Internet - Economic Commercial and Environmental Impact

Online Advertising, E-Commerce, and the Internet's Societal Impact Introduction The internet has fundamentally transformed how businesses operate and market to consumers. This material covers three interconnected topics: the mechanisms and practices of online business, the technologies that power modern websites, and the broader environmental and social consequences of internet use at scale. Online Advertising What Is Online Advertising? Online advertising is the delivery of promotional marketing messages to consumers via the Internet. Unlike traditional advertising, it leverages digital platforms to reach specific audiences with targeted messages. Common Types of Online Advertising The primary forms of online advertising include: Email marketing: Sending promotional messages directly to customers' email inboxes Search engine marketing: Displaying ads alongside search results on platforms like Google Social media marketing: Promoting products or services on social media platforms Web banner advertising: Displaying visual ads on websites Mobile advertising: Targeting users on smartphones and tablets Each method allows advertisers to customize messages, track user responses, and reach audiences with varying degrees of precision. Controversial Practices and Regulation Many online advertising practices raise ethical and privacy concerns. For example, targeted advertising often relies on collecting detailed information about users' browsing habits, location, and interests. As these practices have become more sophisticated and widespread, governments have responded with increasing regulation. Knowing that regulations exist around online advertising is important context for understanding how internet commerce operates. E-Commerce and E-Business Defining E-Commerce E-commerce is the sale of products and services directly via the Web. This includes everything from retail sales on Amazon to digital downloads to subscription-based services. E-commerce has grown substantially and continues to expand, fundamentally changing how consumers shop. Understanding E-Business Electronic business (e-business) is a broader concept than e-commerce. While e-commerce focuses specifically on buying and selling, e-business encompasses all digital processes across a company's entire value chain, including: Purchasing and procurement Supply chain management Marketing and advertising Sales transactions Customer service Business relationships with partners and vendors In other words, e-business is the complete transformation of business operations to leverage digital technology, whereas e-commerce is the commercial sales component of that transformation. Web Development and Content Management Dynamic Web Page Creation Modern websites are no longer static documents. Instead, dynamic web pages are created on-the-fly based on user requests, database queries, and other conditions. This means that a single web page template can display different content to different users or at different times, allowing for flexible design, personalized layout, and customized content. This is fundamentally different from early websites, which consisted of fixed HTML files that displayed the same content to everyone. Content Management Systems (CMS) Most websites today are built using content management software (CMS)—platforms that separate content from presentation. With a CMS: Content (articles, product information, images) is stored in a database The website's design and layout are handled separately Website administrators can update content without needing to edit HTML code directly Popular examples include WordPress, Drupal, and Joomla. This approach makes it much easier to maintain and update websites at scale, which is why most modern websites rely on CMS platforms. Societal and Economic Impacts of Internet Commerce Economic Inequality and the Digital Divide Internet-enabled services such as maps and location-aware applications create new opportunities for consumers who have access to reliable internet service. However, these same services can reinforce economic inequality and the digital divide—the gap between those with access to internet technology and those without. People without reliable broadband access may lack access to important services, job opportunities, and price comparison tools that internet users take for granted. Impact on Brick-and-Mortar Retailers Electronic commerce has accelerated the decline of traditional brick-and-mortar retail stores, particularly small, independent retailers. Large e-commerce platforms like Amazon can undercut local prices through economies of scale and avoid some local tax burdens, making it difficult for local shops to compete. This shift has contributed to increased income inequality because: Job losses in retail sector, which traditionally employed workers with varied skill levels Concentration of wealth and employment opportunities among large tech companies Reduced economic activity in communities that relied on local retail Energy Consumption and Environmental Impact of the Internet Understanding the Challenge of Measurement Calculating the internet's total energy use is surprisingly difficult. A 2014 peer-reviewed study found that published estimates of internet electricity consumption differed by a factor of 20,000, ranging from: Low estimate: 0.0064 kilowatt-hours per gigabyte transferred High estimate: 136 kilowatt-hours per gigabyte transferred Why such enormous discrepancies? The main factors were: Reference year used: Earlier estimates didn't account for efficiency improvements in data center hardware and networking equipment. As technology has improved, less energy is needed per unit of data transfer. Scope of what's included: Some estimates counted only data center operations, while others included manufacturing and periodic replacement of all end-user devices (laptops, smartphones) and infrastructure equipment (routers, cell towers, servers, Wi-Fi transmitters). This is a crucial lesson: when you see energy statistics, always ask what's being measured and what time period is involved. Overall Internet Energy Consumption Despite the measurement challenges, researchers have produced estimates of total internet energy use. In 2011, researchers estimated that the internet's total energy consumption was: Between 170 and 307 gigawatts Less than 2 percent of global energy consumption This estimate includes energy for: Manufacturing, operating, and replacing approximately 750 million laptops Manufacturing, operating, and replacing approximately one billion smartphones Manufacturing, operating, and replacing approximately 100 million servers Operating routers, cell towers, optical switches, Wi-Fi transmitters, and cloud storage devices Carbon Emissions from Data Transfer and Video Streaming A 2018 study by The Shift Project (a non-peer-reviewed analysis) provided more specific findings about the internet's carbon footprint: 4 percent of global carbon dioxide emissions were attributed to global data transfer and its supporting infrastructure Online video streaming accounts for 60 percent of all data transfer, generating over 300 million tons of carbon dioxide emissions annually This finding is significant because it identifies video streaming as the dominant source of internet-related emissions. The authors advocated for "digital sobriety" regulations that would limit the size and quality of video files transmitted online, similar to how some regions have reduced energy use through efficiency standards. Key Takeaway on Internet Energy The internet's energy consumption is substantial, but it's often misunderstood or overstated in popular media. The critical points to remember are: Estimates vary widely depending on methodology and scope Efficiency has improved significantly over time Video streaming is the largest individual contributor to internet carbon emissions As a global percentage, internet energy use is significant but not dominant Social and Political Impact: The Arab Spring Social Media's Role in Political Mobilization The Arab Spring (2010-2012) provided a striking demonstration of the internet's power to facilitate social and political change. Online platforms, particularly social media, enabled: Rapid mass mobilization: Organizers could reach thousands of people quickly to coordinate protests and demonstrations Cross-border coordination: Political movements could share strategies, resources, and inspiration across national boundaries Circumventing traditional media: Activists could spread messages directly to populations without relying on government-controlled news outlets The Arab Spring demonstrated that social media and internet platforms are not neutral tools—they actively shape political possibilities by enabling communication at massive scales. However, this also highlighted that the same platforms that enable grassroots movements can be used for surveillance and control by authorities.
