The Somerset Wildlife Trust (SWT) will be raising awareness about the fragile future of wildlife in Somerset, as well as other environmental issues, such as climate change.
Situated in a yurt (a 24-ft wide Mongolian-style tent) in the Green Futures Field, the SWT will also be spreading the word about the benefits of switching to an environmentally friendly energy supplier.
As well as being able to chill out and turn on, Glasto-revellers will be able to generate their own electricity and recharge mobile phone batteries.
Simply winding up a charger by hand for three minutes provides enough energy for up to eight minutes talk-time and an hour of stand-by time.
Festival-goers will also be challenged to pedal the Energy Bike (a specially adapted mountain bike) hard enough to power different household appliances.
The varying levels of pedal power required allow riders to compare energy-efficient appliances to inefficient ones, and to realise that equipment left on stand-by still uses electricity.
The laptop, attached to the bike's handlebars, displays the changing amount and cost of the energy the rider is producing, together with the CO2 savings made by not burning fossil fuels to generate that energy.
SWT Chief Executive Simon Nash said: "This is an exciting opportunity to spread important messages about the future of wildlife in Somerset, and beyond, to around 150,000 people."
