Introduction
“Bitcoin wastes energy” is perhaps the most common criticism of cryptocurrency. But Major Jason Lowery’s Softwar thesis reveals a radically different perspective: Bitcoin doesn’t waste energy—it converts energy into security.
This reframing transforms the entire energy debate. Just as we don’t say militaries “waste” energy defending nations, Bitcoin’s energy consumption serves a strategic purpose: projecting physical power into digital space to secure property rights.
This article explores the strategic connection between Bitcoin mining and energy infrastructure, examining consumption patterns, mining economics, grid integration, and why energy expenditure is the foundation of Bitcoin’s unprecedented security model.
Understanding Bitcoin’s Energy Consumption
The Numbers: Context and Scale
Bitcoin’s Annual Energy Consumption (2025 estimates):
- Total: ~150-170 TWh (terawatt-hours) per year
- Continuous: ~17-19 gigawatts average power draw
- Percentage of global electricity: ~0.6-0.7%
Comparative Context:
| System | Annual Energy (TWh) | Purpose |
|---|---|---|
| Bitcoin | 150-170 | Secures $1+ trillion in digital assets |
| Gold mining | 240 | Extracts ~3,000 tons of gold annually |
| Banking system | 260 | Processes fiat transactions globally |
| Data centers | 200-250 | Hosts internet services |
| U.S. military | 200 | Provides national defense |
| Christmas lights (U.S.) | 6.6 | Seasonal decoration |
| Always-on devices (U.S.) | 60 | Idle power consumption |
| Clothes dryers (U.S.) | 60 | Household laundry |
Key Insight: Bitcoin uses less energy than gold mining, banking, or data centers—systems it partially replaces. Energy consumption should be evaluated against value provided, not absolute numbers.
Why Bitcoin Mining Requires Energy
The Thermodynamic Security Model
Traditional digital security:
- Relies on information secrecy (passwords, keys)
- Breached once information discovered
- Zero marginal cost to attack attempts
Bitcoin’s proof-of-work security:
- Relies on energy expenditure
- All information public (blockchain, code)
- Massive marginal cost for each attack attempt
- Energy consumption = security production
From Lowery’s framework: Energy isn’t wasted—it’s converted into thermodynamic security, creating the first cyber-physical defense mechanism.
The Security-Energy Relationship
More energy = stronger security:
- Higher hash rate requires more energy to attack
- Each joule spent by miners adds to network defense
- Cumulative energy creates immutability
- Security measurable in watts and hashes
Quantified: To attack Bitcoin requires:
- Matching 400+ EH/s of hash rate
- ~17-19 GW of continuous power
- $700,000+ per hour in electricity
- Energy expenditure makes attack economically impossible
Energy Consumption Trajectory
Historical Growth:
- 2009: Negligible (CPU mining)
- 2013: ~5 TWh/year
- 2017: ~30 TWh/year
- 2021: ~140 TWh/year (peak)
- 2025: ~150-170 TWh/year
Future Projections:
- Efficiency improvements: New ASICs use less energy per hash
- Price sensitivity: Higher Bitcoin price → more mining → more energy
- Halving impact: Block reward cuts reduce mining profitability
- Long-term trend: Gradual increase, but efficiency gains offset growth
Realistic 2030 Estimate: 180-250 TWh/year (factoring efficiency + adoption growth)
The Mining Economics-Energy Nexus
Mining Profitability Equation
Revenue:
- Block reward: 6.25 BTC per block (halves every 4 years)
- Transaction fees: 0.5-2 BTC per block
- Bitcoin price: Variable (affects fiat value)
Costs:
- Electricity: ~60-80% of total operational cost
- Hardware: Depreciation + upfront capital
- Facilities: Cooling, maintenance, labor
- Other: Internet, security, overhead
Profitability Formula:
Profit = (Block Reward + Fees) × BTC Price - (Electricity Cost + Hardware + Operations)Critical Variable: Electricity Cost
Since electricity is 60-80% of costs, miners are incentivized to seek cheapest power sources.
Global Hash Rate Distribution by Energy Cost
Cheapest Regions (Mining concentrates here):
-
Texas, USA: ~$0.03-0.06 per kWh
- Abundant wind and natural gas
- Grid stabilization incentives
- Favorable regulatory environment
- ~15% of global hash rate
-
Iceland: ~$0.03-0.05 per kWh
- 100% renewable (geothermal + hydro)
- Cold climate (natural cooling)
- ~2% of global hash rate
-
Paraguay: ~$0.02-0.04 per kWh
- Massive hydro capacity (Itaipu Dam)
- Energy surplus exports
- ~1-2% of global hash rate
-
Kazakhstan: ~$0.04-0.06 per kWh

- Energy surplus
- ~13% of global hash rate
-
Russia: ~$0.03-0.05 per kWh
- Natural gas abundance
- Siberian cooling advantages
- ~4-5% of global hash rate
Energy Arbitrage Result: Bitcoin mining gravitates toward stranded, surplus, or cheapest energy sources globally.
The “Buyer of Last Resort” Phenomenon
Bitcoin miners function as flexible energy buyers with unique characteristics:
Characteristics:
- Location flexible: Can set up anywhere with power + internet
- Interruptible load: Can shut down immediately when grid needs power
- Time flexible: Operate during low-demand periods
- Price sensitive: Only profitable with cheap electricity
Economic Impact:
- Monetizes stranded energy (otherwise wasted)
- Provides base load demand for new projects
- Generates revenue during low-demand periods
- Stabilizes grid economics
Example: Texas Wind Farm
- Wind generates power at night (low demand)
- Bitcoin miners purchase excess capacity
- Grid avoids curtailing renewable production
- Wind farm increases profitability
- Result: Bitcoin mining subsidizes renewable development
Strategic Energy-Bitcoin Connections
Connection 1: Energy Independence Through Bitcoin
National Energy Strategy:
Nations with energy surplus can leverage Bitcoin mining:
Russia Example:
- Natural gas abundance
- Limited export infrastructure to some regions
- Stranded gas (no pipeline access)
- Solution: Bitcoin mining monetizes stranded gas
- Result: Energy converted to digital asset, no physical export needed
Bhutan Example:
- Massive hydro capacity (glacial runoff)
- Small domestic population (low demand)
- Limited export options (landlocked)
- Solution: Government operates Bitcoin mining
- Result: 100% renewable mining, national revenue source
Strategic Implication: Energy-rich nations can export energy virtually through Bitcoin without physical infrastructure.
Connection 2: Grid Stabilization
The Grid Balancing Problem:
- Electricity must be consumed instantly (limited storage)
- Demand fluctuates throughout day
- Renewable generation is intermittent
- Grid operators pay to balance supply/demand
Bitcoin Mining Solution:
Demand Response:
- Miners shut down during peak demand (free up capacity)
- Grid pays miners to curtail (ancillary services market)
- Miners resume during off-peak (cheap electricity)
Real-World Example: ERCOT (Texas):
- Bitcoin miners registered as controllable load
- During February 2021 freeze: miners shut down, freeing 1+ GW
- During summer peaks: miners provide demand response
- Result: Improved grid reliability + miner profitability
Economic Win-Win:
- Grid: Flexible load management
- Miners: Revenue from curtailment payments + cheap off-peak power
- Consumers: Lower prices through grid efficiency
Connection 3: Renewable Energy Development
The Renewable Economics Problem:
- Solar/wind have high upfront costs
- Intermittent generation (sun/wind varies)
- Revenue only when selling power
- Challenge: Financing projects with unpredictable revenue
Bitcoin Mining as Development Catalyst:
Guaranteed Buyer:
- Mining provides base load demand
- Operates 24/7 (when profitable)
- Improves project economics
- Facilitates financing
Oilfield Flare Gas Example:
- Natural gas flared (burned as waste) in oil production
- ~140 billion cubic meters annually worldwide
- Environmental harm + wasted energy
- Bitcoin solution: Capture flare gas → generate electricity → mine Bitcoin
- Result: Waste converted to digital asset, emissions reduced
Renewable Project Financing:
- Developer proposes solar/wind farm
- Bitcoin mining provides guaranteed demand during development
- Project secures financing (predictable revenue)
- Facility builds out
- Over time, grid demand increases
- Mining gradually replaced by higher-value grid sales
- Result: Bitcoin mining subsidized renewable development during critical early phase
Connection 4: Energy as National Security
Lowery’s Framework: Energy access = Bitcoin mining capability = Hash rate control = Cyber-physical power projection
Strategic Energy-Security Linkage:
Energy Surplus Nations:
- Can dedicate capacity to Bitcoin mining
- Build hash rate (network influence)
- Generate Bitcoin revenue
- Develop cyber-physical security expertise
Energy Import-Dependent Nations:
- Cannot compete in mining economically
- Lack hash rate control
- Miss strategic positioning opportunity
- Depend on others for Bitcoin infrastructure
Geopolitical Implication: Energy independence enables Bitcoin sovereignty, creating new strategic energy incentives beyond traditional economic/security considerations.
Environmental Considerations
The Carbon Question
Criticism: Bitcoin mining increases carbon emissions.
Nuanced Reality:
Energy Mix Analysis (2024 estimates):
Bitcoin Mining Energy Sources:
- Renewable: ~52-56%
- Hydro: ~30%
- Wind: ~12%
- Solar: ~6%
- Geothermal: ~2%
- Natural Gas: ~30%
- Coal: ~15%
- Nuclear: ~3%
Comparison to Grid Average:
- Global electricity: ~37% renewable
- U.S. electricity: ~21% renewable
- Bitcoin: ~52-56% renewable
Conclusion: Bitcoin mining uses higher percentage of renewables than most electricity grids.
Why Bitcoin Favors Renewables
Economic Drivers:
- Cheapest sources first: Renewables often cheapest (hydro, wind, solar)
- Stranded energy monetization: Hydro in remote areas, excess solar/wind
- Waste energy capture: Flare gas, geothermal surplus
- Location flexibility: Can locate near renewable sources regardless of population centers
Result: Market forces push Bitcoin toward renewable energy adoption.
Methane Reduction Through Flare Gas Capture
Environmental Benefit: Capturing flare gas for Bitcoin mining reduces methane emissions (methane is 25x more potent greenhouse gas than CO2).
Mechanism:
- Oil wells produce natural gas as byproduct
- Without capture infrastructure, gas flared (burned) or vented (released)
- Bitcoin mining provides economic incentive to capture
- Gas generates electricity for mining
- Methane converted to CO2 (less harmful)
- Result: 25-50% reduction in greenhouse gas impact
Scale: If 10% of global flare gas used for Bitcoin mining:
- ~14 billion cubic meters captured
- ~37 million tons CO2-equivalent reduction
- Equivalent to removing ~8 million cars
Long-Term Trajectory: Decarbonization
Trend: Bitcoin mining increasingly renewable
Drivers:
- Cost: Renewables becoming cheapest energy source
- Availability: Stranded renewable capacity abundant
- Innovation: Battery storage improving economics
- Regulation: Carbon pricing incentivizes low-carbon mining
- Corporate: ESG pressure on mining companies
Projection: By 2030, Bitcoin mining could be 70-80% renewable—higher than most industries.

Conclusion: Energy as the Foundation of Digital Security
Bitcoin’s energy consumption isn’t a bug—it’s the feature that enables thermodynamic security. By requiring physical energy expenditure to add blocks, Bitcoin creates something unprecedented: digital property rights anchored to physical reality.
From Major Lowery’s strategic framework, this energy-security linkage has profound implications:
- Energy independence → Mining capability → Hash rate control → Cyber-physical sovereignty
- Nations with energy advantages gain strategic positioning in digital property infrastructure
- Energy policy directly impacts national security in the Bitcoin era
The question isn’t whether Bitcoin should use energy. The question is: Is securing $1+ trillion in digital assets worth 0.6% of global electricity?
Given that Bitcoin uses less energy than gold mining, banking, and data centers—while providing superior security and accessibility—the strategic answer is clear: Energy expenditure for thermodynamic security is strategically justified.
Understanding the energy-Bitcoin connection is essential for evaluating cryptocurrency’s role in future energy policy, environmental strategy, and national security planning.
