Energy efficiency

Our products are energy efficient, help conserve resources, and save costs. In short, they are good for our customers and the environment.

As fossil fuels become ever scarcer, global energy demand continues to increase. Against this backdrop, the European Parliament adopted the EU Energy Efficiency Directive in September 2012, which aims to increase energy efficiency in the European Union by 20 percent by 2020. With sustainable solutions Bosch helps its customers to systematically decrease their energy consumption.


Bosch has taken a systematic approach to conserving resources in its production activities.

About 32 percent of global energy consumption is the result of industrial activity, and there is considerable potential for improvement. If manufacturing facilities were to use the best technology available, energy consumption could be reduced by about a quarter between now and 2030. Bosch aims to play a pioneering role in this regard. By 2020, the company aims to reduce the CO₂ emissions of its own locations by 20 percent over 2007 levels. It has made considerable progress already: at plants that have already completed the implementation phase, emissions have been reduced by as much as 30 percent.

In order to save energy without negatively affecting productivity, the company has developed the comprehensive “Rexroth for Energy Efficiency (4EE)” approach. The number stands for the four dimensions that the company has included in its systematic analysis:

1. Does the facility’s size reflect its production targets?
2. Can its individual components be made more energy efficient?
3. In which areas are there energy surpluses that could be used elsewhere?
4. Are resources being used appropriately?

At the Reutlingen manufacturing location, for instance, Bosch now saves some 10,000 tons of CO₂ as a result of the program. In addition, the plant covers 90 percent of its heating needs with waste heat.

Bosch also draws on its energy conversion expertise in its role as industrial and research partner for the “ETA”factory pilot project, which is being conducted under the leadership of Darmstadt Technical University. The project aims to further reduce energy consumption in industrial production, and the project stakeholders expect energy savings potential of up to 40 percent.

Household appliances

The BSH Hausgeräte GmbH super efficiency portfolio helps to save energy.

BSH Hausgeräte GmbH’s super efficiency portfolio comprises the company’s most energy-energy efficient products, which are based on the European energy label. All of the products in this particular portfolio consume so little energy or water that they are in the best energy efficiency class for their category. Products include washing machines and dishwashers as well as refrigerators with A+++ or A++ efficiency ratings, and stoves, ovens, and dryers with an A label.

With its super efficiency portfolio, BSH GmbH contributes to reducing the energy consumption of households. To make these savings measurable, the company has compared the annual energy consumption of its super efficient products with the average consumption of all products sold in the same year.

Consumers also benefit from updated products: a household with super-efficient appliances can reduce its annual energy costs by 300 euros.


Thanks to Bosch technology, low-consumption heaters can be turned into intelligent energy savers.

Buildings account for 40 percent of the world’s energy consumption. With the help of efficient technology and individual energy services, considerable amounts of power, heat, and carbon dioxide can be saved.

For residential buildings, heat generation accounts for the lion’s share of energy consumption. At present, around 75 percent of all installed heating systems in Germany are technically outdated and consume unnecessarily high amounts of energy. Switching to a condensation boiler, especially if is combined with solar arrays, pays off very quickly with high energy savings. If modern Bosch heating technology were used across the board in Germany, some 50 million tons of CO₂ could be saved — this is equal to about a third of CO₂ emissions resulting from road traffic in Germany.

The intelligent networking of energy production and consumption with the help of MEMs sensors is giving rise to additional savings potential. These sensors can measure the temperature and humidity of a room and send the data to the homeowner via the internet or a smart phone app. Homeowners can then regulate their heating systems based on these data updates. In the future, a growing number of objects and devices will become automated helpers for energy savings.

In commercial buildings, the smart networking of energy systems already has significant energy-saving. Among other things, Bosch offers its industrial customers highly efficient equipment for cogeneration, as well as OCR systems that turn waste heat into electricity.
