Lack of grid capacity is already a key barrier to deploying renewables & electrification. A solution: grid hosting capacity maps. Here's our RAP @ember_energy proposal for what this could look like in Europe 👇 Mock up in video below.

I have known Le Porge since I was a child. Much of it is now ash. We were warned this would come. We kept burning fossil fuels anyway. Adapting to this is not a plan. Stopping the cause is.

I just told BBC News (UK): Energy crises are fundamentally demand problems, not supply problems. 80% of our energy is fossil fuels, much of it imported, leaving us exposed to price spikes. The only long-term fix: electrify the economy with clean power.

Using old coal mines to heat homes? Gateshead is doing it. Their mine-water project—the UK’s largest—draws 15°C water from boreholes, uses heat pumps to boost it to 80°C, and sends that heat through an underground network. The system now warms 350+ homes and 23 buildings.

When I'm told on social media that heat pumps don't work in old buildings I usually invite people to my 144 Victorian house in Oxford to see it with their own eyes. So far no one has accepted the invitation so I allow you to virtually step inside my house. Come on in! PS: I know I lost some hair and some weight since that video was shot. I would not mind getting back some hair but I don't need the extra weight.

Two-thirds of global energy is wasted, mostly as combustion heat. Electrification gets rid of most of that waste rather than replacing it. From my keynote at the Eurelectric PowerSummit.

TODAY: Europe’s Largest Battery Storage Site Goes Live at Blackhillock, Scotland. A major milestone in the UK’s push for a net-zero power grid by 2030. It has a capacity of 600MWh – enough to power 3.1 million homes for 2h.

The Talatan Solar Park in China is absurdly huge — stretching across 600 km² of the Tibetan Plateau (about 7× Manhattan’s size) and generating around 17 GW of power. It’s so big you can see it from space — a shimmering sea of panels.

The mind-blowing thing we get WRONG about energy: Our current energy system is very inefficient - we waste most of the energy in conversion processes. The good news: With electrification and renewable energy many of those inefficiencies will disappear. Video by DW News

The world’s largest electric vehicle isn’t a car or bus—it’s the eDumper, a 45-tonne mining truck in Switzerland. It hauls 65 tonnes and can finish a shift with more charge than it started, thanks to regenerative braking. If we can electrify mining trucks, what’s next?

What if we had no electricity and everything ran on fossil fuels? This ad keeps making me chuckle. Enjoy if you have not seen it or rewatch as it is just gold.

How did Sweden become a heat pump super power? Listen to Sweden's inspirational story. In 10 minutes I explain how Sweden has installed millions of heat pumps and what we can learn from it. The video is from a recorded Nesta event in London from two weeks ago.

Germany just connected its largest battery storage system—103.5 MW in Bollingstedt. Big step for grid flexibility and renewables! Projects like this are key to a resilient, clean energy future. More here:

Starting in 2016, today the world invests far more in clean energy than in fossil fuels.

Data centres are energy hungry but what if we could use their waste heat to heat our homes? That's exactly what happens in places like Finland: Cities are tapping the vast amounts of waste heat generated by data centres, and feeding it into district-heating networks.

Can a medieval town replace fossil heating with clean energy? Yes it can! Here's an inspiring example from a place close to home for me - I grew up just a few miles from the German town of Lemgo founded in 1190. Many of Lemgo's buildings are very old and listed. The city is using district heating in combination with advanced heat pump technology, extracting heat from its wastewater treatment plant and the nearby River Bega. Lemgo has also installed solar thermal systems and aims to generate over 55% of its district heating from renewable sources by 2028. Investments in large-scale heat storage are also underway to further support the transition.
