Iberdrola, Enel, GE Vernova, Vestas, ReNew and Adani Green are among the companies creating significant renewable-energy employment through investment in power grids, solar and wind projects, manufacturing, battery storage, R&D and supply chains in 2026.
The renewable-energy employment market is becoming larger but also more complex. Global renewable energy supported approximately 16.6 million jobs in 2024, according to the latest International Renewable Energy Agency data, and employment could reach around 30 million by 2030.
Solar photovoltaic remains by far the biggest renewable employer, supporting around 7.2 million jobs, according to IRENA’s latest annual review.
However, identifying the world’s largest renewable-energy employers requires looking beyond company headcount.
A utility may directly hire thousands of workers while supporting hundreds of thousands of jobs among equipment manufacturers, contractors and suppliers. Wind and solar manufacturers create long-term industrial employment, while developers can temporarily employ large construction workforces when building multi-gigawatt projects.
The companies generating the greatest employment impact in 2026 are increasingly those combining renewable generation with grids, manufacturing, storage, supply chains and technology.
Iberdrola Plans 15,000 New Jobs and Supports 500,000 Across Value Chain
Iberdrola has one of the clearest quantified employment commitments among global energy companies.
Under its 2025-2028 Strategic Plan, the Spanish utility expects to create 15,000 new jobs worldwide while investing €58 billion through 2028.
The company also plans approximately €65 billion of purchases from thousands of suppliers, supporting more than 500,000 jobs across its value chain. Iberdrola will invest another €1.6 billion in R&D during the period.
The Iberdrola 2025-2028 Strategic Plan allocates €37 billion to electricity networks and €21 billion to generation and customers.
The distinction matters. Iberdrola’s €58 billion program should not be characterized entirely as renewable investment. Around two-thirds is going into networks, which are increasingly becoming one of the biggest employment engines of the energy transition.
Transmission and distribution expansion creates demand for electrical engineers, construction specialists, line workers, technicians, digital-grid experts, equipment manufacturers and project managers.
Iberdrola therefore illustrates a major change in renewable employment: jobs are following the infrastructure needed to connect clean generation, not just the wind and solar plants themselves.
Enel’s €53 Billion Investment Creates a Broad Clean-Energy Workforce
Enel is pursuing another massive investment program spanning renewables, grids and customers.
Enel’s 2026-2028 Strategic Plan calls for more than €53 billion of investment, including approximately €20 billion for renewable energy.
Enel expects the renewable investment to add roughly 15 GW of capacity, taking its portfolio from around 68 GW at the end of 2025 to more than 80 GW by 2028.
Approximately 9 GW of the additions will come through greenfield development and around 6 GW through brownfield investments. More than 75 percent of new renewable capacity is expected to involve wind and battery energy storage.
This scale creates employment across project development, permitting, engineering, procurement, construction, operations and maintenance.
Battery storage adds another category of skilled employment involving power electronics, battery engineering, software, safety, commissioning and energy-market optimization.
Enel is therefore an example of why the next clean-energy employment cycle will increasingly combine renewable power with storage and grid infrastructure rather than treating solar and wind as standalone industries.
GE Vernova: 85,000 Workers and New Advanced Energy R&D Jobs
GE Vernova represents the manufacturing and technology side of the energy transition.
The company has approximately 85,000 employees across more than 100 countries, with businesses covering wind power, electricity generation, grid equipment, electrification and energy technology.
Its employment footprint demonstrates why renewable-energy job rankings should include equipment manufacturers as well as project developers.
In July 2026, GE Vernova opened an expanded Advanced Research Center in Niskayuna, New York.
The facility forms part of a more than $110 million investment by GE Vernova and New York State and is expected to create 75 additional research positions. GE Vernova itself invested nearly $100 million in the new center.
The GE Vernova Advanced Research Center expansion illustrates how the energy transition is generating higher-value positions for engineers, researchers, materials specialists and other advanced-technology professionals.
Manufacturing adds jobs in production, quality control, automation, maintenance and supply-chain management.
This type of employment can also be more durable than temporary construction work associated with an individual solar or wind farm.
Vestas Shows the Employment Potential of Offshore Wind Manufacturing
Vestas, the leading wind-turbine manufacturer, has proposed investing more than €250 million in a new Scottish nacelle and hub manufacturing facility.
The factory could create up to 500 skilled direct jobs and manufacture nacelles and hubs for the company’s V236-15.0 MW offshore wind turbine. Production could begin in 2029 or 2030, subject to sufficient UK orders and planning approvals.
Vestas employs more than 29,000 people, has installed more than 201 GW of wind turbines across 86 countries, and services more than 129 GW of wind capacity.
ReNew Employs 4,586 Across Power and Solar Manufacturing
India’s ReNew offers one of the clearest examples of vertical integration creating multiple categories of renewable-energy employment.
ReNew reported a 4,586-person workforce in FY2025-26, including 2,015 manufacturing employees and 2,571 employees in its independent power business.
The company had 12.6 GW of commissioned renewable capacity, while its wider portfolio reached approximately 20 GW, including 1.7 GW / 6.2 GWh of battery energy storage.
Manufacturing is becoming particularly important.
ReNew’s platform includes 6.4 GW of solar-module manufacturing capacity and 2.5 GW of solar-cell capacity.
Another 4 GW of TOPCon solar-cell capacity and a 6.5 GW ingot-wafer manufacturing facility are under development. ReNew is investing approximately INR 42 billion in the Andhra Pradesh ingot-wafer facility.
That investment moves employment further upstream from simply assembling modules toward a broader domestic solar supply chain.
ReNew also reported 174,549 hours of learning and development and 634,824 hours of on-site health and safety training, illustrating the growing need for workforce development as renewable manufacturing becomes more technologically sophisticated.
Adani Green’s 5 GW Annual Addition Creates Project Employment
Adani Green Energy represents a different employment model: massive project deployment.
The company added 5,051 MW of renewable capacity during FY2025-26, including 3,409 MW of solar, 686 MW of wind and 956 MW of hybrid capacity.
Its operating renewable portfolio consequently reached approximately 19.3 GW.
Adding more than 5 GW in a single year creates substantial activity across engineering, procurement, civil construction, electrical installation, logistics and commissioning.
However, project capacity should not be converted directly into permanent job numbers.
Solar and wind construction can employ large contractor workforces for limited periods, while operating plants typically need significantly fewer permanent employees.
This distinction is essential when comparing a developer such as Adani Green with manufacturers such as Vestas or GE Vernova.
Manufacturing Is Becoming Critical to Renewable Job Creation
The biggest long-term employment opportunity may increasingly come from manufacturing rather than power-plant construction.
Solar manufacturing encompasses polysilicon, ingots, wafers, cells, modules, glass, frames, inverters and power electronics. Wind manufacturing covers blades, towers, nacelles, generators, bearings and numerous components.
Battery storage extends the opportunity into cathodes, anodes, cells, battery packs, thermal management, power electronics and recycling.
The geographic concentration of renewable jobs demonstrates why manufacturing matters.
China accounted for approximately 7.3 million renewable-energy jobs in 2024, or around 44 percent of the global total, according to the underlying industry data. Asian economies also dominate global solar PV employment.
Countries that import panels and turbines capture employment from project development, installation and maintenance.
Countries that manufacture the equipment can additionally create large industrial workforces serving hundreds or thousands of renewable projects.
Grids and Storage Become the Next Employment Engines
The investment plans of Iberdrola and Enel also demonstrate that the definition of a “renewable job” is broadening.
Iberdrola is investing €37 billion in electricity networks because new renewable generation cannot be integrated without additional transmission and distribution infrastructure.
Grid expansion creates demand for transformers, switchgear, substations, transmission cables, software, cybersecurity and control systems.
Battery storage is creating another specialized workforce.
Utility-scale BESS projects require electrical engineers, battery specialists, power-conversion experts, safety professionals and commissioning technicians. Operating the assets requires software for monitoring, predictive maintenance and electricity-market optimization.
The fastest-growing clean-energy employers may therefore increasingly sit at the intersection of renewables, electricity networks, batteries and digital technology.
AI Is Changing the Skills Renewable Employers Need
At the same time, renewable employment is becoming more technology-intensive.
Artificial intelligence is increasingly used for wind and solar forecasting, predictive maintenance, grid management, energy trading and battery optimization. Digital twins can monitor turbines and power plants, while automation and robotics are improving manufacturing productivity.
This creates jobs for software engineers, data scientists, cybersecurity specialists, AI professionals and robotics engineers alongside traditional electrical, mechanical and civil engineering roles.
But automation also explains why employment may not rise at the same speed as installed renewable capacity.
Factories and renewable projects are becoming more productive, meaning each gigawatt can increasingly be manufactured, installed and operated with fewer workers.
Which Renewable Companies Are Creating the Most Jobs?
There is no reliable single ranking because the employment figures measure different things.
Iberdrola stands out for its explicit commitment to 15,000 new hires and support for more than 500,000 value-chain jobs, backed by €58 billion of investment.
GE Vernova already employs around 85,000 people, giving it one of the largest direct workforces among energy-transition technology companies.
Vestas, with more than 29,000 employees, demonstrates the industrial employment potential of wind manufacturing and services.
ReNew provides a strong Indian example, employing 4,586 people while expanding solar cells, modules, wafers, storage and renewable generation.
Enel’s €53 billion-plus investment plan, including €20 billion for renewables, should drive employment across renewable projects, BESS and electricity infrastructure, while Adani Green’s 5,051 MW annual capacity addition demonstrates the scale of construction and project activity associated with rapid renewable deployment.
The IRENA renewable-energy employment outlook suggests the global renewable workforce could expand from 16.6 million today to around 30 million by 2030.
The companies capturing the greatest share of that employment growth will not necessarily be those building the most solar and wind capacity.
The strongest job creators are likely to be companies connecting renewable projects with manufacturing, grids, batteries, R&D, digital technology and domestic supply chains.
