    Abstract : Diverse sources of energy are becoming increasingly significant in today's world. The most common source of energy today is fossil fuels, such as coal, oil, and gas. While this energy source has many advantages, it also comes with many problems. READ MORE

  5. 3. Spectroscopy on the Dot : Photoelectron Spectroscopy and Time-Resolved Studies of Lead Sulfide Quantum Dots for Solar Cells

    Author : Tamara Sloboda; Ute B. Cappel; Andreas Lindblad; Lars Kloo; Regan Wilks; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : Renewable energy is an important topic as global energy consumption continues to rise. Because the sun emits an enormous amount of energy, solar energy is a promising source. However, most of the commercial solar cell technology is manufactured in an energy demanding process and there is a need for new, easily processed materials. READ MORE

  6. 4. System studies of biogas production : comparisons and performance

    Author : Emma Lindkvist; Magnus Karlsson; Mats Söderström; Maria Johansson; Ola Norrman Eriksson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. READ MORE

  7. 5. Towards More Coherent and Sustainable Biomass Policy: Examining European biomass-to-energy planning

    Author : Niina Kautto; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy; Biomass policy; Renewable energy; Policy coherence; National action plan; Strategic planning; European Union; Region;

    Abstract : Coordination of policies embracing biomass use has been called for in order to speed up progress towards the European Union renewable energy and climate change goals. Policy coordination and coherence is also required if the many complex and diverse issues constraining sustainable bioenergy development are to be addressed. READ MORE
