Can a country live on renewable energy alone?
The Inquiry
Nov 17, 2022

The International Energy Agency says that the world is in the middle of the first global energy crisis. The price of natural gas has increased almost five-fold since the summer of 2020, and the main cause is Russia’s invasion of Ukraine. Moscow has cut supplies of gas to European countries that oppose the war, causing the wholesale price to shoot up everywhere.

Many countries have turned to coal to fuel their power stations, also causing prices to triple in the last year. But as well as being expensive, coal is also the most polluting fossil fuel. The situation has accelerated the push towards renewables, but can they provide the all the power needed by a country – as well as providing energy security? So this week on the Inquiry, we ask: can a country live on renewable energy alone?

Can the New World Screwworm be stopped?

Flesh-eating parasitic flies have been found in the US state of Texas for the first time in decades. Known as the New World Screwworm, officials have now put plans in place to try and contain its spread. The fly feeds off warm-blooded animals, like cattle, dogs and horses, but if detected early enough, with treatment, the animals can make a full recovery. It can also infest humans, but human deaths are rare and it poses no food safety issues.

The New World Screwworm is not a new problem; it is considered endemic in South America and some parts of Central America, towards South America. But despite the United States declaring itself screwworm free in the 1960s, the country has since seen several outbreaks. Officials have been tracking this latest case since late 2024.

To date, the most widely used method to try and control the spread of the screwworm is the Sterile Insect Technique, whereby millions of flies are hatched and exposed to radiation, before they are released into the wild. And the idea here is that as the females only mate once in a lifetime, any eggs they lay will be unfertilised and will not hatch. There is currently only one facility hatching these flies in operation and there are not enough sterile flies being produced. In addition, there is a concern over a lack of knowledge among new veterinary recruits on how to deal with a problem that many may be experiencing for the first time.

So, on The Inquiry this week, we’re asking ‘Can the New World Screwworm be stopped?’

Is technology ruining sport?

This year, technology has more influence in officiating sports than ever before.

At the men's World Cup, the role of virtual assistant referee technology (VAR) has been extended to include two more on-pitch scenarios while in tennis, umpires use electric line calling systems (ELC) to make final decisions.

Both bits of kit aim to improve the accuracy. It’s become easier to consider match-defining moments through these tracking and review systems’ specialised cameras. But, this information takes human officials valuable time to analyse.

Football fans criticise VAR for this reason, saying it delays match momentum. Top ranking tennis players Aryna Sabalenka and Alexander Zverev have also complained as these systems are not yet infallible. If technology is as imperfect as a human referee or umpire and can interrupt the fan experience too, why do elite sports rely on it?

We speak to Carlo de Marchis, independent adviser in sports and media technology in Italy; Dr Otto Koblinger, former sports scientist, Munich Technical University, Germany and senior data manager, Saudi Pro League; Professor Odilon Roble, sport philosopher and psychoanalyst, University of Campinas (UNICAMP), Brazil and Matt Moore, associate dean, University of Kentucky’s college of social work, US.
