The good news is, they can cost up to 21% less than the average energy bill in Australia, depending on where you live.

Greenpeace’s hotly anticipated Green Electricity Guide has received an incredible makeover, revealing Australia’s greenest energy providers that are worth signing up to if you’re an environmentally conscious Aussie.

Plus, they won’t break the bank.

Quick overview

  • Both Enova Energy and Diamond Energy tied for first place with a perfect 5-star score
  • Momentum Energy rounds up the top 3 with a 4.5-star score
  • Powershop dropped to a lowly ninth after details were revealed of its merger with Shell last year (it had claimed top spot in the 2018 version of the guide)
  • AGL came in last with a 1-star score, largely due to its plan to burn coal until 2048

Good to know

  • The Green Electricity Guide was developed taking 6 criteria into account: that the companies provide clean, renewable energy; they’re committed to ending coal use by 2030; they’re halting fossil fuel expansion; their support for new renewable energy; transparency in marketing; and pollution and environmental harm.
  • 28 of the 48 providers that were rated in the Green Electricity Guide scored 3 stars or below.
  • 76% of Australia’s electricity still comes from the burning of fossil fuels.
  • If you don’t want to switch energy plans, you could add on anywhere between 10% and 100% GreenPower that will allow companies to send renewable energy to grid on your behalf. It’ll cost you about $150 per year if you opt for 100% GreenPower.
