Top Industries That Use the Most Electricity (2026 Data)

1. Manufacturing Electricity Consumption

Manufacturing is the single largest consumer of electricity in the United States, using approximately 955 billion kWh per year, which accounts for 24.3% of total national electricity consumption. This dominance stems from the sector's reliance on energy-intensive processes: electric arc furnaces, motor-driven equipment, compressed air systems, and industrial heating.

According to the EIA's Manufacturing Energy Consumption Survey (MECS), the most electricity-intensive manufacturing subsectors include primary metals (steel, aluminum), chemicals, petroleum refining, paper products, and food manufacturing. A single large steel mill can consume as much electricity as a city of 100,000 residents.

Key Energy Cost Drivers in Manufacturing

• Motor-driven systems: Account for roughly 70% of manufacturing electricity use (DOE Advanced Manufacturing Office).
• Process heating and cooling: Furnaces, kilns, and industrial chillers require sustained high-wattage power.
• Compressed air systems: Consume 20% to 30% of plant electricity in many facilities, often with significant waste.
• 24/7 operations: Most manufacturing plants run multiple shifts, eliminating opportunities for off-peak savings without deliberate load shifting.
• Peak demand charges: Large facilities face demand charges that can represent 40% to 60% of the total bill.

Manufacturing facilities spend between $350,000 and $800,000 per month on electricity, with the highest costs concentrated in primary metals, chemicals, and paper production. For manufacturers in deregulated markets, comparing commercial electricity rates across multiple providers is one of the most direct paths to reducing this expense.

2. Data Center Electricity Consumption

Data centers are the second-largest and fastest-growing electricity consumers in the U.S., using approximately 206 billion kWh annually, or 5.2% of total national usage. The International Energy Agency (IEA) projects global data center electricity demand will more than double by 2030, with U.S. facilities driving a significant share of that growth.

The DOE's 2024 report on data center energy consumption found that AI training workloads and generative AI inference are accelerating demand far beyond previous projections. A single hyperscale data center can consume 100 MW or more of continuous power, equivalent to roughly 80,000 homes.

Key Energy Cost Drivers in Data Centers

• Server and compute loads: IT equipment accounts for approximately 40% to 50% of total facility electricity use.
• Cooling systems: Data centers must maintain precise temperature ranges (64°F to 80°F), with cooling representing 30% to 40% of total consumption.
• Power Usage Effectiveness (PUE): Average PUE across the industry is 1.58, meaning 58% additional energy is consumed for non-computing functions (Uptime Institute, 2024).
• Redundancy requirements: Uninterruptible power supplies (UPS) and backup generators add to the overall energy footprint.
• AI workload expansion: Training a single large language model can consume as much electricity as 100 U.S. homes use in a year (DOE, 2024).

Monthly electricity costs for a mid-size data center range from $500,000 to $2,000,000. Hyperscale facilities operated by major cloud providers can exceed $5 million per month. Given these figures, securing favorable large commercial energy rates is a board-level priority for data center operators. 

3. Commercial Real Estate (Office Buildings) Electricity Consumption

Commercial office buildings collectively consume approximately 143 billion kWh of electricity per year, representing 3.6% of total U.S. usage. This makes commercial real estate the third-largest electricity-consuming industry. The primary demand comes from HVAC systems, lighting, elevators, and tenant plug loads (computers, monitors, printers).

According to EIA CBECS data, the average U.S. commercial office building uses 17.3 kWh per square foot annually. Class A office towers in major metropolitan areas typically use 20 to 25 kWh per square foot due to higher density, more complex mechanical systems, and extended operating hours.

Key Energy Cost Drivers in Commercial Real Estate

• HVAC systems: Represent 35% to 45% of total building electricity consumption (EIA CBECS).
• Lighting: Accounts for 15% to 25%, though LED retrofits have reduced this share significantly.
• Plug loads: Tenant electronics and appliances consume 20% to 30% of total electricity and are the hardest to control.
• Elevators and escalators: High-rise buildings see 5% to 10% of usage from vertical transport.
• Building age and envelope quality: Older buildings without modern insulation or window glazing require substantially more cooling and heating energy.

Average monthly electricity costs for commercial office buildings range from $15,000 for a mid-size suburban property to $85,000 or more for a Class A high-rise. Property managers and building owners in deregulated energy markets can significantly reduce operating expenses by benchmarking electricity rates across multiple suppliers.

Monthly electricity costs for religious institutions range from $1,500 for a small community church to $6,000 or more for a large campus or megachurch. Many congregations operate on tight budgets, so energy cost savings go directly toward mission and programming. 

How These Industries Can Reduce Electricity Costs

Electricity is a controllable operating expense. Across all 10 of the industries listed above, organizations that actively manage their energy costs outperform those that simply pay whatever rate their utility assigns. Here are the most effective strategies, ranked by typical impact on the bottom line.

Energy Procurement and Rate Optimization

In deregulated electricity markets like Texas, businesses can choose their electricity supplier. This single factor creates the largest cost-saving opportunity for most commercial and industrial users. Organizations that compare rates from multiple retail electricity providers, or use a broker to solicit competitive bids, typically secure rates 12% to 22% below default tariffs, according to DOE procurement studies.

Key procurement tactics include:

• Competitive bidding: Soliciting quotes from 5 to 10 providers simultaneously to drive competition.
• Reverse auctions: Letting suppliers compete in real-time to offer the lowest rate.
• Contract timing: Locking in rates during periods of low wholesale prices (typically spring and fall in Texas).
• Blended contract structures: Combining fixed-rate and index-rate components to balance price certainty with market upside.

Businesses spending $8,000 or more per month on electricity stand to save the most from strategic procurement. Getting started with a rate comparison takes minutes and requires no commitment.

Load Management and Demand Response

Peak demand charges, calculated based on the highest 15-minute interval of electricity use during a billing period, can account for 30% to 70% of an industrial customer's bill. Reducing peak demand through load shifting, staggered equipment startups, and automated demand response systems can produce immediate savings.

For manufacturing plants and data centers, even a 5% to 10% reduction in peak demand can save $10,000 to $100,000 per month.

Contract Optimization and Renewal Strategy

Many businesses lose money by auto-renewing electricity contracts or signing renewals without comparing market rates. Best practices include beginning the renewal process 6 to 12 months before contract expiration, benchmarking your current rate against the broader market, and negotiating terms beyond just price (early termination clauses, bandwidth provisions, and renewal options). 

Energy Efficiency and Sustainability

While efficiency improvements typically require capital investment, they deliver compounding returns. The most impactful measures vary by industry:

• LED lighting retrofits: 40% to 60% reduction in lighting electricity, with payback periods of 1 to 3 years.
• HVAC upgrades and controls: Variable frequency drives (VFDs) on motors and smart building management systems (BMS) can cut HVAC consumption by 20% to 35%.
• Renewable energy contracts: Solar and wind PPAs offer long-term price stability, often at or below current retail rates.
• On-site solar and battery storage: Particularly effective for warehouses, retail, and religious institutions with available roof space.

Many utilities and state programs offer rebates and incentives for efficiency upgrades. The DOE's Better Buildings Initiative reports that participating organizations have saved over $14 billion in cumulative energy costs since 2011.

Frequently Asked Questions

What industry uses the most electricity?

Manufacturing uses the most electricity of any industry in the United States, consuming approximately 955 billion kWh per year. This accounts for about 24.3% of all U.S. electricity usage. Primary metals (steel and aluminum production), chemical manufacturing, and petroleum refining are the most electricity-intensive subsectors within manufacturing.

How is electricity consumption measured by industry?

Electricity consumption by industry is measured in kilowatt-hours (kWh) and tracked by the U.S. Energy Information Administration (EIA) through two primary surveys: the Manufacturing Energy Consumption Survey (MECS) for industrial users and the Commercial Buildings Energy Consumption Survey (CBECS) for commercial buildings. These surveys collect data on total annual consumption, energy intensity per square foot, and end-use breakdowns.

Why do manufacturing plants use so much electricity?

Manufacturing plants use enormous amounts of electricity because of motor-driven systems (which account for 70% of plant electricity), process heating and cooling, compressed air systems, and 24/7 operations. A single electric arc furnace in a steel mill can draw 50 to 100 MW of power during operation, equivalent to a small city's demand.

Are data centers the fastest-growing energy consumers?

Yes. Data centers are currently the fastest-growing category of electricity consumers in the United States. The DOE projects data center electricity demand will increase by approximately 10% per year through 2030, driven primarily by artificial intelligence workloads, cloud computing growth, and the expansion of streaming and digital services. Total U.S. data center consumption is projected to exceed 300 billion kWh by 2028.

How much can businesses save by switching electricity providers?

Businesses in deregulated electricity markets typically save 12% to 22% on annual electricity costs by comparing business electricity rates and switching to a more competitive provider, according to DOE estimates. For a facility spending $50,000 per month on electricity, that translates to $72,000 to $132,000 in annual savings. The savings potential increases for larger consumers who can attract more competitive bids from suppliers.

What percentage of U.S. electricity does the commercial sector use?

The commercial sector accounts for approximately 35% of total U.S. electricity consumption, according to the EIA Annual Energy Outlook 2025. This includes office buildings, retail stores, hospitals, hotels, restaurants, warehouses, and other non-industrial commercial buildings. The industrial sector, dominated by manufacturing, accounts for an additional 26%.

How do peak demand charges affect industrial electricity bills?

Peak demand charges are based on the highest 15-minute interval of electricity usage during a billing cycle and can represent 30% to 70% of a large industrial customer's total bill. These charges penalize facilities that have large, sudden spikes in power draw, even if their average consumption is moderate. Managing peak demand through load shifting, staggered startups, and automated controls is one of the most effective cost-reduction strategies for industrial users.

What is the average electricity cost per square foot for commercial buildings?

The average electricity cost for U.S. commercial buildings is $2.10 to $2.50 per square foot per year, based on EIA CBECS data. However, this figure varies significantly by building type. Restaurants average $4.50 to $6.00 per square foot. Hospitals range from $3.50 to $5.00. Standard offices typically fall between $1.80 and $2.80. Warehouses are the lowest at $0.70 to $1.20 per square foot.

Do religious institutions qualify for commercial electricity rates?

Yes. In most deregulated electricity markets, including Texas, religious institutions (churches, synagogues, mosques, and temples) qualify for commercial electricity rates rather than residential rates. Many congregations are unaware of this option and overpay as a result. Religious organizations with monthly electricity bills of $1,500 or more should compare commercial electricity plans to determine if a better rate is available.
