Humans are responsible for emitting over 40 billion tonnes of carbon dioxide into the atmosphere every year – and we all know that we need to reduce that figure to prevent devastating climate change. BBC CrowdScience listener Saugat wonders whether smart technology and artificial intelligence can help us do this more quickly?

Green energy will go a long way to tackling the problem, but integrating wind and solar into our current electricity grid is complicated. CrowdScience hears how artificial intelligence is being used at a wind farm on the island of Orkney to predict periods of high winds, so that excess energy can be turned into hydrogen and stored, then converted back to electricity when there’s greater demand.

Digital mirrors are also playing a major role in optimising performance. Scientists say cloud-based “twins” of physical assets like turbines can improve yield by up to 20 per cent, allowing engineers to identify problems via computer without ever having to be on site.

Presenter Marnie visits an intelligent building in London’s financial district, where sensors control everything from air-conditioning to lighting and machine learning means the building knows which staff will be on which floor at any given time, switching off lifts that are not in use and adjusting ventilation to save power. Its designer says incorporating this kind of digital technology will help companies achieve net zero more quickly.

And in India, more than half the population are involved in agriculture, but the sector is plagued by inefficiency and waste. Tech start-ups have realised there’s potential for growth and are using drones to monitor crop production and spraying, giving farmers apps that help them decide when and where to fertilise their fields.

    Meat might surprise you. Chicken and pork, for instance, are significantly less greenhouse gas intensive than beef. I've substituted two out of three days with beans for proteins.

    Gathering data for long enough and every farmer could have each individual probability-ai for when it'll probably rain and stuff. AND a decentralized network, easily compared to others - "Your data is WAY different from my data" "And from mine" "AND mine!" - 'Seems like I better check my device for virus then'

    We are unaware of environmental responsibility due to easy to getting from nature.if nature would be obtainable or something to make or create by human beings,we people who are involved in destruction of nature could never pollute our God gifted nature.

    I'm just shocked you didn't find a way to blame China

    Why thr ghraphics instead of viewing content ????? Ruins it for me!!

    I'm guessing there are a LOT of own-land farmers in India. I'm a bit sceptical that NO ONE will read subsequent. I have a friend in India. Most people in his village thought he was crazy for starting guided tours. Now he's among the biggest tour guides in the whole of India and his village has produced several more guides for tourists. It's enough if one or 1000 start. If the others see it's good then many will follow.
