Earlier this month Tesla CEO Elon Musk unveiled fashion-conscious solar roof tiles that generate more power than your lights, appliances and car batteries will ever need.
Unfortunately however (and like most Tesla products) this breakthrough innovation won't be available to your run-of-the-mill homeowner, because of its luxurious pricing structure.
In the heart of India however, two brothers are working on making sustainable energy affordable to the common man.
Arun and Anoop George are the founders of the Avant Garde Innovations start-up.
Their most recent creation is a small-scale wind turbine that will be priced at Rs 50,000 (around £600) – about the same price as the latest Apple iPhone, if not cheaper.
It measures the size of a ceiling fan and can generate three to five kilowatt hours of electricity each day, enough to power an average-sized home.
"We have made this turbine at a cost that is almost unheard of in [India] so far," Arun tells India Today.
"Our goal is to eliminate energy poverty, reduce dependence on struggling state power grids and create energy self sufficiency for all."
He explains how the small price of the wind turbine will make it affordable to Indian consumers whose other options are imports, which can cost over Rs 2 Lakh (£2,400).
India has emerged as a huge player in wind power over the years – and it's still expanding.
This is because the South Asian country has more than 4,500 miles of coastline and mammoth levels of wind density on its western coast, according to Energy Alternatives India.
Global Wind Energy Council ranks India as the fourth-largest installer of wind turbines, after China, Germany and the US.
The ultimate goal for Arun and Anoop is to power over a billion people across the world as part of collective efforts to make the switch over to 100% clean and affordable energy.
