Energy Efficiency

Reducing energy consumption is more than a matter of image. From energy recovery to autonomous power stations, modern technologies are achieving efficiency ratings, that also have a remarkable effect on the bottom line.

It takes cooperation to save energy

Companies around the world are facing the need to manage their energy resources more efficiently. Synergies can help drastically cut energy costs, realize potential cost savings and achieve climate protection goals – wins across the board.

Efficiency is the ratio of cost to result. This common economic principle certainly applies to energy savings: If you can achieve the same or even a better result at lower cost, your efficiency increases.

One way for companies to implement this notion in practice is learning energy efficiency networks, or LEEN for short.

The core idea: ten or fifteen companies from the same sector or the same region meet regularly to share knowledge around energy savings, and take advantage of synergies. Instead of each one having to research for itself how to use their energy more efficiently, their shared knowledge grows exponentially for all.

Saving energy together is easier

This allows all of them to benefit from lower energy costs, save electricity and reveal previously unsuspected potential savings in energy consumption. Such change is urgent, with Germany still in sixth place in the list of the world's biggest greenhouse gas producers, behind China (25 percent share), the United States (17 percent), India (6 percent), Russia (5 percent) and Japan (4 percent). And 40 percent of carbon dioxide emissions come from the energy sector. Energy production here in Germany still relies on fossil fuels such as lignite and coal for almost two-thirds of the total.

This means that for every kilowatt-hour of power generated, more than 600 grams of carbon dioxide on average are released into the atmosphere, more than in many other countries.

Take advantage of massive energy savings potential

Experts are therefore calling for greater energy savings, particularly in business: Some 70 percent of power is consumed by industry, trade and service companies. Germany wants to reduce its total emissions by 40 percent by 2020 – and is supporting private households and businesses with subsidies for this purpose. The biggest energy consumers, the United States and China, recently ratified the Paris climate protection agreement together. The US has pledged to decrease its CO2 emissions by at least 26 percent by 2020. China lags far behind this promise: Under the agreement, its CO2 emissions will continue to rise until 2030.

New climate protection regulations represent not just requirements for industry, but also opportunities: Already today, Germany is one of the technology leaders in renewable energies and energy efficiency, and also the leading export nation for environmental technologies, accounting for 16 percent of the global market.

Energy , the largest global trade fair for networked and secure energy and mobility technologies, showcases the energy value chain in full as part of HANNOVER MESSE. A wide range of forums, conferences and special events give visitors the opportunity to learn more about the leading topics in the energy sector.
