In the Green Room with Trewin Restorick

Nov 15, 2017 - 3min read

In the Green Room, we talk to leading figures in sustainable technology to find out how environmental issues shape their lives and behaviour, and how they envision technology will change the world for the better.

Trewin Restorick is the brains behind Hubbub, an innovative charity that drives meaningful environmental change with creative campaigns that inspire people to make healthier, greener lifestyle choices – frequently in ways that help them save money.

He enjoys cooking and discordant music.

My (anti) tech hero is Evgeny Morozov.

He’s the author of The Net Delusion, and although his writing is like wading through syrup at times, we need people like him that question the wider impact of data being increasingly controlled by a small number of hugely powerful companies. The impact of this on democracy, land use, the movement of money and lifestyles is profound.

The most sustainable room in my house is the outside.

Okay, so it’s not technically a room, but we have solar panels on the roof for both heating and water. Indoors, there is a rather scary worm bin for kitchen waste which is viewed with extreme trepidation by the children, and a massively effective hot bin that turns garden waste into compost at an incredible speed. A water butt collects water for the house plants, and we grow a variety of herbs and vegetables in the small town garden.

My favourite sustainable company is IKEA.

We have to bring sustainability into the mainstream by making it affordable for all through quality design; IKEA is definitely on that path. They have made a significant investment in renewable energy and sustainable cotton. They are also using their position as a significant retailer to actively talk to customers about sustainability, and have plans for a whole host of new products that will help people live greener lives.

The real game-changer in sustainable tech will be driverless vehicles.

On the positive side there should be less congestion, less pollution and less deaths on our roads. On the downside there could be more urban sprawl and the impact on society of removing jobs traditionally filled by people could be significant.

We need a smarter national grid


We need a smarter national grid.

We need it to deal with the impact of bringing an increasing amount of variable renewable energy into our energy supply. This was the first time I realised the importance of technology to solving environmental problems. To cope with energy being supplied from remote areas, we have to store energy at times of surplus and use that to manage demand, particularly during peak periods.

As a kid my favourite bits of tech were the Casio keyboard and a Roland drum machine.

Showing my age, but with absolutely no musical talent I could easily play Blue Monday by New Order, making my teenage soul very content.


My guilty, unsustainable bad habit is not being a vegetarian.

All the evidence suggests that it is one of the most significant steps I can take as an individual but I haven’t quite got there yet. As a family we have stopped eating beef and will cut out all red meat this year but I am finding the transition difficult – particularly when trying to cook for two very hungry boys who are yet to be convinced of the benefits of non-meat alternatives.
