Momentum is a 100% Australian-owned energy company supplying gas and electricity to its customer base across Australia. Momentum has won multiple awards for customer satisfaction in recent years, and prides itself on offering energy from renewable sources through its parent company, Hydro Tasmania.

Momentum Energy is a publicly-owned company. Its parent company Hydro Tasmania is owned by the Tasmanian Government. Hydro Tasmania claims to be "Australia's largest generator of clean renewable energy", and generates power through hydro electricity and wind farms.

However, while its parent company is a renewable energy generator, Momentum Energy supplies power from the National Electricity Market (NEM), which is a pool of electricity generated by a range of sources, including fossil fuels. Therefore the product Momentum supplies is not necessarily from renewable sources. 

In 2016, Momentum was fined $54,000 for 'greenwashing', that is misleading customers into thinking the product offered is better for the environment than it actually is. The company's website now clearly states that its electricity is sourced from the NEM, and can therefore not be considered 100% renewable. Momentum offsets a portion of its carbon production, however, neither the organisation nor the product offered are carbon neutral.
