But a surprisingly simple idea can make our water supply more sustainable: In-pipe energy.
This is what’s REALLY holding back wind and solar
11:57 | Building solar farms and wind parks is one thing. Plugging them into the grid is another. How does our power system need to change to cope with more renewables?
Revolutionising power transmission
13:55 | The energy transition solutions of the 21st Century will take many forms, with a complex mix of different power producers. Moving energy across ever greater distances will overcome much of the intermittency of renewables like wind and solar.
