The Necessity

Being energy neutral by 2050

The Paris Energy Agreement

Reducing CO2 emissions

No one will have missed that the weather patterns are becoming more extreme and the effects of global warming are taking their toll.

In order to provide a sustainable future for the planet, it is crucial that we drastically reduce our CO2 emissions, by 30% by 2035 and by 100% by 2050.

The Trias Energetica

Time to critically examine the industrial focus on energy reduction

Limit current energy consumption

The area of focus for Energy-IO

By analyzing consumption data at every level of the company, we can identify which processes can be optimized. This directly reduces CO2 emissions and often saves - enormous amounts of - energy.

Generate sustainable energy

Does not always generate the energy needed at the right moment.

Generating sustainable energy contributes significantly to CO2 reduction. However, the business cases for industrial parties are often still poor, and advice is only followed on paper. Additionally, this does not reduce wasted energy consumption.

Stop fossil fuels

Definitely a good idea, but not realistic for reducing CO2 emissions in the short term.

Many industries rely on fossil fuels such as gas. Making processes gas-free often requires a huge investment and this is sometimes simply not feasible.

About Energy-IO

Every residential house nowadays has a smart meter. They know exactly what it costs if a washing machine runs an hour shorter or longer. But in the manufacturing industry? There, they annually pay at least 250,000 euros to the energy company. But they have no idea which process or machine really runs efficiently, or is just a huge energy leak.
