Generating power from the sun, the wind and from cheese - why green energy firms are seeing red over cuts in state subsidies. Evan Davis and guests discuss a zero-carbon future.

After the Paris summit on climate change and the global commitment to cut carbon emissions, The Bottom Line is going green - with businesses that generate energy from the sun, the wind - and from cheese. And, whilst the government is committed to getting more of its energy from renewables, Evan Davis and guests discuss why green firms are seeing red over cuts to subsidies they say are vital to update ageing infrastructure.

Guests:

Juliet Davenport, CEO, Good Energy

Jeremy Leggett, Founder, Solarcentury
