Zimbabwe's worsening electricity shortages mean power is often only available for a few hours in the middle of the night - forcing furniture maker Richard Benhura to start work at 23:00.It is just one aspect of the country's dire economic difficulties as official inflation nears 100% and supplies of daily essentials such as bread and petrol regularly run short."If you want to work, you have to be here overnight and start when the electricity comes on until it goes off around 4:00 am," Benhura, 32, told AFP as he made some wooden backrests for chairs.At the open-air Glen View furniture market in Harare, Benhura welds steel frames for chairs and grinds off rough edges in the darkness, and then returns to do his manual woodwork in the daylight.Zimbabwe - where the economy has recently lurched into a fresh crisis - introduced rotational power cuts of up to 19 hours a day earlier this year, forcing many to do their ironing or cooking in the dead of night.For Egenia Chiwashira, a resident of the poor Harare suburb of Mbare, the outages are a grim burden.The mother of three in her 40s says she can barely afford to feed her family, let alone pay for a generator.'We are in darkness'"To cook porridge for my children needs electricity, also for me to prepare myself something to eat," Chiwashira said, while stoking a fire she had made outside her house to prepare supper."We are always in darkness. It's not easy. Life in the city is tough without electricity.

"We only got supplies back on Monday afternoon."Energy minister Fortune Chasi has pledged the outages would be reduced, and urged consumers to pay their bills to enable ZESA to buy more power from neighbouring countries."We will be turning the corner pretty soon," Chasi told a post-Cabinet briefing this week, adding that ZESA had just paid a $20-million debt to neighbouring South Africa.South Africa's state-owned energy company Eskom on Friday denied the money had been paid.No post-Mugabe upturnOne of few to see an improvement in business is Simba Vuremu, a stationery shop owner who has added solar lighting units to his stock."They are selling and selling fast," he said.After Robert Mugabe was ousted from power in 2017, many Zimbabweans hoped that their country's long economic decline would be reversed under his successor President Emmerson Mnangagwa.A young Zimbabwean boy does his homework under a candle light in Harare.

We have got a problem."
