The Power of Black: From Gen Z Fashion to Digital Sustainability
Introduction: More Than Just a Color
The obsession that most Gen Z has with the color black is for real! It is a dominant trend in fashion, design, and lifestyle. Black is often used as a symbol of mystery, elegance, and nonconformity, which may resonate with the independent and individualistic values of many young people. However, are you aware of some of the scientific properties of the color black? Beyond its aesthetic appeal, black color absorbs most of the heat and radiates less amount of heat energy. Throughout history, many scientific discoveries and advancements have been made possible by the application of this unique property.
One such advancement is the creation of Blackle – The black Google. This innovative tool bridges the gap between a simple color preference and global energy conservation.
The Birth of Blackle: A Sustainable Alternative
In January 2007, Heap Media, an Australian Internet company based in Sydney, launched Blackle. This launch was inspired by a pivotal moment in environmental blogging. Previously, an environmental blog called Treehugger.com had published a paper titled ‘Black Google Would Save 750 Megawatt-hours a Year’. Consequently, the creators saw an opportunity to turn this theory into reality.
Blackle is a search engine that claims to save energy by displaying search results on a black background instead of a white background, which is the default for most search engines. The primary goal was simple yet ambitious: to reduce the energy consumption of millions of computer screens around the world, one search at a time.
The Science Behind Blackle: Understanding Energy Consumption
To understand the impact of Blackle, we must first look at the physics of screen display. The idea behind Blackle is simple to understand. On older monitor technologies, a white color radiates more light and essentially requires more energy to produce, whereas a black color radiates less. In the context of energy use, white color radiates more and absorbs less heat energy. This will cause higher heat generation, leading to an increase in the carbon footprint of the device. Therefore, using a black background can theoretically reduce energy consumption and help to reduce carbon emissions.
While Blackle’s energy-saving claims have been debated over the years, it is true that using a search engine like Blackle can help to reduce your digital footprint. This is because every time you conduct a search, your computer sends a request to a server, which then sends back the results. This process requires energy and generates carbon emissions, as servers and data centers consume a significant amount of electricity. By using a search engine like Blackle, you can help to minimize the amount of energy and carbon emissions associated with your online activities.
However, it’s important to keep in mind that the impact of individual actions like using a specific search engine may be relatively small. Reducing your overall digital footprint may require more significant changes to your online habits and behaviors. Nevertheless, every small step counts in the grand scheme of sustainability.
How Blackle Makes the Difference: The Numbers Game
Blackle makes a difference by offering a sustainable alternative to traditional search engines and by raising awareness about the importance of reducing our energy consumption and carbon footprint. But how much energy does it actually save?
In the influential paper, ‘Black Google Would Save 750 Megawatt-hours a Year’, the authors provided a fascinating breakdown of the math. They noted that:
“Google gets about 200 million queries a day. Assuming each query is displayed for about 10 seconds, means Google is running for about 550,000 hours every day on some desktop. Assuming that users run Google in full screen mode, the shift to a black background [on a CRT monitor!] will save a total of 15 (74-59) watts. That turns into a global savings of 8.3 Megawatt-hours per day, or about 3000 Megawatt-hours a year. Now take into account that about 25 percent of the monitors in the world are CRTs, and at 10 cents a kilowatt-hour, that’s $75,000, a goodly amount of energy and dollars for changing a few color codes.”
The point to be noted here is that this blog was published in the year 2007, which was during the CRT (Cathode Ray Tube) era. During the 2000s, desktop computer displays were made with the use of CRTs. It is similar to the “picture tube” in a television receiver. However, CRT screens are no longer as commonly used as they once were. CRTs have now largely been replaced by LCD (Liquid Crystal Display) screens. This technological shift plays a crucial role in how effective Blackle is today.
Blackle vs. Google: A Comparative Look
When comparing the two search engines, several distinct differences arise.
User Interface and Design
The first difference has to be about the User Interface. Blackle uses a stark black Interface, creating a dark mode aesthetic long before it was a standard feature. On the other hand, Google uses the classic white Interface we are all familiar with.
Features and Functionality
In terms of features, there is a clear disparity. Blackle is a basic search engine with limited features. It does the job of searching, but not much else. However, Google has evolved into a tech giant with features like personalized search, voice search, Google Maps, and integrated shopping tools.
Ownership and Market Share
Furthermore, the ownership differs. Google is owned by Alphabet Inc., a multinational conglomerate. In contrast, Blackle is owned by Heap Media, a small Australian company. We cannot deny the fact that Google is by far the most popular search engine, with over 90-92% of the global search engine market share. Conversely, Blackle has a very small user base, catering mostly to environmentally conscious netizens.

Drawbacks of Blackle: The Thorns in the Rose
And I need not mention that as every rose has its own thorn. Just like that, the use of Blackle as a search engine with a black background has its negative aspects too. Many netizens have raised counter-arguments that suggest Blackle may have little to no significance in terms of saving power in the modern age.
The CRT vs. LCD Problem
The primary drawback is the technology shift mentioned earlier. The energy-saving benefits of using a black background on computer monitors may only apply to a specific type of monitor: the CRT. Currently, CRTs account for only 20% or less of screens globally. In the era of LCDs, CRT-based monitors are virtually a dead technology.
For newer thin LCD monitors, using a black background may not result in any major energy savings. This is because LCD monitors work by using a backlight that is always on behind the liquid crystals; the crystals twist to block the light (showing black), but the backlight itself remains powered. Therefore, the energy consumption difference between displaying white and black on an LCD is negligible.
Duration of Use
Furthermore, the potential energy savings from using a black background may only occur for short periods of time. Users often quickly find the page they are looking for and leave the black background. The few seconds spent on the search results page might not add up to significant energy conservation for the average LCD user.
Conclusion: A Step Towards a Greener Mindset
Despite the technological limitations regarding LCD screens, Blackle’s focus on energy conservation and sustainability remains relevant in today’s era. The need for sustainable practices is more important than ever. Blackle’s energy-saving approach is still applicable to modern technology, including some screens, but more importantly, it serves as a symbol.
It may not be as effective as it was for CRT, but by using a dark background, Blackle can still help to reduce the amount of energy consumed by electronic devices, including computers, smartphones, and tablets, particularly those using OLED or AMOLED screens where black pixels are indeed turned off. Although the energy savings achieved through Blackle may appear modest on an individual level, when multiplied by millions of users across the globe, it can make a considerable difference in reducing the overall carbon footprint.
Moreover, the frequent use of Blackle as the default search engine serves as a reminder to individuals to be mindful of their energy consumption. It encourages them to take additional steps towards sustainability. By adopting Blackle, individuals can contribute towards a more sustainable future, one small step at a time.
