Abstract
Dette speciale undersøger, hvordan store energibesparelser bedst kan indarbejdes i det nuværende danske energisystem ved at kortlægge, hvordan forskellige typer besparelser påvirker hinanden. På den baggrund udvikles integrationsstrategier frem mod et 100 % vedvarende energisystem i 2050. Strategierne sammenlignes med Energispareaftalen for at vurdere, om aftalen driver de rette besparelser. Arbejdet består af to analyser: (1) En energisystemanalyse, der beskriver sammenhænge mellem besparelser og, kombineret med viden om besparelser og 2050-scenariet, skitserer strategierne. (2) En analyse, der sammenholder rapporterede besparelser med skøn over aftalens faktiske effekt, identificerer hvilke strategier de enkelte forsyningsselskaber anvender, og hvordan aftalen har ændret deres organisering. Første analyse viser, at det nuværende system kræver koordinerende tiltag, som påvirker kraftvarme (CHP, samtidig el- og varmeproduktion). Anden analyse viser, at Energispareaftalen godt nok giver besparelser, men ikke fortrænger fossile brændsler og derfor ikke er egnet til at nå målet om 100 % vedvarende energi i 2050.
This thesis examines how large-scale energy savings can be integrated into the current Danish energy system by mapping how different types of savings interact. Based on this, it develops integration strategies toward a 100% renewable energy system by 2050. These strategies are compared with the Energy Savings Agreement to assess whether the agreement drives the right kinds of savings. The study comprises two analyses: (1) an energy system analysis that identifies relationships between savings and, combined with knowledge of savings and the 2050 scenario, outlines the strategies; and (2) an analysis that compares reported savings with estimates of the agreement’s actual effect, identifies the strategies used by individual utility companies, and examines how the agreement has changed their organization. The first analysis finds that the current system needs coordination measures affecting combined heat and power (CHP). The second concludes that, while the Energy Savings Agreement delivers savings, it does not displace fossil fuels, making it unsuitable for achieving the 2050 target of 100% renewable energy.
