Funding a solar revolution

In the 1950s, commercial solar silicon photovoltaic (PV) cells came onto the market. For the first time, the sun powered satellites, radios, and even heating systems. Despite these early successes, the expensive and novel technology did not inspire an immediate energy revolution.

That changed dramatically with the energy crises of the 1970s. The U.S. had about 6% of the world’s population, but used 30% of the world’s energy, and that demand kept growing. As limited supply and greater demand led to price spikes, President Richard Nixon started price controls in 1971 to create artificially affordable gas. His domestic policies could not influence the international market, however.

America had ceased being an exporter of oil in the 1950s, and depended on imports for about one-third of its energy by the 1970s. In 1973, the U.S. allied in support of Israel during the Yom Kippur War. The Arab members of the Organization of the Petroleum Exporting Countries united to retaliate with an embargo on oil exports. The cost of a barrel of oil jumped immediately from $3 to $12. Gas stations closed as cars lined around the block to fill their tank. Families bought sweaters and dropped their home heating thermostats to a recommended 68 degrees. The first federal speed limits were posted on the nation’s highways to reduce unnecessary speed and gas usage.

The first embargo lasted only five months but resulted in years of additional disruptions, brownouts, gas shortages, and fear. The crisis deepened with another embargo following the 1979 Iranian Revolution.

At the same time, Americans debated the impact of energy production as the early environmental movement took shape. People searching for cleaner air and water organized and helped create the first federal regulation of pollution. Concerned citizens gathered to celebrate the first Earth Day on April 22, 1970.

Growing environmental activism ensured that the U.S. would invest in green energy solutions as it looked for solutions to the energy crisis. Government grants funded research projects, and the state and federal tax deductions encouraged a revolution of energy efficiency. Private investment from banks like Wells Fargo offered additional momentum.

Investing in early technologies

In 1976, developers in California’s Silicon Valley wanted to be part of the green energy movement. After learning that about 30% of domestic energy use came from space heating, the developers sought a better solution with a solar-powered heating and cooling system for a new project.

Many homes today use solar panels as an alternative to the electrical grid. But technical limitations at the time turned heating and cooling into the most popular use of solar power. These thermal solar systems used the heat of the sun to warm water circulated through panels in copper tubes. Sophisticated air control systems manipulated the resulting air currents to make a building warmer or colder.

While some industrial plants had retrofitted buildings with solar-powered heating, the Silicon Valley developers planned to utilize solar from the start, making it possibly the first solar system planned for a new commercial building. At more than 100,000 square feet, it was also believed to be the largest industrial use of solar in the U.S. at the time. While many banks considered solar a risky investment, Wells Fargo provided $2 million in construction loans to the project — more than $11 million adjusted for inflation in 2023. The building opened in 1978 to national attention as representative of a new era in American architecture.

Since then, the solar industry has continued to evolve. Technology has become more efficient and more affordable, even resulting in energy surpluses. Wells Fargo has continued to invest in renewable energy projects.

Solar at Wells Fargo

Just as families and communities faced difficulties during the energy crisis, Wells Fargo and other banks saw their operations costs skyrocket. Companywide conservation drives turned off signs and lowered heat. From 1973 to 1974, Wells Fargo reduced its energy use by 24%.

Meanwhile, the Corporate Responsibility Committee at Wells Fargo set goals for greener alternatives. In 1979, Wells Fargo installed a solar heating and cooling system as a test at a branch in Culver City in sunny Southern California. As the property manager said at the time, “You can talk theory forever, but until you actually try it, you don’t really know how effective it will be.”

The branch used an array of 840 square feet of solar panels to heat water in copper tubes. Glass walls ensured that customers could see the $48,000 solar thermal system at work. As solar technology continued to evolve, Wells Fargo continued experimenting with solar systems and renewable energy.

The Environmental Protection Agency recognized Wells Fargo as the nation’s largest purchaser of Renewable Energy Certificates in 2006, the same year the company launched a business focused solely on providing financing to renewable energy projects. The company made a sector-leading renewable energy commitment in 2016, and began meeting 100% of its global electricity requirements with renewable energy the following year.

Today, Wells Fargo maintains solar arrays on 16 properties, in addition to a number of solar-powered ATMs, and has announced plans to bring on-site solar generation to close to 100 new branch and corporate buildings.

Wells Fargo solar timeline

2005-2006

Wells Fargo announces 10-point Environmental Commitment that includes the company’s first sustainable finance goal: $1 billion in lending over five years to green companies.

2014

Wells Fargo and the U.S. Department of Energy’s National Renewable Energy Laboratory launch the Innovation Incubator (IN2) program. This environmental grant program is designed to accelerate the development and commercialization of early-stage clean technologies and foster a clean technology ecosystem.

2015

Projects owned in whole or in part by Wells Fargo produce more than 10% of all solar photovoltaic and wind energy generated in the U.S.

2017

Wells Fargo begins meeting 100% of global electricity requirements with renewable energy, primarily through the purchase of Renewable Energy Certificates, or RECs, in line with the first phase of its 2020 renewable energy goal.

2018

Wells Fargo makes a $200 billion sustainable finance commitment through 2030, with at least 50% going toward renewable energy and clean technology projects. Wells Fargo also provides $5 million in seed funding to create the Tribal Solar Accelerator Fund with the nonprofit GRID Alternatives to support solar projects in tribal communities.

2019

Wells Fargo announces a renewable energy transaction that will power 400 Wells Fargo properties in Texas from a new utility-scale solar installation in the state. It is the first major transaction under the second phase of the company’s renewable energy goal — to transition from purchasing RECs to entering into long-term contracts that support the development of net-new renewable assets located near its load centers. The company also announces it will expand its portfolio of on-site solar arrays to more than 100 corporate properties.

The Wells Fargo Innovation Incubator is selected as a Bloomberg New Economy Forum Solution and received the U.S. Chamber of Commerce Foundation 2019 Citizens Award for Environmental Stewardship.

Wells Fargo achieves carbon neutrality for Scope 1 and Scope 2 emissions.

2020

Wells Fargo Corporate Properties Groups (CPG) executes long-term agreements for renewable energy locations in eight additional states, the District of Columbia and the Philippines. At years end, CPG had entered into a total of nearly 120 long-term contracts that support the development of over 750 megawatts of net-new renewable energy assets.

The Renewable Energy and Environmental Finance group reaches $10 billion in financing for utility-scale renewable energy projects, accounting for 12% of all wind and solar energy capacity in the U.S. over the past 10 years.

2021
