For much of society business carries on as usual, but huge changes are underway. Renewable energy is becoming the cheapest form of energy in many parts of the world, and the opportunity is here to create a rapid transition to a low carbon future. 

We will look briefly at the reality we are facing in our changing climate, the massive shift underway in the energy and transport sectors and the opportunities for local action to create climate friendly solutions and viable businesses in every community.

TEDxExeter: HOPE

8.30am – 5.15pm, Friday 21 April 2017

A day of inspiring talks, connection and action

“Critical thinking without hope is cynicism, but hope without critical thinking is naïveté.” — Maria Popova

TEDxExeter is back for a 6th year. We’re bringing another exceptional group of speakers and performers to Exeter to share their work, vision and hope with us. We’ll gather over 900 people on the day to share inspiration and explore ways of turning hope into action and making a positive difference in our lives, our communities and ultimately our world.

Live at the Exeter Northcott Theatre
Simultaneous Livestream at Exeter University’s Alumni Auditorium

Both audiences joined together in the breaks to meet each other, our speakers, sponsors, and groups making a difference locally. Lunch and refreshments were included in the ticket price.

“Optimists think it will all be fine without our involvement; pessimists take the opposite position; both excuse themselves from acting. Hope is an embrace of the unknown and the unknowable, an alternative to the certainty of both optimists and pessimists. It’s the belief that what we do matters even though how and when it may matter, who and what it may impact, are not things you can know beforehand.” — Rebecca Solnit
