Industry plays a key role in the global energy transition, aiming to increase the share of renewable energy sources (RES) in the energy mix. The implementation of RES technologies in the industrial sector not only promotes sustainability, but also brings significant operational savings and improves energy efficiency. The use of RES allows companies to lower energy costs and reduce CO2 emissions, which is crucial in the context of changing environmental regulations.
RES technologies used in industry
- Energy storage
Energy storage is key to stabilising the operation of industrial energy systems. In manufacturing plants, where energy demand can fluctuate dynamically, energy storage facilities (such as lithium-ion batteries or flywheel technologies) allow surplus energy generated by photovoltaic or wind power installations to be stored. At times of peak energy demand, the stored energy can be used to power machinery, reducing the cost of purchasing energy from the grid and increasing energy independence. - Photovoltaics in industry
More and more companies are opting for photovoltaic installations on the roofs of their production facilities or building ground-based solar farms. Photovoltaics offer the possibility to produce energy for their own needs, which reduces energy costs and at the same time reduces CO2 emissions. By combining photovoltaic systems with energy storage, solar energy can also be used at night or during periods of less sunshine. - On-site wind farms
Wind turbine installations in regions with suitable wind conditions can provide a significant source of energy for industry. Decentralised wind farms can supply energy directly to production processes, reducing dependence on external energy suppliers and helping to reduce the carbon footprint.
Transition towards energy self-sufficiency
- Decentralisation of energy production
The development of renewable energy sources contributes to the decentralisation of energy systems. Instead of relying solely on energy suppliers, companies can produce energy for their own needs, which increases their resilience to supply disruptions. An example of this is industrial plants implementing RES-integrated microgrids, which enable autonomous operation in the event of an external grid failure. - Integrated energy management systems (EMS)
Modern energy management systems combine different energy sources (RES, conventional sources and energy storage) to optimise consumption and minimise costs. For example, at times of peak demand, an EMS system can automatically switch power to energy from storage, relieving the load on the external electricity grid.
Impact of regulation and government support on the development of RES in industry
- Financial incentives
Grant programmes and tax incentives for investments in renewable energy sources accelerate the implementation of new technologies. With financial support, companies can upgrade their installations faster and invest in RES technologies, which contributes to lower operating costs. - Regulation of CO2 emissions
Tightening greenhouse gas emission standards are forcing companies to look for low-carbon solutions, which encourages the adaptation of renewable energy sources. Through RES investments, companies can not only meet stringent regulatory requirements, but also build their image as sustainability leaders.
Why are RESs key for industry?
The development of renewable energy sources in industry enables companies to reduce operating costs, reduce emissions and increase energy independence. Investing in photovoltaics, wind farms and energy storage brings economic and environmental benefits, supporting sustainable development strategies. In the long term, RES technologies are becoming indispensable for industries seeking to meet the challenges of today’s market and changing environmental regulations.
By using modern solutions such as integrated energy management systems, companies can maximise the benefits of RES, increasing their energy efficiency and minimising their environmental impact.
