Environmental performance in low-carbon energy systems - 0 views

  •  
    " Developing economic well-being and preserving a healthy environment are not opposed forces but do, on the contrary, have a primary relationship and require a similar life-cycle-thinking. Maximizing the efficiency of a product over its life cycle will minimize its total financial cost as well as the total environmental impact over its life cycle, according to a new report 'Evaluating environmental performance in low-carbon energy systems' by PE International for European Copper Institute. © Aania The report presents case studies which were developed to substantiate this life-cycle-thinking by delivering high level messages supporting decision making on the sustainable energy arena. The case studies provide results for several realistic - future and present - situations in regard to different scenarios and boundary conditions for energy systems. The aim is to define a common denominator that can be used as a starting point for further developments and discussions. To complement the decision-making landscape, future scenarios are also modelled - not as straight jacket by as a means to assess the influence of various trends or decisions. Choice of power grid mix - a case The case study 1, among the seven case studies, was constructed with the intention of assessing how the choice of power grid mix influences the environmental impact of producing electricity. Electric power can be produced from various renewable and non-renewable resources, and the technologies to harvest renewable resources are gaining momentum, together with the global pressure to increase their contribution to energy provision. In the EU targets have been set for 2020 to generate 20 percent of the total energy demand from renewable resources. National schemes have been set up to reach this overall goal, stricter for the more advanced and economically stable nations and laxer for the economically more disadvantaged ones. Although the target is very demanding, the potential benefits ar

US invests in Energy Frontier Research Centers | Leonardo ENERGY - 0 views

  • In August, U.S. Energy Secretary Steven Chu announced the delivery of $377 million in funding for 46 new Energy Frontier Research Centers. The centers will be hosted by universities, national laboratories, non-profit organizations, and private companies. The research domains that were chosen offer a good sampling of those technologies the US Department of Energy (DOE) sees as potentially important in the energy landscape of the future. The funded projects are focussed on: Improving the efficiency of photovoltaic systems; with particular projects dedicated to hybrid inorganic/organic PV cells and nanometre-sized PV cells Advanced nuclear techniques Carbon capture and geological storage (CCS) Hydrogen, including the production of hydrogen as well as hydrogen fuel cells Biomass, including energy-rich plants and the conversion of biomass into chemicals and fuels Energy storage systems Superconductivity (1 project)

Distribution transformer efficiency in a liberalised market | Leonardo ENERGY - 0 views

  • A widespread use of high efficiency transformers could save the world 100 TWh/year. Under normal conditions, purchasing high efficiency transformers is both economically and environmentally sound. In the liberalized European energy market however, the regulatory and financial framework obstructs utility companies from making long term investments like purchasing high efficient transformers. National regulators put pressure on utility companies to do cost cutting and do not compensate with sufficient incentives for energy efficiency. According to this paper, there is a heterogeneous treatment between generation on renewable energy and transformer efficiency. Yet the greenest kWh is still the one that is saved, even when it is compared to a kWh derived from a renewable source.

Energy Saving by Reducing No Load Loss of Distribution Transformers | Leonardo ENERGY - 0 views

  • In Japan about 16 million units of distribution transformers are in service. These transformers are expending a huge amount of energy in the form of no load loss and load loss. Among these losses, no load loss is major. No load loss can be saved dramatically by changing these transformers to amorphous transformers (i.e., amorphous metal-based transformers). This paper estimates the scope of the possible energy saving and reduction of CO2 emissions by the adoption of amorphous transformers in Japan and in China.

Impact of market liberalisation | Leonardo ENERGY - 0 views

  • Liberalization has improved the administrative efficiency of the electricity system, but what has been its impact on technical performance? Energy efficiency of the distribution system, its technical quality of supply and environmental performance are issues which where largely conspicuous in their absence in the debate, but maybe it is time to address them now. A discussion paper from Leonardo ENERGY.

Electric/hybrid cars breaking efficiency records! | Leonardo ENERGY - 1 views

  •  
    This website is about both electric and hybrid cars. It shows that both of these inventions are breaking efficiency records and are saving consumers lots of money and also protecting our environment. It's a good source and may be a key part in proving how these inventions are now impacting our environments today and how it will keep impacting it in the future.

White, green and black certificates: three interacting instruments | Leonardo ENERGY - 0 views

  • This paper presents three different types of certificates ('white' for energy savings, 'green' for renewable electricity, and 'black' for greenhouse gas reductions in the European Emission Trading Scheme). The current limited experiences with these instruments already allow to define some of the success factors for these new instruments. A synthesis of their current application presents how much energy is saved today due to these certificates, and how much green electricity is produced. A discussion on the methods for setting the targets, measuring the impacts on the market and the interaction between these different instruments concludes this paper, followed by a reminder of the proposal to create an international agency on global stewardship for climate change issues.

Estimation of the energy losses of transformers at wind turbines | Leonardo ENERGY - 0 views

  • The lower bound of generation is NOT zero, as implied by the graph, but is actually negative when the windmill is not generating. The core is excited from the HV side, just like in a distribution system. When there is no generation, the transformer actually pulls power from the grid. For renewables, you should be using transformers with amorphous metal cores which cut no load losses by 70 percent.

ICER - Art_9 - 0 views

  • Environmental concerns remain a driving force for European energy policy, as exemplified by last years’ directive on energy efficiency. The directive sets the legislative framework to achieve energy efficiency targets. Since electricity network losses comprise a significant component of electricity demand, regulatory incentives to facilitate loss reduction in electricity networks should be in place. This paper evaluates the incentives for investments in low-loss equipment in differing regulatory settings and outlines pathways to assure the proper embedding of these incentives.
