Former Vice President Al Gore has invested $600 million of equity into UK energy startup Octopus Energy Group via his Generation Investment Management vehicle, taking a stake of approximately 13% in the business. The investment means Octopus has attained a valuation of around $4.6 billion.

Octopus has made a name for itself in energy circles largely because of its ‘Kraken’ technology platform, which it claims is able to re-route energy from renewable sources around a network far more efficiently than competitors. Octopus is now managing 17 million energy accounts in 12 countries in this manner.
