The countries in the European Union have agreed to increase their percentage renewable energy sources to 20 %. To reach this goal an increase of biomass production needs to be made. One way of achieving this is by using nonnative species. Poplar in Sweden produces biomass faster …
… be used only in critical conditions. Otherwise, the system will be powered by renewable solar energy which will charge the EDLCs at the same time. The device’s architecture contains a context- and power-aware task manager, which controls the node’s low-power modes and decides …
Substratkartläggning och rötningsförsök i laboratorieskala
… climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down …
… of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative. However, there is a problem …
a study about the production environment and international competitiveness of wood pellets from British Columbia
… has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 …
? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar
… into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid. Distributed generation …
… long been a cause for analysis and debate, development and usage of so called renewable energy sources is therefore more important than ever. The energy in the electromagnetic radiation from the sun is an interesting alternative. One way of harvesting this energy is by using …
EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
… countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase. Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is …
To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow …
… through out the whole year. The electricity in the playhouse only comes from renewable energy sources and generates energy for the amusing features inside. Thanks to Boleko concepts such as energy, magnetism, friction, gravity, light reflection, mathematics and mechanics become …
… fuels and theneed for alternative energy sources aregreat. Ocean waves are a renewable andsustainable source of energy that hasbeen relatively untapped. At UppsalaUniversity research and development havebeen done for several years. Severaltypes of wave energy converters …
