Sustainability at EnerSys

Sustainability, reliability and resilience are at the core of who we are and what we do at EnerSys every day. Our products help tackle some of our world’s most significant challenges, be it addressing the impacts of climate change, decarbonization, efficient and affordable distribution of goods, grid reliability, telecommunications, and even medical safety. Our batteries and energy storage solutions are part of building a resilient, low-carbon future.

Sustainability at EnerSys is, however, about more than just the benefits and impacts of our products. Our commitment encompasses essential environmental, social and governance (ESG) issues fundamental to how we manage our own operations.

Minimizing our environmental footprint and providing a safe and inclusive workplace for our employees are top priorities for EnerSys. Being an excellent neighbor and good corporate citizen in the communities where we work and live is extremely important as well. Our products facilitate positive environmental, social and economic impacts around the world.

We are Climate Technology

Our technologies power a more sustainable future. Battery storage and energy systems allow for more effective and rapid decarbonization by connecting when power is made from intermittent renewable sources to when power is needed. This supports global greenhouse gas emissions reduction goals and helps to slow the impacts of climate change. Our technologies also support communities when they need it most by providing reliable and affordable access to energy. EnerSys products are climate technology, and we are energized by the impact they have worldwide.


The electrical grid – a keystone of everyday modern life and prosperity – is changing rapidly. Electrification of heating and transportation is replacing the direct burning of fossil fuels. The result will be a significant increase in demand for electricity. When produced by renewable sources, like wind and solar, there is a positive environmental impact. However, renewable energy is often intermittent, placing yet more stress on an already strained grid. At the same time, aging infrastructure and changing weather patterns resulting in more frequent and severe weather are threatening the reliability and resiliency of the grid across the United States and around the world.

Our products provide our customers and the communities they serve with the means to manage their power demands while also providing the security and stability of a consistent and available power supply.

EnerSys provides reliable power to cell towers, hospitals, data centers and even reinforces electrical grids. This means that we are vital to the infrastructure that delivers power anytime it is needed, especially when it is needed most. This was particularly apparent during the Texas power outages in February of 2021. Our energy storage products supplied backup power to cell towers, ensuring that vital communications services were uninterrupted throughout the emergency.

We are there when people need us most. During natural disasters, mobile nanogrid trailers equipped with Outback™ Inverters, photovoltaic panels and energy storage are used to provide emergency power for residents and first responders. Our battery storage products can also help make grids more efficient, reducing the stress and demand during peak generation.


Around the world, physicians and patients rely on EnerSys batteries for critical medical devices because they are safe and reliable sources of power. We provide long-lasting, reliable batteries for life-enhancing medical devices, like spinal cord stimulators and cochlear implants. These devices can, for example, allow a child to hear for the first time. Our batteries also power life-critical diagnostic equipment like mobile defibrillators and maneuverable x-ray machines.


For the world to reach net-zero carbon emissions by 2050 and address the worst impacts of the climate crisis, the zero-carbon electricity provided by renewable energy will need to be more accessible and reliable. Electricity can produce zero emissions if it is from a clean and renewable source like wind, hydro or solar power. However, the burning of fossil fuels can never be a zero-carbon energy source, making electrification the key to decarbonization. It is critical to have scalable and distributed energy storage solutions – after all, the sun does not always shine, and the wind does not always blow. At EnerSys, through both our current portfolio and our ongoing work developing solutions to these challenges, we are driven to provide solutions to advance and accelerate the viability of a low-carbon economy. Our products provide the storage solutions needed to maximize the reliability of energy generated from renewable sources, even during peak demand.

Our batteries and energy storage solutions also help our customers achieve their carbon reduction and renewable energy goals. In fact, more than 20 of our top customers have committed to RE100, a global corporate renewable energy initiative bringing together the world’s most influential businesses committed to 100% renewable energy. We are proud to support the ambitious goals of our customers and are evaluating opportunities for our business as well.


EnerSys helps keep the global economy moving by providing batteries, chargers and monitoring services to ensure the reliability and reduce the environmental impact of essential vehicles. This enables vital materials and goods to get where they need to be when they need to be there. Whether it is cold chain trucks transporting vaccines or forklifts moving edibles from apples to zucchini, our customers rely on EnerSys to power their mobility needs, repair and other services, and it doesn’t stop there. Trains, airplanes, boats and even submarines feature EnerSys batteries to ensure critical functions always have the power they need to keep passengers and crew safe. Our reputation for top quality and reliability also extends to governments looking to procure the energy backup and storage solutions they need.
