Sammanfattning : The closed greenhouse is an innovative concept in sustainable energy management. The closed greenhouse can be considered as a large commercial solar building. In principle, it is designed to maximize the utilization of solar energy through seasonal storage. In a fully closed greenhouse, there are not any ventilation windows. LÄS MER
- Detta är en avhandling från Environmental and Energy Systems Studies, Lund university
Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER

Sammanfattning : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. LÄS MER
4. Energy Savings Using a Direct-Current Distribution Network in a PV and Battery Equipped Residential BuildingDetta är en avhandling från Gothenburg : Chalmers tekniska högskola
Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
5. National Energy System Modelling for Supporting Energy and Climate Policy Decision-making: The Case of SwedenDetta är en avhandling från Gothenburg : Chalmers tekniska högskola
Sammanfattning : Energy system models can contribute in evaluating impacts of energy and climate policies. The process of working with energy system models assists the understanding of the quantita-tive relationships between different parts of the energy system and between different time periods, under various assumptions.
