Energy consumption
The significance of energy consumption for the environment depends on the amount of consumption and the energy production method. Energy conservation means savings in the consumption of electricity, heat, fuels and warm water. Energy conservation pays off, since it both saves money and reduces emissions, thus promoting sustainable development.

The majority of the Port of Helsinki’s electricity consumption is for the lighting of yards and for buildings. Some of the Port’s electricity consumption consists of the customers’ consumption, which is covered by the rent. In 2010, the Port of Helsinki’s electricity conservation was 8% better than the previous year. The heat consumption of properties has decreased significantly, as the Port of Helsinki has given up unnecessary properties.
The Port of Helsinki has been set the objective of reducing its energy consumption by two percentage points per year during the period
2008–2016. This is the city’s common energy conservation objective for all branches of administration. The Port of Helsinki has electricity conservation plans that aim to reduce electricity consumption and load on the environment.
Shore-side electricity
The Port of Helsinki examined, in co-operation with shipping companies and Helsinki Energy, all of the possibilities that shore-side electricity offers passenger ships. The goal is for the passenger and car ferries at the South Harbour to be connected to the shore-side electricity when at a berth. There is a shore side electricity connection at the Pakkahuone Quay that is available for the Defence Forces’ vessels calling Helsinki.
