11:27 | The US energy system has arguably never faced such an existential crossroads. As the rest of the world accelerates towards the inevitable clean transition, will America really allow itself to fall behind?
13:52 | Heat Pumps are the future of home heating. But until recently most companies have grossly over sized the Heat Pump systems they install…
13:08 | Communities all over the world have been badly affected by the closure of coal mines in recent years. But their proximity to grid connections and infrastructure make them ideal sites for new solar projects.
11:16 | There’s a big schism among energy system analysts right now.
11:38 | Materials scientist Jason Huang shows how we could massively upgrade the global power grid by replacing the wires in existing transmission lines with new, advanced conductors.
16:24 | I visited Greg Jackson at his London HQ to have a chat about what he’s up to.
12:30 | The old fashioned, centralised energy monopolies are crumbling to make way for distributed smart grids enabling us consumers to run appliances, energy storage, and electric vehicles while contributing to overall grid stability.
12:20 | The idea was simple: why not use solar energy from Australia’s sunny and spacious north to power Singapore, which has no space for renewables of its own?
12:33 | China is often held up as leading the way in renewable energy, but it’s actually the USA that has most enthusiastically embraced battery energy storage to help stabilize the electricity grid.
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.
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.
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?
13:05 | What if you could build your electricity grid out at sea and just bring cables to shore where they’re needed?
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.
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.
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.
13:06 | We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann.
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?
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.
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.
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.
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.
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?
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.
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?
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.
15:22 | Ramez Naam outlines the changes we need to make to get out of our own way and create a stronger, more reliable renewable energy grid.
7:45 | Why aren’t more people investing in Africa’s green energy?
8:00 | In Indonesia, where the majority of nickel for lithium-ion batteries is produced, the production process emits large amounts of carbon and pollution. It doesn’t have to be this way. Indonesia sits along the Ring of Fire, one of the most geologically active regions in the world.
10:28 | Liquid metal battery technology has the potential to revolutionise utility scale energy storage, but it’s been a long and difficult road for the creator, Donald Sadoway, and his company, Ambri Inc.
13:31 | Gas suppliers and boiler makers are lobbying hard for the use of hydrogen in domestic heating systems. But is that the right road to take?
11:10 | Gravity energy storage has real potential to provide cheap reliable grid balancing electricity to compliment the ever growing volume of intermittent renewables on our power grids, but only if it’s done in the right way.
11:42 | A video about capturing and utilising the enormous quantities of heat currently going to waste from more than seven million data centres and tens of millions of industrial facilities around the world.
14:20 | A team at MIT has combined and improved several existing technologies into a flexible modular solution that could be as much as 30x cheaper than existing lithium-ion technology.
16:19 | 15 million jobs are set to be lost from the fossil fuel industry in the coming years, but more than three times that will be created in the renewable sector.
50:07 | In the season opener, David Letterman travels to India. Back in the U.S., Cecily Strong travels to Florida and Nevada.
