This chapter uses the cleantech bubble and bust of the 2000s as a case study in how not to build a company. Thiel identifies seven questions every business must answer, then shows how most cleantech companies failed by getting most or all of them wrong. Tesla stands as the exception that proves the rule.
The Cleantech Bubble
Between 2005 and 2009, billions of dollars poured into cleantech companies. Entrepreneurs, investors, and governments believed that renewable energy was the next big thing. But more than fifty solar manufacturers went bankrupt or shut down, and the sector destroyed enormous amounts of capital.
“Most cleantech companies crashed because they neglected one or more of the seven questions that every business must answer.”
— Peter Thiel
The failures were not caused by bad intentions or even by bad technology. They were caused by vague thinking, herd mentality, and a failure to ask the hard questions.
The Seven Questions Every Business Must Answer
Thiel distills the essential questions into a checklist. A great company must have good answers to all seven — or at least most of them. A company with zero good answers is doomed.
The Seven Questions
-
The Engineering Question: Can you create breakthrough technology instead of incremental improvements? (10x better, not 10% better)
-
The Timing Question: Is now the right time to start this particular business?
-
The Monopoly Question: Are you starting with a big share of a small market?
-
The People Question: Do you have the right team?
-
The Distribution Question: Do you have a way to not just create but deliver your product?
-
The Durability Question: Will your market position be defensible 10 and 20 years into the future?
-
The Secret Question: Have you identified a unique opportunity that others don’t see?
How Cleantech Failed Each Question
Thiel methodically shows how most cleantech companies failed the checklist.
Cleantech’s Failures
- Engineering: Most solar companies offered only incremental improvements over existing technology, not the 10x improvement needed to displace fossil fuels
- Timing: Companies assumed solar costs would drop quickly, but the timeline was much longer than expected. Chinese manufacturers undercut Western companies on price.
- Monopoly: Companies entered enormous markets with no plan to dominate even a small niche first
- People: Cleantech executives often looked and acted like corporate managers rather than missionaries. They wore suits to pitch meetings.
- Distribution: Many companies built products without any clear plan for getting them to customers
- Durability: Companies did not anticipate competition from Chinese manufacturing or from natural gas fracking
- Secret: Most cleantech companies shared a conventional view that “green is good” — not a genuine contrarian insight
Tesla: The Exception
Thiel holds up Tesla as the company that got all seven questions right. While dozens of solar companies failed, Tesla built a durable monopoly in electric vehicles.
How Tesla Answered the Seven Questions
- Engineering: Tesla’s technology was so good that other car companies relied on it (e.g., Daimler and Toyota used Tesla battery packs)
- Timing: Tesla secured a $465M government loan in 2010, before the political environment shifted against cleantech subsidies
- Monopoly: Tesla started with the tiny niche of high-end electric sports cars before expanding
- People: Elon Musk was an engineer and salesman, not a suit-wearing corporate executive
- Distribution: Tesla owned its entire distribution chain, selling directly to customers through its own stores
- Durability: Tesla’s lead in battery technology, brand, and manufacturing gave it a durable moat
- Secret: Tesla recognized that people wanted electric cars for performance and status, not just environmental virtue
Social Entrepreneurship and the Ambiguity Problem
Thiel also critiques the concept of “social entrepreneurship.” When companies define themselves by their opposition to something (fossil fuels) rather than by a specific positive vision, they tend to produce vague plans and mediocre results. The best companies solve a specific problem exceptionally well — they do not try to save the world in general terms.
The Clarity Test
- Successful companies have a specific, concrete plan — not a vague aspiration to “do good”
- Defining yourself by what you are against (fossil fuels, incumbents) is weaker than defining yourself by what you uniquely offer
- If a cleantech company could not explain its specific advantage without referencing environmental urgency, it probably did not have one
Key Takeaways
- Every business must answer seven fundamental questions about engineering, timing, monopoly, people, distribution, durability, and secrets
- Most cleantech companies failed because they got most or all of these questions wrong
- Tesla succeeded by answering all seven questions well — especially by starting with a small niche and having genuinely superior technology
- Vague social missions are not a substitute for specific, concrete business plans
- The 10x rule applies: incremental improvements are not enough to displace entrenched incumbents
- Do not follow trends — build on genuine contrarian insights
