Concerning the text above and previous knowledge, judge the
item from
China has charged ahead with a bold effort to remake the way that government-backed money works, rolling out its own digital currency with different qualities than cash or digital deposits. The country’s central bank started testing a new electronic currency, which was named electronic Chinese yuan or eCNY, last year in four cities and have recently expanded those trials to bigger cities such as Beijing and Shanghai, according to government presentations. No other major power is as far along with a homegrown digital currency.
The effort is one of several by central banks around the world to try new forms of digital money that can move faster and give even the most disadvantaged people access to online financial tools. Digital currencies created by central banks give governments more of a financial grip. These currencies can enable direct handouts of money that expire if not used by a particular date and can make it easier for governments to track financial transactions to stamp out tax evasion and crack down on dissidents.
If the eCNY is successful, it will give the central bank new powers, including novel types of monetary policy to help the economy grow. In one possibility that economists have discussed, a central bank could program its digital currency to slowly lose value so that consumers are encouraged to spend it immediately. Also, the eCNY could immediately give the Chinese government more power to monitor finance flows because a digital currency system can record every transaction.

The Pros and Cons of Nuclear Power
Since the disaster at the Fukushima nuclear power plant in Japan in 2011, a debate has been raging (1) the future of atomic energy. Consequently, the safety risks have been well publicized in the global media. But do the risks outweigh the damage that could be done to the planet because of our ongoing addiction to fossil fuels?
Even environmentalists don’t have the answer. They are split over nuclear (2) , and its pros and cons. Some say it is neither safe nor economical because it produces potentially (3) radioactive waste, and reactors are so costly to build. However, others believe nuclear energy is a necessary evil. They say we should continue using it until (4) energy sources, like wind turbines and solar panels, can meet global demand. Supporters also argue that nuclear energy helps cut down on carbon emissions from fossil fuels such as coal and natural gas, which are linked to global warming and pollute the environment. They say this is because nuclear reactors produce a tiny fraction of the carbon dioxide generated by burning coal.
But perhaps the biggest hurdle for atomic energy to overcome is its image problem. Despite industry claims of a strong safety record, critics remain unconvinced because each reactor annually produces up to 30 tons of nuclear waste, which can continue to be radioactive and hazardous for thousands of years. Furthermore, the Chernobyl disaster in 1986 left the public with vivid images of the impact of a nuclear meltdown, including deformed babies, mutated vegetables, and abandoned towns.
While nuclear reactors may continue to be installed in some countries for decades to come, after Fukushima others have decided to rethink their energy policies. For example, the German government has revealed plans for a “green” renewable energy plan, even though it has relied on nuclear power for up to 23 percent of its consumption in the past. It has been announced that all seventeen nuclear power plants would be phased out by 2022. The policy will also promote energy-saving measures encouraging people to insulate their homes, recycle, and reduce waste. Experts argue it could be a risky strategy because Germany doesn’t have natural gas or oil supplies, and coal supplies have been depleted.
Meanwhile, in Brazil, there is just one nuclear plant at Angra dos Reis. Nuclear power represents only three per cent of Brazil’s energy production. After sharp oil price rises in the 1970s, the country’s leaders anticipated future energy supply problems. So they concentrated on developing alternative energy sources including biofuel, hydroelectric schemes, and wind power.
This approach seems to be working because by May
2012 plans to build more nuclear reactors were shelved by Brazilian officials. The move was welcomed
by environmental lobby groups, which had feared a
potential ecological catastrophe in case of an accident. If a big country like Brazil, which is the tenth
largest energy consumer in the world, can survive and
improve its economy without much nuclear power,
maybe others can do so, too.
