“The biggest barrier to nuclear power in Australia is that it is uneconomic, the costs of establishing a nuclear industry simply don’t stack up,” the Australia Institute’s climate and energy program director Richie Merzian said.“Insurance policies by Australia’s major insurers contain specific language excluding coverage of nuclear disasters; none will insure against nuclear incidents.”The think tank has released its latest assessment of the prospects of an Australian nuclear industry ahead of its appearance before a parliamentary inquiry in Canberra. The research found that the cost of nuclear power is increasing and that recent experience has shown nuclear projects slow to construct and that adoption is falling in some countries.
Alternative Energy Sources
We may no longer have Paris, but we have Minneapolis and 64 other cities in the U.S. The nation's withdrawal from the Paris Climate Accord notwithstanding, politicians across the United States are expressing their commitment to renewable energy. In late April, for example, Minneapolis became the 65th city to announce its intent to transition to 100% clean energy, aspiring to complete the transition by 2030. According to the Sierra Club, five cities, including Aspen, Colorado, and Burlington, Vermont, have already achieved their goal of transitioning to 100% renewable energy.
The Australia Institute pointed to the fact that cheaper renewable energy technologies and the rapid falls in the costs of energy storage, meant there were alternative sources of zero-emissions electricity supply that made nuclear power unnecessary.
The report cited the example of the Hinkley C nuclear project in the United Kingdom , which as faced several delays and cost overruns while being expected to deliver electricity at a substantially higher price than renewable energy projects.“Renewables, demand management and storage can meet Australian energy needs safely and at best-cost. In a country with no existing nuclear industry and vast renewable energy resources, it makes no economic sense to establish nuclear generation,” Merzian added.
Nuclear Power Is Economically Obsolete
“A sensible, fact based conversation about nuclear power in Australia must start in economics, and given the industry’s dismal economic outlook, really that is where the conversation should end.”
The Australia Institute was also pessimistic about the potential for Small Modular Reactors (SMR) to be used in a viable nuclear project, finding that they suffer from ‘diseconomies’ of scale, and are likely to remain more expensive than zero-emissions alternatives until at least beyond 2040.In its submission to the nuclear inquiry, the Australian Energy Market Operator said that it believed it would take at least 15 years to get a Small Modular Reactor up and running in Australia.
The implication of this, AEMO said, was that nuclear power plants would only be a viable replacement for coal-fired power stations scheduled to close from around 2040 onwards, provided the economic and social acceptance challenges had been addressed.“Based on this timeline, SMR technology may be an option for consideration for the replacement of the Bayswater and Tarong power stations over the next 20 years,” AEMO said.AEMO also told the inquiry that a Small Modular Reactor would likely be substantially more expensive than renewables combined with storage.
Blowing away the competition. Coca-Cola and Burlington Northern Santa Fe may be two of Warren Buffett's most well-known investments, but the Oracle of Omaha also represents one of renewable energy's greatest advocates. MidAmerican Energy Company, a subsidiary of Berkshire Hathaway, has the long-term goal of providing 100% renewable energy to its customers. Illustrating its prominence in the renewable energy sector, MidAmerican claims on its website that "no other U.S. rate-regulated utility owns more wind-powered generation capacity." And the energy company shows no signs of slowing down its commitment: MidAmerican is currently constructing the 2,000 megawatt Wind XI project, which is expected to be completed in late 2019.
“The levelised cost of electricity (LCOE) in 2020 of, say, wind with 6 hours of pumped hydro storage as a representative firmed renewable, is in the range of 100 $/MWh, whereas the estimate for LCOE of SMR technology is $250 to more than $300 per MWh. SMRs could be almost three times more expensive than firmed renewables.” AEMO said.The nuclear power inquiry was criticised by the Clean Energy Council , which labelled it a ‘distraction’ from more pressing challenges facing the Australian energy market.
Renewable Energy Is The Future. It’s no secret that renewable energy holds the keys to our future success and potential survival. To combat global warming, we need to get away from traditional fuels like oil and coal. The final surprising statistic, however, is just how quickly renewable energy can make a difference. By 2050, renewable energy could meet up to 95% of our overall energy demands around the world. That means we could drastically reduce our global dependence on nonrenewable energy in just over 30 years. Interested in being a part of that solution?

“It is beyond our comprehension as to why Australia would contemplate replacing one dirty energy production technology with another that produces large amounts of highly hazardous waste, when it could fulfil its objectives of zero emissions with technologies that are lower-cost, faster to develop and readily available now,” the Clean Energy Council said in its submission to the inquiry.Nuclear power has long faced barriers in Australia including with lower social acceptance compared to other energy technologies and active opposition from environmental groups, notwithstanding current prohibitions under the Commonwealth Environment Protection and Biodiversity Conservation (EPBC) Act.
The Inquiry into the Prerequisites for Nuclear Energy in Australia was instigated in August by federal energy minster Angus Taylor following pressure from a backbenchers group led by Barnaby Joyce.While allowing the inquiry to go ahead, the Morrison Government has said that it has no plans to lift the prohibition of nuclear power activities under the EPBC Act.
