Conservation Through Engineering Extract from the Annual Report of the Secretary of the Interior

In the early 1920s an urgent crisis erupted when a nationwide coal strike threatened to plunge the United States into darkness. From the desk of the Secretary of the Interior, this report unpacks the startling reliance on a single fuel source, asking plain‑faced questions about how much coal is produced, who mines it, and what it powers. The opening chapters paint a vivid picture of factories stilled, railroads idle, and families facing freezing homes, while also revealing the flood of public debate over labor rights, government responsibility, and the danger of putting society at the mercy of a thin supply.

Lane argues that engineering—rather than mere legislation—holds the key to safeguarding the nation’s energy future. He surveys emerging technologies from diesel engines to oil‑shale processing, and proposes a coordinated program linking engineers, legislators, and business leaders to conserve existing fuels while developing new sources. The tone is pragmatic yet forward‑looking, inviting listeners to consider how the challenges of a century‑old strike still echo in today’s debates over sustainable power.
