Diamond Energy provides power to almost 15,000 customers across Australia, generating electricity solely from renewable sources. The company claims to provide more sustainable power than their competitors, at an affordable price.
First established in 2004, Diamond Energy is a privately owned power generator and retailer supplying sustainable power from renewable sources to Australian consumers.
The company is only partly Australian owned, with US solar panel manufacturer SunPower owning a 42% stake in Diamond Energy. While it is not carbon neutral, Diamond Energy owns only renewable assets and stands in strong opposition to investment in fossil fuels. Because of this, it claims to be 'beyond carbon neutral', with an emission intensity of -1.02.
Diamond Energy's electricity tariffs vary between states, but its Thr1ve program offers customers the opportunity to work towards a 100% discount on their bill through referrals, credits and bonuses, as well as other incentives.
