Australian Renters Stand to Save $20 Billion Through Energy Upgrades, but Landlord Inaction Remains the Key Obstacle

澳洲租客有望透過能源升級節省 200 億美元，但房東的不作為仍是主要障礙

Australian renters, who constitute nearly one-third of all households, could collectively save an estimated $20 billion on energy bills over the next decade.

佔所有家庭近三分之一的澳洲租客，在未來十年內總計可節省估計 200 億美元的能源費用。

However, this projection hinges on whether landlords are willing to invest in rooftop solar installations, insulation, and efficient appliance upgrades across rental properties.

然而，這項預測取決於房東是否願意在租賃物業中投資屋頂太陽能設施、隔熱材料以及高效能家電更新。

A comprehensive analysis by the Institute for Energy Economics and Financial Analysis has identified the so-called split incentive as the primary barrier to progress.

能源經濟與財務分析研究所的一項全面分析已將所謂的「拆分激勵」確定為進步的主要障礙。

The split incentive, a well-documented concept in behavioral economics, arises when the party responsible for funding improvements differs from the one reaping the benefits.

「分配不均的誘因」是一個在行為經濟學中被廣泛記錄的概念，當負責出資改善的一方與獲得收益的一方不同時，這種現象就會產生。

In the context of rental properties, landlords bear the capital costs of energy efficiency upgrades, yet it is tenants who enjoy the resulting reduction in utility expenses.

在租賃物業的背景下，房東承擔能源效率升級的資本成本，然而享受隨之而來的公用事業費用減少的卻是租客。

Energy finance analyst Jay Gordon emphasized that this misalignment effectively eliminates any financial motivation for property owners to act.

能源金融分析師傑伊·戈登強調，這種錯位實際上消除了房東採取行動的任何財務動機。

The disparity in solar adoption rates starkly illustrates this dynamic.

太陽能採用率的差異鮮明地說明了這種動態關係。

Research from Energy Consumers Australia revealed that 44 percent of owner-occupiers had installed solar panels, compared with a mere 11 percent of rented homes.

澳洲能源消費者協會的研究顯示，有 44% 的自住業主已安裝太陽能板，而租賃房屋的比例僅為 11%。

Were landlords to undertake these upgrades, the benefits would extend well beyond individual savings.

倘若房東著手進行這些升級，其效益將遠遠超出個人所節省的開支。

The modeling suggested that in the vast majority of scenarios, a combination of insulation, efficient appliances, and rooftop solar could halve a household's energy expenditure.

模型分析顯示，在絕大多數情況下，隔熱設備、高效能家電和屋頂太陽能的組合可以使家庭能源支出減半。

Looking further ahead, the cumulative savings for Australian renters could reach $107 billion by 2050, substantially outweighing the initial capital investment required.

展望未來，澳洲租客的累計節省金額到 2050 年可能達到 1070 億美元，大大超過了最初所需的資本投資。

These figures carry significant implications for climate policy and carbon reduction targets, given that residential energy consumption accounts for a considerable share of national emissions.

鑑於住宅能源消耗在國家排放中佔有相當大的比例，這些數據對氣候政策和減碳目標具有重大意義。

Analysts have argued that without targeted regulation compelling landlords to meet minimum energy performance standards, the split incentive will persist indefinitely, leaving millions of tenants to shoulder unnecessarily high costs.

分析師指出，若缺乏強制房東達到最低能源績效標準的針對性法規，拆分激勵問題將無限期持續，導致數百萬租客必須承擔不必要的高昂成本。
