Hollywood actors Leonardo DiCaprio and Mark Ruffalo backed a campaign aimed at boosting clean energy.

They helped launch a pop-up event in New York yesterday which was also supported by small business owners, veterans, farmers, educators, artists and community leaders.

Mr Ruffalo, Co-founder of the ‘100%’ campaign, said: “Our first priority is to make clean energy more accessible and affordable for all people – increasing consumer demand and accelerating the growth of clean, efficient renewable energy – 100% is for 100%.”

The campaign was launched in New York and is to be rolled out across the country.

A ‘100% hotline’ was available, providing clean energy concierge services and helped consumers switch to clean energy.

The event in the East Village also included a five-story tall mural by a street artist, banners showcasing clean energy leaders, solar powered pizza, new clean energy technologies and celebrity stunts.

In a poll conducted by Clarity Campaign Labs, 77% of New Yorkers supported renewable energy.
