Policymakers seeking to velocity up renewable vitality deployment have a best-practice case research to look to: Australia is rolling out renewables 10 instances sooner than the worldwide common, providing classes as to what components can enhance the uptake of fresh vitality.

A RenewEconomy evaluation of Worldwide Renewable Power Company (IRENA) figures for 2019 exhibits Australia’s per-capita deployment charge was additionally 4 instances increased than fast-developing renewable markets similar to China, Europe, Japan and the U.S.

When it comes to general capability, Oceania nonetheless solely accounts for a tiny share of worldwide renewables. Its 40 gigawatts of renewables amounted to only 2 % of fresh vitality worldwide in 2019, IRENA figures present. However it added 6.2 gigawatts of capability final yr, rising greater than 18 %. That compares to six % development in North America, 7 % development in Europe, and 9 % in Asia.

Australia’s modest inhabitants of 25 million means per-capita development charges are much more excessive.

Whereas Australia has a vibrant wind market, distributed photo voltaic has been the true success story, stated Darren Miller, CEO of the Australian Renewable Power Company. “Wind has been a baseline. At the same time as states have eliminated feed-in tariffs, photo voltaic rooftop set up charges have grown to file ranges,” Miller stated in an interview.

A mixture of pure benefits and sensible policymaking have pushed the Australian photo voltaic market. Round 10 years in the past, Australia’s state governments launched feed-in tariffs and federal authorities introduced in rebates for photo voltaic techniques. The latter nonetheless present roughly one-third off upfront prices.

For the final 5 years or so, the rooftop PV market has been boosted by rising electrical energy prices, a development that coincided virtually completely with a sustained discount in residential PV system costs. 

The nation advantages from numerous sunshine and excessive ranges of dwelling possession and single-dwelling bulidings. It additionally has a excessive per-capita gross home product, Miller stated, with wealth unfold pretty evenly throughout the inhabitants, making a rooftop PV system an actual possibility for a big fraction of the inhabitants.

The recipe is working. Based on a Q1 2020 photo voltaic report from the Australian Power Council, virtually 2.four million photo voltaic techniques have been put in throughout the nation. Australia’s rooftop PV capability provides as much as 10.7 gigawatts, or three-fifths of the 17.6-gigawatt U.S. residential photo voltaic market, for a rustic that has lower than eight % of America’s inhabitants.

Rocketing residential photo voltaic adoption in Australia has helped stimulate the industrial, industrial and utility-scale markets, Miller stated.

The ‘secrets and techniques’ behind Australia’s photo voltaic success

One other essential issue serving to to spice up photo voltaic uptake in Australia is the shortage of pink tape regarding installations, Miller stated. “There’s little or no by way of council approvals, authorities approvals and the like. It may be performed by an electrician.”

That mild regulatory contact helps to maintain costs down. Residential photo voltaic techniques are at the moment priced at about AUD $1 (about 70 cents U.S.) per watt in Australia, together with set up, Miller stated. That compares to USD $2.69 per watt within the U.S., in response to 2020 estimates from Wooden Mackenzie for the Photo voltaic Power Industries Affiliation.

Not each nation can have Australia’s sunshine, however that may not be all that essential in the long term, stated Fereidoon Sioshansi, president of Menlo Power Economics in California. 

“The quantity of sunshine helps, however has little to do with it,” Sioshani defined in an e mail, pointing to different, more-important components, similar to supportive laws, the proportion of single-family houses and excessive retail electrical energy costs. 

Taking a look at profitable photo voltaic markets, “it’s essential for customers to get rewarded for exporting extra photo voltaic, a minimum of to start with,” Sioshansi stated.

There are a number of classes the U.S. may study from Australia, stated Lauren Shwisberg, a supervisor in Rocky Mountain Institute’s electrical energy apply. They embrace simplifying rooftop photo voltaic incentives and making it simpler to arrange digital energy crops.

Different elements of Australia’s booming photo voltaic market is perhaps more durable to emulate. “The U.S. has comparatively cheaper retail charges for electrical energy, so there’s much less incentive for buyer adoption based mostly on particular person worth proposition,” Shwisberg stated.

“We’ll must get artistic within the U.S. if we wish to see buyer adoption take off and supply clients with further worth.”
