1979年，當全世界都在為冷戰和能源危機焦頭爛額時，康奈爾大學的三位研究人員正忙著測量煮一顆中等大小的雞蛋需要多少瓦時
研究結果狠狠地打臉了西方「大即是好」的哲學。例如，研究發現用標準烤箱「焗蛋」簡直是一場能源災難，竟然需要高達 564 瓦時的能量——而這些能量大部分只是用來加熱空氣和烤箱厚重的金屬壁
與此同時，硬殼蛋的「冷水啟動法」則是終極的生存主義智慧。先將水燒開，然後直接「關火」讓蛋在熱水中靜置 25 分鐘，只需消耗 136 瓦時，遠低於傳統沸水啟動法的 183 瓦時
最令人心碎的真相莫過於微波爐。這個被包裝成效率巔峰的神器，在炒蛋時消耗的電能（75-80 瓦時）實際上比簡陋的瓦斯爐頂層加熱法（68-73 瓦時）還要多
The UK's housing and energy crisis, rooted in its inefficient building stock, requires not only a shift in housing strategy but also a fundamental change in the business model of energy companies. While building modern, energy-efficient homes is a long-term goal, immediate action is needed to tackle the existing inefficiency. A significant barrier to this is the current revenue model of energy suppliers, which directly conflicts with the goals of energy conservation. This paper argues for a change in how energy companies are measured and compensated, proposing a system where their profitability is linked to reducing energy consumption, not increasing it.
Currently, energy companies generate revenue and profit by selling units of gas and electricity (measured in kilowatt-hours, or kWh). The more energy their customers consume, the higher their sales and, consequently, their profits. This creates a powerful disincentive for companies to actively promote or invest in energy efficiency measures, such as home insulation upgrades, smart meter installations, or more efficient heating systems.
While some companies may participate in government-mandated efficiency schemes, their core business interest remains tied to consumption. This inherent conflict of interest means that even with good intentions, the system is designed to perpetuate the very problem it claims to solve: high energy use, high bills, and high carbon emissions. The government's efforts to subsidize bills and fund efficiency programs are merely treating the symptoms, not the underlying cause of this market failure.
To realign incentives, we must change the metric of success for energy companies from units sold to units saved. The government should introduce a regulatory framework that allows and encourages energy suppliers to profit from their customers' energy reductions.
This can be achieved by:
Setting a Baseline: For each household or business, a baseline of energy consumption would be established based on historical data. This baseline would serve as the starting point for measuring efficiency gains.
Performance-Based Compensation: Energy companies would be granted a guaranteed profit margin on the energy they supply, but they would also be compensated for every unit of energy their customers save below the baseline. For example, if a home's average consumption is 10,000 kWh per year and the energy company helps them reduce it to 8,000 kWh, the company would receive a pre-determined payment for the 2,000 kWh saved.
Third-Party Verification: Independent auditors would verify the reductions to prevent fraud and ensure accurate reporting. This would guarantee that energy companies are genuinely helping their customers save energy.
This model transforms energy companies from simple commodity sellers into energy service partners.
This proposal offers a workable and reasonable path to solving the crisis. It benefits all parties:
For Consumers: Lower energy bills and more comfortable homes, without having to navigate complex government grant schemes on their own.
For Energy Companies: A stable and predictable revenue stream that is less vulnerable to market volatility. They can become true partners in the energy transition.
For the UK Government: A significant reduction in the need for costly bill subsidies, a major step toward net-zero emissions, and enhanced energy security through reduced import dependency.
By changing the rules of the game, we can transform the energy crisis from a problem to an opportunity, turning the biggest players in the market into the most powerful allies for a sustainable future.
The United Kingdom is grappling with a multi-faceted crisis encompassing housing shortages, exorbitant energy costs, and an urgent need to meet net-zero emissions targets. While these issues may seem distinct, their root cause is interconnected: the nation's aging and poorly insulated housing stock. A significant percentage of UK homes, particularly those built before 1980, are energy inefficient, leading to massive heat loss, high utility bills, and a dependency on foreign energy imports. The country's reluctance to abandon its traditional, often aesthetically cherished, housing for modern, efficient alternatives exacerbates this crisis.
The UK's housing market is defined by its age. Over 40% of the homes were built before 1944, and a staggering 70% were constructed before 1980. While charming in appearance, these older homes were built without modern insulation standards. They feature single-pane windows, thin walls, and a lack of proper sealing, making them a thermal sieve. This inefficiency forces households to consume significantly more energy—primarily natural gas for heating—to maintain a comfortable temperature. This direct link between poor insulation and high energy consumption is a core driver of the cost-of-living crisis.
The consequences of this energy inefficiency are severe and widespread. At the household level, families face crippling energy bills, pushing many into fuel poverty. The government, in turn, is forced to provide billions of pounds in subsidies and support programs to mitigate these costs, adding a significant burden to public finances.
On a national scale, the UK's dependence on imported natural gas and oil leaves it vulnerable to volatile international energy markets, as evidenced by the recent price spikes. This dependency not only drains the national economy but also undermines energy security. Furthermore, residential heating is a major source of carbon emissions. The poor energy performance of the housing stock directly obstructs the UK's legally binding commitment to achieve net-zero emissions by 2050.
The solution to this crisis lies in a fundamental change in housing strategy. Instead of preserving inefficient older homes, the UK should prioritize the construction of high-density, energy-efficient tower blocks in urban centers. These modern buildings can be designed with superior insulation, double or triple-glazed windows, and integrated renewable energy systems (like solar panels and heat pumps), drastically reducing their energy footprint.
Building upwards in city centers would address the housing shortage by creating thousands of new homes on a smaller land area. It would also reduce the need for commuting, as residents would be closer to workplaces, further cutting down on emissions. The energy savings from such a shift would alleviate household financial strain, reduce the government's subsidy expenditure, and decrease reliance on energy imports. While the aesthetic and cultural value of traditional homes is undeniable, the economic and environmental costs of maintaining them are no longer sustainable.
