this is bbc news, the headlines: early signs suggest there's no clear winner in israel's general election. prime minister benjamin netanyahu says he'll now hold talks on forming a coalition. his main rival, benny gantz, said he would work towards a government of national unity. us officials say they've identified the exact locations in iran from which they believe an attack on saudi oilfacilities was launched on saturday. the broadcaster, cbs, says more than 20 drones and cruise missiles were fired. iran denies involvement in the attacks, which have disrupted global oil supplies. a landmark case has started in the uk supreme court — withjudges considering whether borisjohnson acted unlawfully in suspending parliament for 5 weeks. world leaders are meeting at the un

climate action summit in new york next week, to discuss how to cut global emissions, and the economic consequences of tackling climate change. for the first in a series of bbc briefings, in—depth investigations into the biggest issues facing the uk today, our business editor simon jack examines the challenges and opportunities of the drive for a zero—carbon economy. the uk's journey to a zero carbon future arguably started here, delabole in cornwall... they thought we were mad... ..where local farmer martin edwards built the uk's first commercial wind farm in 1991. nearly 30 years on, he says there is a genuine wind of change in the air. i think the political climate regarding renewable energy, or energy supply as a whole, has changed dramatically. people have really woken up to the idea that climate change is really real and really urgent. 10,000 turbines later,

the energy system is transformed. in 1990, coal and oil were dominant. in 2018, renewables made up a third, while coal has all but disappeared. you say low carbon, everyone cheers. you say nuclear, like this plant on the construction at hinkley point in somerset, some feel less comfortable. critics add it's big, it's slow, and at £20 billion, it's expensive. builders edf argue it's the perfect back—up when the wind doesn't blow. people who are furious about climate change really need to rethink nuclear. it's low carbon, it's safe and it can be made affordable, and if we are really, really serious about taking carbon out of the way we make electricity, then we need nuclear. and we're going to need a lot of electricity if we're going to replace petrol and diesel engines. it seems very odd looking under the bonnet and seeing nothing, really. you get used to it! nearby dealer in second hand electric vehicles andy farmer says business is brisk. the change has been huge.

it's gone from being more of a niche thing to now anyone‘s buying an electric car. for the school run, if two or three people get an ev, everyone starts to go, "wait, i could do that, i could live with an ev". despite a fivefold increase in sales over the last year, evs make up less than 1% of vehicles on the road and there's an even tougher, more expensive and less exciting challenge. so, here it is, good old —fashioned gas boiler. we all recognise that, there are 2a million of them around the uk and that is a big problem because they are one of the biggest sources of emissions. in fact, they churn out five times as much carbon as all uk aviation. we will need new heating systems, like hybrid electric pump. this looks suspiciously like an air conditioning unit. that's exactly what it is, but in reverse. russell williams, in bridgend, is part of a pilot scheme. now, i'm definitely not a co—warrior but i think if we can make a positive change, which doesn't affect our everyday living, that's always got to be a good thing. the bill for refitting

heating systems? £500 billion, out of a total of one trillion over the next 30 years to get to zero carbon. the vision is for zero carbon electricity to both power vehicles which double as batteries, while producing hydrogen to supplement heating systems for well insulated homes lived in by people who don't eat much meat and rarely get on an aeroplane. it is a gigantic economic and societal challenge for a country that, remember, producesjust1% of global emissions. however green and pleasant this land becomes, the net zero target doesn't include the carbon cost of things consumed here but made abroad. we have to set an example, it's just that we have to be brutally honest. 0ur example is about our spending, our consumption and our u nsusta i na ble lifestyle. it's not some technical fix or some nasty company we can just tell to behave itself. as the nation that ushered in the industrial revolution, maybe we have a responsibility to lead a green revolution.

in the end, it may amount to a moral as much as an economic challenge. do we want to be part of the problem, or part of the solution? simon jack, bbc news. and for more facts and analysis about climate and energy, and to download our new in—depth energy briefing, you can go go to bbc.co.uk/energy. now on bbc news, our world. bell tolls. knocking. 00:07:08,276 --> 4294966103:13:29,430 singing.
